DVP-53A Board (XKS-8470)

The DVP-53A board consists of the following blocks.
• SDI input/output block
• PVMIX block (Pre Video Modify & MIX)
• FINTPU block (Filter & Interpolator)
• AINTPL block (Address Generator & Interpolator)
• VMIX block
The DVP-53A board is controlled by the local CPU module (CPU-DP) on this board.
SDI input/output block: IC5, IC6
This block converts the SDI signal sent from the cross point block (XPT-38 board) to parallel signal, and then sends the
parallel signal to the PVMIX block.
This block eliminates phase differences in input signals and performs video processing (including video level adjustment
for each input).
Furthermore, this block converts the signal sent from the VMIX block to SDI signal, and sends the SDI signal to the
cross point block (XPT-38 board).
PVMIX block: IC11
This block sends the video/key signals received from the SDI input/output block to the FINTPU block and sends the
return video/key signals processed in the FINTPU block and the AINTPL block to the PVMIX block.
The PVMIX block has the following main functions.
• Border/Crop/Beveled Edge
• Video Modify (including Posterization, Solarization, and Mosaic)
• Input Freeze
• Mask key generation
• Recursive
FINTPU block: IC7, IC8
This block first performs horizontal Defocus/Blur and Filtering processing (Antialias Filter) according to the reduction
rate. Then this block sorts data (Scan Conversion) using the DDR2 SDRAM and then performs vertical Defocus/Blur
and Antialias Filter processing. The video/key signals are sent to the AINTPL block and are written to the DDR2 SDRAM
for interpolation.
After that, this block receives the address generated in the AINTPL block. Data is read from the DDR2 SDRAM
according to this address and horizontal interpolation processing is performed. Output data is sent to the AINTPL block.
The FINTPU block has the following main functions.
• Antialias Filter (in horizontal and vertical directions)
• Scan Conversion
• Defocus/Blur
• EffectG2 Mask or Mask
