CONTENT STORAGE DEVICE

摘要

A content storage device (10) includes an MPEG4 codec (34). Compressed data on a motion picture outputted from the MPEG4 codec (34) at the time of capturing the motion picture is a motion picture content that expresses a continuous change with time and has "I" flame allocated intermittently. A CPU (40) stores such compressed motion picture data in a recording medium (38). The CPU (40) also prepares motion picture index data specifying each flame of the compressed motion picture data outputted from the MPEG4 codec (34). This preparation is performed simultaneously with the compression by the MPEG4 codec (34). The prepared motion picture index data is stored in the recording medium (38) by the CPU (40) every time the "I" flame is specified.
