Description

METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNALING INFORMATION FOR RECEPTION OF BROADCAST SERVICES IN A DIGITAL BROADCASTING SYSTEM Field of Invention The present invention relates generally to a digital broadcasting system, and more particularly, to a method and apparatus for transmitting and receiving signaling information for reception of broadcast services in a digital broadcasting system. Background Art An example of a second-generation mobile broadcast standard is Next Generation Handheld (NGH), which is established by Digital Video Broadcasting (DVB), a European digital broadcast standards organization. DVB-NGH utilizes a Moving Picture Experts Group 2 (MPEG2) Transport Stream (TS)-based profile for ensuring the maximum capability with terrestrial broadcasting networks, and an Internet Protocol (IP) profile for interoperability with an IP network, which is expected to be used as a backbone network of next-generation broadcasting networks. The MPEG2 TS profile provides broadcast service data, information about a transmission network in which the broadcast service data is transmitted, and physical layer information of the transmission network, using Program Specific Information/Service Information (PSI/SI) technology used in MPEG2 TS standards and DVB standards. However, the IP profile, because it does not use MPEG2 TS-based PSI/SI, should provide broadcast service data, information about a 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 method. Summary of Invention Accordingly, an embodiment of the present invention provides a method and apparatus for efficiently transmitting and receiving signaling information for reception of broadcast services in a digital broadcasting system. Another embodiment of the present invention provides a method and apparatus for efficiently transmitting signaling information using an IP-based network. Another embodiment of the present invention provides a method and apparatus for transmitting and receiving signaling information for reception of broadcast services using a Service Guide Delivery Descriptor (SGDD) in a digital broadcasting system.

In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness when their inclusion might obscure the subject matter of the present invention. Although embodiments of the present invention will be described below with reference to DVB-NGH and Open Mobi le Al l iance Mobi le Broadcast ing Service (OMA BCAST) technology, which is an application layer standard for mobile broadcast, among broadcast technologies to which the present invention is applicable, by way of example, the scope of the present invention is not limited thereto. FIG. 1 illustrates a broadcast service guide for receiving broadcast services in a mobile broadcasting system, according to an embodiment of the present invention. Specifically, FIG. 1 illustrates a data model of a broadcast service guide that for providing broadcast services to terminals. Referring toFIG. 1, the broadcast service guide includes fragments that have different purposes, where the fragments are classified into four groups according to their capabilities. Specifically, the broadcast service guide includes an administrative group 100 for providing parent (upper-rank) configuration information of the entire broadcast service guide, a provisioning group 110 for providing rate (or fee) information for receiving broadcast services, a core group 120 for providing core information of the broadcast service guide, such as broadcast services, content, and broadcasting service schedule, and an access group 130 for providing access information for accessing broadcast services or content. In FIG. 1, solid lines connecting fragments refer to cross-references between the fragments. The administrative group 100, which is a group providing basic information with which a terminal receives the broadcast service guide, includes a Service Guide Delivery Descriptor (SGDD) 101. The SGDD 101 provides information about a channel on which a plurality of broadcast service guide' fragments may be received, scheduling information, and update information, to a terminal, such that the terminal may timely receive the broadcast service guide. The provisioning group 110 is a group for providing rate information for reception of broadcast services and includes a purchase item fragment 111, a purchase data fragment 112, and a purchase channel fragment 113. The purchase item fragment 111 provides rate information for bundles of broadcast services, content, and time, to a user, which help the user subscribe to or purchase desired purchase items. The purchase data fragment 112 provides information about the ways the user can pay the fee. The purchase channel fragment 113 provides access information for subscribing to or purchasing broadcast services.

The core group 120 provides information about broadcast services themselves. Specifically, the core group 120 includes a service fragment 121, a schedule fragment 122, and a content fragment 123. The service fragment 121, which is a core of the broadcast service guide or a parent (or top) collection of content included in broadcast services, provides information about synopses, genres, and service areas of broadcast services. The schedule fragment 122 provides time information for each content included in the broadcast services, e.g., streaming and downloading. The content fragment 123 provides information about detailed descriptions, target user groups, service areas, and genres for the broadcast content. The access group 130 includes an access fragment 131 and a session description fragment 132. The access group 130 provides broadcast service access information indicating the ways the user can receive broadcast services in the core group 120, and detailed information about the session throughwhich content in the broadcast services is delivered. Using this information, the terminal accesses the broadcast services. The access fragment 131 provides access-related information for enabling access to broadcast services, and provides delivery methods and session information for a related access session. The session description fragment 132 may be included in the access fragment 131, and may provide location information in the form of a Uniform Resource Identifier (URI), in order for the terminal may check the session description information. The session description fragment 132 provides address information and codec information for the content existing in the session. The broadcast service guide further includes a preview data fragment 124 and an interactive data fragment 125 in addition to the four groups. The preview data fragment 124 provides previews and icons for broadcast services and content, and the interactive data fragment 125 provides information about interactive broadcast services in which the user may participate. FIG. 2 illustrates an NGH protocol for DVB-NGH according to an embodiment of the present invention. Specifically, signaling information of an IP profile is transmitted and received in an upper layer of an Internet protocol (IP) layer 205. Referring to FIG. 2, a DVB-NGH physical layer 201 transfers a bitstream using an appropriate modulation scheme, and transfers Layer-1 (Li) signaling 202. TheLi signaling 202 provides information used in a physical layer, such as information that a terminal uses for its access to or disconnection from DVB-NGH. Reference numerals 203 and 204 represent upper layers of the physical layer, wherein data received from their upper layer is converted into BaseBand (BB) frames through an encapsulation process. Broadcast service data 206 (e.g., the broadcast service guide described in connection with FIG. 1), Upper Layer Information (ULI) 207 including network information from a data layer to an application layer of a transmission network where the broadcast service data is transmitted, and Neighboring Multiplexes Information (NMI) 208 including information about a transmission network(s) neighboring the transmission network are included in anupper layer of the IP layer 205. The ULI 207 and NMI 208 include signaling information of an IPprofile. The signaling informationof an IPprofile is used to receive information existing in lower layers of the IP layer 205. The ULI 207 includes Robust Header Compression (RoHC) information for compressing IP headers of all IP streams for their transmission and reception, information for mapping broadcast service components to Physical Layer Pipes (PLPs), and physical parameters of PLPs associated with broadcast services. For example, the ULI 207 may include syntaxes as given in Table 1 below. [Table 1] Syntax Number of bits Identifier service association section() { sectionlength 32 uimsbf numberofservices 8 uimsbf for (i=0; i<N; i++){ number of components 8 bslbf for (j=O; j<Nl; j++) { URLlength 8 bslbf for (k O; k<N2; k++) { URLbyte or IP address + port number 8 uimsbf I context id or 16 uimsbf contextprofile 8 uimsbf static infolength 8 uimsbf for (1=0; 1<N3; 1++) { static chain byte() 8 bslbf } Anchor flag 1 uimsbf PLP id 8 uimsbf MIMDMode 2 uimsbf RFU 5 uimsbf } TINT APLPF 16 uimsbf BS APLPF 24 uimsbf } cRO-byte 32 uimsbf } RoHC information included in the ULI 207 includes a Uniform Resource Locator (URL) length field, a 'ULR-byte or IP address + port number' field, a Context Identification (CID) field, a context profile field, a static informat ion length (staticinfolength) field, and a static chain byte field. The information for mapping broadcast service components to PLPs includes an anchor flag field, a PLP id field, a Multiple Input Multiple Output (MIMO) mode field, and a Reserved for Future Use (RFU) field. The physical parameters of PLPs associated with broadcast services include a TINTAPLPF field and a BSAPLPF field. Each field in Table 1 may be defined as in Table 2 below. [Table 2] Fields Definitions section length A field indicating a length of a section number of A field indicating the number of broadcast services services delivered on the current channel number of A field indicating thenumber of components delivered components through the broadcast service in a broadcast service loop URL length A field indicating a length of a URLbyte or IP address + port number field indicating each component URL-byte or IP A text byte field (IP address + port number) of a address + port number URLbyte value indicating each component, or an IP address indicating an IP channel on which each component is transmitted, and a port number. context id A field indicating a CID of a compressed IP stream context profile A field indicating a context profile of a compressed IP stream static info A field indicating a length of a static chain byte length sequence static chain A field indicating a byte sequence which is static byte information of a compressed IP stream Anchor Flag A field indicating that PLP is an anchor of all PLPs associated with a given broadcast service PLP ID A field indicating a PLP ID to which the component is delivered MIMOMODE A field indicating use of Single Input Single Output (SIS0)/MIMO structure T_INTAPLPF A field indicating a time (in milliseconds or Orthogonal Frequency Divis ion Mul t iplexing (OFDM) symbols) between two consecutive frames of all broadcast service-related PLPs BS_APLPF A f ield indicating the maximum buffer size (e.g., the maximum size of allocated PLP frames) in OFDM cells CRC byte A field indicating a Cyclic Redundancy Check (CRC) byte of a related session 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 l and 15, and the large CID has one or two octets between 1 and 16383. A size of the CID is determined by the following rules: - If a CID value starts with '1110' : a small CID is used for RoHC information, a context size is 1 octet, and a CID has 4 bits; - If aCIDvalue starts with '0' : a largeCID is used for RoHC information, a context size is 1 octet, and a CID has 7 bits; and - If a CID value starts with '10' : a large CID is used for RoHC information, a context size is 2 octets, and a CID has 14 bits.

A range of protocols used to compress an IP stream is notified for RoHC information in the context profile field among the fields inTable 2. A static chain byte field is used to initialize an IP stream compressed based on RoHC information, and the size and structure of the static chain byte field depend on the context profile. Based on the TINTAPLPF in Table 2, the receiver determines whether it canprocess previously allocated PLP frames, for the time, andmay calculate a buffer space for processing the next frame of the associated PLPs. The NMI 208 includes network information for a cell where a terminal receives broadcast services and its adjacent cells, and physical layer information for enabling fast reception of broadcast services. For example, the NMI 208 includes syntaxes as shown in Table 3 below. [Table 3] Syntax Number of Identifier bits mux information section() { NGHsystem-id 16 uimsbf cellid 16 uimsbf numberRF 3 uimsbf for (i=0; i<numberRF; i++) { RFid 3 uimsbf bandwidth 4 uimsbf transmissionmode 3 uimsbf guard-interval 4 uimsbf commonclockreference id 4 uimsbf inbandflag 1 uimsbf if (inbandflag){ nghslotlength 12 uimsbf ngh-slot interval 24 uimsbf } } number ofLNC 3 uimsbf for (i=0; i<number ofLNC; RF main; 3 uimsbf nofPLP; 8 uimsbf for (j=O; j<nofPLP; j++){ PLP-id; 8 uimsbf } } } Each field in Table 3 may be defined as in Table 4 below.

Referring to FIG. 3, a signaling information generator 310 generates a ULI 207 including network information from a data layer to an application layer of a transmission network, and an NMI 208 including information about a neighboring transmission network(s). That is, the signaling information generator 310 generates the ULI 207 including RoHC information for all IP streams, information for mapping broadcast service components to PLPs, and physical parameters of PLPs associated with broadcast services shown in Table 1, and generates the NMI 208 including network information for a cell where the terminal receives broadcast services and its adjacent cells, and physical layer information for fast reception of broadcast services, as shown in Table 3. An SGDD generator 330 generates an SGDD including the ULI 207 and NMI 208, and an SGDD transmitter 350 transmits the generated SGDD to a receiving apparatus. Although the signaling information generator 310, the SGDD generator 330 and the SGDD transmitter 350 are implemented in separate units in FIG. 3, it will be understood by those of ordinary skill in the art that they may be implemented in a single unit. FIG. 4 illustrates an apparatus for receiving signaling information of an IP profile according to an embodiment of the present invention. Referring to FIG. 4, an SGDD receiver 410 receives an SGDD transmitted from a transmitting apparatus and forwards it to an SGDD decomposer 430. The SGDD decomposer 430 decomposes the ULI 207 and NMI 208 including signaling information of an IP profile from the received SGDD, and delivers the ULI 207 and NMI 208 to a signaling information analyzer 450. 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 the transmission network, which is included in the ULI 207, and checks information about a neighboring transmission network, which is included in the NMI 208. That is, the signaling information analyzer 450 checks RoHC information for all IP streams, information for mapping service components to PLPs, and physical parameters of PLPs associated with broadcast services, all of which are included in the ULI 207, and checks network information for a cell where the terminal receives broadcast services and its adjacent cells, and physical layer information for enabling fast reception of broadcast services, both of which are included in the NMI 208. Although the SGDD receiver 410, the SGDD decomposer 430, and the signaling information analyzer 450 are implemented in separate units in FIG. 4, it will be understood by those of ordinary skill in the art that they may be implemented in a single unit. Further, the SGDD decomposer 430 and the signaling information analyzer 450 may be implemented as a single controller. FIG. 5 is a flowchart illustrating a process of transmitting signaling information of an IP profile according to an embodiment of the present invent i on. Referring to FIG. 5, in step 510, the signaling information generator 310 generates a ULI 207 including RoHC information for all IP streams, information for mapping broadcast service components to PLPs, and physical parameters of PLPs associated with broadcast services, as shown in Table 1 above. In step 530, the signaling information generator 310 generates a NMI 208 including network information for a cell where the terminal receives broadcast services and its adjacent cells, and physical layer information for enabling fast reception of broadcast services, as shown in Table 3 above. In step 550, the SGDD generator 330 generates an SGDD including the gener ated UL I 207 and NMI 208. In step 570, the SGDD transmitter 350 transmits the generated SGDD to a receiving apparatus. Alternatively, the ULI generation step (step 510) and the NMI generation step (step 530) are interchangeable. FIG. 6 is a flowchart illustrating a process of receiving signaling information of an IP profile according to an embodiment of the present invent ion. Referring to FIG. 6, the SGDD receiver 410 receives an SGDD transmitted from a transmitting apparatus in step 610, and the SGDD decomposer 430 decomposes an ULI 207 and an NMI 208 including signaling information of an IP profile from the received SGDD in step 630. In step 650, the signaling information analyzer 450 analyzes the ULI 207 to check for RoHC information for all IP streams, information for mapping service components to PLPs, and physical parameters of PLPs associated with broadcast services, and analyzes the NMI 208 to check for network information for a cell where the terminal receives broadcast services and its adjacent cells, and physical layer information for enabling fast reception of broadcast services. In summary, in accordance with an embodiment of the present invention, signaling information of an IP profile to a receiving apparatus (e.g., terminal) in an SGDD in DVB-NGH is provided, thereby reducing the delay time in which the receiving apparatus gets the signaling information.
