How to get video to a TV that only has analog RF coax input?
Posted by: Winston
Date: May 12, 2019 08:44PM
We have a commercial treadmill we got used. It has a 15" LCD that can be used as a TV. The input is a coax cable with a tuner that I think only handles analog RF channels.

The TV also has a 30 PIN iPod/iPhone connector, with the ability to handle "iPod video".

Sadly, no HDMI.

Ideally, I'd like to be able to connect an iPhone to it and play any video that the iPhone can do, including things like Netflix and Amazon Prime Video.
Anyone know of a way to do this? Guessing that the content controls in HDMI will severely limit what we can do.

We do not have cable TV, but do have a rooftop antenna, and could also connect a digital to analog TV tuner to it.


The LCD also has an ethernet input, but I'm not sure what that enables. Found some references to it handling "IPTV". Trying to find out more.


Thanks.

Quick read on the lightning to 30 pin adapter. No video support.
Other options are to replace the LCD to a more modern one that takes HDMI.

Hacking involved: The HP L1530 with DVI is a possible donor screen replacement.
Fastest / easiest option is a used tablet.

Easy enough to find a digital TV tuner with analog output on Amazon.

Alternatively, can get an HDMI to analog converter box with coax output.

Cheapest way? Find an old VCR with RF in/out and RCA In/Out. Connect the RF from the VHS to TV, set the input on the VHS to RCA or Aux, and connect your input that way. You'll still need something to go to the RCA in on the VHS. Most satellite/cable tuners have that. The VCR is only a bridge.

probably the best and most elegant solutions. Spending money on some adapter is a waste of time. get a cheap kindle. it will probably have better support than some mingxhuawei cheap tablet (just a brand name made up, but I would not be surprised it it was a real brand, LOL)

Winston, PM me as I have a 19" Sharp in box that I used in the kitchen and at least one LG that I will check out in the morning. Very clean and working. Spec's when you ask. Wife says get rid of them. I have replaced them with larger units.

It's a bit more complicated than that. The treadmill has a 15" touch screen LCD which controls most of its functions. The manufacturer calls it the "console". The console is essentially a lightweight Windows computer (was there a Windows CE?). The inside looks like a computer motherboard, with various sub-boards like the TV tuner and ethernet connection.

We've tried an Apple Lightning to 30 pin cable. Audio works. The treadmill's touch screen display has iPod support, but the standards are old enough that the touch-screen iPod controls don't work. Video does not work.

I've got an email in to the treadmill's manufacturer to see if there are any upgrades available.
However, I'm guessing that there will not be upgrades available. It's also not likely that there is a newer console available, for both physical mounting reasons, and because the console interacts with separate electronics in the treadmill's base.

Thanks. My first thought as well. (Well, second thought - iPhone was first.) We have an OTA antenna wired to cable jacks around the house, and already have three older TVs running from digital TV tuners. Pretty sure that will work.

I looked at HDMI to analog converters, but my son notes that it's likely none of them support protected content from Netflix, Amazon Prime, etc.

I've been asking around to see if there are any boxes which combine a digital TV tuner and an HDMI input for output to analog RF coax, but so far haven't gotten a definitive answer. It appears likely not. The digital TV tuners which have HDMI use it for output, not input.

Would block the touch-screen LCD which controls the treadmill.

There is a sort of book stand below the LCD, so we could use a tablet. However, with a variety of people in the family using the treadmill, it would be easier if we could let each person use their own iPhone with the existing LCD.

ps: I also note that the touchscreen on the console is quite robust, and designed to work when someone is hot and sweaty. A tablet likely would not be as user friendly on the treadmill.

Cheapest way? Find an old VCR with RF in/out and RCA In/Out. Connect the RF from the VHS to TV, set the input on the VHS to RCA or Aux, and connect your input that way. You'll still need something to go to the RCA in on the VHS. Most satellite/cable tuners have that. The VCR is only a bridge.


We don't have cable or satellite TV. We have Netflix, Amazon Prime, and YouTube TV. All of these are available via an HDMI connection from a variety of devices, but the LCD doesn't have an HCMI input. I'm pretty sure any VCR with HDMI input would be subject to the content-control aspects of HDMI, and would not forward the signal to analog TV, even if it had the ability to convert digital to analog.

Thanks. That might work. Let me think about it. The basement room the treadmill is in got wet, and is currently in disarray. (We had to pull up the flooring, and nothings in the right place.) The treadmill faces closer to the wall than it normally does. I'm sure I could rig up a mount for a 19" LCD TV on the treadmill itself, if putting it on the wall puts it too far away.

Also, we have an elliptical and a stationary bike in the same room. If I decide to go for a TV in the room, I might want to rig something up that all three could use. (This has not been practical in the past as the three machines didn't face in the same direction.)

If you are really wanting to stream, then...this has RCA out-->VCR-->RF out

But otherwise, I'd just tape a cheap tablet to the contraption!

Will take a look at the Roku. Thanks!

Can't tape a tablet to it, as it would block the touchscreen (which controls the treadmill). But maybe could use velcro so it could be moved. Still, something of a hassle to move the tablet, while running, to adjust the controls. Probably would be better to set up a TV.


Thanks.

ps: Turns out my son has an older Roku box which has A/V out. I might also have an RF Modulator (A/V to RF) somewhere, if not, they are about $13 on Amazon.
