Abstract
An audio processing apparatus according to embodiments comprises: a memory for storing audio data; a radio frequency (RF) unit for wirelessly transmitting a signal that includes the audio data, and wirelessly receiving a signal that includes information indicating a normal connection; and a processor for controlling the memory and the RF unit, wherein the processor can transmit the audio data stored in the memory to one or more speakers through the RF unit, and control the RF unit so that the audio data is retransmitted if information indicating a normal connection cannot be received from at least one speaker from among the one or more speakers.
Claims8
An audio processing apparatus comprising:
- a radio frequency (RF) unit configured to wirelessly transmit a signal including audio data and wirelessly receive a signal including information indicating a normal connection;
- a memory configured to store the audio data;
- and
- a processor configured to control the memory and the RF unit,
- wherein the processor is configured to:
- control the RF unit to transmit the audio data stored in the memory to one or more speakers;
- control the RF unit to retransmit the audio data based on a failure to receive the information indicating the normal connection from at least one speaker among the one or more speakers;
- check a number of times that the audio data is retransmitted;
- retransmit the audio data based on that the number of times of retransmission is smaller than a maximum number of times of transmission;
- and
- transmit a null data frame to the at least one speaker in an abnormal connection state based on that the number of times of retransmission is equal to the maximum number of times of transmission, and
- wherein the null data frame is generated based on a lowest modulation and coding scheme (MCS).
An audio processing method comprising:
- generating audio data, wherein the audio data is stored in a memory;
- transmitting a signal including the audio data wirelessly through a radio frequency (RF) unit;
- receiving a signal including information indicating a normal connection wirelessly through the RF unit;
- transmitting the audio data stored in the memory to one or more speakers through the RF unit;
- based on a failure to receive the information indicating the normal connection from at least one speaker among the one or more speakers, retransmitting the audio data;
- checking a number of times that the audio data is retransmitted;
- retransmitting the audio data based on that the number of times of retransmission is smaller than a maximum number of times of transmission;
- and
- transmitting a null data frame to the at least one speaker in an abnormal connection state based on that the number of times of retransmission is equal to the maximum number of times of transmission, and
- wherein the null data frame is generated based on a lowest modulation and coding scheme (MCS).
