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.

Content delivery to a digital TV using a low-power frequency converted RF signal

A method is provided for a system to display media contents from source devices on television channels of a television. The method includes receiving a channel change command from a remote control, where the channel change command causes the television to display a new television channel. The method further includes, in response to the channel change command, changing a frequency of a radio frequency (RF) carrier of a television RF signal to a frequency of the new television channel, determining one of the source devices assigned to the new television channel, and providing the television RF signal to the television, where the television RF signal includes a media content from the assigned source device.

Using TV remote control and TV to display content from any one of multiple sources

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 video content sources, such as a DVD player and cable/satellite box, may generate baseband signals in a variety of formats. The baseband signals are connected to a remote converter for converting the baseband signals to a low power RF transmission having a standard format typically received at the digital TV's RF input. The RF transmission has a range generally limited to within a home or room. The small antenna connected to the RF input of the digital TV will typically be located behind the TV so as not to be seen. The low power RF transmission is on a carrier frequency that is legally authorized by the FCC in frequency and power level.

In one embodiment of the invention, a conventional home computer is connected via the Internet to a link broadcasting computer that is being accessed by many other households. The link broadcasting computer receives the same television signals (including ATVEF signals or other datacast signals) received by the home televisions of the various users. The link broadcasting computer detects the ATVEF signals embedded in the vertical blanking interval of each television channel and communicates to each user's home computer only the ATVEF information for the particular television channel(s) previously identified by the user. The user can then access a website identified by the information. Various options are further described herein.
