1. An Audio/Video (A/V) transmitting device comprising:
a Radio Frequency (RF) transmitting module configured to transmit a compressed RF packet to an RF receiving module of an A/V receiving device, the RF transmitting module including a plurality of transmitting antennas; and
a processor configured to obtain radio performance between the RF transmitting module and the RF receiving module and, when the obtained radio performance satisfies a preset radio performance, sequentially turn off one or more transmitting antennas among the plurality of transmitting antennas,
wherein the obtained radio performance includes a Received Signal Strength Indicator, RSSI,
wherein the processor is configured to turn off a first transmitting antenna among the plurality of transmitting antennas and obtain a second radio performance and, when the obtained second radio performance satisfies the preset radio performance, to turn off a second transmitting antenna among the plurality of transmitting antennas.
