ABSTRACT:
Visual data in a first color format stored in first memory locations are merged with visual data in a second color format, which different from the first color format, stored in second memory locations to form a merged pixel stream. An analog signal is generated representative of the merged pixel stream. In a preferred embodiment, one set of visual data is graphics data in an 8-bit CLUT format and the other set is video data in an 8-bit packed YUV9 format (also known as the 4:1:1 format). In this embodiment, the video data is unpacked and chromakeying is applied to generate the merged pixel stream.
