Invention Disclosure:

Present IR remote controllers do not support video, and hence video previews of different channels must be done using PIP on the main TV's display. In addition, lack of a video display prevents these remote controls from being used to interact with the EPG in more complex ways using a touch-screen or stylus.
Others have addressed these issues.  There are "wireless TV's" available on the market now from Sony (LocationFree) and Sharp (Aquos Wireless TV) that provide a "wireless transmitter" box that transmits video to a "wireless receiver" located in the home. However these do not provide "remote controller" functionality. For example the Sharp is too large and both the Sharp and Sony models are made for inter-room communication, and cannot control video on the primary TV in the home. In addition, both use 802.11x wireless technology that is susceptible to RF interference from other devices.

There is more than one way to use this device.  For example, instead of having a direct IR link from the mobile unit to the display, it is possible to transmit the "IR" commands via RF to the base unit, and then transmit the "IR" commands from the base unit to the display via an IR-blaster located next to the IR sensor on the display. In this case the link between base unit and IR blaster can be wired or wireless.

The advanced video-remote controller (ARC) accessory is described.

The ARC consists of a base unit and a mobile unit (FIG. 1). The base unit has input connectors for cable TV, DSL, DVD, etc. The base unit has an output connector (usually coax) to the main TV. The base unit also has a wireless RF UWB transmitter and receiver, that communicates with the mobile unit.

The mobile unit has a UWB transmitter and receiver to communicate with the base unit. The mobile unit also has a display for video, web content, text, etc. This display is ideally touch-screen enhanced....
