scope:
The present document is the baseline specification for the provision of the interaction channel for digital terrestrial television distribution system, DVB-T defined in the EN 300 744 standard [1].
The present document:
• gives a general description of the baseline system for interactive digital terrestrial TV;
• specifies the channel coding/modulation; specifies the medium access control protocol;
• provides guidelines on the radio frequency spectrum management.
The purpose of the MAC section is to redefine a set of MAC messages based on the DVB-RCCL MAC message set, adapted to suit the specific characteristics of the physical layer of the DVB-RCT specification.
The solution provided in the present document for return channels through terrestrial broadcast systems is part of a wider set of alternatives for implementing interactive services for DVB systems.
