Apparatus for receiving a digital information signal comprising a first video signal producing images of a first size, and a second video signal producing images of a second size smaller than the first size

摘要

An apparatus includes inputs configured to receive first and second video signals. The first video signal represents a sequence of images having a first size, and the second video signal representing a sequence of images having a second size, the second size being smaller then the first size of the images. The apparatus further includes a combiner configured to combine the first and second video signals so as to obtain a composite video signal suitable for displaying on a display unit. The combiner combines the first and second video signal while the size of the images corresponding to the second video signal remains unchanged.
