44.3.2. Output Subsampling and Color Space

You can configure the Test Pattern gGnerator IP output subsampling and color space to either be fixed and set at compile time, or to be variable at run time using the Avalon memory-mapped control agent interface.

The Output Format parameter sets the subsampling option:

  • 4:4:4. Output is fixed at full sampling for each color plane (can be RGB or YCbCr). Each pixel has 3 color planes.
  • 4:2:2. Output is fixed at full sampling on the Y plane and horizontal subsampling on the Cb and Cr planes (RGB data is not supported in 4:2:2 mode). Each pixel has 2 color planes.
  • 4:2:0. Output is fixed at full sampling on the Y plane and horizontal and vertical subsampling on the Cb and Cr planes (RGB data is not supported in 4:2:0 mode). Each pixel has 3 color planes.
  • Monochrome. Output has only 1 color plane per pixel and represents only a fully sampled Y plane.
  • Variable. Output can be configured at run time to be 4:4:4 RGB, 4:4:4 YCbCr, 4:2:2 YCbCr, or 4:2:0 YCbCr. Each pixel has 3 color planes.

The IP allows you to select up to 8 different test pattern configurations to switch between at run time:

  • Each configuration is a combination of 1 of the 3 available patterns and a formatting option.
  • Each test pattern configuration is fixed in one particular output format. However, by selecting between the patterns, you can vary the overall output format at run time.

For example, you may include 4 different configurations, all of which use the bars pattern, but with the first configuration set to 4:4:4 RGB, the second set to 4:4:4 YCbCr, the third set to 4:2:2 YCbCr, and the fourth set to 4:2:0 YCbCr. With this setting, you can validate all the possible configurations of an HDMI 2.0 output.
