1. An electronic device comprising:
a memory;
a processor; and
a communication interface configured to transmit audio packets to at least one sink device,
wherein the processor is configured to:
determine bit rates of the audio packets based on a type of each of the audio packets, wherein the audio packets include a main packet and retransmission packets;
encode the audio packets including the main packet and the retransmission packets based on the bit rates of the audio packets; and
repeatedly transmit the audio packets including the main packet and the retransmission packets a predetermined number of times to the at least one sink device through a broadcasting channel,
wherein the processor is further configured to allocate a bit rate of a plurality of different bit rates to an audio packet of the audio packets based on a type of the audio packet, the type of the audio packet being the main packet among the audio packets or a retransmission packet of the retransmission packets among the audio packets, wherein the main packet is a packet which is to be transmitted first among the audio packets and the retransmission packet is a packet of the retransmission packets which is to be transmitted later than the main packet among the audio packets.
