ITU-T J.112 Annex A (03/2001)

Digital Video Broadcasting: DVB interaction channel for Cable TV (CATV) distribution systems

This annex is the baseline specification for the provision of the interaction channel for CATV networks.It is not intended to specify a return channel solution associated to each broadcast system because the interoperability of different delivery media to transport the return channel is desirable.The solutions provided in this annex are a part of a wider set of alternatives to implement interactive services for Digital Video Broadcasting (DVB) systems.
