Abstract:
1. An apparatus for receiving a digital information signal comprising at least a first video signal, a second video signal and a parameter signal, the apparatus comprises: a receiver configured to receive the digital information signal; a first retriever configured to retrieve the first video signal from the digital information signal; a second retriever configured to retrieve the second video signal from the digital information signal; and a combiner having three inputs for receiving the first video signal, the second video signal and the parameter signal, respectively, the combiner being configured to combine the first and second video signal so as to obtain a composite video signal suitable for displaying on a display unit, wherein the first video signal represents a first sequence of images having a first display size, and the second video signal representing a second sequence of images having a second display size, the second display size being smaller than the first display size of the images and having a reduced resolution lower than a resolution of the first video signal when displayed on a display unit in a full screen format, wherein the combiner is further configured to combine the first and second video signals while the display size of the images corresponding to the second video signal remains unchanged for display of the second video signal having the reduced resolution, wherein the digital information signal further comprises a playlist, and wherein the playlist includes an extended list including a stream type specifying a stream as being one of the first video signal and the second video signal having the second sequence of images of the second display size and the reduced resolution for forming the composite video signal for simultaneous display of the second sequence of images overlaid on the first sequence of images on the display unit when selected by a user.
