Multi-channel video encoding apparatus and method

摘要

An apparatus and method for encoding multi-channel video signals using a single encoder by a space division technique or a time division technique. In the multi-channel video encoding apparatus, a signal extraction unit extracts synchronous signals and active video data from received video signals. A decimation filter unit spatially decimates the extracted active video data according to the number of channels. A synchronization, unit synchronizes the decimated active video data for channels. An encoding unit encodes the synchronized decimated active video data received from the synchronization unit. This multi-channel video encoding apparatus can independently encode multi-channel video signals at the same time using a single encoder.
