METHOD AND DEVICE FOR PLAYING VIDEO DATA OF HIGH BIT RATE FORMAT BY PLAYER SUITABLE TO PLAY VIDEO DATA OF LOW BIT RATE FORMAT

摘要

A player which is capable of playing a video data of low bit rate format, e.g., DVD-VR format, can not play a video data of high bit rate format, e.g., BD-RE format unless the video data is transcoded. Transcoding of video data generally requires a large size storage area. Based on an original navigation information for the video data of high bit rate format, a predictive navigation information for the video data of low bit rate format is generated. Using the original and predictive navigation information, the transcoding is done by sections.
