Abstract: A process of time division marking of a video signal intended to be televised including recording an image base, image elements or reference video sequences; comparing a video stream with the image base; recognizing a graphic element in the video stream; and conditionally generating a marking signal when the graphic element is detected, which marking signal is associated with at least a part of the video sequence containing the graphic element.

Abstract: A process for transmission of a digital televised broadcast including interactive advertisement sequences which can be activated at least in part by a television viewer including transmitting elemental advertisement components materialized in the form of codes calling up native functions, comprising components of “INITIALIZATIONS”defining positioning in a data structure of other components, components of “DRAWS” corresponding to graphic representations materialized in the structure in the form of codes calling up native factions of a host language of a digital terminal, components of “PALETTES” corresponding to color palettes and components of “SCREENS” corresponding to screen descriptions, and constructing an animated image by superposition of an animated image background corresponding to a principal broadcast and an image grouping together at least a part of elemental components by an execution program loaded in the digital terminal.

Abstract: The invention concerns a device for long-distance transmission of a television program on a single channel and a process including transmitting a first video signal corresponding to a main program comprising advertising video images interposed between video broadcasts, and a second video signal corresponding to an optional advertising program and including a sequence triggering the recording in a temporary rapid storage, recording in a temporary rapid storage the second signal when the triggering sequence is detected and continuously transmitting the first signal to a display circuit. The first signal includes graphic signaling means for activating the restitution of the video signals stored in said memory.
