scope:

This ETS defines the D2-HDMAC/packet system for High Definition Television (HDTV) broadcasting. It covers the baseband structure, multiplexing and modulation for the High Definition Multiplexed Analogue Components (HDMAC) vision signal and the accompanying digital services.

As a member of the MAC/packet family this system incorporates the following features:

- time division multiplexing;

- HDMAC picture coding;

- packet multiplexing for sound and data;

- digital high and medium quality sound coding;

- service identification;

- conditional access with video, sound and data scrambling.

Field of application

This ETS sis applicable to:

- satellite transmission with FM modulation;

- cable distribution with AM/VSB modulation;

- possible future applications such as

- terrestrial broadcasting;

-point to point transmissions;

- video cassettes, laser vision discs etc.
