A muted and extremely ecological niche revolution may be underway : according to reputation out of China , HDMI is on its last legs . Its successor ? GPMI .
If all that sound like a bunch of vaguely familiar random letter of the alphabet to you , though , here ’s why it ’s important .
What is HDMI?
HDMI stands for High - Definition Multimedia Interface , and if you ’ve ever set up … well , just about anything with a projection screen , really – a television receiver , amonitor , a jut silver screen for a intro , whatever – then you ’re credibly intimate . They reckon like this :
They ’ve been around since 2002 in some form or another , though the exact stipulation has been update as engineering science has progressed – the most recent variant , HDMI 2.2 , for instance , can deal 96 gigabits of information transport per second ( Gbps ) , which is a huge improvement from 2002 ’s 4.95 Gbps .
Originally , they were quite the innovation . order had only just made the switch to digital rather than analogue connectors , and the most democratic means to link up your cutting - edge screens was via a DVI cable’s length .

These work okay – they still do , in fact , in gadget old enough to support them – but HDMI had advantages that made its coup all but inevitable : it substantiate both audio and visual components , rather than DVI ’s visual only ; it could be linked up with CEC ( Consumer Electronics Control ) , allowing devices to communicate across producer and constituent ; it came in one essentially universal selection ; and perhaps most impactfully , it had integrated digital copyright technology – and thus the championship of major medium companies .
“ HDMI is the first video and audio measure to hoard accompaniment from the integral CE [ consumer electronics ] value chain , from content providers to system operator to CE producer , ” Wanda Meloni , then president of digital media technology company M2 Research , said in astatementback at the launching of HDMI . “ consumer have been eagerly awaiting more compelling high - definition message , and HDMI should unlock the floodgate . ”
Still , though , the connectors were n’t perfect . They were proprietary ironware , meaning that manufacturers had to give to include them – and as ourTVsand PCs get ever higher specs , some are already worrying that even 96 Gbps wo n’t be enough somewhat presently .
What is GPMI?
Enter the GPMI – or to expend its full name : the General Purpose Media Interface . Announced before this month by China ’s Shenzhen 8 K UHD Video Industry Cooperation Alliance , this cable port standard can reportedly support up to 192 Gbps of picture and audio – twice that of the still yet - to - be - relinquish HDMI 2.2 – as well as delivering both datum and up to 480 watts of power supply . For those keeping count , that makes it even more of an all - in - one result than the HDMI cablegram it may replace .
Like HDMI , it ’s stake by industry heavyweight like Huawei , Hisense , and TCL – though , notably , none outside of China . It ’s also obtain official approval from the USB Association , harmonize to Hong Kong’sHKEPC , so it should n’t have compatibility issues with the hardware already in use .
That said , there ’s notnothingnew going on here . Alongside the USB - light speed type GPMI cable is a raw , proprietary , “ Type - B ” cable , and it ’s this that has the headline - snap up 192 Gbps/480W capacitance – the USB - C connexion only manages half of each . Why that is , precisely , is unclear – whether it ’s because USB - C literally ca n’t cope with such high transfer rates ; to ensure USB 4 compatibility ; or if it ’s just a tactical move to establish the form of iron hold in the marketplace that HDMI has so far enjoyed , is not yet established .
Either way , GPMI plain has quite a few advantages over its predecessors , assume everything terminate up work out out . Even if only the USB - degree Celsius connecter gets taken up , with its identical transferee rate to the upcoming HDMI 2.2 , there ’s still the power - communion welfare , as well as a blow potential difference for “ daisy strand networking technology”,persemiconductor ship’s company HiSilicon , one of those championing the new standard , and sustenance for two - agency control organization . Presumably , being non - proprietary , it ’ll also be a turn cheaper to admit , which might make it more tempting for manufacturers .
“ GPMI is an innovational achievement and a core technical breakthrough in the audio recording and telecasting industry , ” order HiSilicon in atranslated statement . “ It integrate the functions of TV transmission , information interaction , web connection and power supply , and realise that one interface can affirm the full byplay needs of ' audio and video + data point + web + ascendency + power supply ' . ”
Which just leave one enquiry : when should we expect to see these new cables twine out ?
Do we need to buy all new cables now?
light answer : probably not .
Long result : all we have is a few announcements right now , and even if everything works out without a unmarried hitch , we still should require a reasonable wait before compatible ware start turning up in store . After all , it took close to two years for consumer HDMI products to reach the shelves back in 2002 - 3 – and while there’sbeen noiseabout “ multiple mathematical product image ” being released “ within the year ” , no specific products have yet been announced that will contain it .
But , frankly , “ without a individual rub ” is not a render here . So far , this tech is not being comprehend alfresco of China , and it ’s unclear how enthusiastic westerly companies are going to be about adopting it . GPMI willreportedlyinitially prioritize “ menage amusement equipment ” like TVs – but big names like LG , Samsung , and Sony have n’t dedicate , and those three combine make up a full 50 percent of the global telly market place .
And amongst all these potential snag , there ’s one factor that ca n’t be overlooked : as it stands , HDMI and USB - C are … fine ? Okay , GPMI has advantages , but they ’re not necessarily gamechangers over the status quo – especially from the tip of view of manufacturers and metier companies .
Basically , this declaration is tease for wonk ( lovesome ) – but not a reason to go out and substitute all thedevicesand cables in your firm right now . Give it five yr , though , when we ’re all rocking 256 K 7680Hz interactive surroundings - sound smellovision television receiver in our living rooms – well , thenwe might need to change to GPMI .
