DIGITAL VIDEO PROCESSING |
摘要 |
To inhibit unauthorised copying, the standard timing reference signals in a Rec 656 digital video signal are stripped out and replaced by a single timing reference per frame. Authorised equipment contains the processing to reconstruct the necessary timing from these timing references. Additionally, the digital words can be scrambled by bit re-ordering or by a more sophisticated process.
