1. A method of transmitting and receiving data by a transmitter terminal, the method comprising:
- transmitting first data to a plurality of receiver terminals connected to a transmitter terminal;
receiving a plurality of feedback information from the plurality of receiver terminals;
determining first data loss rates based on the plurality of feedback information;
selecting a maximum data loss rate and a minimum data loss rate among the first data loss rates;
determining a second data loss rate based on a difference between the maximum data loss rate and the minimum data loss rate;
determining a transmission speed of second data based on the second data loss rate; and
transmitting the second data to the plurality of receiver terminals according to the determined transmission speed.

Abstract
A method of and an apparatus for transmitting first data to a plurality of receiver terminals connected to a transmitter terminal through the transmitter terminal and transmitting second data to the plurality of receiver terminals through the transmitter terminal is performed according to a transmission speed determined based on at least one selected from feedback information of a receiver terminal selected based on a data loss rate of the first data and variation information of data stored in a buffer of the transmitter terminal.
