Coding independent frames of environmental higher-order ambisonic coefficients

摘要

In general, techniques for coding environmental higher-order ambisonic coefficients are described. An audio decoding device comprising a memory and a processor can perform this technique. The memory can store a first frame of the bitstream and a second frame of the bitstream. From the first frame, whether the processor is an independent frame that includes additional reference information to allow the first frame to be decoded without reference to the second frame One or more bits indicating whether or not can be obtained. The processor further obtains prediction information for the first channel side information data of the transport channel in response to the one or more bits indicating that the first frame is not an independent frame. Can do. The prediction information may be used to decode the first channel side information data of the transport channel with reference to the second channel side information data of the transport channel.
