ABSTRACT:
Each line of a wide aspect ratio television signal is divided into a main panel component and two augmentation panel components for transmission or storage. The two augmentation panels are transmitted in a multiplex analog format on the same channel. They are transmitted adjacent to one another so that additional signals such as audio signals will occupy the same time slots regardless of the respective widths of the panels. (The sum of the panel widths remains constant even in pan and scan operations). Weighted transition augmentation samples effect a transition from the last redundant pixel of one augmentation panel component to the first redundant pixel of the second augmentation panel component.
