Description

FIELD OF THE INVENTION

[1] The present invention generally relates to a digital broadcasting system, and more particularly, to a method and apparatus for transmitting and receiving signaling information for receiving broadcast services in a digital broadcasting system.

State of the art

[2] An example of a second generation broadcast standard for mobile devices is the Next Generation Portable Devices (NGH) standard, which is established by Digital Video Broadcasting (DVB), the European Organization for Digital Broadcasting Standards. DVB-NGH uses the Transport Stream (TS) Moving Pictures Expert Group 2 (MPEG2) Profile to provide maximum throughput with terrestrial broadcast networks and the Internet Protocol (IP) profile for interoperability with the IP network, which is expected to should be used as the backbone network of next-generation broadcast networks.

[3] MPEG2 TS profile provides broadcast service data, transmission network information in which broadcast service data is transmitted, and physical layer information of a transmission network using program specific information / service information (PSI / SI) technology used in TS standards MPEG2 and DVB standards. However, the IP profile, since it does not use MPEG2 PSI / SI based on TS, must provide broadcast service data, information about the transmission network in which the broadcast service data is transmitted, and physical layer information (i.e. signaling information) of the transmission network using a separate way.

[20] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific elements, such as detailed configurations and components, are provided only to facilitate a thorough understanding by a person skilled in the art of exemplary embodiments of the present invention. Therefore, one skilled in the art will appreciate that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention as defined in the appended claims. In addition, descriptions of known functions and constructions may be omitted for clarity and brevity, when their presence may complicate the understanding of the subject matter of the present invention.

[21] Although embodiments of the present invention will be described below with reference to DVB-NGH technology and the Broadcast Services for Mobile Devices of the Open Mobile Alliance (OMA BCAST), which is an application layer standard for broadcasting for mobile devices, among broadcast technologies, to which the present invention is applicable, by way of example, however, the scope of the present invention is not limited to such use.

[22] FIG. 1 illustrates a broadcast service guide for receiving broadcast services in a broadcast system for mobile devices according to one embodiment of the present invention. In particular, FIG. 1 shows a data model of a broadcast service guide that is intended to provide broadcast services to terminals.

[23] In FIG. 1, a broadcast service guide includes fragments that have different purposes, the fragments being divided into four groups according to their capabilities. In particular, the broadcast service guide includes an administrative group 100 for providing information about the parent (top rank) leadership configuration of the entire broadcast service, a providing group 110 for providing tariff (or payment) information for receiving broadcast services, a main group 120 for providing the main broadcast service guide information, such as broadcast services, service content and schedule, and access group 130 for providing and Access information for accessing broadcast services or content. 1, solid lines connecting fragments refer to cross-references between fragments.

[24] An administrative group 100, which is a group providing basic information by which a terminal receives a broadcast service guide, includes a Service Guide Delivery Descriptor 101 (SGDD). SGDD 101 provides channel information through which a plurality of broadcast service guide fragments, schedule information, and update information can be received at the terminal, so that the terminal can receive broadcast service guide in a timely manner.

[25] The provisioning group 110 is a group for providing tariff information for receiving broadcast services and includes a fragment 111 with a purchase item, a fragment 112 with purchase data and a fragment 113 with a purchase channel. Fragment 111 with a purchase item provides tariff information for broadcast service packages, content and time to the user, which help the user to subscribe to the desired purchase items or buy them. Fragment 112 with data about the purchase provides information about the ways in which the user can make a payment. Fragment 113 with a purchase channel provides access information for subscribing to broadcast services or about their purchase.

[26] The core group 120 provides information on broadcast services directly. In particular, the main group 120 includes a fragment 121 with a service, a fragment 122 with a schedule, and a fragment 123 with content. The service fragment 121, which is the basis of the broadcast service guide or the parent (or top) collection of content included in the broadcast service, provides information on the brief overviews, genres and service areas of broadcast services. The schedule snippet 122 provides time information for each content included in broadcast services, such as streaming and downloading. Content snippet 123 provides detailed descriptions, target user groups, service areas, and genres for broadcast content.

[27] The access group 130 includes an access fragment 131 and a session description fragment 132. The access group 130 provides information about access to broadcast services, indicating the ways in which a user can receive broadcast services in the main group 120, and detailed information about the session through which the content in the broadcast services is delivered. Using this information, the terminal provides access to broadcast services.

[28] The access fragment 131 provides access-related information to enable access to broadcast services, and provides delivery methods and session information for an access-related session. The session description fragment 132 may be included in the access fragment 131 and may provide location information in the form of a Unified Resource Identifier (URI) so that the terminal can verify the session description information. The session description fragment 132 provides address information and codec information for the content present in the session.

[29] The broadcast service guide further includes a fragment 124 with preview data and a fragment 125 with interactive data in addition to the four groups. Fragment 124 with preview data provides previews and icons for broadcast services and content, and fragment 125 with interactive data provides information about interactive broadcast services in which the user can participate.

[30] Figure 2 illustrates the NGH protocol for DVB-NGH according to one embodiment of the present invention. In particular, IP profile signaling information is transmitted and received at the upper level of the Internet Protocol (IP) layer 205.

[31] In FIG. 2, the physical layer 201 of the DVB-NGH carries the bitstream using a suitable modulation scheme and carries the Layer 1 (L1) signaling 202. The L1 signaling 202 provides information used at the physical level, such as information that the terminal uses to access or disconnect from DVB-NGH on its own. Reference numerals 203 and 204 represent upper layers of the physical layer in which data received from its upper layer is converted to frames of the Main Strip (BB) through an encapsulation process.

[32] Broadcast service data 206 (eg, the broadcast service guide described in conjunction with FIG. 1), High Level Information (ULI) 207 including network information from a data layer to an application layer of a transmission network in which broadcast data is transmitted services, and Neighboring Device Multiplexing Information (NMI) 208, including information about a transmission network (s) adjacent to said transmission network, are included in the upper layer at IP level 205. ULI 207 and NMI 208 include IP profile signaling information. IP profile signaling information is used to receive information existing in the lower layers of IP level 205.

[33] ULI 207 includes Interference Immunity Header Compression (RoHC) information for compressing the IP headers of all IP streams for transmission and reception, information for mapping broadcast service components to Physical Layer Channels (PLPs), and physical parameters of PLP channels, associated with broadcast services. For example, ULI 207 may include the syntax specified in Table 1 below.

[34] Table 1 1

[35] RoHC information included in ULI 207 includes the field “Uniform Resource Locator (URL) length”, the field “URL_byte or IP address + port number” (“byte URL or IP- address + port number ”), the“ Context Identification (CID) ”field, the“ context profile ”field, the static_info_length field and the static chain field byte ′ (byte static chain). Information for mapping broadcast service components to PLP channels includes an anchor flag field, a PLP id field (PLP identifier), a Multiple Input Multiple Output (MIMO) mode field, and Inputs and Multiple Outputs ”), and the field 'Reserved for Future Use (RFU)' (" Reserved for Future Use "). The physical parameters of PLP channels associated with broadcast services include a T_INT_APLPF field and a BS_APLPF field.

[36] Each field in Table 1 can be defined as in Table 2 below.

[37] Table 2

[38] In the CID field in Table 2, a small CID or a large CID is used for RoHC information. The small CID has one octet between 1 and 15, and the large CID has one or two octets between 1 and 16383. The size of the CID is determined by the following rules

[39] - If the CID value starts with '1110': a small CID is used for RoHC information, the context size is 1 octet, and the CID has 4 bits.

[40] - If the CID value starts with '0': a large CID is used for RoHC information, the context size is 1 octet, and the CID has 7 bits.

[41] - If the CID value starts with '10': a large CID is used for RoHC information, the context size is 2 octets, and the CID has 14 bits.

[42] The protocol range used to compress the IP stream is reported for RoHC information in the context profile field among the fields in Table 2. The static chain byte field is used to initialize the IP stream compressed based on RoHC information, and the size and structure of the byte field static chains depend on the context profile.

[43] Based on the T_INT_APLPF in Table 2, the receiver determines whether it is capable of processing previously allocated PLP frames during this time, and whether it can calculate the buffer space to process the next frame of the associated PLP channels.

[44] The NMI 208 includes network information for a cell in which the terminal receives broadcast services and related cells, and physical layer information to enable fast reception of broadcast services. For example, NMI 208 includes syntax such as that shown in Table 3 below.

[52] Although the signaling information generator 310, the SGDD generator 330, and the SGDD transmitter 350 are implemented in separate blocks in FIG. 3, those skilled in the art will understand that they can be implemented in a single block.

[53] FIG. 4 illustrates an apparatus for receiving IP profile signaling information according to one embodiment of the present invention.

[54] In FIG. 4, an SGDD receiver 410 receives an SGDD transmitted from a transmitter and forwards it to an SGDD decomposition unit 430. The SGDD decomposition unit 430 decomposes the ULI 207 and NMI 208, including IP profile signaling information, from the received SGDD, and delivers the ULI 207 and NMI 208 to the signaling information analyzer 450.

[55] By analyzing each of the ULI 207 and NMI 208, the signaling information analyzer 450 checks network information from a data layer to an application layer of a transmission network that is included in ULI 207, and checks information about a neighboring transmission network that is included in NMI 208. Thus thus, the signaling information analyzer 450 checks the RoHC information for all IP streams, information for mapping service components to PLP channels, and physical parameters of the PLP channels associated with broadcast services, all of which are included in ULI 207, and checks the information a network overview for a cell in which the terminal receives broadcast services and adjacent cells, and physical layer information to enable fast reception of broadcast services, both of which are included in the NMI 208.

At step 530, the signaling information generator 310 generates an NMI 208, including network information for the cell in which the terminal receives broadcast services and its adjacent cells, and physical layer information to enable fast reception of broadcast services, as shown in Table 3 above.

[59] At step 550, the SGDD generator 330 generates an SGDD including the generated ULI 207 and NMI 208. At step 570, the SGDD transmitter 350 transmits the generated SGDD to the receiving device.

[60] Alternatively, the ULI generation step (step 510) and the NMI generation step (step 530) are interchangeable.

[61] FIG. 6 is a flowchart depicting a process for receiving IP profile signaling information according to one embodiment of the present invention.

[62] In FIG. 6, the SGDD receiver 410 receives the SGDD transmitted from the transmitter in step 610, and the SGDD decomposition unit 430 decomposes the ULI 207 and NMI 208 including IP profile signaling information from the received SGDD in step 630. In step 650, signaling information analyzer 450 analyzes ULI 207 to check for RoHC information for all IP streams, information for mapping service components to PLP channels, and physical parameters of PLP channels associated with broadcast services, and analyzes NMI 208 to check for information about networks for s, in which the terminal receives broadcast services, and related cells, and physical layer information to enable fast acquisition of broadcast services.
