METHOD AND DEVICE FOR DECODING COMPRESSED MULTI-MEDIA COMMUNICATION AND EVALUATING QUALITY OF MULTI-MEDIA COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a multi-media decoder capable of detecting errors in multi- media bit streams while considering the time of decoding separated sound and/or video bit streams and warning the presence of the errors to a sound and/or video decoder.;SOLUTION: The multi-media decoder is provided with a system decoder 720 for receiving the multi-media bit stream 765 and supplying at least one of the sound bit stream 727 and the video bit stream 737 together with a first error signal 736. Whether or not at least one of the sound bit stream and the video bit stream includes data with the error is identified by the first error signal.;COPYRIGHT: (C)2001,JPO
