<p>PROBLEM TO BE SOLVED: To provide an apparatus and method for encoding video signals, in particular, multi-channel video signals using a single encoder by a space division technique or a time division technique. SOLUTION: In the multi-channel video encoding apparatus, a signal extraction unit 201 extracts synchronous signals and active video data from received video signals. A decimation filter unit 202 spatially decimates the extracted active video data according to the number of channels. A synchronization unit 203 synchronizes the decimated active data for channels. An encoded unit 204 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.</p> |
