METHOD FOR DECODING OF SINGLE RECEIVED CURRENT SIGNAL FROM SEQUENCE OF TWO-CHANNEL ENCODED VIDEO SIGNALS AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1998 - IPC

FIELD: video equipment. SUBSTANCE: decoder provides base channel and extension channel and has frame loss detector for detection of cell frame from extension. In this case extension data of previous video signal which are shifted by shifter according current movement vectors are used as data for interpolation of lost frames. Interpolation data are added to decoded base channel according to adder. Extension data are produced by subtraction of previous base video signal which is stored in memory unit from previous decoded video signal which is stored in memory unit according to subtracter. EFFECT: increased image quality. 6 cl, 5 dwg
