Electronic apparatus and a method of controlling the same

An electronic apparatus, comprising:

• a storage to store an operating system;
• a controller to boot the electronic apparatus using the operating system stored in the storage;
• a speaker to output sound;
• a communication interface to receive sound data from an external apparatus;
• and
• a sound processor to process and output the received sound data through the speaker,
• wherein the communication interface, the sound processor, and the speaker operate even when the electronic apparatus is not booted, and
• wherein the communication interface comprises:
• a first Bluetooth communicator to operate only when the electronic apparatus is booted, and to exchange data with the external apparatus using a Bluetooth method;
• and
• a second Bluetooth communicator to receive sound data from the external apparatus using a Bluetooth method and transmit the received sound data to the sound processor using an analog method.

An electronic apparatus comprising:

• a speaker to output sound data as sound;
• and
• a communication interface to be in a state to, when the electronic apparatus is in a power-off state, receive sound data from an external apparatus and transmit the received sound data to a sound processor which processes the sound data such that the speaker outputs the processed sound data as sound when the electronic apparatus is in the power-off state,
• wherein the communication interface comprises:
• a Bluetooth communicator to receive sound data using a Bluetooth method;
• and
• wherein, when the electronic apparatus is booted, the Bluetooth communicator transmits the received sound data to the sound processor using a digital method, and when the electronic apparatus is not booted, transmits the received sound data to the sound processor using an analog method.

A method of controlling an electronic apparatus, the method comprising:

• receiving sound data from an external apparatus using a Bluetooth method;
• transmitting the received sound data to a sound processor;
• processing the received sound data;
• and
• outputting the processed sound data as sound from a speaker of the electronic apparatus such that the receiving and outputting are performed when the electronic apparatus is in a power-off state,
• wherein, when the electronic apparatus is booted, the received sound data is transmitted to the sound processor using a digital method, and when the electronic apparatus is not booted, the received sound data is transmitted to the sound processor using an analog method.
