lines are detected on a field
Allows high quality input shaping filter even if head switch detect type 1
detects head switches on the input
Allows high quality input shaping filter even if head switch detect type 2
detects head switches on the input
Allows high quality input shaping filter even if a noisy input is detected
Description
Disable HQI shape filter if very noisy input detected
Allow HQI shape filter even if noisy input detected
sdp_very_noisy_ip = 1. Refer to the Synctip Noise Measurement, Noisy and Very Noisy Signal Detection
Description
