FIELD OF THE INVENTION

Certain embodiments of the invention relate to providing communication in a media exchange architecture. In particular, certain embodiments of the invention relate to providing server architectures for the registering devices and the exchange of media, data, and services between devices on a media exchange network.

BACKGROUND OF THE INVENTION

Current communication systems allow digital media to be shared between users and entities on a communication network. Although current communication systems allow digital media to be shared among users and entities on a communication network, current sharing methodologies are somewhat limiting. Current communication systems provide two primary ways that allow users to exchange digital media. A first methodology utilizes fairly interactive method by permitting a personal computer (PC) having an upstream and downstream connection to, for example, the Internet, an intranet and a local are network (LAN).
An Internet service provider ISP) may provide or issue a temporary Internet protocol (IP) address to personal computers connected to the Internet using, for example, dynamic host configuration protocol (DHCP). Some computers may also be provided with a static IP address. The personal computers may then access web sites on the Internet using a web browser and send and receive email with or without file attachments in order to exchange media, data, and services between the personal computes. Files may also be transferred over the Internet using various protocols such as file transfer protocol (FTP) and hypertext transfer protocol. File transfer protocol (FTP) allows personal computers connected to the Internet to exchange files, independently of the personal computer hardware platform. Hypertext transfer protocol allows personal computers to upload and download information between a web server hosting a web site and a personal computer.
A user of a personal computer may connect a digital media device or a media peripheral device such as a digital camera or a MP3 player to a personal computer and download or upload digital files from the digital media device to the personal computer. A media peripheral device may interface to a personal computer through a USB (Universal Serial Bus) interface in order to exchange digital media between a personal computer and the media peripheral device. Again, the digital files may be attached to emails and shared with others in such a manner.
A user may have access to digital broadcast media through a set-top-box (STB) providing predominantly one-way communication. One-way communication is particularly true in satellite-based applications and broadcast television communication systems. In this regard, broadcast media may be sent from a broadcast media provider to the set-top-box. A user of a set-top-box may also be able to order media content such as movies through specialized broadcast channels such as pay-per-view (PPV) broadcast channels via the set-top-box. However, interaction between the user and the set-top-box is, otherwise, very limited. A set-top-box may interface to a cable infrastructure, a satellite and/or digital subscriber line (DSL) infrastructure to receive and/or transmit broadcast media and to exchange access information between the infrastructure and the set-top-box.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

BRIEF SUMMARY OF THE INVENTION

Certain aspects of the invention may be found in a method and system for setting up devices for communication on a communication network. Aspects of the method for setting up devices for communication on the communication network may comprise assigning an address to a first device coupled to the communication network and transferring the assigned address to the first device. In response to receiving the transferred assigned address and/or an identifier of the first device from the first device, the received transferred assigned address and/or the identifier of the first device may be communicated to at least one communication server coupled to the communication network. The method may further comprise detecting when the first device is initially coupled to the communication network prior to assigning the address to the first device. The assigned address of the first device may be a static address, a dynamic address and/or an embedded device address such as a media access control (MAC) address.

Certain embodiments of the system for setting up devices for communication on a communication network may comprise a headend that assigns an address to a first device coupled to the communication network. The headend may be adapted to transfer the assigned address to the first device. In response to receiving the transferred assigned address and/or an identifier of the first device from the first device, the headend may communicate the transferred received assigned address and/or the identifier of the first device to at least one communication server coupled to the communication network. The headend may also be adapted to detect when the first device is initially coupled to the communication network prior to assigning the address to the first device. The assigned address of the first device may be a static address, a dynamic address and/or an embedded device address such as a MAC address. The identifier of the first device may be a digital certificate and/or a serial number.
The communication server may register the transferred assigned address and/or the identifier of the first device and may broadcast the transferred assigned address and/or the identifier of the first device throughout at least a portion of the communication network. The system may further comprise a second device located in the at least a portion of the communication network that may receive the broadcasted transferred assigned address and/or the identifier of the first device. The second device may communicate with the first device utilizing the received broadcasted transferred assigned address and/or the identifier of the first device. The second device may requests the transferred assigned address and/or the identifier of the first device from the server whenever the second device desires to communicate with the first device via the communication network. In response to the request, the second device may receive the transferred assigned address and/or the identifier of the first device from the server and accordingly transfer media between the second device and the first device utilizing the received a transferred assigned address and/or the identifier of the first device. In another aspect of the invention, the second device may requests the transferred assigned address and/or the identifier of the first device from the server whenever the second device desires to communicate with the first device via the communication network based on a known location of the first device.

FIG. 1C is a functional diagram illustrating a more specific embodiment of the broadband access headend 120 of FIG. 1B comprising a cable headend 130, in accordance with various aspects of the present invention. The cable headend 130 may be the primary interface infrastructure between users of a media exchange network, for example, a user at the first (1^st) home 104 of FIG. 1A and the Internet infrastructures, for example, 115 of FIG. 1A and 140 of FIG. 1C. The cable headend may be managed and/or operated by a cable provider and/or an Internet service provider. The cable headend 130 may comprise analog/video sources 131, a cable modem termination system (CMTS) 132, a legacy out-of-band (OOB) return path 133, upconverters/downconverters 134, a signal splitter 135, an intranet infrastructure 136, and a router/firewall 137.
The analog/digital video sources 131 may include, for example, a disk array, a web cache and/or a video cache. The upconverters/modulators 134 may be adapted to perform channelization of signals from the analog/digital video sources 131, the legacy OOB return path 133, and the cable modem termination system 132. For cable channels, channelization may occur for frequencies between 400-700 MHz. The upconverters/modulators 134 may include, for example, a quadrature amplitude modulated (QAM) modulator and an analog modulator. The signal splitter 135 may handle both digital and analog channels and include a power amplifier.
The cable modem termination system 132 may be a high-end cable modem that supports upstream and downstream communications between the cable headend 130 an multiple users having cable modems and/or media processing systems, televisions, and personal computers that are cable ready. The cable modem termination system 132 may utilize an operating system, for example, a real time operating system (RTOS), embedded operating system or other operating system such as Linux. The intranet infrastructure 136 may comprise a server for handling the flow of digital traffic through the cable headend 130 and to perform various management and control functions within the cable headend 130.
The signal splitter 135 may be adapted to interface to the upconverters/modulators 134, the cable modem termination system 132 and the legacy out-of-band return path 133. The signal splitter 135 may interface with and may pass or transport analog and digital information to a device at a user's home, for example, a cable modem and a media processing system. The analog/digital video sources 131, the legacy OOB return path 133, and the cable modem termination system 132 may interface with the upconverters/modulators 134. The intranet infrastructure 136 may interface with the analog/digital video sources 131, the cable modem termination system 132, and the router/firewall 137. The router/firewall may interface with the Internet infrastructure 140, which is not part of the cable headend 130. The Internet infrastructure 140 interfaces to the outside world, which may include intranets, WANS, MANS and a PSTN.
The functionality of the broadcast media headend 121 in FIG. 1B may be supported by the analog/digital video sources 131, the cable modem termination system 132, and the intranet infrastructure 136 in the cable headend 130 in order to process and pass broadcast media. The analog/digital video sources 131 may be configured to provide support for analog video and/or streaming digital video. For example, a MPEG stream may be generated from a file stored on the analog/digital video sources 131 and passed to the upconverters/modulators 134 to be channelized. Alternatively, the MPEG stream could originate from the Internet infrastructure 140, through the router/firewall 137, to the intranet infrastructure 136, and to the analog/digital video sources 131. The MPEG stream may then be passed or transported to the upconverters/modulators 134 to be channelized.
A digital file may be routed, via the cable modem termination system 132, to the upconverters/modulators 134 for channelization. The digital file may arrive at the cable modem termination system 132 via the Internet infrastructure 140, the router/firewall 137 and/or the intranet infrastructure 136. Also, a digital file may be transported to the cable modem termination system 132 via the signal splitter 135 from a user's home in the form of a modulated signal. The cable modem termination system 132 may then demodulate the signal and pass the resultant digital file out to the Internet infrastructure 140 via the intranet infrastructure 136 and the router/firewall 137.
The intranet infrastructure 136 within the cable headend 130 may be adapted to performs various functions including passing digital information such as digital files, digital streams, digital commands, account management such as billing, pay-per-view processing, email, provisioning, addressing and user authentication, for example, sending a signal via the cable modem termination system to decode video sent to a media processing system. The addressing may be static or dynamic such as in the case of a statically assigned IP address and a dynamically assigned IP address.
The functionality of the broadband data headend 122 in FIG. 1B may be supported by the cable modem termination system 132, the legacy out of band return path 133 and/or the intranet infrastructure 136 in the cable headend 130. Various commands, such as control commands and request commands, may be processed and transported or passed through the cable modem termination system 132. For example, a media processing system at a user's home may send a request to the cable headend 130. The request comes through the splitter 135 to the cable modem termination system 132. The cable modem termination system processes the request, possibly in conjunction with the intranet infrastructure 136. A response to the request may be passed back to the media processing system at the user's home via the cable modem termination system 132, upconverters/modulators 134, and signal splitter 135. The cable modem termination system 132 may be typically configured to communicate with a plurality of users through the signal splitter 135.
The legacy out-of-band return path 133 may be configured to process legacy out-of-band signals that arrive at the cable headend from a user's home. These out-of-band signals are separate from the broadcast channel frequencies, for example, 5-50 MHz signals that may include, for example, per-per-view commands from a user. The legacy out-of-band return path 133 may demodulate and process the out-of-band signals and, in response, may transmit other out-of-band signals back to the user via the upconverters/modulators 134 and the signal splitter 135.
The router/firewall 137 may be adapted to route signals to the correct destinations on the Internet and/or intranet infrastructures and may aid in isolating the cable headend from unwanted accesses via the Internet infrastructure 140. In this regard, isolation may be provided through the use of a firewall.
A broadband access headend in the media exchange network 100 of FIG. 1A may also comprise a digital subscriber line headend or a satellite headend.

Optionally, the media peripheral 161 may interface to the digital subscriber line modem 158. As a further option, the personal computer 159 and/or the satellite media processing system 160 may internally include a digital subscriber line modem to connect to the digital subscriber line infrastructure instead of utilizing the external digital subscriber line modem 158.
The personal computer 165 and cable media processing system 166 in the 2^nd home 164 may interface with the cable headend 151. The personal computer 165 and cable media processing system 166 may include a cable modem internally. Optionally, cable modems may be externally coupled to the personal computer 165 and/or cable media processing system 166 to interface with the cable headend 151. The media peripheral 167 may interface with the cable media processing system 166 and/or the personal computer 165 via wireless or wired connections such as a universal serial bus or an IEEE 1394 Firewire connections. Optionally, the media peripheral 167 may interface to the cable headend 151 via a cable modem. A cable infrastructure (not shown) is provided to route cable signals between the cable headend 151 and the 2^nd home 164 and between the cable headend 151 and the Internet infrastructure 154.
The satellite headend 153 essentially comprises a high-end DSL modem with supporting infrastructure such as upconverters/modulators, router/firewall and intranet infrastructure, and is operated by a satellite provider. The satellite headend 153 may be adapted to perform much of the same functionality as a cable headend. The satellite headend 153 may have the capability to communicate with users or subscribers via the digital subscriber line infrastructure 157 which may comprise a telephony network to transmit information along twisted pair (TP) copper wires. A user at the first (1^st) home 162 may receive broadcast media transmitted from an orbiting satellite to a terrestrial or land based satellite dish 163. The satellite dish 163 may be adapted to receive and pipe or otherwise communicate the received satellite signal to the satellite media processing system 160. Communicated information, for example, command data, may be transferred between the first (1^st) home 162 and the satellite headend 153 via the digital subscriber line infrastructure 157.
The digital subscriber line headend 152 essentially comprises a high-end digital subscriber line modem with supporting infrastructure for example, upconverters/modulators, router/firewall and intranet infrastructure, and is operated by a digital subscriber line provider, telephone service provider and/or cable service provider. The digital subscriber line headend 152 performs much of the same functionality as the cable headend previously described. Broadcast media may be provided to the third (3^rd) home 168 by the digital subscriber line headend 152 via digital subscriber line infrastructure (not shown) between the third (3^rd) home 168 and digital subscriber line headend 152, and/or between the digital subscriber line headend 152 the Internet infrastructure 154. Command data may also be communicated between the third (3^rd) home 168 and the digital subscriber line headend 152 in a similar manner.
In an alternative embodiment of the invention, the functionality of the media exchange servers may be distributed throughout the various elements of the media exchange network. For example, referring to FIG. 1D, the functionality of the media exchange server 155 may alternatively be distributed into any combination of devices on the media exchange network 150 including the personal computer 159, the personal computer 165, the satellite media processing system 160, the cable media processing system 166, the satellite headend 153, the cable headend 151, the digital subscriber line headend 152, and/or devices within the third (3^rd) home 168.
Other embodiments of the present invention may comprise various combinations and/or multiple instantiations of the elements of FIG. 1A and FIG. 1D, in accordance with various aspects of the present invention.
FIG. 2 is a flowchart illustrating an embodiment of a method 200 for registering a device on the media exchange network of FIG. 1A, in accordance with various aspects of the present invention. Referring to FIG. 2, in step 201 of the method 200, a device is connected to a media exchange network and is powered up. In step 202, the device may request an address from a broadband access headend on the media exchange network. In step 203, the broadband access headend assigns and provides an address to the device. In step 204, the device provides its address and its identification (ID) to a media exchange server on the media exchange network. In step 205, the media exchange server registers the address and identification (ID) of the device.
In an illustrative embodiment of the invention, with reference to FIG. 1D, a user of the media exchange network 150 at the second (2^nd) home 164 may connect the cable media processing system 166, which may be referred to as a device, to the media exchange network 150 through the cable infrastructure that interfaces with the cable headend 151 or broadband access headend. Upon power up, the cable media processing system 166 may undergo a registration process with the cable headend 151. Associated with the registration process are the timing and synchronization, ranging, and cable modem provisioning including Internet protocol (IP) address assignment, for example, which may be based on service functionality provided by the cable headend 151 and the type of cable data standard or protocol employed.
Notwithstanding, the intranet infrastructure of FIG. 1C of the cable headend 151 may assign and transmit an IP address to the cable media processing system 166. The address may be a permanent, fixed IP address or may be a temporary IP address provided using dynamic host configuration protocol (DHCP). With DHCP addressing, a server in the intranet infrastructure of the cable headend may be adapted to allocate IP addresses based on which devices are active on the network. The intranet infrastructure may control the IP addressing such that the assigned IP address is transparent to the outside world. In this regard, the server may be adapted to perform a translation of the IP address to the Internet infrastructure.
Next, the cable media processing system 166 may be configured to ping the media exchange server 155 and may transmit its IP address and identification information (ID) to the media exchange server 155 via the cable headend 151 and Internet infrastructure 154. The cable media processing system may include software that may be configured to recognize or identify the IP address of the media exchange server 155 and perform the pinging. The software may be a part of a media exchange software (MES) platform that provides much of the media exchange functionality for the cable media processing system 166 on the media exchange network 150. The identification (ID) may be in the form of, for example, a digital certificate or a serial number that is installed as firmware or hardware in the cable media processing system 166. The cable media processing system 166 may be aware of the IP address of the media exchange server 155 so that it may transmit its IP address and ID to the media exchange server 155.
Accordingly, the media exchange server 155 may register the IP address and ID of the cable media processing system. As a result, the media exchange server 155 may recognize the cable media processing system 166 as a legitimate device on the media exchange network 150. Other users of the media exchange network 150 may be able to communicate with the cable media processing system 166 with the aid of the registered information and functionality of the media exchange server 155. In one embodiment of the invention, one IP address and/or ID of the cable media processing system 166 may be broadcasted to at least selected other networking entities or components on the media exchange network 150.
Other devices connected to the media exchange network 150 may be registered by the media exchange server in a similar manner. Multiple media exchange servers may be present at various strategic locations in the media exchange network and play a part in device registration. In accordance with an embodiment of the invention, the multiple servers may communicate with each other by maintaining a bridge routing table between servers. In this regard, a particular server may have information regarding details of how to communicate with a neighboring server. Also, the functions of the media exchange server may be distributed throughout devices on the media exchange network, such as personal computers and media processing systems in the home or headends, and accomplish the registration of devices.
By registering devices on a media exchange network, the registered devices now have a means to communicate with each other. A registered device on the media exchange network 150 may access a list of other registered devices on the media exchange network 150 from the media exchange server 155. As a result, a registered device may establish a communication link with other registered devices. For example, if the cable media processing system 166 at the second (2^nd) home and the personal computer 159 at the first (1^st) home are both registered with the media exchange server 155, then the user of the cable media processing system 166 may access this registered information and utilized the registration information to push or otherwise communicate media to the personal computer 159 over the media exchange network 150. That is, the media exchange server 155 knows the IP addresses of the source and desired destination. Therefore, the media exchange server 155 may coordinate the exchange of media between the two registered devices.
As another example, a user of the personal computer 159 at the first (1^st) home 162 may desire to push media to the cable media processing system 166 at the second (2^nd) home 164. The user of the personal computer 159 may know the name and street address of the user of the cable media processing system 166 at the second (2^nd) home 164 and provide this name to the media exchange server 155. The personal computer 159 may be registered with the media exchange server 155 and the cable media processing system 166 may be registered with the media exchange server 156. As a result, the media exchange server 155 may not have the registration information of the cable media processing system 166 at the second (2^nd) home 164 since the cable media processing system 166 is registered with the media exchange server 156. In this regard, the media exchange server 155 may have to request and/or query the media exchange server 156, via the Internet infrastructure, about the existence of, for example, registration information, the cable media processing system 166 at the second (2^nd) home based on the provided user's name and street address. Information about the cable media processing system 166 at the second (2^nd) home is routed by the media exchange server 156 to the media exchange server 155. The personal computer 159 at the first (1^st) home may utilize the information about the cable media processing system 166 in the media exchange server 155 to route media to the cable media processing system 166 at the second (2^nd) home.
Certain other embodiments of the invention may be found in a method for setting up devices for communication on a communication network. Aspects of the method may comprise the steps of detecting when a first device is initially coupled to the communication network and assigning an address to the first device when it is coupled to the communication network. The assigned address may then be transferred to the first device. In response to receiving the transferred assigned address and/or an identifier of the first device from the first device, the received transferred assigned address and/or the identifier of the first device may be communicated to at least one communication server coupled to the communication network. In a multiserver environment, the received transferred assigned address and/or the identifier of the first device may be communicated to a plurality of servers coupled to the communication network. The steps of assigning, transferring, communicating and/or detecting the first device may be achieved by a headend, which may be coupled to the communication network and provides access to the communication network for the first device. The assigned address of the first device may be a static address, a dynamic address and/or an embedded device address such as a media access control (MAC) address. The identifier of the first device may be a digital certificate and/or a serial number.
In accordance with an aspect of the invention, the communication server may register the transferred assigned address and/or the identifier of the first device and broadcast the assigned address and/or the identifier throughout at least a portion of the communication network. The broadcasted transferred assigned address and/or the identifier of the first device may be received by a second device which may be located in that portion of the communication network. The second device may communicate with the first device by utilizing the received transferred assigned address and/or the identifier of the first device that is broadcasted.
The transferred assigned address and/or the identifier of the first device may be received from the server by a second device whenever the second device desires to communicate with the first device via the communication network. In response to the request, the second device may receive the transferred assigned address and/or the identifier of the first device from the server. Accordingly, the second device may transfer media between the second device and the first device utilizing the received assigned address and/or the identifier of the first device. In another aspect of the invention, the transferred assigned address and/or the identifier of the first device may be requested from the server by the second device whenever the second device desires to communicate with the first device via the communication network based on a known location of the first device.
A further embodiment of the invention may provide a system for setting up devices for communication on a communication network. Certain aspects of the system may comprise a headend that may be configured to detect when a first device is initially coupled to the communication network and assign an address to a first device coupled to the communication network. The headend may be adapted to transfer the assigned address to the first device and in response to receiving the transferred assigned address and/or an identifier of the first device from the first device, the headend may communicate the transferred received assigned address and/or the identifier of the first device to at least one communication server coupled to the communication network. The assigned address of the first device may be a static address, a dynamic address and/or an embedded device address such as a MAC address. The identifier of the first device may be a digital certificate and/or a serial number. The communication server may register the transferred assigned address and/or the identifier of the first device and may broadcast the transferred assigned address and/or the identifier of the first device throughout at least a portion of the communication network.
The system may further comprise a second device located in a portion of the communication network that may receive the broadcasted transferred assigned address and/or the identifier of the first device. The second device may communicate with the first device utilizing the received broadcasted transferred assigned address and/or the identifier of the first device. The second device may also be configured to request the transferred assigned address and/or the identifier of the first device from the server whenever the second device desires to communicate with the first device via the communication network. In response to the request, the second device may receive the transferred assigned address and/or the identifier of the first device from the server and accordingly transfer media between the second device and the first device utilizing the received a transferred assigned address and/or the identifier of the first device. In another aspect of the invention, the second device may requests the transferred assigned address and/or the identifier of the first device from the server whenever the second device desires to communicate with the first device via the communication network based on a known location of the first device.
A major challenge is to be able to transfer and share many different types of digital media, data, and services between one device/location and another with ease while being able to index, manage, and store the digital media and data.
For example, it is desirable to be able to distribute and store many types of digital media in a PC and/or television environment in a user-friendly manner without requiring many different types of software applications and/or unique and dedicated interfaces. Any networking issues or other technical issues should be transparent to the users. It is also desirable to take advantage of existing hardware infrastructure, as much as possible, when providing such capability.
In an embodiment of the present invention, a media exchange network is provided that enables many types of digital media, data, and/or services to be stored, indexed, viewed, searched for, pushed from one user to another, and requested by users, using a media guide user interface. The media exchange network also allows a user to construct personal media channels that comprise his personal digital media (e.g., captured digital pictures, digital video, digital audio, etc.), request that third-party media channels be constructed from third-party digital media, and access the media channels pushed to him by other users on the media exchange network.
PC's may be used but are not required to interface to the media exchange network for the purpose of exchanging digital media, data, and services. Instead, set-top-boxes or integrated MPS's (media processing systems) may be used with the media exchange network to perform all of the previously described media exchange functions using a remote control with a television screen.
Current set-top-boxes may be software enhanced to create a MPS that provides full media exchange network interfacing and functionality via a TV screen with a TV guide look-and-feel. PC's may be software enhanced as well and provide the same TV guide look-and-feel. Therefore, the media exchange network supports both PC's and MPS's in a similar manner. Alternatively, a fully integrated MPS may be designed from the ground up, having full MPS capability.
In the case of an MPS configuration, the user takes advantage of his remote control and TV screen to use the media exchange network. In the case of a PC configuration, the user takes advantage of his keyboard and/or mouse to use the media exchange network.
An MPS or enhanced PC is effectively a storage and distribution platform for the exchange of personal and third party digital media, data, and services as well as for bringing the conventional television channels to a user's home. An MPS and/or PC connects to the media exchange network via an existing communication infrastructure which may include cable, DSL, satellite, etc. The connection to the communication infrastructure may be hard-wired or wireless.
The media exchange network allows users to effectively become their own broadcasters from their own homes by creating their own media channels and pushing those media channels to other authorized users on the media exchange network, such as friends and family members.
FIG. 3 comprises a media exchange network 300 for exchanging and sharing digital media, data, and services in accordance with an embodiment of the present invention.

The MES platform 311 provides multiple capabilities including media “push” capability, media “access” capability, media channel construction/selection, image sequence selection, text and voice overlay, channel and program naming, inter-home routing selection, authorship and media rights management, shared inter-home media experience, billing service, and an integrated media guide interface providing a TV channel guide look-and-feel.
The external processing hardware support 305 comprises at least one server such as a centralized internet server, a peer-to-peer server, or cable head end. The server may alternatively be distributed over various hosts or remote PC's. The MES platform 311 may also reside on the external processing hardware support server 305. The remote media storage 306 may comprise user media storage and distribution systems 313 and/or third party media storage and distribution systems 314.
The communication infrastructure 304 may comprise at least one of internet infrastructure, satellite infrastructure, cable infrastructure, dial-up infrastructure, cellular infrastructure, xDSL infrastructure, optical infrastructure, or some other infrastructure. The communication infrastructure 304 links the user's home 303, parent's home 310, remote media storage 306, and remote location office 308 to each other (i.e., the communication infrastructure 304 links all users and service providers of the media exchange network 300).
The various functions 315 of the media exchange network 300 comprise generating personal network associations, personal storage management, media capture device support, security/authentication/authorization support, authorship tracking and billing and address registration and maintenance. These media exchange management functions 315 may be distributed over various parts of the media exchange network 300. For example, the personal network associations and personal storage management functions may be integrated in the PC 301 at the user's home 303.
FIG. 4 illustrates an example of personal media exchange over a media exchange network 400 in accordance with an embodiment of the present invention. In step 1, the media exchange software (MES) platform 401 is used to construct personal media channels on a PC 402 by a user at “my house” 403. For example, with various media stored on the PC 402 such as digital pictures 404, videos 405, and music 406, the MES platform 401 allows the digital media to be organized by a user into several channels having a media guide user interface 407 on the PC 402.
In step 2, the user at “my house” 403 pushes a media channel 408 (e.g., “Joe's Music”) to “brother's house” 409 and pushes two media channels 410 and 411 (e.g., “Vacation Video” and “Kid's Pictures”) to “Mom's house” 412 via a peer-to-peer server 413 over the internet-based media exchange network 400. “Brother's house” 409 includes a first MPS 414 connected to the media exchange network 400. “Mom's house” 412 includes a second MPS 415 connected to the media exchange network 400. The MPS's 414 and 415 also provide a media guide user interface 407.
In step 3, brother and/or Mom access the pushed media channels via their respective media processing systems (MPS's) 414 and 415 using their respective MPS TV screens and remote controls.
FIG. 5 illustrates an example of third-party media exchange over a media exchange network 500 in accordance with an embodiment of the present invention. In step 1, a PC-initiated third-party request is made by a first party 501 via an internet-based media exchange network 500 using a media guide user interface 502 on a PC 503. In step 2, an anonymous delivery of the requested third-party channel 504 is made to a second party 505 via the internet-based media exchange network 500. In step 3, the second party 505 accesses the third-party channel 504 using a media guide user interface 506 on a TV screen 507 that is integrated into an MPS 508.
Similarly, in step A, an MPS-initiated third-party request is made by a second party 505 via an internet-based media exchange network 500 using a media guide user interface 506 on a TV screen 507 using a remote control 509. The second party 505 may key in a code, using his remote control 509, that is correlated to a commercial or some other third party broadcast media. In step B, an anonymous delivery of the requested third-party channel 504 is made to a first party 501 via the internet-based media exchange network 500. In step C, the first party 501 accesses the third-party channel 504 using a media guide user interface 502 on a PC 503.
FIG. 6 illustrates a media guide user interface 600 in accordance with an embodiment of the present invention. The media guide user interface 600 may be displayed on a TV screen 608 and controlled by a remote control device 609. Also, the media guide user interface 600 may be displayed on a PC monitor and controlled by a keyboard or mouse.
The media guide user interface 600 may be configured not only for conventional TV channels but also for personal media channels 601 that are constructed by a user of a media exchange network, friend's and family's media channels 602 constructed by friends and family, and third party channels 603 that are constructed by third parties either upon request by a user of a media exchange network or based on a profile of a user.
The personal media channels 601 may include, for example, a “family vacations channel”, a “kid's sports channel”, a “my life channel”, a “son's life channel”, a “my music channel”, and a “kid's music channel”. The friends and family media channels 602 may include, for example, a “brother's channel”, a “Mom's channel”, and a “friend's channel”. The third party media channels 603 may include, for example, a “Sears Fall sale channel” and a “car commercials channel”.
Each media channel may correspond to a schedule 604 showing, for example, a week 605 and a year 606. For example, under the “kid's sports channel”, Ty's soccer game could be scheduled to be viewed on Tuesday of the current week 605 and current year 606. For each media channel, a sub-menu 607 allows for selection of certain control and access functions such as “play”, “send to list”, “send to archive”, “confirm receipt”, “view”, “purchase”, and “profile”.
FIG. 7 illustrates possible multiple instantiations of a media guide user interface 700 in accordance with an embodiment of the present invention. The media guide user interface 700 may be viewed with a schedule having formats of, for example, “month, year”, “week#, year”, “day, week#”, or “hour, day”.
Referring to FIG. 8, a user of a media exchange network may push a media channel (e.g., “Vacation in Alaska Video”) to a friend who is on the same media exchange network. The media guide user interface 800 may give the friend several options 801 for how to accept and download the pushed media in accordance with an embodiment of the present invention.
For example, a first, most expensive option 803 may be “Express Delivery” which would deliver the pushed media to the friend in 18 minutes using queuing and cost $1.20, for example. The pushed media may be stored in a file in an MPEG 2 format that was recorded at a rate of 4 Mbps, for example. Queuing comprises buffering and delivering a previous part of the media and then buffering and delivering a next part of the media. For example, a first six minutes of the “Vacation in Alaska Video” may be buffered and delivered first, then a second six minutes may be buffered and delivered next, and so on until the entire media is delivered.
A second, less expensive option 802 may be “Normal Delivery” which would deliver the pushed media in 2 hours and 13 minutes without queuing and cost $0.59, for example. The pushed media may be stored in a file in an MPEG 2 format that was recorded at a rate of 1.5 Mbps, for example.
A third, least expensive option 804 may be “Overnight Delivery” which would deliver the pushed media by the next morning and cost only $0.05, for example. The pushed media may be stored in a file in an MPEG 2 format that was recorded at a rate of 19 Mbps and stored on a server, for example.
