AV OVER IP: IS THIS THE SLOW DEATH OF HDMI?

Sound + Image - - News -

There are un­con­firmed ru­mours of an al­liance brew­ing be­tween Cre­stron and Mi­croso” and In­tel, with the goal of de­vel­op­ing a plat­form for net­work­ing of 4K video. Aim­ing to dis­place both HDMI and HDBaseT ca­bling, the fo­cus on com­pres­sion to a 1GB/s stream would bring the AV-over-IP stan­dard within the realms of next-gen­er­a­tion home net­work­ing, whereas the higher-spec 10GB/s sys­tems are more de­signed for pro­fes­sional AV in­stal­la­tions — although sup­port­ers of 10-gig tech­nol­ogy point to the in­evitable Moore’s Law growth of speed and ca­pac­ity in all net­work­ing, so that 1-gig sys­tems (cur­rent ex­am­ples use JPEG2000 or H.264 en­cryp­tion) may quickly be seen as a need­less stop-gap and a po­ten­tial gag on qual­ity through ex­ces­sive com­pres­sion.

Although many will be de­lighted at any­thing that could sig­nal a move be­yond the re­stric­tions of HDMI, the fo­cus on sig­nal se­cu­rity will in­evitably re­main, and for home sys­tems in par­tic­u­larly we can be near-cer­tain of the im­po­si­tion of an end-to-end check on se­cu­rity us­ing HDCP-style copy pro­tec­tion.

As noted above, Cre­stron is not yet o§icially con­firm­ing the ex­is­tence of the new al­liance.
