Coax to HDMI converter ONLY

by nishan421 / April 7, 2012 8:57 AM PDT

Hi, I was looking for a converter because I need one to make my TV channels look more hd and i searched everywhere, all that comes up is converters with coax and av cables to hdmi. I just want a small little converter that only has 1 coax port for input and 1 HDMI port for the out put. Please if anyone can find one like that it would mean so much to me. And under $50 because there is one that i found that has coax and av cables in the input with HDMI in the output. Thank you

I don't understand.

You want hdmi output; that tells me you have a hdtv (most likely). Doesn't this tv have a atsc (digital) tuner (it should)? Maybe your signal strength is not very strong. Converter is will not be much help in this case. We really need more information as to exactly what tv you have.

Coaxial to HDMI output

In reply to: I don't understand.

I have an LED TV that has an internal tuner. I also have an indoor antenna that captures the digital TV signals that are broadcast over the air which I can see fine on my TV with the exception of a couple of stations that have a weak signal and reception is based on meteorological conditions at the time (cloud=view; no cloud=too weak to watch)

In order to fix this problem I want to move the antenna to the second floor; the output cable is coaxial which I want to convert to HDMI which will then be plugged into a wireless transmitter; the wireless receiver will be by the TV and connected via HDMI cabling.

Contrary to some posts, the digital signal can be transmitted by coaxial cable specifically designed to do so (otherwise the signal from my digital antenna would not be carried to the TV) hence connecting the coaxial output from my digital antenna to an hdmi connector which is then plugged into a transmitter that can handle toe signal should work.

I am wondering where in Canada I can buy a coaxial to hdmi connector to complete the network.

You claim this is possible then ask for where to get such? Something's not right.

In closing, I own a Silicon Dust unit. You might like that.

Coax is an analog signal, as is the AV connector, HDMI is a fully digital signal. There is no such "cable" converter.

The odd part about the OP's post
by Pepe7 / April 8, 2012 1:38 PM PDT
In reply to: No such animal . . .

It appears as though he/she's making an attempt at improving the PQ of certain non-HD channels. We all know how non-HD channels can sometimes look bad, depending on the provider & feed. In this sense, there's nothing that will upscale that content properly to look like the HD feeds (clearly).

Don't forget that the cable signal coming into the house via a coax cable could be analog or digital, although truth be told, most areas have already switched to digital cable, with most channels still not broadcast in HD.

I am trying to convert coax to hdmi so i can get a better picture and i have a mix of digital and analog. My tv has a coax and a hdmi port and i want a better picture. Also if i convert it will the channels be HD?

Here are some converters with a lot of inputs, i just want coax as an input.

I want something like that but with coax as the only input not anything else. This also has coax as an input.

If that box works (which seems doubtful to me), I'd buy it. Why mind about the extra inputs?

It will not improve your picture. Take in proper context, convert simply means one connection into another so you can plug it into a specific device. It doesn't say anything in the specifications on the link you provided about upscaling channels or increasing PQ. That's where the rubber hits the road. A direct coax connection from your cable or satellite provider into your HDTV via a coax cable will suffice.

Or is the lack of inputs on your HDTV the crux of this matter?

I don't think that box will do what you are after.

If money is no object then here is a way you could do it. Get an external tuner and a video scaler; the antenna connect to the tuner, the tuner connect to the scaler, then the scaler connects to the TV. External tuner is not that expensive but the video scaler is very expensive. Personally I just learn to love my none-HD tv broadcast.

Try DVDO
by Pepe7 / April 13, 2012 5:28 AM PDT
In reply to: Links

It's about a half a grand, and is pretty decent for a consumer grade scaler IME. Example:
http://www.dvdo.com/

An external antenna/tuner to bring in OTA (=over the air) signals (some are in HD) would be easy enough as well, depending on where you live/proximity to the transmitter. Not sure about adding a scaler to that mix however. I havent' seen it personally, but technically is seems possible even w/ the DVDO consumer grade equipment if you read the spec sheets.

"High-speed HDMI cable is the only connection that can deliver a full HDTV experience with a full 1080p picture and digital surround sound."

from product from an LCD HDTV at best buy. and i think my uncle has a box to converter box

You missed some important points in this discussion

In reply to: here is what mean.

Keep in mind that I made a reference to a DVDO scaler. The OP *only* referred to making a 'regular channel look more like HD'. That's what you could use a scaler (or similar device) to accomplish. Read about scaler specifications so you can properly understand what's going on here.

Now, if he also was looking for surround sound, namely the expanded audio of blu ray codecs, etc., using HDMI would be the only way to go. Otherwise, if he only needed DD5.1 or DTS, a digital optical or digital coaxial connection could suffice, depending on the actual hardware he ended up with. Again, put these topics in perspective in this thread and we are good to go ;).

cheers

Be more detailed in what you are referring to, and perhaps we can have an actual discussion and figure out what is meant by all Wink

Sure coax can convert to HDMI
by triago_the_great / August 7, 2013 11:00 PM PDT
In reply to: No such animal . . .

There are tons of coax to HDMI converters. What do you think your cable box does? Unfortunately, they are expensive. Also, if your not getting an HD coax signal, then obviously the converter will do nothing. However, many channels provide free HD broadcast, like NBC, CBS, and the Food network. You can buy an HD antenna, run the coax through the HDMI converter, and bada bing.... HD TV

A little help please
by Mrandazzo55555 / September 21, 2013 1:50 PM PDT

Could you tell me if there is a way to take my RCA Selectivision recorder from Coax to HDMI? The picture from coax to coax is just horrible. Thanks in advance.

While how the cable box works is interesting, the topic is slightly different. Please start a new discussion if you want to dive into cable box tech.

Coax to HDMI Converter
by dcshifter / February 19, 2013 8:35 AM PST

This may be what anyone in this situation is looking for. $136 +/-

http://www.ambery.com/anvitodvcowi.html

Also if you have a DVD Player with tuner and proper connections, you may be able to use that to do the trick. Worth a try before spending money. Good luck! The units under $50 seem to be audio to HDMI.

Nope- cheap scalers stink, amigo
by Pepe7 / February 19, 2013 11:16 AM PST
In reply to: Coax to HDMI Converter

If you actually compare the results between a DVDO unit (see my above post), and cheap chinese crap like this, it's pretty easy to see why you should save your money.

Don't forget that many cable systems now encrypt, so the 'use the DVD player as an upconverter' trick is not much help either. Not that it looked any good anyway.
