Definitions
- PCT patent WO0007361A relates to a unidirectional digital video broadcasting network in which the data of HTML Internet web pages is formatted so as to fit into a standard MPEG-2 data packet structure, then multiplexed with other digital video signals MPEG-2 in sight. This card is updated and rebroadcast each time a modification occurs at the start, in the middle or at the end of a broadcast video program, the web pages with simultaneous transmission being synchronized with the digital multichannel video programs broadcast.
- patent WO0165832A1 is also known concerning a system and a method making it possible to receive information linked by hypertext links to a television program. According to the invention, the broadcast material is analyzed and one or more regions are identified within a frame.
- the invention relates, according to its most general meaning, to a method of temporal marking of a video signal intended for television broadcasting, characterized in that it includes a step of recognizing a graphic element in the video stream and conditional generation of a marking signal in the event of detection of said graphic element, said marking signal being associated with at least part of the video sequence containing said graphic element.
