Abstract:
1. A content receiving apparatus comprising: a decoding unit for receiving, from a content providing apparatus provided at an encoder side, a plurality of encoded video frames to which video time-stamps based on a reference clock for the encoder side are attached and a plurality of encoded audio frames to which audio time-stamps based on a reference clock for the encoder side are attached, and for decoding the plurality of encoded video frames and the plurality of encoded audio frames; a storing unit for storing a plurality of decoded video frames that the decoding unit has obtained by decoding the plurality of encoded video frames and for storing a plurality of decoded audio frames that the decoding unit has obtained by decoding the plurality of encoded audio frames; a calculating unit for calculating a time difference resulting from a gap between a clock frequency of a reference clock for the encoder side and a clock frequency of a system time clock for the decoder side; and a timing-adjusting unit for adjusting a timing of outputting the plurality of decoded video frames, one by one, in accordance with the time difference and on the basis of a timing of outputting the plurality of decoded audio frames, one by one.
