Circuit to separate and combine color space component data of a video image |
摘要 |
A method and arrangement for separating interleaved luminance and chrominance color space components data in a single data stream with minimum CPU intervention is provided. In the separating circuit, the separating circuit receives as input a series of graphics/video image data composed of interleaved luminance and chrominance color space components at successive clock cycles. The separating circuit directs selected bytes of the graphics/video image data representing the luminance color space component to a first path wherein luminance component data received at two successive clock cycles are combined. Likewise, selected bytes of the graphics/video image data representing the chrominance color space component are directed to a second path wherein chrominance component data received at two successive clock cycles are combined. Then, the combined luminance and chrominance component data are output alternately. Conversely, a method and arrangement for interleaving luminance and chrominance color space components data in stored separately into a single data stream is also provided.
