Abstract:
According to an embodiment, a video compression apparatus includes a first compressor, a second compressor, a partitioner and a communicator. The first compressor compresses a first video to generate a first bitstream. The second compressor sets regions in a second video and compresses the regions so as to enable each region to be independently decoded, to generate a second bitstream. The partitioner partitions the second bitstream according to the set regions to obtain a partitioned second bitstream. The communicator receives region information indicating a specific region that corresponds to one or more regions and selects and transmits a bitstream corresponding to the specific region from the partitioned second bitstream.
