ITU-R BS.1688 FRENCH-2004 大屏幕数字影像应用的传输接口的基带音响系统和音频源编码

The ITU Radiocommunication Assembly considering: a) that Recommendation ITU-R BT.1662–General reference chain and management of post-processing headroom for programme essence in large screen digital imagery applications, specifies a general reference chain for typical large screen digital imagery (LSDI) applications, and its principles equally apply to image essence and to sound essence; b) that an important feature of the general reference chain is the identification of the main functional blocks in a generic chain, and of the interfaces between them; c) that, for the delivery of LSDI applications, it is necessary to identify the reference baseband sound system and to also identify the source-coding 1 method used for the audio programme delivery: at the interface between the LSDI programme distribution master 2 and the delivery channel; at the interface between the delivery channel and the audio system in the presentation venue; d) that Recommendation ITU-R BT.1666 – User requirements for large screen digital imagery applications intended for presentation in a theatrical environment, identifies the subjective overall picture and sound quality to be provided at the highest performance level of the family of applications intended for LSDI presentation in a theatrical environment; e) that Recommendation ITU-R BS.775 – Multichannel stereophonic sound system with and without accompanying picture, specifies a 5-1 reference sound system with five channels 3 plus an optional low-frequency effects channel, as the highest level in a hierarchy of multichannel sound systems that range from 1/0 (monophonic) up to 3/2; f) that the 5-1 reference sound system specified in Recommendation ITU-R BS.775 can provide the sound quality identified in Recommendation ITU-R BT.1666; g) that in some cases it is important to optimize the sound programme (e.g. 2 channel stereo, 2-channel matrix surround, or 5-1 channels) for presentation in a specific target venue (e.g. small venue or large venue); h) that for the delivery of LSDI content over bandwidth constrained channels (e.g. satellite), a reduction in audio bit rate will reduce transmission cost; j) that ITU-R has performed subjective audio tests, has evaluated subjective audio tests conducted by other organizations and has documented, in Recommendation ITU-R BS.1548–User requirements for audio coding systems for digital broadcasting, the quality that can be provided by various source-coding algorithms at certain bit rates; k) that LSDI can benefit from the use of equipment and systems that have been developed to support digital television; l) that digital audio as practiced in broadcast and other professional areas employs a sampling rate of 48 kHz without application of frequency dependent emphasis.
