处理媒体信号的装置及其方法
Abstract:
本发明公开了一种处理媒体信号的方法及其装置。根据本发明的媒体信号解码方法包括：检测将被生成的多声道中的具备有效值的声道，及由缩减混音信号和空间信息信号生成所述检测到的具备有效值的声道。因此，本发明检测将由传送到的媒体信号生成的声道中的哪个声道是被设置为虚拟值，并且省略用于生成设置为虚拟值的声道的解码，所以能减少解码操作量。
Abstract(English):

The present invention relates to a method of processing a media signal and apparatus therefor. A media signal decoding method according to the present invention includes detecting a channel having a valid value of the multi-channels to be generated and generating the detected channel having the valid value from the downmix signal and the spatial information signal. Accordingly, the present invention is able to reduce a decoding operation quantity by detecting which one of the channels to be generated from a transferred media signal is set to a virtual value and omitting decoding for the generation of the channel set to the virtual value.
