A circuit for horizontally displaying a first standard aspect-ratio television picture and a reduced-size second standard aspect-ratio television picture on a wide aspect-ratio television display includes a first and a second video signal supply and a circuit for selecting one of the video signals as the first standard aspect-ratio television picture and the other of the video signals as the second standard aspect-ratio television picture. The video signal for the first standard aspect-ratio television picture is then time compressed while the video signal for the second standard aspect-ratio television picture is initially sub-sampled to reduce the size of the resulting television picture and is then time compressed. These two compressed video signals are then selectively applied to the wide aspect-ratio television display so that the reduced-size second standard aspect-ratio television picture appears beside the first standard aspect-ratio television picture.
