How much data can we save at the server using SVC?
following table of bitrate (kbps) of different bitstreams from iDASH shows the SVC can save 56% storage at the server. Although SVC encoded bitstream has penalty of compression efficiency 10% - 15%, the SVC encoded bitstream can be decoded multiple times with different resolution, frame rate and quality and there is dependency between different layers. Since the AVC encoded bitstreams are independent, the total bitrate is 5000 kbps, while the bitrate of SVC is 2200. Therefore there can be a huge reduction in terms of storage consumption.
