Below are some cabling recommendations for your various broadcasting situations and scenarios. 


SDI Cabling

SDI is a professional digital video standard developed for broadcast video. SDI carries uncompressed digital video and 16 channels of PCM audio. SDI is transmitted over 75 Ohm coax cable with BNC connectors, typically RG-6.


There are 4 common SDI standards. The one will focus on is HD-SDI increased the supported resolution to 1080i/720p. 


HD-SDI and above can be run up to 300 feet. After 300 feet it can be reclocked and sent an additional 300 feet. If you need to carry high resolution uncompressed signal over long distances SDI is the way to go.


The downside to SDI is that, as a professional standard, many consumer and prosumer video devices do not natively support it. While Production Equipment typically offers SDI and HDMI solutions, many consumer-level products are moving toward sole HDMI solutions. 


HDMI Cabling

HDMI is a consumer digital video standard. HDMI offers high resolution output and the newest versions of the HDMI standard even allow for ethernet signal to be transmitted as well. Standard HDMI cables are capable of carrying resolutions up to 1080i/720p.


High Speed HDMI cables support 1080p up through 4K resolutions. The HDMI standards don’t place any limit on cable length, but like any other standard cable quality affects usable distance. Most commonly available cables are good for about 15 feet. Better quality cables are typically good for about 50 feet. Active cables, with signal boosters built in, can often carry clean signals for up to 100 feet. 


Many computers, video components, converters, and projects will accept HDMI. Some items to consider is that HDMI is not a lockable connector, like SDI and can  It can be a bit finicky for any or no reason.
