| 20120017248 | Content Delivery to a Digital TV Using a Low-Power Frequency Converted RF Signal - A simple antenna is connected to the RF input port on a conventional digital TV to receive video content from a plurality of video content sources wirelessly. The wireless RF transmission by a local transmitter has a range generally limited to within a home or room. The low power RF transmission is on a carrier frequency that is legally authorized by the FCC in frequency and power level. To identify the open channels for the RF transmission, a tuner scans for weak channels, and the transmitter is tuned to transmit on the detected weak channels. | 01-19-2012 |
