Re. Option 1 - In the days of analog TV broadcasting, inexpensive modulators were common. You could take video and audio from any source and transmit it on an RF carrier into your cable system. Virtually every VCR had a modulator built in. So far, no consumer grade digital (ATSC/8VSB) modulators have come to market (Please, anyone, prove me wrong!). If an inexpensive ATSC modulator were available, you could re-broadcast the received data on your private cable system on channels that don't conflict with each other.

Generally, you need a PC at the TV to process the data from a tuner (internal or external to the PC, not the tuner in the TV) or file server. An increasing number of TVs have an Ethernet interface and browser software for web surfing, social media and perhaps streaming services such as Youtube, NetFlix, Hulu, etc. But I have yet to see any provide the software needed to directly display raw OTA data (formatted as an MPEG-2 stream, which is what comes out of the SiliconDust HDHR tuner or copy of same on disk) unless it arrives at the TV in the traditional OTA RF signal, through the TV's tuner.

The SiliconDust HDHR-Tech model (about $300 US / each) can stream to an unlimited number of destinations by using IP Multicast. Each recipient would still require a PC or equivalent hardware interface between the Internet/LAN Ethernet and HDMI port of the TV. You would need one HDHR-Tech for every two channels (the basic HDHR models have two independent tuners).



Re. Option 2 - The short answer is yes. tinlee.com is one of the few remaining vendors that cater to this sort of OTA television reception need at a price point somewhere between consumer and commercial/industrial. You may want to contact them to get an idea of what their approach to your 'want list' would look like.
