ABSTRACT:
An improved methodology and implementing system are provided in which a docking station is arranged to receive and dock a number of individual wireless personal information management (IM) units. In an exemplary embodiment, the personal IM units include touch-sensitive flat display screens. One or more of the personal wireless IM units may be individually removed from the docking station and operated to selectively and individually communicate with the docking station to access and retrieve more detailed information related to a presentation being made in another medium such as a TV or even an associated live presentation. In one example, the docking station is arranged to receive input from a TV system relative to which channel is being presented on the TV and is enabled to access and retrieve detailed information from a server which is related to the content of the current TV presentation. Alternatively, a user may select to use the personal IM unit independently of the TV to access selected unrelated web sites or to retrieve information from a server concerning a past or scheduled future TV presentation. The docking station includes means for determining which of a number of personal IM units is front-most in the docking station. The server is generally programmed ahead of time with detailed information related to scheduled TV programs and may also be coupled to a TV station directly to dynamically provide additional content for unscheduled TV programs.
