Video broadcasting signal time marking method for synchronizing video program with enriching function, involves generating marking signal when graphical unit in video sequence is detected, and associating signal with part of sequence

摘要

The method involves recording a video sequence for recognizing a graphical unit in the video flow. A conditional marking time signal is generated when the graphical unit in the sequence is detected. The marking signal is associated with a part of the video sequence containing the graphical unit. The video sequence is synchronized with enriching functions according to the marking signal. Independent claims are also included for the following: (a) equipment for generating a synchronization signal in the video sequence (b) a process for conditional visualization of a video sequence.
