ADV7181D, about data output during the blanking period.

Category: Datasheet/Specs
Product Number: ADV7181D

Hi,

I have a question about data output of ADV7181D during the blanking period.
Some devices (device A) output the Data 0 signal during the blanking period, but others (device B) don't output Data 0 signal during the blanking period.
* Please see the attached file for more details.

[Question]
- Is it normal for the ADV7181D to output Data 0 during the blanking period?

Could you answer by May 19th?

Regards,

    All video parts ADV7480) will send the video data (Active region) + Blanking data (Non-active region) and note that in the blanking areas, HDMI will carry the audio data and infoframe packages.

    Generally Info-frames and audio packets will ride in the blanking areas.

    [Question]
