Hello,

Thank you for writing.

Yes, it is verified working. The video data can be captured with BT1120 protocol.

Furthermore,It is SAV/EAV mode for 1280x720@30fps YUV422, not VSYNC+HSYNC mode.

I hope this can help you.

 

Best Regards,

Diego.

Hello Diego.

I have one more question.

Could BT.1120 support 1280x720@60fps YUV422 video output?

> Yes, it is verified working. The video data can be captured with BT1120 protocol.

Furthermore,It is SAV/EAV mode for 1280x720@30fps YUV422, not VSYNC+HSYNC mode.

Is this a result of video input?

I hope to know about 720p60 video output by bt1120 format.

Best regards,

Ishii.

Yes, the code is ready. The only difference, is the clock frequency. The code is the same.

Best regards,

Hello Diego

Thank you for your support.

Please teach me which environment do you use to test it?

If you use this patch https://community.nxp.com/docs/DOC-94019 

which point do you modify to test it?

If not, can we get a sample code or setting for it?

Best regards,

Ishii.
