| Requirements and technical specifications of a cable TV hybrid set-top box compatible with terrestrial and satellite TV transport |
 |
Recommendation ITU-T J.298 describes the requirements and technical specifications of a cable TV hybrid set-top box compatible with terrestrial and satellite TV transport. The main purpose of the Recommendation is to specify minimum and basic requirements for a hybrid set-top box (STB), which meets the requirements of developing countries and regions. The hybrid set-top box has full functionalities for traditional cable broadcasting services based on Recommendation ITU-T J.83, at the same time, satellite or a terrestrial broadcast receiving functions will also be implemented so that the STB is able to receive satellite or terrestrial broadcasting services. The basic functionalities for IP-based interactive video services are also required so that the STB be able to support the latest Internet protocol (IP) interactive services together with legacy cable and satellite/terrestrial services. |
