The present document provides implementation guidelines for the use of audio-visual coding in satellite, cable and
terrestrial broadcasting distribution systems that utilize MPEG-2 Systems. Both Standard Definition Television (SDTV)
and High Definition Television (HDTV) are covered. MPEG-2, H.264/AVC and VC-1 video coding systems are
covered. MPEG-1/MPEG-2 Layer II, Dolby AC-3, Enhanced AC-3, DTS, MPEG-4 HE AAC and MPEG-4 HE AAC
v2 audio coding systems are covered. Guidelines for devices equipped with a digital interface intended for digital VCR
applications are also given in the present document. It does not cover applications such as contribution services which
are likely to be the subject of subsequent "Guidelines" documents.
The rules of operation for the encoders are features and constraints which the encoding system should adhere to in order
to ensure that the transmissions can be correctly decoded. These constraints may be mandatory, recommended or
optional.
