音频声道与音频物件之音频编码及解码的概念;CONCEPT FOR AUDIO ENCODING AND DECODING FOR AUDIO CHANNELS AND AUDIO OBJECTS

摘要

本发明揭露一种音源编码器，用以编码音源输入资料(101)以取得音源输出资料(501)，其包含：一输入介面(100)，用以接收复数个音源声道、复数个音源物件以及有关于至少一该复数个音源物件之一元数据；一混合器(200)，系用以混合该复数个物件以及该复数个声道以获得复数个预混合声道，每一预混合声道系包含一声道之一音源资料以及至少一物件之一音源资料；一核心编码器(300)，系用以核心编码一核心编码器输入资料；以及一元数据压缩器(400)，系用以压缩有关于该至少一该复数个音源物件之该元数据，其中该音源编码器系用以在一组两种模式的至少一模式下操作，该两种模式包含一第一模式，在该第一模式下该核心编码器系用以编码该复数个音源声道和该复数个音源物件，该复数个音源声道和该复数个音源物件系由该输入介面所接收以作为核心编码器输入资料，以及一第二模式，在该第二模式下该核心编码器(300)系用以接收由该混合器(200)所产生之该复数个预混合声道，以作为该核心编码器输入资料。; a mixer (200) for mixing the plurality of objects and the plurality of channels to obtain a plurality of pre-mixed channels, each pre-mixed channel comprising audio data of a channel and audio data of at least one object; a core encoder (300) for core encoding core encoder input data; and a metadata compressor (400) for compressing the metadata related to the one or more of the plurality of audio objects, wherein the audio encoder is configured to operate in at least one mode of the group of two modes comprising a first mode, in which the core encoder is configured to encode the plurality of audio channels and the plurality of audio objects received by the input interface as core encoder input data, and a second mode, in which the core encoder (300) is configured for receiving, as the core encoder input data, the plurality of pre-mixed channels generated by the mixer (200).
