Call progress information in cable telephony
View Patent ↗An apparatus for obtaining and displaying call progress information of a telephone call on the monitor of the television, including means for communicating control signals that flow in either direction between the apparatus and a set top box that controls the television.
1. Apparatus including a first port for connecting, through a junction to a cable head-end, and including a second port for connecting to a telephone, and a digital signal processor comprising:
a processing module that
receives, via the first port, an alert bursts sequence having at least one burst, the bursts indicating that connection to the telephone is sought by a remote party, and further receives call information following a first burst of the alert bursts,
performs an analysis of the call information,
sends, via the first port, a message toward the head-end when the analysis determines that the call progress information fails to meet a selected sufficiency level,
receives, via the first port, a responsive message that augments the call information; and
first transmission means for communicating the augmented call information to a controller in a set-top box.
2. The apparatus of claim 1 where the first transmission means is adapted to receive call progress directives from the set-top box, and the processing module is adapted to control progress of the connection pursuant to the directives.
3. The apparatus of claim 2 where the first transmission means comprises an interface module interposed between the processing module and the first port for communicating the augmented call information in a format that refrains from interfering with signals on the cable that are sent by the head-end over the cable to the television.
4. The apparatus of claim 1 further comprising a third port to which the first transmission means is connected, and which enables connection to the set-top box for effecting said communicating and said receiving.
5. The apparatus of claim 1 further comprising a set-top box having a first port for connecting to the cable, a port for connecting to a television, and a port for IR control signals, which set-top box comprises
a controller;
second transmission means for receiving the augmented call information from the first transmission means and for applying the augmented call information to the controller and for sending directives from the controller to the processing module via the first transmission means,
an IR receiver for accepting information from the IR port and forwarding the information to the controller,
a frame and sound generator responsive to the controller for developing frame and sound information, and
television receiving and displaying circuitry responsive to signals received from the cable, and the controller, and the frame and sound generator.
6. The apparatus of claim 5 where the frame and sound generator is responsive to control signals from said controller that are generated in response to the call information, or in response to commands received from the IR receiver, or both.
7. The apparatus of claim 6 where the sound frame and sound generator sends video frame information to the television receiving and displaying circuitry that results in the display of a curser on screen of a television connected to the port for connecting to a television.
