Abstract:
1. An information processing apparatus for reproducing from a recording medium a compression encoded video bit stream having a picture size in common with an NTSC range and a PAL range, a frame rate of 24 Hz or 23.976 Hz, and a progressive format, the information processing apparatus comprising: when the display format is the PAL range, means for reproducing the encoded video bit stream from the recording medium; decompression decoding means for decoding the reproduced encoded video bit stream and generating a video signal having a frame rate of 23.976 Hz or 24 Hz and a progressive format; video converting means for converting an output of the decompression decoding means into a video signal having a frame rate of 29.97 Hz, 59.94 Hz, 25 Hz, or 50 Hz; first determining means for determining whether the frame rate of the video signal on the recording medium is 24 Hz or 23.976 Hz; and second determining means for determining whether the display format of the video signal is 25 Hz or 50 Hz; wherein when the first determined value of the first determining means is 24 Hz, and when the second determined value of the second determining means is 25 Hz, the video converting means performs processing of displaying the first 11 encoded frames and the last one encoded frame repeatedly for two frames and three frames, respectively, every 12 encoded frames, and further performs processing of inserting one display frame into every 1000 display frames, and when the second determined value of the second determining means is 50 Hz, the video converting means performs processing of displaying the first 11 encoded frames and the last one encoded frame repeatedly for two frames and three frames, respectively, every 12 encoded frames, and further performs processing of inserting one display frame into every 1000 display frames.
