1. A transmitting device in a wireless audio/video (AV) system, the transmitting device comprising:
a memory;
a communication circuit forming a radio link; and
a processor for controlling the memory and the communication circuit, wherein the processor is configured to:
measure a Signal to Interference plus Noise Ratio (SINR) of the radio link;
select a Modulation and Coding Scheme (MCS) set based on the measured SINR;
select an optimal MCS from among the MCS set based on a priority of a signal; and
transmit the signal based on the optimal MCS,
wherein the priority of the signal is determined based on a Quality of Service (Qos),
wherein a signal with a high QoS is transmitted based on a first MCS,
wherein a signal with a low QoS is transmitted based on a second MCS,
wherein the first MCS is set to the lowest MCS among the MCS set, and
wherein the second MCS is set to a transmittable MCS in the radio link.
