1. A method for live streaming between mobile communication terminals, the method comprising:
- in response to a first mobile terminal entering a streaming mode, sending, at the first mobile terminal, a message including information with regard to an Internet Protocol (IP) address of the first mobile terminal and a first codec of the first mobile terminalto a second mobile terminal;
in response to receiving, at the first mobile terminal, a request message for access from the second mobile terminal, determining a third codec for encoding the audio and video data by the first mobile terminal, based on whether the request message includes information with regard to a second codec supported by the second mobile terminal,wherein determining the third codec comprises determining the third codec as the second codec when the request message includes the information with regard to the second codec,wherein determining the third codec comprises determining the third codec as the first codec when the request message does not include the information with regard to the second codec;
encoding, at the first mobile terminal, the audio and video (A/V) data generated from the first mobile terminal, using the third codec;
multiplexing, at the first mobile terminal, the encoded audio and video (A/V) data to generate Transport Stream (TS) data; and
transmitting, at the first mobile terminal, the generated TS data in a live streaming scheme to the second mobile terminal through the streaming channel via an Internet Protocol (IP) based packet service network.

Abstract
An apparatus and method support live streaming between mobile communication terminals. A server Mobile Station (MS) Transport Stream (TS)-multiplexes audio/video data, generates TS data, and transmits the generated TS data in a live streaming scheme to a client MS through an accessed IP based packet service network. A client MS receives the TS data generated by the server MS in the live streaming scheme through the accessed IP based packet service network, TS-demultiplexes the received TS data, and restores the original audio/video data.

5. A method for live streaming between mobile communication terminals, the method comprising:
-
receiving, at a second mobile terminal, a message including information with regard to an IP address of a first mobile terminal entered in a streaming mode, and a first codec of the first mobile terminal from the first mobile terminal; transmitting, at the second mobile terminal, a request message for access in which information with regard to a second codec is determined to be included based on whether the first codec is supported by the second mobile terminal; receiving Transport Stream (TS) data generated by the first mobile terminal, in a live streaming scheme from the first mobile terminal through the streaming channel via an accessed Internet Protocol (IP) based packet service network; and demultiplexing the received TS data and restoring original audio and video (A/V) data, using a third codec that is determined by the first mobile terminal. - View Dependent Claims (6, 7, 8, 9)

10. A mobile terminal for live streaming between mobile communication terminals, the first mobile terminal comprising:
-
a transceiver configured to; in response to the first mobile terminal entering a streaming mode, send a message including information with regard to an IP address of the first mobile terminal and a first codec of the first mobile terminal to a second mobile terminal; and in response to receiving a request message for access from the second mobile terminal, determine a third codec for encoding the audio and video data by the first mobile terminal based on whether the request for access includes information with regard to a second codec supported by the second mobile terminal, wherein the transceiver is configured to determine the third codec as the second codec when the request message includes the information with regard to second codec, wherein the transceiver is configured to determine the third codec as the first codec when the request message does not include the information with regard to the second codec; an audio and video codec configured to encode the audio and video (A/V) data generated from the first mobile terminal, using the third codec; a Transport Stream (TS) multiplexer configured to multiplex the encoded A/V data to generate TS data; and a processor configured to transmit the generated TS data in a live streaming scheme to the second mobile terminal through the streaming channel via an Internet Protocol (IP) based packet service network. - View Dependent Claims (11, 12, 13)

14. A mobile terminal for live streaming between mobile communication terminals, the second mobile terminal comprising:
-
a transceiver configured to; receive a message including information with regard to an IP address of first mobile terminal entered in a streaming mode, and a first codec for encoding audio and video data from the first mobile terminal; and transmit a request message for access in which information with regard to a second codec is determined to be included based on whether the first codec is supported by the second mobile terminal; a processor configured to receive Transport Stream (TS) data generated by the first mobile terminal in a live streaming scheme from the first mobile terminal through the streaming channel via an accessed Internet Protocol (IP) based packet service network; and a TS demultiplexer configured to demultiplex the received TS data and restore original audio and video (A/V) data, using a third codec that is determined by the first mobile terminal. - View Dependent Claims (15, 16, 17, 18)
