ABSTRACT:
A television signal encoder uses correlation between frames for data compression or reduction in redundancy of information to be transmitted. The coding error occurring in the interframe coding process is effectively corrected by low-bit intraframe coding with limited increase in the volume of coding information. This permits raising the significance determination threshold value without impairment of picture quality.
