| Guidelines for the implementation of annex A of Recommendation J.112, "Transmission systems for interactive cable television services" – Example of digital video broadcasting (DVB) interaction channel for cable television distribution |
 |
This Supplement gives guidelines for use of the DVB interaction channel for Cable TV distribution systems (CATV) specification of Annex A/J.112 [2].
Hybrid Fibre Coax (HFC) networks are a sub-class of CATV networks in which the subscribers are divided into groups by using optical transmission technology in the trunk network.
The CATV infrastructures can support the implementation of the RC for interactive services suitable for DVB systems.
CATV can be used to implement interactive services in the DVB environment, providing a bidirectional communication path between the user terminal and the service provider. |
