Abstract:
A multimedia decoder which comprises:a memory configured to buffer an audio bitstream, wherein the audio bitstream includes a sequence of audio data packets;an audio decoder coupled to the memory to receive the audio bitstream, wherein a decoder pointer is used to determine which byte of the audio bitstream is to be provided to the audio decoder next;a bypass module coupled to the memory to retrieve the audio bitstream, wherein a bypass pointer is used to determine which byte of the audio bitstream is to be provided to the bypass module next, wherein the bypass module is configured to determine a difference between the bypass pointer and the decoder pointer, wherein the bypass module is configured to compare the difference to a predetermined threshold, and wherein the bypass module is configured to retrieve and transmit audio data from an audio data packet if the difference has a magnitude that does not exceed the predetermined threshold.
