the second terminal displaying ticker information along with the displayed video based on the video data received from the first terminal such that the displayed ticker information displayed by the second terminal is inserted within the video displayed by the second terminal, the displayed ticker information displayed by the second terminal being based on the ticker information the second terminal received from the ticker device via the address identified in the first message.

2. The method of claim 1 , wherein the address at which ticker information from the ticker device is receivable is a uniform resource identifier that identifies a source of the ticker information.

3. The method of claim 1 comprising specifying a transmission protocol with a respective port through which the ticker information is transmitted in the parameters for transmission of ticker information included within the first message.

4. The method of claim 1 comprising specifying a payload type within the transmission parameters of the first message.

5. The method of claim 4 , comprising providing a standardized session description protocol for description and administration of the ticker information and at least one member of the group consisting of a standardized user data protocol, a transmission control protocol, a transport layer security protocol, a datagram transport layer security protocol, and a standardized real-time protocol for establishment of the multimedia data connection.

6. The method of claim 1 , comprising inserting at least one of formatting information and display information within the first message to define how to adjust the ticker information for displaying the ticker information for playback of the ticker information.

7. The method of claim 1 , comprising reconstructing the ticker information displayed by the second terminal for playing back the displayed ticker information.

8. The method of claim 1 wherein the ticker information that is displayed by the second terminal is inserted linearly as crawling information or in a specified area in one playback screen of the second terminal.

9. The method of claim 1 , wherein the establishing of the multimedia data connection between the first and second terminals such that ticker information from the ticker device is also sent to the second terminal when the multimedia data connection between the first and second terminals is formed occurs such that there is a first connection between the second terminal and the first terminal that is formed based on the transmission parameters for the multimedia data connection and a second connection between the second terminal and the ticker device that is formed based on the parameters for transmission of ticker information, the video data received by the second terminal from the first terminal being received via the first connection, the ticker information transmitted from the ticker device received by the second terminal being transmitted to the second terminal via the second connection.

10. The method of claim 1 wherein the multimedia data connection is a video-telephone communication connection.

11. A system for transmission and display of ticker information comprising:

a plurality of terminal devices connected to an enterprise system through a packet-oriented network, the terminal devices comprising a first terminal and a second terminal;

a ticker device connectable to the second terminal;

the first terminal generating a first message for signaling to the second terminal for an attempt to establish a multimedia data connection in which at least one of audio data and video data is to be transmitted from the first terminal to the second terminal, the first message generated in accordance with Session Initiation Protocol (SIP), the first message having data in accordance with Session Description Protocol (SDP) embedded therein that identifies transmission parameters for the multimedia data connection and also includes parameters for transmission of ticker information to the second terminal, the parameters for transmission of the ticker information comprising an address at which ticker information from the ticker device is receivable;

the second terminal receiving the first message;

in response to receiving the first message, the second terminal sends a second message to the first terminal that accepts establishment of the multimedia data connection;

in response to receiving the second message, the first terminal sending a third message to the second terminal to acknowledge receipt of the second message;

after sending of the third message, the first and second terminals establishing the multimedia data connection between the first and second terminals such that ticker information from the ticker device is also sent to the second terminal when the multimedia data connection between the first and second terminals is formed such that the second terminal receives audio data and video data from the first terminal and also receives ticker information from the ticker device for displaying ticker information along with displaying video during the established multimedia data connection, the video displayed by the second terminal being based on the video data received from the first terminal; and

the second terminal displaying the ticker information along with the displayed video based on the video data received from the first terminal such that the displayed ticker information displayed by the second terminal is inserted within the video displayed by the second terminal, the displayed ticker information displayed by the second terminal being based on the ticker information the second terminal receives from the ticker device.

12. The system of claim 11 wherein the address at which ticker information from the ticker device is receivable is a uniform resource identifier that indicates the address of a source of the ticker information.

13. The system of claim 12 wherein a transmission protocol with a respective port through which the ticker information is to be transmitted is within the parameters for transmission of ticker information included within the first message.

14. The system of claim 13 wherein a payload type is identified within the transmission parameters of the first message.

15. The system of claim 14 wherein at least one of formatting information and display information is within the first message to define how to adjust the ticker information for displaying the ticker information for playback of the ticker information.

16. The system of claim 15 wherein the second terminal reconstructing the ticker information displayed by the second terminal for playing back the displayed ticker information.

17. The system of claim 16 wherein the ticker information that is displayed by the second terminal is inserted linearly as crawling information.

18. The system of claim 11 wherein the establishing of the multimedia data connection between the first and second terminals such that ticker information from the ticker device is also sent to the second terminal when the multimedia data connection between the first and second terminals is formed is established such that there is a first connection between the second terminal and the first terminal that is formed based on the transmission parameters for the multimedia data connection and a second connection between the second terminal and the ticker device that is formed based on the parameters for transmission of ticker information, the video data received by the second terminal from the first terminal being received via the first connection, the ticker information transmitted from the ticker device received by the second terminal being transmitted to the second terminal via the second connection.

19. The system of claim 18 wherein the multimedia data connection is a video-telephone communication connection.

20. the system of claim 19 wherein each of the terminal devices is one of a telephone, a personal computer, and a computer device, and the enterprise system is a server.
