Rails layout on the DISCOVER screen

By default, OpenTV ION will use the value of Default Rail image Orientation to determine the orientation of the images on a rail. When Landscape is selected, images use a 16:9 aspect ratio; when Portrait is selected, a 2:3 aspect ratio is used. You can override these layouts by adding an additional ui_layout property.

To set an additional property:

1. Select the template for the DISCOVER screen and select the appropriate layout.

2. Click on the rail that you want to add additional properties to and then click Edit Rail Properties.

3. Click Add Property and enter the relevant values shown in the sections below.

4. Click Save Rail.

5. In the confirmation dialog that is displayed, click Continue to save the rail.
