METHOD AND DEVICE FOR RECORDING AND REPRODUCING VIDEO DATA AND DATA CARRIER, ON WHICH VIDEO DATA ARE RECORDED USING SAID METHOD AND DEVICE Russian patent published in 2005 - IPC

Abstract RU 2266625 C2

FIELD: technology for recording and reproducing video data, and also hypertext data.

SUBSTANCE: prior to recording on data carrier, video data, primarily encoded by main method, are decoded and information about video data properties is extracted, decoded video data are encoded by method, different from original method and video transformation information is produced, which should be used for displaying video data in original state on basis of information about properties, and generated video transformation information is recorded together with recoded video data on data carrier.

EFFECT: correct reproduction of video data and data with hypertext, even if video data were repeatedly encoded by different method and recorded.
