Unless you are using HDMI this is redundant
HDMI CONVERTER TO RCA WALMART NEAR ME TV
The ARC service on your new TV assumes it is going on into a HDMI input ,and has the ability to automatically switch it on and off if the TV is switched on. It doesn’t need to demodulate because it connects directly to the TV and uses channel 3 or 4.Many others of us here are also dinasours also. If you want more confusion, an HDTV with “coax in” receives the modulated cable box signal and decrypts it but still leaves it modulated. Just set the channel to 3 or 4 on the demodulator box so it can receive the cable box signal. The demodulation occurs just before the HDMI out because its tuner needs modulation to use channel 3 or 4 to receive the cable signal. Ī demodulator (the $115 one) takes in the cable box’s modulated signal (coax) and demodulates it for HDMI out. Why? The item listed below is designed to receive over-the-air (OTA) coax signals that are “unencrypted” whereas cable uses an encrypted signal. This item below may only cost around $30, but it won’t work, so don’t waste your money. You cannot send RF modulation through HDMI. The reason you need demodulation is that you require an already-converted and decrypted A/V out that passes to the HDMI. What you need is a demodulator (coax demodulator to HDMI.) The item below is around $115. Now, you can get an HDMI to coax adapter if you need to go from an HDMI out to a TV with coax input, but the other way is rather challenging. The problem is that the coax uses radio-frequency modulation (RF Coax), just like the old-school RCA to coax converters that required channel 3 or 4 on your TV set. That scenario means you need one of the same $100+ converters used for cable TV coax to HDMI. However, it needs a demodulator to convert the RF signal to HDMI out. Therefore, you need an RCA or NTSC coax-to-HDMI converter. VCRs and older game consoles did not use HDMI outputs because they didn’t exist. Just look for a cable TV coax demodulator to HDMI converter.
This type of coax to HDMI converter is hard to find, especially with all the similar options out there that don’t work for your needs. Therefore, the converter must have decryption technology too. Also, cable boxes and satellite dishes use encrypted signals that pass through the coax. Coax TV signals use radio frequency (RF) modulation that outputs to channel 3 or 4 on your TV. The satellite or cable TV coax-to-HDMI converter must include demodulation, which brings the price up to over $100. However, if it is working fine or your service provider wants to charge you for an upgrade, it might not be your best option. Not including SCART or any HDMI output means your satellite/cable box could be anything up to 25 years old and should be replaced. You may also need a converter if the RCA outputs on your satellite or cable box failed. Satellite/Cable TV Box Coax to HDMI Converters Source: ĭepending on your cable provider, if the receiver has only a coax output, it is due for replacement. The price is low because no major conversion components are required since air signals are not encrypted like cable TV. Over-the-Air (OTA) to HDMI Converters Source: įor those of you who have indoor/outdoor antennas with coax and no coax input on your TV, you need a simple OTA coax to HDMI adapter, which costs anywhere between $30-$50. Digital transmissions are immune to interference when the correct configuration is used so it is very useful in busy households with lots of devices and WiFi networks.ġ. It can carry more data further for the same size at higher speeds. HDMI is purely digital and is therefore insulated against loss and does not need frequent repeating over distance. HDMI was invented by Japanese TV manufacturers to help improve picture quality and works exceptionally well. It is used to carry signals between devices with the maximum amount of data possible for high definition or ultra-high-definition broadcasts. HDMI, or High-Definition Multimedia Interface is the modern replacement for coax in the home. Though fiber requires more upfront investment, it requires less maintenance. Fiber is faster and can carry more data at once. Coax was popular because it was superior to anything else at the time, was cheap and easy to use.
Even though coax is insulated, the signal needs frequent repeating and is subject to data loss over distance.
