First Claim
Patent Images
1. A method of transmitting and receiving data through a transmitter terminal, the method comprising:
- transmitting first data to a plurality of receiver terminals connected to a transmitter terminal;
determining a transmission speed of second data based on at least one selected from feedback information of a first receiver terminal selected from the plurality of receiver terminals based on a data loss rate of the first data and variation information of data stored in a buffer of the transmitter terminal; and
transmitting the second data to the plurality of receiver terminals according to the determined transmission speed.
