Digital Video Broadcasting (DVB); Interaction channel for Digital Terrestrial Television (RCT) incorporating Multiple Access OFDM

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.
