Our customer want to detection of signal or nosignal of NTSC imput.
Signal detection use register of VDEC_VIDMOD field descriptions of bit "0" Have signal to set "1".
And detection level use VDEC_VSSGTH field description of "nosigthresh".
Would please tell me what mean nosigthresh step by step valu.
If set to 0x001,Is this detect noise voltage? or noise period?
There are set to 0x101 is wlong. noise detection.
But set to 0x111 is no ploblem noise is no detect.
