Audio Coding Method and System for generating a decodable Bitstream through Unified Protocols implement different decoders decoding

摘要

In a class of Realizations, An Audio Coding System (usually a perceptual coding system that is configured to generate a single Bitstream (Unified) that is compatible with (i.e. a decodable) by a First Decoder configured to decode d Audio Data encoded according to a First Protocol (e.g., codingThe Protocol Multichannel Dolby Digital Plus or DD +) and a Second Decoder configured to decode audio Data encoded according to a Second Coding Protocol (e.g., Protocol I Stereo AAC, AAC HE AAC v2 or V1).The Bit stream may include both Unified coded Data (e.g., Data bursts) decodable by the first Decoder (and ignored by the second decoder) as encoded Data (For example, other Data bursts) decodable by the second Decoder (e IG For the first norados decoder).In fact, the second encoding format is hidden inside the current Unified bit when the first Decoder decodes The Bit Stream, and the first encoding format is hidden inside the current Unified bit when the second Decoder decodes The Bitstream.The Unified format of the Bitstream generated according to this can eliminate the need of transcoding in the whole chain and / or multimedia ecosystem.Other aspects of this are a Coding Method carried out by any one of the outputs of the encoder of the present, a decoding method carried out by any one of the outputs of the Decoder of the present, and a computer readable medium ( ExampleA Disk) that stores codes to implement any of the achievements of the present method.
