HDMI vs. SDI Video Connections

On this episode of BoxCast Tech Tips, Josh compares two commonly used video connections: HDMI and SDI.

That coax cable on the SDI description slide looks like it's 50ohm antenna cable not 75ohm SDI cable.

To be perfectly accurate (and somewhat pedantic), those HDMI extenders don't convert to Ethernet, they convert to Cat5E/Cat6 cable. Ethernet is a type of network, not a particular type of cable.

Great video - short, fun and to the point!

Josh this is Wayne LWCCC. Thanks for this video. We were just thinking how to run or what type of cabling to use for our Panasonic Hv camcorders with the hdmi converter box. We are also converting our coaxial cabling end tips with coax to sdi connectors so we don't have to undo all the coaxial cabling we ran. So this helps!!! Thanks for the tech tips

I have a Panasonic AG-HVX 200. How would SDI work for this camera? I want that kind of security but don’t see an SDI output. Any help for this novice would be greatly appreciated!

Hi,
In another video, i realized that there are cameras that have "CLEAN" and "DIRTY" HDMI output signals. Referring to the Overlay text and glyphs that are sent, and would NOT be desirable in a live set up.
How does this work with SDI?

[learnsomethingeveryday]

Do both cables carry audio signals from the cameras

[georgehsmith]

Can i conect a standard sdi device to a HD-SDI device? Or put another way is SD-SDI compatable with HD-SDI?

[malikplayz]

has anyone ever tried the hd-link with cameras before? is so, please tell me your review

I have never seen an STI connection, but I do not do professional video. If I were to purchase an HDMI to SDI converter (transmitter/receiver), would I be able to use a BNC T to split the signal out to two TVs without the need of an expensive splitter?
According to the website these converter sets go 300', and from what I can tell they are running at 75ohms. So, if I have 2 or more tvs, and additional receivers, could I successfully split the split the signal providing the total length of all cables do not exceed that 300'?
Since the signal is unilateral the transmitter should not be able to tell it is split, and since they receivers are not "mated" to their transmitters, they should only see a reduction in signal strength. It is however expensive for me to test this theory and it appears you have everything to try it out :)

my camera has RCA output. how do i use this SDI to split the signal to 3 TV's?

[samuel.gabura]

This is a cable and connector comparison, not a signal comparison.
I was expecting some sort of an explanation on how come that the HDMI has many pins and SDI is just a single wire (by the looks of it).

Josh, this is joshua too :)

HD- TVI Converter to HDMI | VGA | CVBS | Problem | November 2016

Problem im having in Splitting VIDEO SIGNAL.

I have installed the DVR bellow, with 4 fish eye cameras. They are 1080p 2.4MP cameras. Also included int he details are three TVI to HDMI/VGA/CVBS to Three LED 40 inch TV's. SO far the converter has worked, but the image is Glitching and I get the eight colors of no input signal, and it will come back.


Details.

I have connected everything, but I am getting interupted signal loss eveno tho i have the converter box that plugs into the wall.

(4) RG59 Siamese cable.
(1) Power Box 12V 10amp ( i believe). ( will update soon )


Conclusion

I was under the impression that with the converters i can split the signal and with the amplifier not have any issues. THe only thing I have not done is try the CVBS to the TV using a BNC/RCA to the VIdeo Input of the TV.
