Definitions
- the present invention relates generally to the field of interactive television systems. More specifically, the present invention relates to a system and method for enabling communication between a user and a group of individuals at remote locations.
- television watching is an enormous popular pastime throughout the world. Indeed, one or more televisions can be found in virtually every residence in the United States and many foreign countries.
- the television viewing area is often the focal point of the home, a location at which family members spend a considerable amount of time, even when not watching television.
- a person wishes to make telephone calls while watching television.
- telephones and telephone directories are often located outside of the television viewing area.
- a person must often leave the proximity of the television to make or receive telephone calls. If the caller is watching a television program, he or she may miss a significant portion of the program by the time a telephone call has been placed or answered. This is particularly irksome if the caller wishes to discuss an ongoing television program with another individual over the telephone.
- a caller is often thwarted by others in the household who need the household telephone line for telephonic or Internet use.
- the caller If the caller does not know the telephone number of a person he or she wishes to contact, the caller must conventionally search voluminous telephone directories, scraps of paper, planners, personal desktop assistants (PDA's), and the like, for the number. This further reduces the caller's time for watching the television and diminishes the television viewing experience.
- PDA's personal desktop assistants
- either the caller or the intended recipient of the call may not have access to a conventional telephone line.
- many people are now using the Internet for telephonic communication.
- Internet-accessible telephonic connections do not operate with the same protocols as standard telephone numbers.
- an Internet-based telephone may use an IP (Internet Protocol) address instead of a telephone number.
- IP Internet Protocol

- the control may be embodied as a selectable menu item or the like within a graphical user interface (GUI) displayed by the interactive television system.
- GUI graphical user interface
- an indication of at least one group with which communication may be established is displayed.
- a user's selection of a particular group is then detected, after which two-way communication is established with each member of the selected group.
- two-way communication can be established by transmitting a communication request to a device associated with the network address of each member of the selected group, and opening, for each member accepting the request, a communication channel between the interactive television system and the corresponding device.
- the interactive television system includes a remote control, and a specifically-designated control on the remote control is associated with a group of individuals. Activation of the specifically-designated control is detected, and two-way communication is established between the interactive television system and the device belonging to each member of the selected group.
