pattgen_dl_mapping

1

Input

Dual link mapping. Set to 1'b1 for HD-SDI dual link and 3Gb transmit video standard only.

pattgen_ntsc_paln

1

Input

Transmit rate.

  • 0: PAL (1) rate. For example, 1080p30
  • 1: NTSC (1/1.001) rate. For example, 1080p29.97.

This input ignores all SD video formats (525i, 625i) and certain HD video formats that do not support NTSC rate (1080i50, 720p50, 720p25, 1080p25).

1

Input

Generate color bars.

  • 0: 75% color bars
  • 1: 100% color bars
pattgen_patho

1

Input

Set to 1'b1 to generate pathological pattern.

pattgen_blank

1

Input

Set to 1'b1 to generate black signal.

pattgen_no_color

1

Input

Set to 1'b1 to generate bars with no color.
