communications capabilities comes within range of set top box (e.g., a digital broadcastreceiver), the set top box (STB) overlays an icon over the broadcast screen imageindicating that a mobile terminal is present that can be used as a back channel to thecable operator. The overlaid icon may be presented in differing colors to indicate variouscharacteristics 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 dataconnection). A user of the STB can then use interactive services offered by the cableoperator, and deliver interactive selections and commands to the cable operator via themobile terminal back channel.
