Abstract
Official abstract text for this publication.
In general, techniques are described for coding an ambient higher order ambisonic coefficient. An audio decoding device comprising a memory and a processor may perform the techniques. The memory may store a first frame of a bitstream and a second frame of the bitstream. The processor may obtain, from the first frame, one or more bits indicative of whether the first frame is an independent frame that includes additional reference information to enable the first frame to be decoded without reference to the second frame. The processor may further obtain, in response to the one or more bits indicating that the first frame is not an independent frame, prediction information for first channel side information data of a transport channel. The prediction information may be used to decode the first channel side information data of the transport channel with reference to second channel side information data of the transport channel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of decoding a bitstream including a transport channel specifying one or more bits indicative of encoded higher-order ambisonic audio data, the method comprising: obtaining, from a first frame of the bitstream including first channel side information data of the transport channel, one or more bits indicative of whether the first frame is an independent frame that includes additional reference information to enable the first frame to be decoded…
