摘要:
A method and apparatus for changing codecs to reproduce video and/or audio data streams are provided. The method and apparatus are capable of seamlessly reproducing video and/or audio data streams encoded with two or more different codecs when a change of codecs occurs by determining in advance the start position of a program element at which a change of codecs occurs among video and/or data streams stored in buffers using information regarding a change of codecs included in a data packet and changing the codec used for decoding at the moment when the program element at which the change of codec occurs is first decoded.
