Foreword This Te

36、chnical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). The present document is complementary to TR 10

37、1 154 14. TR 101 154 14 provides MPEG Implementation Guidelines for the use of Video and Audio Coding in Broadcasting Applications based on the MPEG-2 Transport Stream. The present document is a companion document which follows the same format and provides Implementation Guidelines for the use of Vi

38、deo and Audio Coding in Transport Stream based contribution applications (such as Satellite News Gathering) and primary distribution applications (such as delivery of network programming to local broadcasting stations). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the draf

39、ting 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 Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional as

40、sociation of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. Europea

Its aim is to establish the framework for the intr

42、oduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. Introduction The pr

43、esent document presents guidelines covering contribution/primary distribution coding and decoding using the MPEG-2 system layer, video coding and audio coding as defined in ISO/IEC 13818-1 1, ISO/IEC 13818-2 2, ISO/IEC 11172-3 9 and ISO/IEC 13818-3 3 respectively.

44、5) 9 Contribution applications are those where the signal from the MPEG decoder is not supplied directly to the ultimate viewer, and where some form of processing (e.g. in a vision mixer) may be expected before the signal reaches the ultimate viewer. Satellite News Gathering (SNG) is a typical examp

45、le of a contribution application. Primary Distribution applications are those where a completed programme is delivered to a site, such as a local broadcast station, that will then encode the signal for delivery to the final consumer. Some additional processing of the signal may occur. A higher quali

46、ty of video and audio signal may be required for contribution and primary distribution applications than for the secondary distribution/emission applications. A secondary distribution/emission application is one where the signal from the MPEG decoder is expected to be either supplied directly to the

47、 ultimate viewer or else to the ultimate viewer via some intermediate stage that does not involve video or audio processing. Guidelines for secondary distribution/emission applications are provided by TR 101 154 14. The guidelines presented in the present document for the Contribution/Primary Distri

48、bution Integrated Receiver-Decoder (herewith designated “Contribution IRD“) are intended to represent a minimum functionality that all Contribution IRDs of a particular class are required to either meet or exceed. Contribution IRDs are classified in two dimensions as: “25 Hz“ or “30 Hz“, depending o

49、n whether the nominal video frame rates based on 25 Hz or 30 000/1 001 Hz (approximately 29,97 Hz) are supported. It is expected that 25 Hz Contribution IRDs will be used in those countries where the existing analogue TV transmissions use 25 Hz frame rate and 30 Hz Contribution IRDs will be used in countries where the analogue TV transmissions use 30 000/1 001 Hz frame rate. There are also likely to be “dual-standard“ Contribution IRDs which have the capabilities of both 25 Hz and 30 Hz Contribution IRDs. “SDTV“ or “HDTV“, depending on whether or not t
