METHOD FOR TRANSFERRING SYNCHRONOUS TELEVISION SIGNALS OF MULTI-GRADATION IMAGES Russian patent published in 2005 - IPC

FIELD: technology for transferring images, can be used for concurrent transmitting and receiving within frequency band of one digital television image signal, N synchronous television signals of multi-gradation images, formed using, for example, television cameras or other sources of black and white, colored, spectrum-zonal, volumetric, or other multi-gradation images, and also can be used for concurrent recording and conservation of N synchronous television signals of multi-gradation images, and can be possibly utilized for construction of video-surveillance systems, television systems for remote probing of Earth surface and multimedia video-information transfer systems.

SUBSTANCE: method for transferring synchronous television signals of multi-gradation images includes, at transferring side, operations for processing and transformation of N synchronous analog television signals to N synchronous digital television signals, by means of their analog-digital transformation, forming of digital synchronization signals, transmission of signals via communication channel, and at receiving side, reversed operations over signals are performed to in comparison with transmitting side, during which after forming of digital synchronization signals, aforementioned signals are joined as one multi-level resulting signal S by means of analog-digital transformation of N synchronous digital signals, further, multi-level resulting signals S is added to synchronization signal, amplified and transferred along communication channel, and at receiving side multi-level resulting signal S is amplified, then synchronization signals are separated from it, controlling and clock pulses are formed, then, operation of analog-digital transformation of multi-level resulting signal S is performed and N synchronous digital television signals are formed in serial code, after that, operations over signals are performed, being reversed relatively to those at transferring side, namely, each digital signal, represented by serial code, is transformed to parallel n-byte binary code, then, forming of N source analog synchronous television signals of multi-gradation images is performed by means of their digital-analog transformation.

EFFECT: possible concurrent transmission of N synchronous analog television signals of multi-gradation images within frequency band of one analog signals, transformed into television form.
