Fiber based matrix switch?


ERDrPC

Question

Has anyone found a card based Fiber matrix for video distribution. I know crestron has their DM series and it looks great but I love C4. I remember reading a while back that someone was going to try to use a DM for a C4 install while creating some sort of bridge between a c4 controller and a Crestron one. Did it work?

I'm going to be renovating and want to run multimode fiber along with a couple audioquest cat 7 and an rg-6 per node.

 The new Jap which was recently announced seems cool but still relies on cat bandwidth. When 4:4:4 at 60 p comes out, I don't think there will be enough bandwidth. Now I am installing a Cisco based network with 10g bandwidth using a combo of sfp+ between my mikrotek router top of the rack switch and 10g Ethernet to my computers and equipment. Too bad Jap can't develop using 10g as a backbone.

With the hdmi spec at 2.0a currently and things in the pipeline like Dolby vision, Fiber should have the capacity to run everything (even 8k when it's out in ?2022).

You have to realize that none of the content anyone is providing you is truly uncompressed. Whether Comcast, ATT, Dish, DirecTV, or OTA - netflix, amazon, and others. That overhead isnt likely to be reached in the near future due to transmission costs - the race is always on for better encoding.

Netflix's example: ( http://techblog.netflix.com/2015/12/per-title-encode-optimization.html ) or the spec for bitrates on ultra HD blu-ray (https://en.wikipedia.org/wiki/Blu-ray#Ultra_HD_Blu-ray) 128 mbit/s on a 100GB disc and using HEVC encoding. Here's the CEO of Just Add Power describing how they manage 4K over the existing gigabit switching infrastructure. http://www.remotecentral.com/cgi-bin/forums/viewpost.cgi?1291973

If you want to toss around truly uncompressed HD video (likely that you've shot yourself), that's quite a bit of data.

" A 1920 x 1080 video signal with 4:2:2 sub-sampling and 10-bit color depth will take up a huge amount of space, about 10GB per minute. And there are a few recorders available, such as the Blackmagic Design Hyperdeck Shuttle 2 that will record fully uncompressed video. But if you are looking for something that takes up less space than 600GB an hour, then you probably want some form of compression applied to your image.  "

It's great to future proof with fiber, or even better, conduit - as the more likely scenario is that HDMI will be replaced/supplemented by another cable such as a variant of display port, superMHL, or something else.

So, if it were me: 

1) conduit

2) 2-4 Shielded cat6 to each location, or if youre burning money cat7 and a dark fiber.

the challenge is investing in infrastructure today on the expensive bleeding edge in anticipation for an unpredictable CE future. Ask anyone who pre-wired S-video or component or composite without a way to re-run cabling. As technologies come and go so must the infrastructure of the smart home adapt or remain stagnant. Accessible conduit allows you to go "bang for your buck" today but with peace of mind for flexibility for whatever tomorrow brings.

 

Anyway, just my .02.
