7.4.4. Configuring The Wide Screen Signalling Parameters

The Wide Screen Signaling signal is typically carried on lines 23 in 625-line systems. The wide-screen
signaling information is a data burst containing information on the aspect ratio range of the image in the
transmitted signal and its position, as it would appear on a conventional 4:3 display and on the position of
the subtitles and on the camera/film mode.
The WSS Setup menus are used to configure how the ARC Series modules will handle WSS. Table 7-7
shows the items available in the WSS Setup menu.
