Digital video processor with subvideo processor |
摘要 |
An improved architecture for a digital video processor that processes subvideo data to be superimposed on a main video image during a display image scanning process. The improved digital video processor divides and partitions the execution of subvideo data between a programable CPU and a dedicated hardware processor. The CPU is used to process the simpler, less time critical, nonpixel data, and the more complex, more time critical pixel data is processed in real time using a dedicated hardware processor operating under the control of the CPU. The improved digital video processor is adaptable to process subvideo data being supplied in different data formats.
