Summary

Recommendation ITU-T Y.1903 describes detailed functional requirements of mobile IPTV, which is an application of IPTV (Recommendation ITU-T Y.1901). It applies to where the IPTV terminal device is connected to the IPTV service provider via an IPTV-enabled mobile network to provide the IPTV services irrespective of changes of the location or technical environment. This Recommendation focuses on the requirements for networking aspects of an IPTV terminal device to the IPTV service provider. This Recommendation does not address the common functional requirements of an IPTV service, which are covered by Recommendation ITU-T Y.1901, but provides the requirements specific to mobile IPTV services only. Thus, these functional requirements are used to develop the detailed specifications of the IPTV functional components which are defined in Recommendation ITU-T Y.1910 for support of mobile IPTV.
