METHOD AND DEVICE FOR COLLECTING MULTI-STANDARD VIDEO INFORMATION Russian patent published in 2005 - IPC

FIELD: accumulation of multi-standard video information.

SUBSTANCE: method for gathering multi-standard video information, which contains for different providers of information different frame synchronization codes or launch codes with certain frequency for different information providers, contains steps, during which it is determined, relatively to which type of frame synchronization codes or launch codes it is necessary to perform a standard search, based on number of current string, in accordance to used standard of input signal; input flow of data is loaded into first memory device; parallel search of frames synchronization codes or launch codes is performed by comparison of inputted data flow to given codes, while target codes are subject to configuration alteration, and search process is performed during active range of search window at frequency, adapted to frequency of target frames synchronization code or launch code; in case of detection of frame synchronization code or launch code data is sent to buffer.

EFFECT: detection of data providers in video signals strings.
