用于卫星新闻采集和室外广播的高清电视的数字传输

Digital transmission of high-definition television for satellite news gathering and outside broadcasting

ITU-R SNG.1561 FRENCH-2002 发布历史

The ITU Radiocommunication Assembly considering that in point-to-point video transmission via satellite, quality of service objectives are fixed on the basis of large sized transmitting and receiving station antennas; that the introduction of highly portable transmitting stations is essential particularly for news gathering operations and can provide a satisfactory technical solution; that the special characteristics needed for portable and transportable stations and the reduced link availability characteristics of highly portable stations may necessitate acceptance of reduced transmission performance objectives; that it may be necessary to provide, on the same satellite bearer, the auxiliary signals required for the operation of portable and transportable transmitting stations but that these auxiliary signals should not have a perceptible effect on the transmission quality of the television signals; that throughout the world, where news events take place, standardized and uniform technical and operating procedures should be established to ensure prompt activation of satellite news gathering (SNG) and outside broadcasting services; that to facilitate the international coverage of news, it is necessary to adopt uniform operating parameters for high-definition television (HDTV) digital SNG, to ensure interoperability between equipment from different manufactures.
