ABSTRACT:
A system is described for the line-wise compression and decompression of a video color picture. The pixels are decoded in Y-U-V bit series, thus forming code words which each contain, for example six Y-bits of different significance and also one U-bit and one V-bit. The bit series, notably the more-significant series of Y-bits (Y5 . . . Y3) are independently compressed in a compression translator so as to from length indication codes. Furthermore, at least two bit series are combined in a logic circuit (44, 46, 48), the series of combination bits then being subjected to a compression operation (50). The reverse procedure takes place upon decompression.
