Abstract: A method for transmitting video data in a video telephony system includes generating an intra frame at a first interval, transmitting the intra frame to a receiving terminal, and generating the intra frame at a second interval if data transmission with the receiving terminal is possible. The first interval may be shorter than the second interval.

Abstract: A method for reducing a risk of a call connection failure in a video communication providing a multimedia ring back tone service includes replying to a call connection request from a calling terminal, receiving a first message, determining whether the first message includes predetermined data and if the first message includes the predetermined data, setting a second message from the calling terminal as an initial value for a Numbered Simple Retransmission Protocol (NSRP) session with the calling terminal. The predetermined data may include a video temporal spatial tradeoff command, miscellaneous video temporal spatial indication, or a video fast update picture command. A system to perform the method includes a receiving unit, a determination unit, and a setting unit.
