The present invention relates to a method and apparatus for playing audio data together with A / V content provided from another source.

Many contents previously provided as analog signals are provided in digital form, and as the digital compression technology is advanced, the capacity of the provided contents is relatively small. In particular, MPEG layer 3 (hereinafter referred to as MP3), which is one of encoding algorithms of an audio signal, provides a high compression ratio while maintaining audio quality.

Therefore, many people these days are compressing music into MP3s and storing them in compact MP3 players or cell phones with built-in MP3 player functions and enjoying the music they want on the go.

In addition, people may store additional music using a memory stick such as a USB memory to carry more songs, connect the memory stick with the music to an MP3 player, or at home or at the office. You can also connect to your PC and listen to the music you want.

However, since music encoded in MP3 is excellent in sound quality, it can be used when storing songs for accompaniment. Therefore, using a memory stick, you can create a karaoke at any time you want. However, the MP3 player that supports the memory stick connection only outputs audio sound, so the singer can feel free because there is no visual stimulus.

Accordingly, the present invention has been made to solve the above problems, and provides a method and apparatus for reproducing and outputting audio data stored in a portable storage device such as a memory stick together with video content provided from another source as a background image. It is.

In order to achieve the above object, in the reproduction method according to the present invention, when reproducing data provided from a plurality of sources, the plurality of sources are decoded and outputted in audio data recorded in a first source of the plurality of sources. It is characterized in that the audio signal from the second source is always blocked and only the video signal is output together with the signal by the audio data.

In one embodiment according to the reproduction method of the present invention, a portable auxiliary memory storage device is used as the first source.

According to an embodiment of the present invention, after decoding the audio data and outputting the A / V content of the second source, the audio signal by the A / V content is blocked and only the video signal is output. The audio signal is output together with the audio signal.

According to another embodiment of the present invention, if there is a reproduction request of the audio data during the output of the content by the output request of the A / V content of the second source, the audio of the output A / V content is output. By blocking the signal, only the video signal by the A / V content is output together with the audio signal by the audio data.

Further, in one embodiment according to the present invention, if the audio data and the A / V content of the second source are designated to be reproduced together by a document file stored in the first source, in this embodiment, By executing the document file, the audio data and A / V content are simultaneously reproduced, and the output of the audio signal by the A / V content is blocked.

Hereinafter, a preferred embodiment of a method and apparatus for reproducing audio data together with other contents according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of an embodiment of an apparatus for reproducing an optical recording medium to which a method of reproducing audio data together with other contents according to the present invention is applied.

The optical recording medium reproducing apparatus of FIG. 1 includes a tuner 9 for tuning a television broadcast signal (A / V signal), a signal processor 10 for demodulating the tuned broadcast signal, and outputting a video and audio signal, and an external device. USB decoder 15 for USB connection, audio decoder 16 for decoding and outputting audio data encoded by formats such as MP3, wma, AC3, and signals of optical record carrier 1 such as DVD +/- R. An optical pickup 2 for reading out, an RF signal 20 for outputting a binarized reproduction signal from the read signal, an electrical signal for focusing error (FE) signal and tracking error (TE), and the binary reproduction A reproduction DSP unit 21 for restoring a signal to digital data and separately outputting management information and navigation data from the restored data; and audio and video from a muted PES packet sequence which is output data of the reproduction DSP unit 21; PES packet separation A / V decoder 22 for decoding and outputting A / V signals from each other, an OSD unit 33 for generating text and graphics signals, and a synthesizer 24 for synthesizing the video and text and graphics signals. And a servo control unit 31 for controlling the optical pickup 2 and its incident beam according to the focusing error signal and the tracking error signal and driving the spindle motor M for rotating the optical recording medium 1, navigation information. And a memory 32 in which data necessary for operation is stored, and a microcomputer 30 that processes user input and controls playback operations as a whole.

Hereinafter, the method of FIG. 2, which is an embodiment of a method of playing audio data along with other content according to the present invention, will be described in detail with the operation of the playback device of FIG. 1.

First, the user stores the audio data file that he / she wants to listen to in his / her memory stick by using a PC or the like and connects it to the USB interface 15 (S10). In addition to the audio data file, the memory stick may store a script file (or a document file) written in a mark-up language for linking the audio data with content of another source.

In addition, if necessary, the user inserts the disk 1 containing the content to be used as the background image (S10). When the disc 1 is inserted, by the control operation of the microcomputer 30, the navigation information in the navigation recording area of the disc 1 is read by the optical pickup 2, which causes the playback DSP unit 21 to read. Is restored to the data, and then stored in the memory 32.

In addition, when the user selects a playback menu through a normal user input means, for example, an input device such as a remote controller, the microcomputer 30 controls the OSD unit 33 to play as shown in FIG. 3. Configure and print the menu screen. This playback menu screen includes both the items in the memory stick and the contents (programs) recorded on the disc 1. In the information output on the playback menu screen as shown in Fig. 3, in the case of an item in the disk 1, from the navigation information loaded in the memory 32, in the case of an item in the connected memory stick, Known from the file system of memory.

In the playback menu screen output state, when a user selects one item to be played through a key input on the remote controller, the microcomputer 30 causes the selected item to be played back. Here, it is assumed that an item (one of numbers 4 to 6 in FIG. 3) in the connected memory stick is selected first for convenience of description of the present invention (S12).

The microcomputer 30 requests and reads the selected file from the file system of the memory stick and sequentially applies the data to the audio decoder 16. Then, the audio decoder 16 outputs the audio signal of the selected music by performing a decoding algorithm suitable for the compression format on the applied audio data (S14).

Meanwhile, the user requests again the playback menu screen of FIG. 3 through the input means and selects another program (S16). At this time, if a playback item is selected from the same source as previously selected (S18), it is ignored or the playback of the current item is stopped and the selected item is started to be played (S19). If the playback item is correctly selected from another source, that is, the disc 1 (S18), the microcomputer 30 controls the servo controller 24 with reference to the navigation information loaded in the memory 32 to control the optical pickup. A read operation is performed by moving (2) to the position where the selected program is recorded (S20).

The high frequency signal read by the optical pickup 2 is converted into a digital data stream by the RF unit 20 and the reproduction DSP unit 21, which is converted by the A / V decoder 23. Decoded and output as video and audio signals. At this time, when the audio data of the memory stick is currently being decoded and output (S22), the microcomputer 30 controls the semiconductor switch 11, such as a transistor in the audio signal line, to disconnect from the mounted disk 1. The audio signal is not output (S24), otherwise, both video and audio signals are output (S25). That is, while data is being read from the connected memory stick, the audio signal of the program selected on the disc 1 is muted so that only the video signal is output as the background image of the audio currently being reproduced.

On the other hand, after the user selects and plays back an audio data file, instead of manually selecting and simultaneously playing a program stored on the disc 1, a scripter file (document file) prepared in advance to be synchronized with each other is selected from the playback menu of FIG. By doing so, the music file of the memory stick and the background image of the disc may be simultaneously reproduced in one play request.

For example, when the script file 301 is selected in FIG. 3, the microcomputer 30 reads the file from the connected memory stick and starts the document with, for example, <script language = "JavaScript"> and Identify the language used in the document specified in the same form, then run the interpreter routine for that language, for example Java. By execution of the analysis routine, a file in the memory stick designated in the document, for example, the file of item 5 in FIG. 3 is read and decoded by the audio decoder 16, and in the document, for example, <Video src = "disc: //…"> One A / V content program on the disc 1 specified by the source tag is played in the form of "disc: //…"> so that the audio signal is muted and only the background signal Will be output together.

If the program specified in the selected script file is not present on the disc 1, the microcomputer 30 constructs a message guiding the fact and outputs it through the OSD unit 33 to display the screen. The message at this time may be displayed on a blank screen or a monochromatic screen, or may be superimposed on a broadcast program currently being broadcast on a channel that is currently set.

In addition, the user may make the background image of the broadcast signal instead of the video image on the disc 1 as the background image by not requesting playback of a program recorded on the disc 1 when playing music on the memory stick. Without a process, the device is designed so that one channel is always synchronized when not playing a disc). That is, when the currently set channel or the channel requested for change by the user is tuned and output from the tuner 9 under the control of the microcomputer 30, the signal processing unit 10 demodulates the tuned i / F signal. The microcomputer 30 outputs a video signal and an audio signal, and when the music file is currently read and decoded from the memory stick, the microcomputer 30 controls the semiconductor switch 11 to output the signal from the signal processor 10. Cut off the audio signal.

On the other hand, it is also possible to watch the background image of the music in the memory stick by changing the playback order of the above-described embodiment. 4 is a flowchart thereof.

The user first selects a program on the broadcast channel or the mounted disk 1 as the desired background image (S32). Then, the video signal and the audio signal of the selected broadcast channel or program are output together (S34).

At this time, the user connects the memory stick containing the music file to be sung to the USB interface 15 (may be connected earlier) and requests a playback menu screen. When the music file on the memory stick is selected on the playback menu screen of FIG. 3 (S36 and S38), the microcomputer 30 passes the data of the selected music file through the audio decoder 16 through the above-described process. Decoded output (S44). If an audio signal from a source other than the memory stick is currently being output (S42), simultaneously with or immediately before the decoding output, the microcomputer 30 controls the semiconductor switch 11 to control the current video signal. The audio signal of the broadcast signal or the disc reproduction signal being output together is cut off (S44).

In this manner, when the music file in the memory stick is played back, the audio signal outputted from another source is always muted, so that a karaoke system can be implemented in which a video signal provided from another source is a background image.

On the other hand, the present invention is not limited to the above-described typical preferred embodiments, but can be carried out in various ways without departing from the gist of the present invention, various modifications, alterations, substitutions or additions are common in the art Those who have knowledge will easily understand. If the implementation by such improvement, change, replacement or addition falls within the scope of the appended claims, the technical idea should also be regarded as belonging to the present invention.

According to the present invention described in detail above, when a user wants to sing a song using a lot of compressed music files stored in an auxiliary storage device such as a memory stick, a beautiful image provided through a larger amount of video content is used as a background image. You can do this to further enhance the feelings and interests of the person singing.
