Abstract:
1. A buffer control device comprising: a reference time generation unit configured to generate a reference time based at least in part on time information included in a data stream input; a buffer configured to receive an encoded data extracted from the data stream, store the encoded data, and output the encoded data at a decoding time or a reproducing time of the encoded data, the encoded data comprising a plurality of encoded data types, the plurality of encoded data types comprising video data, audio data in a first form, and audio data in a second form; a control unit configured to control an input of the encoded data to the buffer based at least in part on a relativity between the decoding time or the reproducing time of the encoded data and the reference time; and wherein the control unit is configured to calculate a difference between the decoding time or the reproducing time of the encoded data and the reference time, and stop the input of one of the plurality of encoded data types to the buffer when the difference is larger than a predetermined threshold for the one encoded data type.
