Input Signal Format: Select the signal format for each input. The S-video and Composite Video connections are internally wired together. Therefore, only S-video or composite video can be connected to each input, but not both at the same time. Input 4 is fixed as RGB passive.

To configure the Inputs 1 - 3 for either a composite video or S-video format:

1.	Press the ENTER or MENU button to access the main menu.
2.	Highlight INPUT and press ENTER to access the input menu (use the			and arrow buttons to
	highlight the appropriate menu command).	￿	￿	￿￿
3.	Highlight SIGNAL FORMAT and press ENTER to access the signal format menu.
4.	Highlight the input you want to configure.
5.	Select the format for each individual input (use the		and buttons to toggle between composite

and S-video). The IN1403 will save the format setting￿automatically￿ .

It is critical that the composite/S-video status is selected properly for each input. Using the on-screen menu, you can set/change the input format at any time, even when another input signal is active. If the composite/S-video selection is set incorrectly, the decoder circuitry will not function properly and the IN1403 will display a distorted picture.

Aspect Ratio: The aspect ratio controls vary the relative image width and height. They can be used to accommodate various input signal aspect ratios as well as output device aspect ratios. Select the output aspect ratio by choosing the appropriate resolution in the output menu (see the output resolution description on page 14).

Standard: For Standard 1.33 input signals (sometimes referred to as full screen)

Anamorphic: This setting provides vertical image squeezing to accommodate anamorphically enhanced DVDs

Wide Screen: For wide screen 1.78 input signals (letterbox)

Wider Screen: For wider screen 2.35 input signals (narrow letterbox)

Tomarama: Designed for wide screen (letterbox) signals viewed on 4:3 aspect ratio displays. Tomarama mode zooms in on the center of the image and crops the image vertically and horizontally so that the black bars above and below the image are removed. In this mode, some image is also lost on the right and left hand edges.

Most DVDs and VCRs and other video sources output a signal with an aspect ratio of 4:3. How this signal is filled with active video information determines its aspect ratio. In the following four examples, four different input aspect ratios are shown on the left as they would be displayed in their native 4:3 format. The same signals are shown on the right as they would appear on 4:3 and 16:9 display devices with the scaler set to various aspect ratios.
