Abstract
A video CD reproduction controlling device comprising a CD-drive, a CD-ROM decoder, an MPEG decoder, an address storing unit for storing disk reproduction information read out from the first track on a video CD, and a controller for controlling each of the above units, the controller storing an address of moving image data recorded on the first track included in the disk reproduction information, into the address storing unit, and controlling the CD-drive, the CD-ROM decoder, and the MPEG decoder so as to reproduce the moving image data recorded on the first track by use of the address stored in the address storing unit, in the reproduction of the moving image data at the reproduction mode with playback control-off.
Claims12
A video CD reproduction controlling device, mounted with a video CD on which at least disk reproduction information indicating reproduction procedure for reproducing moving image data compressed and encoded in a predetermined compression method, is recorded on the first track and the compressed and encoded moving image is, when present on the first track, recorded thereon, and the compressed and encoded moving image data is recorded on the second track and the later, for controlling reproduction of the moving image data recorded on the video CD, the video CD reproduction device comprising:
- a CD drive, mounted with a video CD, for reading out the data recorded on the video CD;
- a first decoding means for decoding the data read out through said CD drive, so to supply reproduction data;
- a second decoding means for decoding the moving image data, so to supply image signals and sound signal, when the reproduction data supplied from said first decoding means is the moving image data compressed and encode nu the predetermined compression method;
- a storing method for storing disk reproduction information read out from the first track, of the reproduction data supplied from said first decoding means;
- and
- a controlling means for controlling said CD drive and said first and second decoding means,
- said controlling means
- storing into said storing means, an address of moving image data recorded on the first track, included in the track, of the reproduction data supplied from said first decoding means, and
- controlling said CD drive and said first and second decoding means so as to reproduce the moving image data recorded on the first track by use of the address stored in said storing means, in the reproduction of the moving image data at the reproduction with playback control-off.
A video CD reproduction method for controlling reproduction of moving image data recorded on a video CD, by mounting in a CD-drive, the video CD on which as least disk reproduction information indicating reproduction procedure for reproducing moving image data compressed and encoded in a predetermined compression method, is recorded on the first track and the compressed and encoded moving image data is, when present on the first track, recorded thereon, and the compressed and encoded moving image data is recorded on the second track and the late, the video CD reproduction controlling method comprising the steps of:
- a step of reading out the data recorded on the video CD mounted in the CD-drive;
- a step of decoding the data read out from the video CD, so to supply reproduction data;
- a step of storing an address of the moving image data recorded on the first track, included in the disk reproduction information read out from the first track, of the reproduction data;
- and
- a step acquiring the moving image data recorded on the first track by use of the recorded address, in the reproduction of the moving image data at the reproduction mode with playback control-off.
A computer readable memory storing a control program for controlling a video CD reproduction controlling device, provided with a CD-drive for mounting a video CD on which at least disk reproduction information indicating reproduction procedure for reproducing moving image data compressed and encoded in a predetermined compression method, is recorded on the first track and the compressed and encoded moving image data is, when present on the first track, recorded thereon, and the compressed and encoded moving image data is recorded on the second track and the later, for reproducing the moving image data recorded on the video CD, the control program comprising:
- a step of reading out the data recorded on the video CD mounted on the CD-drive;
- a step of decoding the data read out from the video CD, so to supply reproduction data;
- a step of storing an address of the moving image data recorded on the first track, included in the disk reproduction information read out from the first track, of the reproduction data;
- and
- a step of acquiring the moving image data recorded on the fist track by use of the recorded address, in the reproduction of the moving image data at the reproduction mode with playback control-off.
