ABSTRACT:
In a wide picture format television transmission system, the signals for the scene (1, 2, 3, 4) are transmitted as first and second television signals. The first television signal contains signal information relating to a portion (1, 5, 2, 6) of the scene of a standard aspect ratio while the second television signal contains signal information relating to the remaining portions (1, 2, 3, 5 and 1, 6, 3, 4) of the scene. The first television signal can be compatible with television signals currently broadcast. In order to enable the first television signal to relate to the area of main interest of the scene, it may be derived from a moveable portion between extreme portions of the scene. In order to correctly combine the information from the first and second television signals at a receiver for a correct wide picture format display, the second television signal additionally comprises a component in the form of a steering pulse.
