Abstract:
A method comprising:decoding a first frame of audio data; generating a first audio time stamp ATS1 indicating the time at which decoding the first frame of audio data has finished; decoding a second frame of audio data in response to decoding the first frame of audio data; generating a second audio time stamp ATS2 indicating the time at which decoding the second frame of audio data has finished; adding a predetermined amount of time T to the first audio time stamp ATS1, wherein T is added to ATS1 in response to generating ATS2; comparing ATS2 with (ATS1+T); if ATS2 is later in time than (ATS1+T) by the predetermined amount TMIN, generating a signal indicating that ATS2 is later than (ATS1+T); if ATS2 is not later in time than (ATS1+T) by a predetermined amount TMIN, generating a signal indicating that ATS2 is not later than (ATS1+T).
