38、. Introduction The present document presents guidelines covering contribution/primary distribution coding and decoding using the MPEG-2 system layer, video coding and audio coding as defiied in ISO/IEC 13818-1 i, ISO/IEC 13818-2 2, ISO/IEC 11172-3 lo and ISO/IEC 13818-3 3 respectively. ETSI 8 ETSI T

39、R 102 154V1.1.1 (2001-04) 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 (SN

40、G) is a typical example 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

41、occur. A higher quality 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 sup

42、plied directly to the 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 1 O 1 154 171. The guidelines presented in the present document for the Con

43、tribution/Primary Distribution 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“

44、 or “30 Hz“, depending on whether the nominal video frame rates based on 25 Hz or 30 OOO/lOOlHz (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

45、 IRDs will be used in countries where the analogue TV transmissions use 30 000/1001 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. 0 “SDTV“ or “HDTV“, depending on whether or not they are limited to

46、decoding pictures of conventional TV resolution. The capabilities of an SDTV Contribution IRD are a sub-set of those of an HDTV Contribution IRD. To give a complete definition of a Contribution IRD, both dimensions need to be specified, e.g. 25 Hz SDTV Contribution IRD. Where a feature described in

47、the present document is mandatory, the word “shall“ is used and the text is in italic; all other features are optional. The functionality is specified in the form of constraints on MPEG-2 systems, video and audio which the Contribution IRDs are required to decode correctly. The specification of thes

48、e baseline features in no way prohibits manufacturers of Contribution IRDs from including additional features, and should not be interpreted as stipulating any form of upper limit to the performance. The guidelines do not cover features, such as the Contribution IRDs up-sampling filter, which affect

49、 the quality of the displayed picture rather than whether the Contribution IRD is able to decode pictures at all. Such issues are left to the marketplace. The guidelines presented for Contribution IRDs observe the following principles: a Contribution IRD should be capable of decoding all corresponding contribution bitstreams specified in the mandatory clauses of the present document. For example, a 25 Hz SDTV Contribution IRD should be capable of decoding a 25 Hz SDTV contribution bitstream. However, it would not necessarily be capable of decoding any optional
