Simultaneous, multi-aspect ratio television display

In an HDTV system having apparatus and a video display means for providing a display of video signals having a 9:16 aspect ratio, a device for selectively simultaneously providing on said video display means a plurality of 3:4 aspect ratio displays of video signals, each constituting a respective image, and all said images being substantially completely non-overlappingly tiled,

• said device comprising:
• a horizontal synchronizing counter for counting horizontal synchronizing signals associated with said first display of video signals having a 9:16 aspect ratio;
• a vertical synchronizing counter for counting vertical synchronizing signals associated with said first display of video signals having a 9:16 aspect ratio;
• a logic control matrix part operatively connected with said horizontal and vertical synchronizing counters, for providing control signals related to counts respectively provided by said counters;
• a plurality of signal sources each arranged to provide, when selected, a respective set of video signals for a respective video display of a respective image having a 3:4 aspect ratio;
• a switching block effectively connected to said logic matrix part and to said logic control matrix part, for switching among said plurality of signal sources, depending upon said control signals, and thereby providing successively switched-to signal sources successively to an output means of said switching block;
• a scan position data transfer part effectively connected to said output means of said switching block for transferring scan position data for said 3:4 aspect ratio images to be displayed on said video display means of said HDTV system;
• and
• an image processor effectively connected to said scan position data transfer part for processing said 3:4 aspect ratio images, so that each is displayed on a distinct portion of said video display means with none of said 3:4 aspect ratio images substantially overlapping one another.
