Patent ID: 8428444

Claim:
A video server comprising: a storage unit configured to store first video data items and second video data items, the first video data items comprising a first plurality of frames encoded using intra-screen coding, the second video data items comprising a second plurality of frames encoded using inter-frame compression based on predictive coding; a processor configured to generate first and second data blocks, the first data block generated by combining a first number of first video data items from the storage unit, the second data block being generated by dividing a second video data item read from the storage unit; the processor configured to output the first data blocks in fewer frames than frames in which the first number of first video data items are read, and to output the second data block in a vacant frame, the vacant frame obtained based on a difference between the frames in which the first data blocks are output and the frames in which the first video data items are read; and a decoder configured to decode the first data blocks to generate first playback signals, output the first playback signals, and buffer the second data blocks.
