Information processing method and apparatus

摘要

An information processing apparatus in which compressed picture information of different compression encoding formats may be generated and recorded on different recording mediums without enlarging the size of the apparatus. An MPEG2 encoder 2 is supplied with the picture information and encodes the input information in the MPEG 2 format under control by a CPU 3 to generate an MPEG 2. A hard disc drive 5 records the MPEG2 bitstream on the hard disc under control by the CPU 3. The CPU 3 boots a software on a memory to perform transcode processing to generate an MPEG 4 bitstream from the MPEG2 bitstream. The motion vector as found in transiently decoding the MPEG2 bitstream into the picture information is inherited and re-used as the motion vector for the MPEG 4 bitstream. A memory card drive 6 records the MPEG 4 bitstream on the memory card under control by the CPU 3.
