technical field

The following description relates to a multimedia system such as an audio video (AV) system utilizing an optical disc drive (ODD), and additionally, a platform-based smart television (TV) capable of controlling the ODD and processing digital data.

Background technique

With recent advances in platform-based audio video (AV) devices such as smart televisions (TVs), which are high-performance hardware-software devices utilizing a central processing unit (CPU) and an operating system (OS), research, there is increasing interest in such platform-based AV devices. Through research and development, smart TVs have become interactive media that provide over-the-air programs and various contents accessed through the Internet by connecting to the Internet. A typical ODD for a general TV or a recently released or researched smart TV has a structure similar to one complete playback device as a source for providing fully reproduced audio/image information to the TV. A conventional ODD includes a front end that processes radio frequency (RF) signals from an internal disc and a back end that processes multimedia signals such as audio/image signals from digital raw data output from the front end. The back end of a traditional ODD includes a decoder chip and peripheral circuits for separating and decoding multimedia signals. For example, multimedia signals may include audio/image signals. The reproduced audio/image signal decoded by the conventional ODD is usually sent to a TV through a high-definition multimedia interface (such as HDMI) as a digital AV output interface.

Since a smart TV uses a CPU that drives an OS for the general purpose of accessing and executing web content and various multimedia via the Internet, instead of using a digital signal processor (DSP) that performs a specific given function, a smart TV can use and utilize the CPU Related benefits for economical and efficient use of ODD. For example, the CPU can appropriately modify the interface structure between the smart TV and the ODD that can be additionally applied to or incorporated into the smart TV.

An optical disc drive (ODD) is a good source of content that can further increase the functionality of such smart TVs.

FIG. 1 is a block diagram showing an example of a basic concept of an Audio Video (AV) system 10 as a multimedia system. The AV device refers to a platform-based device including a central processing unit (CPU) and an operating system (OS) that may be incorporated into a multimedia system. As an example, the AV device may be a set-top box or a smart television (TV). Next, the AV system 10 using the smart TV will be explained.

Referring to FIG. 1, an AV system 10 includes an optical disk drive (ODD) 11 and a smart TV 12 on which wireless, cable broadcast programs or other signals input to the smart TV can be viewed.

ODD 11 is operatively connected to smart TV 12 through interface device 13. The smart TV 12 includes a decoder or codec device 12a that decodes digital data output from the ODD 11. The digital data decoded by the codec device 12a may be, for example, raw data or data that has been processed by other devices. The smart TV also includes an ODD controller 12b that controls the ODD 11, and an OS device 12c that provides an operating environment in which the codec device 12a and the ODD controller 12b operate. The smart TV includes a multimedia (M/M) output device 12f including a display unit and a speaker system for outputting at least one of an image signal and an audio signal. The OS device 12c includes a CPU and at least one storage device. As a non-limiting example, a storage device may include boot-read-only memory (ROM), random-access memory (RAM), and memory for storing software codecs or a graphical user interface (GUI), such as flash memory or a hard disk drive (HDD). The interface device 13 comprises at least two operatively connected terminals (or connection devices) adapted to send and receive data. The terminal on the ODD side is called the slave interface 13a, and the terminal on the smart TV side is called the master interface 13b.

For example, according to the example shown in FIG. 1, the ODD 11 that provides digital data such as raw data to the smart TV 12 is driven by the ODD controller 12b, wherein the ODD controller 12b utilizes the CPU of the smart TV 12 on the OS device 12c to drive.

FIG. 2 is a block diagram showing an example of the ODD 11 of the AV system 10 of FIG. 1 . As shown in FIG. 2, the ODD 11 of the AV system 10 (ie, such as shown in FIG. 1) may include an optical pickup 11a that transmits or reads information from the medium 1. The medium 1 can be, for example, an optical disc. The ODD 11 may also include a front-end system 11b and an interface device 13a operatively connected to the front-end system 11b. The front-end system 11b may include: an RF amplifier 'a' which amplifies or processes a signal output from the optical pickup 11a; a servo unit 'b' which controls the tracking and focusing mechanism of the optical pickup 11a; and an optical pickup controller' c', which controls the RF amplifier 'a' and servo unit 'b'. In contrast, for traditional ODD, ODD 11 does not include the back-end system. The front-end system 11b may also include a current/voltage amplifier provided at the front-end of the RF amplifier 'a'. As an example, the RF amplifier 'a' outputs a digital signal obtained by amplifying a high frequency signal to a master device such as the smart TV 12 or a high frequency signal through a slave interface 13a. In other words, for example, the RF amplifier 'a' may process a signal received from the optical pickup 11a. Such processing may include amplifying high frequency signals. The RF amplifier can then transmit the digital signal to the host device. The slave interface 13a is used not only for outputting high-frequency signals, but also for receiving ODD control signals output from the master device. For example, the slave interface 13a may receive an ODD control signal output from the master device, and transmit such an ODD control signal to the optical pickup controller 'c'. The master device that transmits the ODD control signal to the slave interface 13a may be, for example, a smart TV.

Interface standards over which an interface device may operate include, by way of non-limiting examples, USB and SATA. Correspondingly, the slave interface 13a on the ODD side and the master interface 13b on the smart TV side can be designed to conform to the standard USB or SATA. Also, the slave interface 13a and the master interface 13b may conform to various wireless interface standards such as WiFi and Bluetooth. In other words, the optical disc device and the smart TV can communicate through hardware electronic connection or wirelessly. USB, SATA, WiFi, and Bluetooth interface standards are just examples of standards over which to communicate.

As described above, the smart TV extracts image/audio signals (data) by processing digital data received via the interface device 13 . Image/audio signals can be extracted (decoded) by a digital AV signal processing device including a core hardware codec and a software codec. The digital data received via the interface device 13 may be raw data. Image/audio signals are output through at least one of a display unit and a speaker system. A decoder included in a digital AV signal processing device includes a codec using various standards for encoding and decoding various contents provided on a medium (for example, in the form of a disc). Various standards may include MPEG2, H.264, and VC-1 as examples.

The standard H.264 is a digital video codec standard with a very high data compression rate, called MPEG4 Part 10 or Advanced Video Coding (AVC). Standard H.264 is the product of a collaboration called the Joint Video Team (JVT) of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). Therefore, standard ITU-T H.264 and standard ISO/IEC MPEG4 Part 10 (formally ISO/IEC 14496-10) have the same technical content. The standard H.264/AVC was developed to provide good video quality at a much lower bit rate than previous standards such as MPEG2, H.263 and MPEG4 Part 2. After completing the standard H.264/AVC in 2003, in the first project to develop the standard H.264, JVT developed a standard called Fidelity Range Extension (FRExt) (version 7 in 2007). These developments enable higher quality video encoding by supporting increased precision in sampling bit depth and higher resolution color information, including sampling structures known as YUV4:2:2 and YUV4:4:4. Also, Scalable Video Coding (SVC) mode (Version 8 in 2007) is additionally supported, and Multi-View Video Coding (MVC) that can use multiple cameras is added in 2009.

The medium 1 may be a Blu-ray Disc (BD) for providing various contents. For example, BD is an optical storage medium developed by the Blu-ray Disc Association (BDA) led by Sony for storing data such as high definition (HD) video. Since such BDs use laser light having a wavelength of 405 nm much shorter than that of a digital video disc (DVD) in order to read stored data, BDs can store more data than DVDs despite the same size of BDs and DVDs. For example, a BD having a diameter of 12 cm and including a single-layer recording surface can store 25 gigabits (GB) of data, while a BD having a dual-layer disc can store 50 GB of data. Such a BD can be improved into a BD for storing computer data (BD-ROM), a recordable BD (BD-R), and a rewritable BD (BD-RE). Various copy prevention technologies for preventing illegal reproduction of video data stored in BDs have been developed. Since such copy prevention techniques may be used differently depending on the disk, even if one copy prevention technique is ineffective for one disk, access to the copy prevention techniques of other disks may not be allowed. Also, since a BD-ROM manufacturer can be easily identified by using a watermark technique, unauthorized companies can be prevented from manufacturing discs without permission.

Accordingly, ODD 11 may be an ODD that drives and reads and/or writes BDs. ODD can be designed to be compatible with existing media formats. For example, an ODD may be designed to be compatible with compact discs (CDs) or DVDs. ODD 11 is also compatible with CD, DVD and BD.

Codecs compress audio and image data. The performance of a codec is dependent on several factors including the amount of time the codec takes to perform the rendering, the resolution at which the codec compresses the audio and/or image data, and the amount of storage space that may need to be provided for the compressed audio and/or image data. factor. Codecs can be classified into lossy codecs and lossless codecs. All ODDs can support codecs utilizing standards such as MPEG2, H.264/AVC and SMPTE VC-1. For example, a codec utilizing MPEG2 is used in DVD, and it is compatible with other versions. A codec utilizing H.264/AVC has been developed as a codec of a subsequent version of MPEG4 using MPEG and VCEG. The codec utilizing VC-1 is an evolved codec developed under the leadership of Microsoft. A medium 1 such as a BD-ROM that stores image and audio data can use one of the above three codecs. Multiple codecs can be embedded in one header (content) at the same time.

For example, the AV system 10 of FIG. 1 may include all or some of the codecs identified above. The AV system 10 may include a codec for BD. Also, for better compatibility, the AV system 10 may include codecs corresponding to both DVD and BD. Codecs may be supported by hardware codecs (eg, through a multifunction codec (MFC) chip) and software codecs. For example, some codecs may be supported by a hardware codec such as an MFC chip, while the rest may be supported by a software codec loaded on a storage medium (eg RAM). Codecs supported in software can be registered and updated in the storage device of the AV system 10 . For example, the storage device of the AV system can be HDD or flash memory. Software codecs can be registered and updated using the program installation process. For example, if a software codec is used, a load on the system hardware that provides the basic functionality of the OS probing OS device 12c may be used. Moreover, smart TVs can update codecs by communicating with various data servers on the Internet. For example, OS device 12 may automatically search for new or updated available codecs. The OS device 12 may search for new or updated codecs according to predetermined conditions such as power-on of the smart TV or use of the ODD. Alternatively, OS device 12 may search for new or updated codecs according to a predetermined schedule, such as daily, weekly, monthly. As an example, at least one of a plurality of codecs corresponding to a plurality of multimedia data standards may be included in a hardware codec and a software codec in an overlapping manner. As an example, all codecs may be included in a hardware codec and/or software codec in an overlay. Alternatively, as an example, all codecs may be supported only by software codecs. Alternatively, as an example, all codecs may be supported only by hardware codecs.

FIG. 3 is a diagram showing an example of the smart TV 12 of the AV system 10 of FIG. 1 .

The smart TV 12 can be connected to the ODD 11 through the interface device 13 using a wireless communication standard such as WiFi or Bluetooth or a wired communication standard such as USB or SATA. The smart TV 12 including a computer structure corresponding to the OS device 12c also includes a digital multimedia signal processing device 12e that processes digital signals such as raw data. Digital multimedia signal processing equipment can also process preprocessed data. The digital multimedia signal processing device 12e may include a hardware part 12h having an MFC chip 12a' corresponding to a hardware codec. The digital multimedia signal processing device 12e may also include a software part 12d. The software part 12d may include a software codec 12a", and an ODD controller 12b corresponding to the GUI.

Since the software part 12d includes the ODD controller 12b and the software codec 12a" as software, the codec device 12a of FIG. Software/hardware based codec mechanism.

As an example, the digital multimedia signal processing device 12e may only include one of the MFC chip 12a' and the software codec 12a". Therefore, all codecs may be supported only by the MFC chip 12a' or the software codec 12a" . In other words, if the digital multimedia signal processing device 12e includes only a hardware codec (such as the MFC chip 12a'), the hardware codec can support all codecs. Alternatively, if the digital multimedia signal processing device 12e includes only the software codec 12a", the software codec may support all codecs.

However, if the digital multimedia signal processing device 12e includes both a hardware codec (such as an MFC chip 12a') and a software codec 12a", each of the software codec and the hardware codec can support all codecs or a subset of all codecs. As an example, when a codec supported by a hardware codec is combined with a codec supported by a software codec, then all codecs can be supported.

The OS device 12c includes system hardware, an OS loaded on the system hardware, and a porting interface loaded on the OS. System hardware may include a CPU and at least one storage device. For example, the storage device may include a non-volatile storage device such as RAM, flash memory (media), HDD, or the like.

The digital multimedia signal processing device 12e for processing digital AV signals may include a hardware part 12h and a software part 12d. The hardware part 12h may include an MFC chip 12a', and the software part 12d may include an ODD controller 12b and a software codec 12a". As an example, the ODD controller 12b may be a GUI through which a user interacts with a digital multimedia signal processing device 12e interact. As an example, the software codec 12a" processes digital data and processes multimedia signals such as audio signals and/or image signals.

The software part 12d including the software codec 12a" may be stored in a program storage device contained in the system hardware 12c of the smart TV 12. The program storage device may be HDD, flash memory, etc. The software part 12d is passed through the The control is loaded onto memory (eg, RAM) of the system hardware 12c to be activated.

Smart TV 12 may include network equipment. For example, smart TV 12 may include Internet appliance 12g. Internet device 12g may be Ethernet based. Also, a network device may be a separate source provider. Thanks to the Internet device 12g, IPTV or Internet information can be accessed. Also, the smart TV 12 may include an M/M output device 12f including a display unit. The display unit may be LCD, LED, plasma, etc. Smart TV 12 may also include a graphics processor unit that drives the display unit, a speaker system that receives audio signals and converts radio frequencies to audio, and an audio processor unit that electrically drives the speaker system. For example, a graphics processor unit may process 2D images and/or 3D images, and a display unit may display 2D images and/or 3D images accordingly.

FIG. 4 shows an example of the architecture of the smart TV 12. For example, a smart TV may include an OS device with system hardware including at least one of RAM, ROM (eg, boot ROM), HDD, flash memory, and the like. Smart TVs may also include CPUs such as x86, ARM, MIPS developed by Intel, or these may be installed in the form of a System on Chip (SoC). The OS installed on the system hardware may be any one of open-source OSs such as Android, Apple's iOS, baba developed by Samsung, Linux as a development OS, and the like. The software portion 12d may comprise a virtual machine (VM). For example, if the OS of the content provided from the ODD 11 is different from that of the smart TV 12, the VM migrates the content. Similarly, if the OS of the content provided from the OS of the smart TV 12 is different from that of the ODD 11, the VM migrates the content. For example, the VM can be a Java, Dalvik, baba, or Linux-enabled VM. The ODD controller 12b of the software part 12d may include a playback controller and registers storing ODD information. If the ODD 11 is an ODD for BD, the ODD controller 12b may further include an Advanced Content Access System (AACS) engine for copy prevention, a BD+ engine as a BD copyright management system, a BD MV module for MPEG2, and playback BD-J module for MPEG2, H.264 and VC-1.

A hardware codec (eg, MFC chip 12a') driven by the OS device 12c can support MPEG2, MPEG4, H.264, and VC-1 for reproducing contents of BD. For example, codecs not supported by the MFC chip 12a' may be supported by the software codec 12a" contained in the software part 12d as described above. Alternatively, all codecs may be supported by a hardware codec such as MFC chip 12a'). Alternatively, as an example, the hardware part 12h may not include a hardware codec (such as the MFC chip 12a'). As a result, the software part 12 may support all codecs.

FIG. 5 shows an example of the architecture of, for example, a smart TV 12 including a BD-ROM player as an ODD 11. As shown in Figure 5, the hardware and software send and receive data between them over a number of interconnects. Each of the plurality of internal connection lines is shown in FIG. 5 as an elongated line arranged in a horizontal direction.

As an example, the smart TV 12 of the AV system 10 may include an OS device 12c including a graphics processing unit (GPU), CPU, system timer, boot ROM, and RAM. Image/audio sources such as BD-ROM and local storage may be connected to the source internal connection 15 through the interface device 13 using communication standards such as USB, SATA, WiFi or Bluetooth. Also, a broadcast signal, a remote controller, and Ethernet can be connected to the source internal connection line 15 .

The broadcast signal passes through a tuner (for example, a TV tuner or a DTV tuner), a stream processor, and the like. The signals are processed and image signals and/or audio signals are reproduced in a video decoder and an audio decoder. Video codecs can be supported by hardware codecs. A medium such as a BD-ROM can store digital data such as raw data. The AV system 10 can read such digital data. For example, the ODD may read the digital data and provide the digital data through the interface device 13 using a communication standard. For example, the communication standard may be USB, SATA, WiFi or Bluetooth. A reproducing device as a BD-ROM application environment for reproducing original data is supported by the software part 12d, and may include a High Definition Movie Mode (HDMV) module and/or a BD-J module.

For example, an HDMV module may include a command handler. A BD-J module may include a Java VM and an application manager. The HDMV module applies to high-resolution movies using MPEG2. The BD-J module can support bonus content (bonus content) of a BD that supports Java Media Engine (ME) in an interactive manner. In other words, the BD-J module may support BD's bonus content to allow users to interact with such bonus content. A BD-ROM player supported by the BD-ROM environment through functions and application programming interfaces (APIs) may include a playback control engine, a presentation engine, and the like. For example, a playback control engine can render/manage a particular stream, and a rendering engine can display that particular stream on a display.

The BD engine controls data to be generated, managed and called. The Media Engine (ME) performs various functions related to media. For example, the ME controls a BD-ROM and a local storage unit (for example, an external HDD or flash memory connected through the interface device 13 using a communication standard such as SATA, USB, or Bluetooth), searches a network, etc., and manages media. For example, ME for BDs and DVDs may be the basic engine that enables BDs and DVDs to be accessed in order to perform functions such as reading data.

For example, during BD or DVD playback, if information is provided through a navigation stream as an interactive stream between the user and the rendering engine, the rendering engine may provide a subtitle stream and a composite stream including video and audio according to user input. For example, the user may input user input with the viewer pressing various buttons of the remote control. The navigation engine can determine which content is to be reproduced next time, and send the determination result to the presentation engine.

Codecs are included in platform-based AV equipment such as TVs, or utilize set-top boxes. In other words, on the one hand, ODD does not include separate codecs. The ODD directly transmits digital data obtained from a medium such as a disc to the AV equipment. Digital data obtained from a medium may be, for example, raw data. The AV equipment controls the ODD by using an ODD controller included in the AV equipment, and reproduces or extracts multimedia signals such as image/audio data by using a digital AV signal processing device that stores raw data obtained from the ODD. Accordingly, an ODD may include a separate mechanical device and an interface device that controls the mechanical device and transmits digital data (eg, raw data). According to one aspect, the ODD does not include, for example, a backend part comprising a hardware decoder. As a result, manufacturing costs are reduced.

As an example, an AV device can register and update GUI and software codec by utilizing ODD, HDD, flash memory, etc., and can flexibly respond to any new GUI or codec. Also, since the original data as digital data obtained from the ODD can be directly generated by using a digital AV signal processing device, the cost increase caused by removing the back-end part from the ODD is not much. According to one aspect, since ODD provides pure raw data, no hardware porting or software porting for maintaining compatibility with AV equipment such as TVs or set-top boxes is required.

According to the above-described examples, a multimedia system that can economically and efficiently use an optical disk drive (ODD) can be provided. The units described herein can be implemented using hardware components and software components. For example, microphones, amplifiers, bandpass filters, audio digitizers, and processing devices. may utilize devices such as processors, controllers and arithmetic logic units, digital signal processors, microcomputers, field programmable arrays, programmable logic units, microprocessors, or any other device capable of responding to and executing instructions in a defined manner A processing device is implemented by one or more general-purpose or special-purpose computers. A processing device may run an operating system (OS) and one or more software applications running on the OS. A processing device may also access, store, manipulate, process and generate data in response to the execution of software. For the sake of simplicity, the singular form is used to describe the processing device, however, those skilled in the art will understand that the processing device may include multiple processing elements and multiple types of processing elements. For example, a processing device may include multiple processors or a processor and a controller. Also, different processing configurations are possible, such as parallel processors.

Software may include a computer program, a piece of code, instructions, or some combination thereof, to instruct or configure a processing device, individually or collectively, to operate as desired. Software and data may be contained permanently or temporarily in any type of machine, component, physical or virtual device, computer storage medium or device, etc., or in a propagating signal wave capable of providing instructions or data to or being interpreted by a processing device middle. The software can also be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. Specifically, software and data may be stored by one or more computer-readable recording media. The computer readable recording medium may include any data storage device that can store data which can be thereafter read by a computer system or processing device. Examples of the computer readable recording medium include read only memory (ROM), random access memory (RAM), CD-ROM, magnetic tape, floppy disk, optical data storage devices. Moreover, programmers in the art to which the embodiments pertain can easily construct functional programs, codes and code snippet.
