[Closed] HDMI to WIFI? Is that possible (TV box to HDTV)

Just had Virgin installed and was able to obtain a free additional TiVo box for the bedroom. Problem is our TV is on the wall with hidden wires, and the box is on the other side of the room. Is there a solution to connect them wirelessly? The TV has a built in Wifi receiver. A bit of googling have found many wireless senders but the receivers need power. Cheers.

You'll struggle with a solution to this.

A chromecast and using the virgin media app if it supports casting might have been a better solution.

Would [url= http://www.keene.co.uk/av-distribution/av-over-distance/hdmi/wireless/marmitek-gigaview-811-wireless-hdmi-kit-3d-compatible.html ]THIS[/url] be the kind of thing you're looking for?
Edit. Did notice on the instruction PDF that you need power for the receiver........

HDCP could be your enemy.

And virgin TV anywhere won't work - it is locked to only the device's screen. Can't use MHL or casting or anything like that with it.

Do you have network cables in the wall? You can run HDMI over a cat5 cable with the appropriate converter.

Again, not sure how well these play with HDCP.

Google HDMI video sender. They're like a wifi box but specifically designed to convert HDMI to a radio signal. You can send HDMI signals over ethernet, but AFAIK its not actual TCP/IP traffic - the cables are just good at carrying it.

You might be able to power the receiver off a USB port (1.5a/5v)

Miracast/WiDi is the "standard" for HDMI over wireless, which is what those senders use. Let's just say a colleague was working on it and is now a bald alcoholic [1] so your mileage may vary. Stick to a single product and don't expect your laptop with a WiDi sticker to work and you might be pleased.

[1] Not entirely true

Thanks all, surprised to see there isn't something widely available with the onset of smart TVs. I guess my only other option will be a very very long hdmi cable but this will have to be at least 45 ft long. Would I still get a signal over that length?

As above this is a PITA I think. By far the best solution is to plug the device into the tv, ie the TiVo box. I don't have a lot of experience with smart TV / inbuilt wifi but everytime I have tried to access anything like live streaming it's not worked and even network drives / computers have been a bit of a pain.

One thought is if you can access the TiVo box from your phone you could possibly "cast" or Airplay that to the TV if the TV had a Apple TV/Chromecast. However I would also say these solutions can be "jumpy" especially if the Wifi signal is not strong in the bedroom

The HDMI specs don't specify a limit but rather a signal quality. The longer the cable run, the higher quality the cable needs to be. At that distance you're on the limits of what a certified cable is capable of, and it won't be cheap.

Why don't you move the Tivo box nearer the TV instead?

The other option, of course, would be to abandon HDMI and run something simpler like S-Video. Are you fussed about HD in the bedroom?

(not a euphemism)

HD not vitally important but the box only has scart and hdmi output. I could move the box over to the other side of the room nearer the TV but I would then have cables running up the wall, on the side of the room it sits now the cable could run up to the loft inside a built in wardrobe hidden. I'll prob have a look at some long hdmi cables and check out the specs.

Neet cables are pretty good.

You can also get a booster if you're going to put it somewhere out of the way

From memory scart will take an RGB signal to the appropriate connections that should give you reasonable quality up to 1080i?

Im sure you can get HDMI over powerline, so if you have a spare socket behind the tv and tivo box that would save you running wires.

Not usually anything above SD in a domestic device. Especially over SCART. You'd be stuck with SD.
