FERNSEHAPPARAT UND VERFAHREN MIT EINRICHTUNGEN ZUR ANZEIGE EINES ZUSATZBILDES VARIABLER GRÖSSE

摘要

In order to selectively reduce the size of an auxiliary image, such as may be displayed within main image during a so called "picture-in-picture" or "PIP" mode of operation of a television system, a fixed amount of the auxiliary image is caused to be cropped from the auxiliary image without changing the compression ratio of the compressed auxiliary video signal from which the auxiliary image is derived.
