Coax Cable or Fiber Optic Cable for your HD-SDI HDTV signal

We've been getting more involved with broadcasting lately and I've been bumping into the HD-SDI SMPTE 292M standard. I thought these two videos shed some good light on the matter, the coax video compares three of our most popular broadcasting coaxial cable and how far a HD-SDI signal can be carried over each cable. The second video is an overview of a broadcast deployable fiber cable for harsh environments such as laying on a football field sideline during a snowstorm, being stepped on, coiled and uncoiled and whatever else the broadcasting life throws at it.





I'm glad the Society of Motion Pictures and Television Engineers have been working so hard over the past few years on establishing these standards. I love high definition television, especially when watching the NFL.

How to convert HD-SDI to HDMI?

Many HD broadcasting cameras are pushing out a HD-SDI signal that needs to be viewed using a HDMI connection on the other end. You'll need a HD-SDI to HDMI convertor, these converters are compliant with the Society of Motion Picture and Television Engineers (SMPTE) standard of 292M and 296M. These standards support data rates up to 1.485 Gb/s.

Everfocus model number EHA-SRX is capable of receiving HD-SDI digital video signal up to 1920x1080 resolution over 75ohm coax cable. This converter will provide a complete solution for the transmission and display of both interlaced and progressive scan HD-SDI digital video. Yes Everfocus is a security camera manufacture but don't worry, this will work for your broadcasting cameras too!

Let's get a look at it from our YouTube Channel



Features:

* Accepts HD-SDI digital video at 720p/60, 1080i/60 and 1080p/30 formats/frame rates

* Processes HD-SDI standard SMPTE 292M and 296M at 1.4585 Gb/s data rate

* Provides standard HDMI output for HD TV monitor display

* Integrated cable equalizer for long distance video transmission without loss of quality

* Capable of receiving HD-CCTV digital video over 75ohm coax cable at distanced over 100 Meters

* High quality digital video and audio transmission with zero latency

Now let's dig into the cable transmission. The EHA-SRX allows a total signal attenuation of up to 43.56 dB along the cable between devices. The actual maximum cable length depends on the attenuation characteristic of the particular cable being used. So if you have a long coax run make sure you have a kick ass quality cable so you have a lower signal attenuation.

I feel like I nailed this blog post, reminded myself of Kirk Lazarus from Tropic Thunder "I don't read the scrip, the scrip reads me."

HD-SDI DVR is perfect for recoding HD brocasting TV Cameras!

I get a phone call from a local television studio looking for a solution to record four Panasonic HDX900 cameras. The catch was we need it to record a HD-SDI signal since that's what the camera output is.

We decided to install the Everfocus EPHD04. Records HD-SDI and real time 30fps.

 

Let's check out some of the features.

* Full HD recording and playback

* Independent HDMI main and VGA call multiplex view monitor outputs

* Two internal hard drives support up to 3TB each

* External HDD array option so you can record up to 18TB

* Control with the front panel, IR remote and optional joystick controller

* Multiple remote access: IE web access, Smart Phone and Tablet live view

* The smart search lets you quickly identify motion in areas of interest from recorded video

My customer was installing this for a Food TV show starring someone with the name of Giada De Laurentiis? I only know of Guy Fieri because people have mention to me "You remind me of that food network star, Guy Fieri."

This HD-SDI DVR worked out great for his TV show application. He did mention this was awesome because, then he talked about a ton of broadcasting lingo that I'm not familiar with but I'm glad it worked out for him. The one thing I do remember is how much he said this was a perfect application for reality TV shows. I think it'll be real cool if I can get that bounty hunter show to order one of these. I am the dog the bounty hunter!

Interested in what else this Bad Boy HD-SDI DVR can do? Check out the manual and data sheet.

Thanks!
