The smallest and worst HDMI display
Article makes fun of how slow i2c is compared to the super high speed pairs next to it on HDMI plug.
Well, please note that there is a bus that is literally a thousand time slower than i2c on that same connector. It&#x27;s CEC. Contrary to i2c it only occupies one wire rather than two though.
CEC, which is used mainly to power TV on&#x2F;off or switch sources has a whopping bandwidth of 400bps. No missing multiplier.<p>Maximum device name is 16B. If you have a TV, a tvbox and a game console, simply asking the name of those devices can take more than a second.
I&#x27;m in the process of shortening my product&#x27;s CEC name, in order to reduce congestion on the bus.<p>Mainline Linux CEC developer jokes that Voyager 1 which is on the other side of solar system, made 40 years prior to CEC, is faster than CEC.<p>Edit: Sorry for the atrocious original formating
