Mobile terminal having functions of program reception through broadcasting and through network communication, and program reception controlling method

A mobile terminal is provide for achieving continuous program viewing / listening by appropriately switching between program reception through broadcasting and program reception through communication with a broadcast receiving function and a communication function working cooperatively. A receiver (11) receives a program broadcasted from a broadcasting station (11). A reception state monitoring section (23) monitors a state of receiving the broadcast program in the receiver (21). If the reception state is in a satisfactory state, the broadcast program is reproduced by the reproducing section (12). Upon determination by the reception state monitoring section (23) that the reception state has been deteriorated, a program information generating section (14) generates program information specifying the broadcast program being currently received by the receiver (11), and then gives the program information to a communication section (15). The communication section (15) communicates with a program distribution center (5) to receive program data corresponding to the generated program information by streaming. The program data received through communication is reproduced instead of the broadcast program by the reproducing section (12).

Tuning scheme for code division multiplex broadcasting system

A CDM satellite transmission system is disclosed that broadcasts programming content, such as audio and video information, using one or more geo-synchronous satellites based on Code Division Multiple Access technology. Forward error correction coding and interleaving are used prior to broadcasting the signals over the CDM channel to account for signal loss due to short-term fading. The CDM satellite transmission system provides a tuning channel corresponding to each program channel that reduces the delay when a mobile receiver is first tuned to a selected program channel. The tuning channel utilizes a shorter interleaver length, if any, than the corresponding primary program channel. The CDM satellite transmission system transmits a delayed version of a program signal with the on-time version of the audio output to accommodate uninterrupted reception in the event of such a blockage. In one implementation of the invention, the core layer, C(n), of the delayed version of the audio output of a scalable audio coding scheme is utilized as the tuning channel. The core layer, C1(n), and enhancement layers, E1(n), of the on-time signal and the enhancement layers, E2(n), of the delayed-time signal employ a representative block interleaver having a duration of four seconds. The tuning channel (C2(n), of the delayed-time signal) employs a representative block interleaver having a duration of 500 milliseconds.
