Abstract
A video signal processing arrangement for television signals encoded in digital form comprising means for compressing and/or expanding the size of the television picture represented by the video signal and means for rotating the television picture represented by the video signal is disclosed. The rotating means is separate from the compressing and/or expanding means and is switchable between a position prior to the compressing and/or expanding means in the video signal processing chain and a position subsequent to the compressing and/or expanding means. An arrangement having two separate video signal paths which are later combined to produce a composite picture is also described in which the rotating means can also be positioned after the combining means as well as before or after the compressing and/or expanding means in either path.
