Foreword This Technical Report (TR) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de

31、 Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI)(Broadcast). The original ETSI TR 101 154 was based on the DVB document A001 and it covered only the 25 Hz SDTV Baseline IRD. The first revision of ETSI TR 101 154 extended the scope to encompass

32、both the 25 Hz SDTV Baseline IRD and the 25 Hz SDTV IRD with a digital interface intended for connection to a bitstream storage device such as a digital VCR. The second revision covered both the Baseline IRD and the IRD with digital interface for 25 Hz SDTV, 25 Hz HDTV, 30 Hz SDTV and 30 Hz HDTV. Th

33、is third revision adds optional support for the video Active Format Description (Annex B), AC-3 audio (Annex C) and Ancillary Data for MPEG audio (Annex D). The revisions to the TR have been developed in a largely backwards compatible manner, i.e. no changes to the mandatory functionality of a previ

34、ously defined IRD have been made between one edition of the TR and the next. 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

35、in the Memorandum of 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, programme-maki

36、ng and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva.

37、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 around the world, DVB fo

38、sters market-led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry. Introduction The present document presents guidelines covering coding and decoding using the MPEG-2 system layer, video coding and audio coding as defined in ISO/I

39、EC 13818-1 i, ISO/IEC 13818-2 2, ISO/IEC 11172-3 lo and ISO/IEC 13818-3 3 respectively. ETSI 8 ETSI TR 1 O1 154 V1.4.1 (2000-07) The guidelines presented in the present document for the Integrated Receiver-Decoder (IRD) are intended to represent a minimum functionality that all IRDs of a particular

40、class are required to either meet or exceed. It is necessary to specify the minimum IRD functionality for basic parameters, if broadcasters are not to be prevented from ever using certain features. For example, if a significant population of IRDs were produced that supported only the Simple Profile,

41、 broadcasters would never be able to transmit Main Profile bit-streams. IRDs are classified in three dimensions as: “25 Hz“ or “30 Hz“, depending on 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 IRDs will be

42、used in those countries where the existing analogue TV transmissions use 25 Hz frame rate and 30 Hz 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 IRDs which have the capabilities of both 25 Hz and 30 Hz I

43、RDs. “SDTV“ or “HDTV“, depending on whether or not they are limited to decoding pictures of conventional TV resolution. The capabilities of an SDTV IRD are a sub-set of those of an HDTV IRD. “with digital interface“ or “Baseline“, depending on whether or not they are intended for use with a digital

44、bitstream storage device such as a digital VCR. The capabilities of a Baseline IRD are a sub-set of those of an IRD with digital interface. To give a complete definition of an IRD, all three dimensions need to be specified, e.g. 25 Hz SDTV Baseline IRD. It should be noted that in DVB systems the sou

45、rce picture format, encoded picture format and display picture format do not need to be identical. For example, HDTV source material may be broadcast as an SDTV bitstream after down- conversion to SDTV resolution and encoding within the constraints of Main Profile at Main Level. The IRD receiving th

46、e bitstream may then up-convert the decoded picture for display at HDTV resolution. With suitable down-conversion and up-conversion, the quality of the resultant HDTV picture may be close to that of the original HDTV source. Another notable feature of the DVB system is that a single Transport Stream

47、 may contain programme material intended for more than one type of IRD. A typical example of this is likely to be the simulcasting of SDTV and HDTV video material. In this case an SDTV IRD will decode and display SDTV pictures whilst an HDTV IRD will decode and display HDTV pictures from the same Tr

48、ansport Stream. Where a feature described in 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 IRDs are required to decode corr

49、ectly. The specification of these baseline features in no way prohibits IRD manufacturers 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 IRDs up-sampling filter, which affect the quality of the displayed picture rather than whether the IRD is able to decode pictures at all. Such issues are left to the marketplace. The guidelines presented for IRDs observe the following principles: wherever practical, IRDs should be designed to allow for fut
