PVSP Video Output Module

Figure 55 shows the structure of the PVSP VOM. The direction arrow inside
the VOM but gives a clear overview of each processing block.
The VOM has the following main features:
•
Pixel unpacker: this module reads the field/frame from external memory and unpacks memory words to video pixel information
• VOM cropper: crops the image read from external memory
•
De-interlacer: converts interlaced video to progressive video
• CUE correction: filtering for Color Upsampling Error
•
Noise reduction: removes random, mosquito, and block noise
• Detail and edge sharpness enhancement
