Input HDMI from Roku 3 - Output Coaxial (both audio and video) to an older TV

No. The coaxial output is only digital audio. All the video goes out the HDMI output. I have found that some video sources only send the 5.1 Dolby audio out the HDMI (or possibly the optical output) unless it is changed to 2 channel stereo. For example, I have a Blue Ray video and playing it on my Sony BD player, only the background audio that is not in the selected language goes out the Coax port. The language audio (i.e. all the talking) goes mute unless I change this switcher into 2 channel stereo mode. Then the audio comes out the coax. Without doing this, the only audio heard is the sound effects like shoes walking, engine noises, etc. with no talking. I don't like that. I lose the 5.1 Dolby Surround for these videos.

Yes...why not?...It has a Coaxial and Optical output and the HDMI for your TV or Components

Looks like the Roku has an HDMI out, in which case no, this is for analog only, specifically composite (yellow/red/white, not component)

The previous answer is basically correct. The 3 RCA cable connections are analog and the HDMI is digital so, this cable (or any other) will simply adapt from one type of connector to another but will not convert from one signal type to another. For that, you will need to purchase a converter. I would also check your ATT converter box to see if it does in fact have an analog output. I don't know about ATT but Cox, DirecTV and most other providers boxes provide several output so people with older TV's don't have to go buy a new TV. Hope this helps.

Yes, it turns the coax cable into rca, s-video, or vga (and 3.5mm for audio)

yes it will because it has not only HDMI outlet but also component TV outlet ( red white and yellow connectors ) if your TV is really really old and has only the antenna IN connection in that case just get a modulator ( less than 15$) to connect Roku to Antenna IN in your TV with component. see here http://www.ebay.com/itm/Philips-PH61159-RF-Modulator-Video-Converter-with-S-VIDEO-INPUT-/261066772715

I am sorry, that's Is impossible. You cannot convert HDMI to coaxial with this box. As a matter fact I can't think of any other box that will do that for you. Sorry.You could convert HDMI to composite .

It comes with RCAs also My tv is so old that my Roku is on RCA also and I need a splitter to use both

We're going Roku to TV with HDMI, then TV out to receiver/stereo with RCA and that works; but no way to go direct from Roku 2 to receiver with RCA

My house is wired in coax and i broke the coax connection on the back of one of my TV's. But it also has a hdmi connection as well and have been trying to convert from coax to hdmi . I have been told there currently is no solution.

This will take an RCA video audio signal input (yellow, red, white cables) and convert it to a coax cable output ( single cable with screw on head). Coax cable is the standard input to a TV when using an antenna so every TV will have that type of input.

only one channel HDMI from the box or antenna to tv creating transfer of regular signal to creative 3D old style

Take the HDMI out of the Roku to the input on the extractor. Then the HDMI output from the extractor to the TV or AV Receiver. Next choose analog or digital audio output from extractor and connect that output to the audio device. Depending on connections you may require extra cables such as HDMI, Toslink, Stereo RCA Audio.

You should not need this device. Just run an HDMI cable from roku to TV. HDMI carries both video and audio.

You need to buy a powered switch that has 2 inputs and 1 output. Cable and roku go to input, and output goes to Tv

This 3 ft. HDMI cable will work fine to connect your Roku to your HDTV. The short length leaves less extra cable bunched up behind the TV.

You can connect anything with an HDMI output and hook up to your older television as long as it has "component video input."
