Abstract: A reception unit receives data whose bit rate varies. A signal processing section 118 converts the data received by the reception unit into data of a data format to be transmitted to a client apparatus and stores the data obtained by the conversion into a buffer 120. When data is stored by a given amount into the buffer 120, a transmission section streaming-distributes the data to the client apparatus. A control section 126 additionally stores, when data is not stored by the given amount into the buffer 120 in a given transmission period, dummy data into the buffer 120 until the given amount is reached, and controls the transmission section to transmit the resulting data.

Abstract: A receiver receives a stream of program data that includes: an image signal including a plurality of frames; a sound signal; and a playback timing signal used for synchronized playback of the image signal and the sound signal. A clock signal generation unit generates a clock signal that is independent of the playback timing signal. A reception timing signal acquisition unit acquires a reception timing signal indicating a receiving time of the program data. An analysis unit analyzes a trend of time-dependent variation in a detected difference between the reception timing signal and the playback timing signal. An adjustment amount generation unit generates an adjustment amount of the clock signal, which causes the difference between the reception timing signal and the playback timing to be constant, by referring to a trend of time-dependent variation analyzed by the analysis unit.
