Patent attributes
A system for displaying a graphical indication of a proximately located device is disclosed. When a mobile terminal (e.g., a mobile telephone) equipped with short-range communications (e.g., Bluetooth or wi-fi) as well as conventional long-range communications capabilities comes within range of set top box (e.g., a digital broadcast receiver), the set top box (STB) overlays an icon over the broadcast screen image indicating that a mobile terminal is present that can be used as a back channel to the cable operator. The overlaid icon may be presented in differing colors to indicate various characteristics of the mobile terminal, e.g., a type of the mobile terminal (phone vs. PDA) or a capability of the mobile terminal (e.g., ability to establish a GPRS or other data connection). A user of the STB can then use interactive services offered by the cable operator, and deliver interactive selections and commands to the cable operator via the mobile terminal back channel.
