Circuitry for reading data from a picture memory

Abstract

Abstract In a circuit for reading data out of a picture memory of a DPCM loop, preferably of a narrow-band videophone, taking into consideration movements of the subject recorded, read addresses are generated by a sign-correct addition of addresses which, in the absence of movement, are used for reading-out of the picture memory (origin addresses), to data which identify the respective movement (movement vectors). <IMAGE>
