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?

  • Hi,

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

           Please let us know, What type of data that are outputting during blanking period from device A.

    Thanks,

  • Hi,

    I would like to know about ADV7181D instead of ADV7480.

    The all setting conditions for device A and device B in the attached file are the same, such as input=CVBS, script etc.
    However, device A outputs data during blanking.
    And what I would like you to confirm is this behavior of device A is correct or not.
    Please let me know your thought on this.
