Is it possible to connect boards via HDMI?

Question

Electronics

Dear colleagues, is it possible to use the HDMI interface instead of Ethernet to connect the boards?
What, in fact, is the idea: the network input on the board has a limited bandwidth. The video output probably has a higher data rate.

Answer 1

Can. In this case, according to the standard, the direction of transmission will be only in one direction. From the side of the receiver, you can make requests via i2c, which is provided for by the standard. However, all this can work correctly on video receive / transmit blocks only if you come up with a data presentation format so that they fit well into the video frame. If you have an FPGA, then you can not take a steam bath and transfer data in any order and format, but you should coordinate this with both the receiver and the transmitter, and then no one will forbid you to transfer data via HDMI.

Answer 2

Common sense dictates that if this approach had any chance of competing with normal solutions, it would be implemented. Common sense dictates that if it were implemented, Google would know about it . Common sense dictates that if you knew how to use Google, you wouldn't be asking this question.
How are you with common sense, colleague?

Answer 3

Can. The speed will be no more than 100 megabits. You will need specialized hdmi ports and an expensive cable. And shamanism with how it all works. Fuck goat button accordion?)

Answer 4

Maybe just take 10 gigabits ethernet?

Answer 5

Itself saw how two switches a stack on HDMI kept. But it worked like this
