METHOD FOR SEARCHING SYNC WORD IN THE ENCODED AUDIO BITSTREAM AND COMPUTER READABLE MEDIUM THEREOF

摘要

The method involves determining whether data in a MPEG compressed audio bitstream has a value equal to a sync word value. The data is a valid sync word or not is found based on a comparison of a set of data separated from the former data by a frame length to the value. The length is found based on a bitrate index field value and/or a sampling frequency field value included in a header associated with the bitstream. - Independent claims are also included for the following: - (A) a decoder circuit for searching for a sync word in an MPEG compressed audio bitstream - (B) a computer program product for searching for a sync word in an MPEG compressed audio bitstream.
