Convert Coax Cable to HDMI: If you purchase a new TV, chances are it won’t have a persuasive connector at the back. It may have lots of HDMI, USB and component connectors but no coax. If you have an older cable or satellite box that only outputs coax, you could have an issue connecting the two. That’s why to a TechJunkie reader last week which prompted this guide on how to convert coax to HDMI.
The reader bought a brand new 50” UHD TV thinking they had gotten the deal of the century and everything they wanted Until they found only HDMI and component connections on the back. They had an older satellite receiver in their drey that only outputs coax. So how do they join the two?
AV CONNECTION TYPES
While it may look obvious to some of you, not fully considering the output of the receiver is an easy oversight. For many years coax was the default output and has only recently been fully replaced by SCART or HDMI. Many satellite and cable receivers came with coax, SCART and HDMI. Some were purely coaxed.
Certainly, Coaxial cable was invented in the 19th century to carry radio signals. It is constituted of a copper core of two layers surrounded by shielding and insulation. The idea was to deliver analog signals with a minimum of interference. Until recently, the technology was in use first in radio and telegraphy, then TV and then broadband. It was gradually replaced with fiber or other technologies that offered faster transmission speeds.
Even though coax is insulated, the signal needs recurrent repeating and is subject to data loss over distance. Nowadays coax was popular because it was superior to anything else at the time, was cheap and easy to use. It was also very tough. Fiber is faster and carries large amount of data at once. Though fiber needs more upfront investment, it needs less maintenance.
HDMI stands for High-Definition Multimedia Interface. It is the modern replacement for coax in the home and used to carry signals between devices with the maximum amount of data possible for high definition. Not only this but also it can carry audio too. HDMI was invented by Japanese TV manufacturers to help improve picture quality and works exceptionally well.
HDMI is purely digital so therefore it is insulated against loss and does not need periodic repeating over distance. It can carry same size od data at higher speeds. Digital transmissions are resistant to interference when the correct configuration is used so it is very powerful and useful within busy households with lots of devices and WiFi networks.
CONVERT COAX CABLE TO HDMI
There are different ways. They ask their satellite provider to update their receive or they could buy a coax to HDMI converter.
While depending on the supplier, if the satellite receiver has only a coax output, it is due for replacement. Except for SCART or any HDMI output means it could be anything up to 25 years old and should be replaced. However, if it is working good or your service provider wishes to charge you for an upgrade it might not be your best choice.
COAX TO HDMI CONVERTER
Coax to HDMI converters usually come as an adapter. Those having larger AV setups may need a more involved convertor unit but for the rest of us, a simple coax to HDMI converter box will suffice. Other retailers offer the same kinds of products too.
The converter takes the analog signal and converts it into a digital signal for HDMI. Either it comes with cables attached or has sockets for each cable at either end. Some converters perform a straight conversion, the signal for a signal. Others include scaling that takes a standard definition coax signal and convert it into a high definition digital signal. Which one you select depends on your needs.
Connecting the TV to the satellite receiver is very straightforward. You can take the coaxial output from the satellite receiver and connect it to the coax input on the converter. You can take the HDMI feed from the converter and attach it to an HDMI input on your TV. Now you should be able to set the satellite receiver as a source and watch TV.
Converting coax to HDMI is not difficult but requires a little extra investment. If you’re in a similar situation there is a way around it and it won’t cost as much as you might think.
