Abstract: En general, se describen técnicas para indicar la reutilización de parámetros de trama para vectores de decodificación. Un dispositivo que comprende un procesador y una memoria puede realizar las técnicas. El procesador puede configurarse para obtener un flujo de bits que comprende un vector representativo de un eje espacial ortogonal en un dominio de armónicos esféricos. El flujo de bits puede comprender además un indicador de si se debe reutilizar, de un cuadro anterior, al menos un elemento de sintaxis indicativo de la información utilizada al comprimir el vector. La memoria puede configurarse para almacenar el flujo de bits. (Traducción automática con Google Translate, sin valor legal)

Abstract: In general, techniques are described for performing a vector-based synthesis with respect to higher order ambisonic coefficients (or, in other words, spherical harmonic coefficients). A device comprising a processor may be configured to perform the techniques. The processor may perform the vector-based synthesis with respect to spherical harmonic coefficients to generate decomposed representations of the plurality of spherical harmonic coefficients and determine distinct and background directional information from the directional information. The processor may then reduce an order of the directional information associated with the background audio objects to generate transformed background directional information, and apply compensation to increase values of the transformed directional information to preserve an overall energy of the sound field.

Abstract: 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.

Abstract: In general, techniques are described for indicating frame parameter reusability for decoding vectors. A device comprising a processor and a memory may perform the techniques. The processor may be configured to obtain a bitstream (21, 450) comprising a vector representative of an orthogonal spatial axis in a spherical harmonics domain. The bitstream may further comprise an indicator for whether to reuse, from a previous frame, at least one syntax element indicative of information used when compressing the vector. The memory may be configured to store the bitstream.
