    摘要: For conversion of a first video signal into a second video signal of a different format, a second auxiliary data packet is generated from a header carrying location data for multiplexing a first auxiliary data packet and main data of a first auxiliary data packet in the first video signal, and is multiplexed with the second video signal. For conversion from the second video signal into the first video signal, the first auxiliary data packet is generated from the header and the main data of the second auxiliary data packet, and multiplexed at the location determined by the location data in the first video signal.

    摘要: A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.

    摘要: A number of outer parities to be added to an audio data is changed responsive to a ratio of frame frequencies of a video signal (e.g. 24 Hz or 30 Hz) before the data is recorded. Comparing with a first format, a recording bit rate is increased in a second format. Audio 4 channels (audio sectors 5-8) are additionally recorded maintaining a video data format (video sectors 1, 2) of the first format and an audio data format (audio sectors 1-4) of the first format.

    摘要: The picture reproduction apparatus of this invention reproduces compressed image data which has been compressed using inter-frame encoding, extracts a header from the reproduced image data, taking out intra-frame encoded image data using the information of the header. Invalid data is added to the image data other than the intra-frame encoded data. The image data is output into a picture decoding apparatus, so as to obtain a reproduced video image during playback in fast forward and fast reverse. Alternatively, valid image data is detected from the reproduced image data. In the slow playback at a 1/N speed, M (

    摘要: To improve the convenience of a record medium and allow a reproduction process to be more easily performed than before. When a reproduction process 123 that reproduces material data recorded on a disc 32 is executed, a disc information file management section 63 references a reproduction history of a disc information file held in a disc information file hold section 52 and starts reproducing material data from a position according to the reproduction history. When the reproduction process is completed, the disc information file management section 63 updates the reproduction history of the disc information file held in the disc information file hold section 52. A disc information file record control section 82 records the updated disc information file on the disc 32.

    摘要: To smoothly reproduce data. A data generation section 103 generates an essence data file composed of a file header, a file body, and a file footer. A header size obtainment section 108 obtains header size information of essence data file from the data generation section 103, and supplies the header size information to a clip generation section 104 and an index file update section 105. The clip generation section 104 generates a clip information file that describes the header size information supplied from the header size obtainment section 108. The index file update section 105 registers a clip element that describes the header size information supplied from the header size obtainment section 108 to an index file stored in a ROM. The present invention can be applied to a video program creation support system.
