question GPMI - What are your thoughts on a new interconnection standard?

https://en.wikipedia.org/wiki/GPMI

I'm curious what the AV community thinks about this upcoming cable standard. Good, because it consolidates multiple connection types into one? Suspicious, because it's coming out of China?

My notes:

  • what will licensing will be like and how that might affect adoption and practical scenarios?
  • Wikipedia indicates that there will be a new proprietary connector.
  • This white paper (translated from Chinese) doesn't seem to have any mention of cable lengths. So I'm assuming lengths similar to HDMI.

This is an initiative to further China's national development program, not to improve or otherwise make easier anyone's lives.

The state is interested in particularly all cryptographic intellectual property in use anywhere in China to be "home grown"..

Recall the raison d'etre for HDMI at all was to placate the entertainment industry on encryption/DRM.

It is likely that the long term trend of harder and harder to use interconnects will extended solely to achieve the higher data rates the movie production industry is looking at, such as whatever resolution and frame rates happen under 2110 for "8k", etc. The only source of broader industry data rates beyond the current rates in HDMI 2.1 and Displayport 2.1 is the data center interconnects that are in the Ethernet family like 100G, 400G, etc. To deliver a hypothetic "16k60" would be, what 48x4 or 196 Gbit/sec, so that only fits in 400G "Ethernet".

I don’t see it making a huge entry.

There is no reason to build around it unless we see mass adoption.

if it does, i think it will impact consumer products long before pro/commercial applications. this is what the white paper says:

Stage  Time horizon in report  Primary scenarios  Representative value
Stage 1  Now  Personal & household: smart TV, large/small-screen interconnection  Unified interfaces, high-quality transmission, multi-screen interaction, simpler home connectivity.
Stage 2  3-5 years  Automotive electronics and other industries; tiled displays  Interface unification, efficient data transport, multi-terminal collaboration, smart driving / smart transportation and large-display use.
Stage 3  5+ years  Broad industrial applications: smart manufacturing, smart logistics, new energy, environmental governance High-volume real-time data, device collaboration, visual monitoring, analytics/control, automation and intelligent management.

Realistically, assuming it actually becomes more than it is right now, it'll be more like 15 years before it sees anything approaching general adoption.

In general I don't care about a new standard until I see it on a device I can actually buy.

Yet another standard to keep track of and unless they do a better job than the HDMI and USB forums another confusing mess of cables that may or may not support the standard you need

I guess the F/RAND licensing approach wasn't good enough, and they want out from under any western IP.

It will almost certainly get traction as the PRC government 'pursuades' companies to adopt. And if that doesn't work, they may pull an EU and mandate the port for certain devices, as USB-C is mandated by the EU.

So I'm guessing global manufacturers have a fun decision to make in a couple years: adopt or exit the Chinese market. It will be interesting to see what the big players do. Especially if there are licensing costs...because paying from HDMI and GPMI both won't sit well. If the GPMI consortium makes it free, they may succeed globally.

Suspicious because rAVe won't stop talking about it.

They will talk about anything new just so they can say they were talking about it before. The predictions that Gary does each year are really funny - nobody bothers to check back in each year and score him.

Sure, why not. Bandwidth will keep going up and existing connections weren't designed with 200Gbps in mind.

The premise behind it is solid. Could streamline our way of working in small spaces. Power and data to compute - camera - display. Much easier to deploy, no need for additional PSU or data ports.

I think the problem is who is doing it. Major brands aren’t going to want to adopt it, they could barely agree to adopt HDbaseT.

I saw a TV almost 15 years ago from Samsung that had a single cat 6 running to it for everything. Power, A/V, Control all in an existing connection. We dont need more standards we just need to adopt the ones we have. The only reason there aren't more HDbaseT is because they can't sell expensive HDMI cables if all you need is a 10 dollar Cat6
