Abstract:
1. A receiver terminal device comprising: a stream receiver configured to receive a stream; a program selecting unit configured to select a particular stream from the received stream based on program selection information; a stream controlling unit configured to perform path control of the particular stream; a storage device configured to store the particular stream transmitted from the stream controlling unit; and an output controlling unit configured to output a video/audio signal based on the particular stream transmitted from the stream controlling unit; wherein the stream controlling unit comprises: wherein, if the monitoring unit detects an initial state, the stream controlling unit performs path control such that a first stream selected by the program selecting unit is transmitted to the output controlling unit, the initial state indicating that the first stream is selected for a first time, and wherein, if the monitoring unit detects a first state, the stream controlling unit performs path controls such that a stream in the first stream following the point in time at which a second stream is selected by the program selecting unit is stored in the storage device, the first state indicating that the first stream is switched to the second stream.
