Combined digital video broadcast receiver and cellular receiver

摘要

A mobile terminal has a DVB-T receiver 202 for receiving digital video broadcast signals and a cellular transceiver 206 for receiving signals containing service information relating to the digital video broadcast signals. Service information comprising programme scheduling information, channel frequency allocation etc. generated by the broadcaster is sent to a profiler 262 which contains details of user preferences and interests. When a video clip of interest to a user is available for broadcast it is scheduled into the DVB-T multiplex signal and a service anouncement is sent via the cellular network. The service anouncement allows the DVB-T receiver to be powered up and configured in time to receive the broadcast video clip. The service anouncement may be in the form of SI (service information) data or a special short message service (SMS). In this way the DVB-T receiver can be powered down when not required thus saving power consumption. If only a small number of users wish to see the video clip it may be sent via the cellular network.
