18、ublic and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of Moving Pictures Expert Group (MPEG)-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters ma
19、rket-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. STD-ETSI TS 301 192-ENGL 1997 3400855 0255733 5bb W 6 TS 1 O1 192 Vi .2.1 (1 997-1 2) 1 Scope The present document is designed to be used in conjunction with EN 300 468 21
20、 and ETR 211 4. The DVB System provides a means of delivering MPEG-2 Transport Streams (TS) via a variety of transmission media. These TSs have traditionally been oriented to containing MPEG-2 Video and Audio. Data broadcasting is seen as an important extension of the MPEG-2 based DVB transmission s
21、tandards. Examples for data broadcasting are the download of software over satellite, cable or terrestrial links, the delivery of internet services over broadcast channels (internet Protocol (IP) tunnelling), interactive TV etc. Four different application areas with different requirements for the da
22、ta transport have been identified. For each application area a data broadcasting profile is specified in the present document. The following is a short description of the application areas and the profiles. Data piping - The data broadcast specification profile for data pipes supports data broadcast
23、 services that require a simple, asynchronous, end-to-end delivery of data through DVB compliant broadcast networks. Data broadcast according to the data pipe specification is carried directly in the payloads of MPEG-2 TS packets (see ISO/IEC 13818-1 i). Data streaming - The data broadcast specifica
24、tion profile for data streaming supports data broadcast services that require a streaming-oriented, end-to-end delivery of data in either an asynchronous, synchronous or synchronized way through DVB compliant broadcast networks. Data broadcast according to the data streaming specification is carried
25、 in Program Elementary Stream (PES) packets which are defined in MPEG-2 Systems (see ISO/EC 13818-1 i). - Asynchronous data streaming is defined as the streaming of only data without any timing requirements (e.g. RS-232 data). Synchronous data streaming is defined as the streaming of data with timin
26、g requirements in the sense that the data and clock can be regenerated at the receiver into a synchronous data stream (e.g. El, Tl). Synchronized data streaming is defined as the streaming of data with timing requirements in the sense that the data within the stream can be played back in synchroniza
27、tion with other kinds of data streams (e.g. audio, video). - Multiprotocol encapsulation - The data broadcast specification profile for multiprotocol encapsulation supports data broadcast services that require the transmission of datagrams of communication protocols via DVB compliant broadcast netwo
28、rks. The transmission of datagrams according to the multiprotocol encapsulation specification is done by encapsulating the datagrams in DSM-CC data carousel specification (DSM-CC) sections (see ISO/iEC 13818-6 5), which are compliant with the MPEG-2 private section format (see ISO/iEC 13818-1 i). Da
29、ta carousels - The data broadcast specification for data carousels supports data broadcast services that require the periodic transmission of data modules through DVB compliant broadcast networks. The modules are of known sizes and may be updated, added to, or removed from the data carousel in time.
30、 Modules can be clustered into a group of modules if required by the service. Likewise, groups can in turn be clustered into SuperGroups. Data broadcast according to the data carousel specification is transmitted in a DSM-CC data carousel which is defined in MPEG-2 DSMCC (see ISOIIEC 138186 BI). Thi
31、s specification defines additional structures and descriptors to be used in DVB compliant networks. The method is such that no explicit references are made to Packet IDentifier (PD) and timing parameters enabling preparation of the content off-line. - Object carousels - The object carousel specifica
32、tion has been added in order to support data broadcast services that require the periodic broadcasting of DSM-CC User-User (U-U) Objects through DVB compliant broadcast networks, specifically as defined by DVB SIS (see ETS 300 802 lo).
