Abstract:
1. A signal processing apparatus comprising: a receiving unit which receives a non real-time stream including compression-encoded data via a network, the stream being formed by packets to which time stamps are respectively added; a generating unit which generates a first real-time stream from the stream received by the receiving unit, based on the time stamps added to the packets in the stream received by the receiving unit to output the first real-time stream from an output port; a broadcast receiving section configured to receive a broadcast signal and to output a second real-time stream including compression-encoded broadcast program data; a selector unit having a first input port connected to the output port and a second input port connected to the broadcast receiving section to input the second real-time stream, the first real-time stream generated from the non real-time stream being fed back internally within the signal processing apparatus from the generating unit to the first input port, the selector unit selecting one of the first real-time stream input to the first input port and the second real-time stream input to the second input port; and a decoding unit which decodes the one real-time stream selected by the selector unit.
