Abstract

The present invention relates to displaying caller ID information, and more specifically, to displaying caller ID information in an environment with broadband telephony service. The invention provides a method and apparatus for receiving caller ID information from a service provider and providing the caller ID information for display as an overlay over a television programming image provided by the service provider and displayed on a television.

Claims

1. A customer gateway for communicating with a service provider network, the service provider network providing television programming for display on a video device and telephony communications for supporting at least one telephone device, the customer gateway comprising:

a service provider network interface circuit for receiving IP frames from the service provider network, the frames comprising both television programming frames and telephony frames, the telephony frames including both VolP media session frames and signaling frames comprising caller ID data;

a telephony processing circuit including;

means for translating the VolP media session frames to telephone signals compliant with the at least one telephone device; and

means for providing the caller ID data to a television circuit; and

the television circuit comprising;

means for receiving the television programming frames from the network interface circuit and generating a television programming signal compliant with a receiver associated with the video device; and

means for receiving the caller ID data from the telephony processing circuit and overlaying the caller ID data on a portion of a video image represented by the television programming signal.

2. The customer gateway circuit of claim 1, wherein the means for translating the VolP media session frames to telephone signals comprises a PSTN circuit for generating a PSTN compliant telephone signal to each of a plurality of PSTN ports.

3. The customer gateway circuit of claim 2, wherein:

the means for providing the caller ID data comprises means for providing an identification of the at least one telephone device; and

the means for receiving and overlaying the caller ID data on a portion of the video image comprises means for receiving and overlaying the caller ID data and the identification of the at least one telephone device on the video image.

4. The customer gateway circuit of claim 1, wherein the means for translating VolP media session frames to telephone signals comprises a voice-over-IP circuit for maintaining a real-time communication channel with each of the at least one telephone device through a network port.

5. The customer gateway circuit of claim 4, wherein:

the means for providing the caller ID data comprises means for providing an identification of the at least one telephone device; and

the means for receiving and overlaying the caller ID data on a portion of the video image comprises means for receiving and overlaying the caller ID data and the identification of the at least one telephone device on the video image.

6. A method of processing caller ID data, comprising the steps of:

receiving frames from an IP service provider network, the IP frames comprising both television programming frames and telephony frames, the telephony frames including both VolP media session frames and signaling frames comprising caller ID data;

translating VolP media session frames to telephone signals compliant with the at least one telephone device; and

translating the caller ID data to an image representing the caller ID data;

translating the television programming frames to a television programming signal representing a television image for display on an associated video device; and

combining the image representing the caller ID data with the television programming signal such that the television image includes the image representing the caller ID data overlaid over a portion of the television image.

7. The method of claim 6, wherein the step of translating VolP media session frames to telephone signals further comprises translating the VolP media session frames to telephone PSTN compliant signals and coupling each PSTN compliant signal to one of a plurality of PSTN ports.

8. The method of claim 7, wherein the step of combining the image representing the caller ID data with the television programming signal further comprises combining an image of information representing with which of the plurality of PSTN ports the caller ID is associated.

9. The method of claim 6, wherein the step of translating VolP media session frames to telephone signals further comprises translating the VolP media session frames to frames compatible with a real-time communication channel over a frame switched network with each of a plurality of frame-switched telephone devices coupled thereto.

10. The method of claim 9, wherein the step of combining the image representing the caller ID data with the television programming signal further comprises combining an image of information representing with which of the plurality of frame-switched telephone devices caller ID is associated.
