摘要

A system and method for recording and reconstructing a high definition video on a standard definition DVD. A recording system is provided that comprises: a system for scaling down an HD video to an SD video format; a system for encoding the SD video; a system for extracting enhancement information from the HD video; and a system for storing the SD video and the extracted enhancement information onto the SD compatible medium. A playback system is provided for reconstructing the HD video image from the standard definition SD format recording, comprising: a system for extracting and decoding SD data from the recording; a system for extracting enhancement information from the recording; a system for de-interlacing the decoded SD data; and a system for up-scaling and post-processing the decoded SD data with the enhancement information to generate the HD video image.
