Device for converting a motion information into a movement detection signal with the desired number of lines and half picture frequency for a high resolution television receiver.

摘要

The present invention relates to a device for the transformation of a motion information into a signal of detection of movement to the frame frequency, and the number of lines that are desired for a receiver of high definition television. / p & & p & this device comprises: - at least two memories 10, 11 for storing to the frame frequency of the input video signal, respectively, of the data relating to the motion information of the even-numbered frames and the data relating to the motion information of the odd frames, these memories are read at the frame frequency of the video signal to be displayed; - a processing circuit 20, 30, 40, 50 connected to the output of the memories, said circuit delivering, from the motion information read to the frame frequency desired, a detection signal of the movement applied to the frame frequency, and the number of lines that are desired synchronous with the video signal to be displayed. / p & & p & application to the high definition television.
