The ITU Radiocommunication Assembly,
considering
a) 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;
b) that the introduction of highly portable transmitting stations is essential particularly for
news gathering operations and can provide a satisfactory technical solution;
c) 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;
d) 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;
e) 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;
f) 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.
