LOSSLESS MULTI-CHANNEL AUDIO CODEC USING ADAPTIVE SEGMENTATION WITH RANDOM ACCESS POINT (RAP) CAPABILITY

LOSSLESS MULTI-CHANNEL AUDIO CODEC USING ADAPTIVE SEGMENTATION WITH RANDOM ACCESS POINT (RAP) CAPABILITY

A lossless audio codec encodes/decodes a lossless variable bit rate (VBR) bitstream to initiate lossless decoding at a specified segment within a frame. This is accomplished with an adaptive segmentation technique that fixes segment start points based on constraints imposed by the existence of a det...

Zusammenfassung:A lossless audio codec encodes/decodes a lossless variable bit rate (VBR) bitstream to initiate lossless decoding at a specified segment within a frame. This is accomplished with an adaptive segmentation technique that fixes segment start points based on constraints imposed by the existence of a detected transient in the frame and selects an optimum segment duration in each frame to reduce encoded frame payload.
