Telus TV HDMI over cat6 using adapters

[wireless]

I have cat 6 wire run in the walls of my home between my TV(Sony) and my Telus TV box. I have been told that I can use an HDMI to RJ45 adapter. I have purchased one through Amazon(GEATSTAR 30M HDMI to RJ45 Network Cable Extender Converter Adapter). The picture flashes very briefly and then I get an error message. I have tried this direct from the Telus box to the TV using a cat6 patch cable as well as on a second Telus box and different brand of TV(Samsung). I get the same error message. There are other adapters on the market, but before I spend more money I'd like to know if this is technically possible. Do any of you have any knowledge of transmitting HDMI over CAT5e/6 wiring? Thanks,dave49.
