Summary

With the increasing availability of sophisticated mobile devices that include broadband Internet access services, cable operators, broadcasters and consumer electronics manufacturers have started taking advantage of this trend by providing connected devices that work as companion devices to enhance the experience of watching television (TV). This technology creates several opportunities for players in all segments involved in delivering enriched and customized content and user experiences.

The integration of these companion mobile devices, also known as second screens with TV and cable set top box (STB) platforms, support several scenarios based on content sharing, synchronization, user interaction and customized presentations. This integration also offers opportunities for the inclusion of intuitive and convenient user interfaces and additional areas for the presentation of information.

Recommendation ITU-T J.230 defines high level requirements for the cable STB and mobile platforms involved in these scenarios. This Recommendation also describes some useful application cases to illustrate the ideas behind the requirements.
