VIDEO INFORMATION RECORDING DEVICE, VIDEO INFORMATION RECORDING METHOD, VIDEO INFORMATION RECORDING PROGRAM, AND RECORDING MEDIUM CONTAINING THE VIDEO INFORMATION RECORDING PROGRAM

摘要

A control unit 102 in a digital broadcast receiver 100 finds a motion vector by performing the encoding into an MPEG-4 format partially and records the motion vector thus found into a recording unit 103 as a motion vector stream 147 in parallel with processing to encode program contents into an MPEG-2 format and to record program contents 141 encoded in the MPEG-2 format into the recording unit 103. The control unit 102 then generates program contents in the MPEG-4 format from the program contents 141 in the MPEG-2 format and the motion vector stream 147 recorded in the recording unit 103 to enable the use in another device 131.
