CODING INDEPENDENT FRAMES OF AMBIENT HIGHER-ORDER AMBISONIC COEFFICIENTS

摘要

In general, techniques are described for coding an ambient higher orderambisonic coefficient. An audio decodingdevice comprising a memory and a processor may perform the techniques. Thememory may store a first frame of a bitstream and asecond frame of the bitstream. The processor may obtain, from the first frame,one or more bits indicative of whether the first frameis an independent frame that includes additional reference information toenable the first frame to be decoded without reference tothe second frame. The processor may further obtain, in response to the one ormore bits indicating that the first frame is not anindependent frame, prediction information for first channel side informationdata of a transport channel. The prediction information maybe used to decode the first channel side information data of the transportchannel with reference to second channel side informationdata of the transport channel.
