Description

Audio output device and method {AUDIO OUTTING APPARATUS AND METHOD}

The present invention relates to an audio output apparatus, and more particularly, to an audio output apparatus and method for receiving and playing an audio file stored in a server.

Conventional audio output apparatuses output audio transmitted from broadcast stations to broadcast waves or reproduce audio information recorded on an audio recording apparatus, that is, a tape or a compact disc.

The audio provided from the broadcasting station is not composed of only the audio desired by the user, and thus does not meet the needs of the user.

In the case of playing a tape or compact disc composed only of audio information desired by the user, the user must purchase a tape or compact disc on which the desired audio information is recorded, and the audio information recorded on the tape or compact disc has its limitations. .

As described above, in the related art, only the audio provided by the broadcasting station unilaterally can be output or only the audio recorded in the audio recording device can be reproduced.

Accordingly, an object of the present invention is to provide an audio output apparatus and method for automatically receiving and playing various audios according to a user's taste from a server.

1 is a block diagram of an audio output apparatus according to a preferred embodiment of the present invention;

2 to 5 are views showing the flow chart of FIG.

The present invention for achieving the above object is an audio output unit, a server having a variety of audio files and a communication module for connecting the audio output device, a memory for storing various programs and information and audio files, and various information A control panel for displaying or inputting various information, and receiving an audio file selected by the user through the control panel from a server having the various audio files, and storing the audio file in the memory, and storing the stored audio file in the memory output unit. It characterized in that it comprises a central processing unit for controlling to output through.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram of an audio output apparatus according to a preferred embodiment of the present invention. The central processing unit 100 generally controls the audio output apparatus, and the memory 102 is the central processing unit 100. ), Processing program, various reference information, and audio file provided from servo are stored. The interface 106 interfaces the communication module 108 and the central processing unit 100. The communication module 108 is directly connected to the server by wire or wirelessly to interface between the server and the audio output device, or is connected to the server via wired or wirelessly through the Internet to interface between the server and the audio output device. The operation panel 104 includes a display unit for displaying an image under the control of the central processing unit 100 and a keypad having keys for the user to input various selections and commands. The audio output unit 110 outputs audio according to the audio file stored in the memory 102 under the control of the central processing unit 100.

First, referring to FIG. 2, which shows a flow chart of a selection agent program that allows a user to select only his / her desired audio from among audio provided by a server, the central processing unit 100 provides a user with a control panel 104. If the input selection key is provided, the process proceeds to step 112 accordingly. In step 112, the central processing unit 100 displays the selection guide on the display device of the operation panel 104. Here, the optional guide indicates that the user can select a song of a specific singer, select a music genre such as ballad, jazz, or simply select audio randomly provided by the server. Choose what you want.

In step 114, the central processing unit 100, if the user selects one option, proceeds to step 116, otherwise waits until the user selects. In step 116, the CPU 100 stores the selection selected by the user in the memory 102.

The audio output apparatus provides an audio file retrieval and transmission agent program to the server for retrieving and transmitting an audio file from a server at power-on or when a user downloads audio information. Referring to FIG. 3, which shows a flowchart of an agent program transmission method, the central processing unit 100 proceeds to step 118 at power-on or when a user issues an audio information download command. In step 118, the central processing unit 100 provides an audio file search and transmission agent program to a server. The audio file retrieval and transmission agent program is started in a server to retrieve an audio file according to the option, and transmits the audio file to an audio output device. Here, when the user selects a song of a specific singer, the audio file retrieval and transmission agent program searches for an audio file that is identified as the song of the singer. The audio file of the genre selected by the user is searched by comparing the features of all audio files included in the server with the server. Here, the feature may be an audio rhythm. When the search for the audio file is terminated as described above, the audio file search and transfer agent program disappears after transmitting the searched audio file to the audio output device.

In operation 124, the CPU 100 receives an audio file provided by the audio file search and transmission agent program from a server and stores the audio file in the memory 102.

The server also has an upgraded audio file output program for outputting the audio file that will have the audio file in the new format. The audio output apparatus provides an audio file output program search and transfer mobile agent program to a server for downloading the audio file output program at power on. The audio file output program search and transfer mobile agent program is started on the server and searches whether there is an upgraded audio file output program on the server. At this time, the audio file output program search and transfer mobile agent program transmits information indicating that an upgraded audio file output program exists to the audio output device if the upgraded audio file output program exists in the server, and then the upgraded audio file is transmitted. Send a file output program to the audio output device.

In step 124, the central processing unit 100 searches whether the audio file output program search and transmission mobile agent program of the server transmits information indicating that an upgraded audio file output program exists. At this time, when the information is transmitted, the CPU 100 proceeds to step 126, and otherwise terminates as it is. In step 126, the central processing unit 100 downloads the upgraded audio file output program from the server.

In the state where the audio file is stored as described above, the central processing unit 100 starts the audio file output program according to the user's audio output command and reads the audio file stored in the memory 102 to output the audio output unit ( 5, which shows a flow chart of the audio file output program at step 110, the central processing unit 100 reads the audio file from the memory 102 (130), and at step 130 The audio file read in step) is output through the audio output unit 110. When the output of one audio file is finished, the central processing unit 100 repeats the above steps (128) to (130) to continue the output of the next audio file.

As described above, the present invention has an advantage of allowing a user to listen to audio of a desired taste without purchasing an audio recording apparatus such as a tape or a compact disc. In addition, there is an advantage that can listen to a wide variety of audio even in a state that can not be provided with a large number of audio recording devices, such as in a vehicle.
