13、European Telecommunications Standards Ins titute (ETSI). NOTE The EBU/ETSi JTC Broadcast was established in 1990 to Co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of
14、Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the Co-ordination of its members activities in the technical legal, programmemaking and programme-exchan

16、mber 1993, the DVB Project is a market-led consortium of public and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries aroun
17、d the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry.

A testdata table may be made of several testdata sections. Different testdata tables (for differen
24、t applications) are specified by their table-id and table-idextension values. One testdata table shall have only one priority level, so only complete tables may be replaced or removed. The values for structure elements “table-id and “descriptor-tag“ may be user defined as specified in lSO/i.EC 13818
25、-1 Li. In the PSI PMT table, the use of a specific descriptor would allow to precise if, for a given elementary stream, support for all currently identified application areas; the provision should be made for user defined solutions to meet the private needs of network operators; simplification of th
26、e test data inserter and test data removal equipment; prioritization of test data to allow end-to-end communication across a network or the re-use of test data capacity within a network as appropriate to the application. The prioritization of test data packets shall allow their transmission within a
27、 network or across network operator borders. - - - - STD-ETSI TR 101 291-ENGL 1998 m 3400855 031b243 055 I Syntax testdata-section() 9 TR 1 O1 291 V1.l.l (1 998-06) No. of bits Mnemonic 5 table-id priority-level Syntax of PID Ox001 D applications 6 uimsbf 2 uimsbf All table-ids and descriptor-tags d
