14.2. Initializing the Clocked Video Input IP

The IP provides an Avalon memory-mapped interface, which you can use as a control interface to configure the IP. Initially, the IP is disabled and does not transmit any data or video. However, the Clocked Video Input IP still detects the format of the clocked video input and accepts data on the input video interface.

To start the output of the IP:

  1. Write a 1 to control register bit 0 to enable the clocked video input block
  2. Write a 1 to control register bit 4 to enable Vsync and Hsync autopolarity detection.
  3. Optionally, write a 1 to control register bit 3 to enable the frame cleaner logic.
  4. Optionally, write the minimum expected number of frames for F0 and F1 to control register bits 23:16 to enable autodetect interlaced video format mode. If you write zeros to this set of bits, the IP does not automatically auto-detect video interlaced formats.
  5. Write the expected output video height and width values to ref_lock_cfg1 register. The IP only starts transmitting video on the output interface when the values on ref_lock_cfg1 matches the values on registers active_line_count and total_line_count.
  6. Write the expected number of frames and output video lines values to ref_lock_cfg2 register. The IP only starts transmitting video on the output interface when the values on ref_lock_cfg2 are matched.
  7. Alternatively, if you write zeros to ref_lock_cfg1 and ref_lock_cfg2, the IP does not try to match any specific output video resolution values and immediately produces video.
  8. Optionally, set the values for each of the color planes that the frame cleaner use to do the padding on the output video frame in case a cable is pulled.
  9. Read status register bit 4. When this bit is 1, the IP starts transmitting video. The transmission starts on the next start of frame boundary.
