Abstract
A television picture coding device which includes in particular a motion-estimation stage, a control circuit for controlling the motion-estimation stage, a coding stage, and a multiplexing stage, is characterized in that the original images are constituted by interlaced fields and partitioned into information blocks. The motion-estimation (110) includes displacement vectors determining circuits (201, 202, 210) and a format converting circuits (230). The controls stage (130) includes a comparator for making a comparison between a recovered non-transmitted field, to be recovered on the reception side, and an original field corresponding therewith, and a modifying circuit for modifying information components to be transmitted in case of an excessive distortion between the compared fields. A coding stage (120) is included for performing a spatial coding, and multipling stage for multiplexing the signals produced by the coding stage, the motion-estimation stage and the control stage.
