Signal processing apparatus, audio apparatus, and method of controlling the same

An audio apparatus comprising:

• a transceiver which communicates with a signal processing apparatus;
• a speaker unit which processes and outputs audio data;
• and
• a central processing unit which prepares for output of the audio data upon receiving a command from the signal processing apparatus, to prepare for output of the audio data, and controls the transceiver to inform the signal processing apparatus of a completion of the preparing of output of the audio data and then to receive the audio data transmitted by the signal processing apparatus, and controls the speaker unit to output the received audio data upon the completion of the preparing of output of the audio data.

A control method of an audio apparatus, comprising:

• preparing for an output of audio data upon receiving a command from the signal processing apparatus to prepare for output of the audio data;
• upon completing the preparing for the output of the audio data, informing the signal processing apparatus of the completing the preparing for the output of the audio data;
• and
• receiving the audio data transmitted by the signal processing apparatus and outputting the received audio data.

A control method of switching at least one of audio and video output, the method comprising:

• receiving a first signal for switching an output of the at least one of audio and video from a first device to a second device;
• transmitting a second signal based on the first signal, to the second device, to set the second device to output the at least one of audio and video;
• and
• switching the output of the at least one of audio and video from the first device to the second device when the second device is set to output the at least one of the audio and video.
