Shenzhen Falco-Tech Corp has designed a small COFDM transmitter mostly useful for drones, unless you want to make you own very local TV station, that can transmit video from an HDMI camera such as GoPro Hero 4, and compatible with any DVB-T TV tuners as it sends the video unencrypted.

There’s no word about power consumption, so it’s unclear how it would impact fly time. I’m also not quite sure about the legality of the system in many countries, and/or you probably need to have a proper license to use DVB-T frequency band, and make sure you don’t disturb TV reception. Now anybody with a DVB-T tuner would be able to receive your video feed within the transmission range, and the company told me a version with encryption will be available in about 2 month time, but it will not be compatible with DVB-T capable TVs or set-top boxes.
I have not been told the price of the transmitter, but HawkEye I is listed for $1,000 on DIY Trade website.
