The UDC-8225A-W provides broadcast quality conversion with letter / pillar insertion between any standard and high-definition formats. This is an excellent solution for applications where 4:3 aspect ratio is maintained through the up conversion to a 16:9 aspect ratio. In these applications the second input is provided as a fill for the letter / pillar bar area. The UDC-8225A-W automatically inserts the fill without the need for an alpha channel simplifying configuration and graphic creation. Cropping of the fill insertion is offered to remove any edge effects. The letter / pillar bar insertion is a field upgradable option to the UDC-8225A.
