Features of the 8K DisplayPort Video Format Conversion Design Example

  • Input:
    • DisplayPort 1.4 connectivity supports resolutions from 720x480 up to 3840x2160 at any frame rate up to 60 fps, and resolutions up to 7680x4320 at 30 fps.
    • Hot-plug support.
    • Support for both RGB and YCbCr (4:4:4, 4:2:2 and 4:2:0) color formats at the input.
    • Software automatically detects the input format and sets up the processing pipeline appropriately.
  • Output:
    • DisplayPort 1.4 connectivity selectable (via DIP switches) for either 1080p, 1080i or 2160p resolution at 60 fps, or 2160p at 30 fps.
    • Hot-plug support.
    • DIP switches to set the required output color format to RGB, YCbCr 4:4:4, YCbCr 4:2:2, or YCbCr 4:2:0.
  • Single 10-bit 8K RGB processing pipeline with software configurable scaling and frame rate conversion:
    • 12-tap Lanczos down-scaler.
    • 16-phase, 4-tap Lanczos up-scaler.
    • Triple buffering video frame buffer provides frame rate conversion.
    • Mixer with alpha-blending allows OSD icon overlay.
