Abstract
A system and method are provided for reducing burden on real-time processing when combining overlay or crawl text with a primary video image. Based on a crawl rate of the crawl text, the method includes determining fractional pixel values associated with the crawl rate and pre-filtering the overlay or crawl text based on the established fractional pixel values, and combining windows of the various and appropriate pre-filtered overlay or crawl text with the primary image for encoding and delivery.
