Category: Datasheet/Specs
Product Number: ADV7611


Is there video mute function on ADV7611?

ADV748x has vmute in IO Map 0x0A but it looks ADV7611 doesn't have.



  • Hi Tomato San,

            YES, ADV7611 doesn't contain 'Vmute' register and if you want to mute the Video (i.e Black image to be sent across the HDMI link).

            Please enable the 'VID_ADJ_EN' register before configuring the color control registers, For pure black video output we need to change the contrast,saturation,hue and brightness value registers as zero.

            Also the black image can be useful for protecting copyrighted content during HDCP authentication.
