Abstract
A method and apparatus is disclosed for using multiple scalers to scale video and graphics data. A video data is capable of accessing data formats not accessible by a graphics engine, pipeline, or scaler. The video data can be accessed by the video scaler and subsequently converted to a data format accessible by the graphics engine, pipeline or scaler. The converted video data can be routed to memory. Once stored in memory, the data can be accessed for further processing, such as additional scaling or graphics processing. In addition, the converted video data can be output directly to a processor, such as a graphics processor for additional processing.
