DEVICE FOR RECEPTION OF TV SIGNALS Russian patent published in 2000 - IPC

FIELD: TV equipment, in particular, prevention of unauthorized access to information transmitted through communication channel. SUBSTANCE: device uses compression and splitting components of TV signal with respect to their shapes. Processing of parallel orthogonal code combinations of processed TV signal which represents sum of orthogonal signals in communication channel is provided by receiving correlation devices of system using splitting of TV signals with respect to their shape. Total code combinations from output of receiving station are sent to input of TV signals receiver, which provides demodulation of brightness signal, basic colors signal, synchronization pulses signal, line and frame scanning signals, soundtrack signal. EFFECT: increased functional capabilities. 1 dwg
