Abstract

Teletext for video telephony between subscribers conferencing over a telecommunications network is provided. A Gatekeeper controls communications of the telecommunications network. A video encoder/decoder encodes and decodes audio/video signals to provide video telephony to at least one subscriber. A video text server provides teletext signals representing teletext to be established in the video telephony conference. The video encoder/decoder originates a SETUP message to the Gatekeeper. The Gatekeeper includes address translation rule that causes the Gatekeeper to redirect the SETUP message to the video text server. The videotext server sends a Release Complete message to the Gatekeeper. The teletext signals representing the teletext are rerouted from the video text server to the Gatekeeper.

Claims

1. A method for establishing teletext for a video telephony conference between subscribers conferencing over a telecommunications network whose communications are controlled by a Gatekeeper, a video encoder/decoder encodes and decodes audio/video signals to provide the video telephony to at least one subscriber, and a video text server provides teletext signals representing teletext to be established in the video telephony conference, comprising the steps of:

originating by the video encoder/decoder a SETUP message to the Gatekeeper;

inserting an address translation rule in the Gatekeeper that causes the Gatekeeper to redirect the SETUP message to the video text server;

sending by the videotext server a Release Complete message to the Gatekeeper; and

rerouting the teletext from the video text server the teletext signals representing the teletext to the Gatekeeper.

2. The method according to claim 1, further comprising the step of sending by the Gatekeeper the teletext signals to the video encoder/decoder.

3. The method according to claim 1, further comprising the step of sending by the Gatekeeper a notification to the end-user that the service is activated.

4. The method according to claim 1, further comprising the step of including in the SETUP message an E.164 number of the at least one subscriber that receives the video telephony.

5. The method according to claim 1, further comprising the step of selecting by the user the teletext for video telephony option a service representing delivery of content media to the at least one subscriber.

6. The method according to claim 5, further comprising the step of providing the at least one subscriber with an interface on the video encoder/decoder that allows the at least one subscriber to select a type of content media to be received.

7. The method according to claim 6, further comprising the step of including in the SETUP message the email address of the at least one subscriber that receives the video telephony and redirecting the content media to the email address.

8. The method according to claim 6, further comprising the step of including in the SETUP message a short message service (sms) number of the at least one subscriber that receives the video telephony.

9. The method according to claim 6, wherein the content media is one of the group consisting of news, sports, financial information, entertainment listings, holiday adverts, cinema, music, TV reviews, back-up information for TV programs, and themed magazines.

10. A system for establishing teletext for a video telephony conference between subscribers conferencing over a telecommunications network, comprising:

a Gatekeeper for controlling communications of the telecommunications network;

a video encoder/decoder for encoding and decoding audio/video signals to provide video telephony to at least one subscriber; and

a video text server for providing teletext signals representing teletext to be established in the video telephony conference,

wherein the video encoder/decoder originates a SETUP message to the Gatekeeper,

wherein the Gatekeeper includes address translation rule that causes the Gatekeeper to redirect the SETUP message to the video text server,

wherein the videotext server sends a Release Complete message to the Gatekeeper, and

wherein the teletext signals representing the teletext are rerouted from the video text server to the Gatekeeper.

11. The system according to claim 10, wherein the Gatekeeper sends the teletext signals to the video encoder/decoder.

12. The system according to claim 10, wherein the video encoder/decoder is a STB.

13. The system according to claim 10, further comprising a digital subscriber line (DSL) for connecting the video encoder/decoder to the Gatekeeper.

14. The system according to claim 10, wherein the at least one subscriber selects the teletext for video telephony option as a service representing delivery of content media to the at least one subscriber.

15. The system according to claim 14, further comprising a user interface on the video encoder/decoder that allows the at least one subscriber to select a type of content media to be received.

16. The system according to claim 15, wherein the video/encoder decoder includes in the SETUP message the email address of the at least one subscriber that receives the video telephony and redirecting the content media to the email address.

17. The system according to claim 15, wherein the video/encoder decoder includes in the SETUP message an short message service (sms) number of the at least one subscriber that receives the video telephony.

18. The system according to claim 15, wherein the content media is one of the group consisting of news, sports, financial information, entertainment listings, holiday adverts, cinema, music, TV reviews, back-up information for TV programs, and themed magazines.
