It is illustrated.

Referring to FIG. 3, a computer user first accesses an Internet service provider (ISP) server, downloads an application program for implementing a method according to an embodiment of the present invention, and stores the downloaded application program on the HDD 140. Since the connection with the ISP server and the application program downloading process are already known, a detailed description thereof will be omitted. For reference, the present invention is to issue a file selection and playback command using the RF remote controller 400, rather than giving a command to the computer system 100 using a keyboard and a mouse which are peripheral devices of the computer system 100. An embodiment of the present invention will be described. In this case, the command input through the RF remote controller 400 is transmitted to the computer system 100, and the signal reproduced by processing the command in the computer system 100 is transmitted to a sound output device or a TV receiver that is located at a short distance from each other. In short, the process

First, in the standby mode in which the A / V file is not played, the desktop displayed on the monitor 150 of the computer system 100 is displayed on the TV receiver 400 through the wireless signal transmitter 200 and the wireless signal receiver 300. By transmitting to, the same screen is displayed on the two display devices 150 and 400. In this state, if a PC user selects an image or music file of a specific directory in the directory list by using the RF transmitter 400, the PC control data is demodulated in the RF signal receiver 180 and then the computer is executed. As transmitted to the control unit 120 of the system 100, the control unit 120 starts to play the selected image file or music file. When the video file or the music file is reproduced in the computer system 100, the reproduced video signal and the audio signal (or only the audio signal) are transferred to the A / V source through the video and audio output terminals of the computer system 100. The wireless signal transmitter 200 is transmitted to the wireless signal transmitter 200, and the wireless signal transmitter 200 transmits a video signal and an audio signal received through the I / F 205 according to the frequency oscillated by the oscillator 210. It modulates into RF signal and transmits wirelessly through antenna.

Then, the wireless signal receiver 300 spaced apart from the computer system 100 demodulates the RF signal received through the RF signal receiver 310 to detect only an audio signal and a video signal (or only an audio signal), and this is an audio signal. By separately outputting and zooming a video signal, the TV receiver 400 such as an HD TV can watch or listen to an image file or a music file played by the computer system 100.

In a system having a signal transmission process as described above, a method for a user to select and play an entire file in detail,

First, a user inputs an execution command of an application program according to an embodiment of the present invention through the RF remote controller 400. The execution command is transmitted to the control unit 120 through the RF signal receiving unit 180 as described above, so that the control unit 120 receives the input in step 500 and executes the downloaded application program. Accordingly, in step 510, a directory search is performed by an application program. Directory search is performed to find a directory for installing a virtual entire playback file according to an embodiment of the present invention. When the directory search is completed, the application program according to an embodiment of the present invention generates a full play file name (all play. All) for each lowest directory searched in step 510 (step 530) and displays it as a directory list (step 540). The display form of such a directory list is shown in Figs. For reference, the full play file name (all play. All) may be programmed to be generated only in the lowest directory where the playable video file and the music file exist, and the full play file name (all play. All) is the corresponding directory. It is desirable to first select the default value in.

By the above-described steps, a directory list as shown in FIG. 4 or FIG. 5 is displayed on the TV receiver or the monitor 150, so that the user may select and play only a specific music file or an image file or play the entire file. You can also select all to play all the files in that directory. As such, the user plays full. If all is ordered to play, the application program sequentially reads and plays all music or video files existing in the lowest directory in step 560. If a playback command by one file selection is received instead of the entire playback file name selection, the corresponding processing command may be performed in step 580. The application program according to the embodiment of the present invention may repeat steps 550 to 560 or terminate the application program in accordance with a processing command in step 570 according to whether or not the input of the end command.

That is, according to the embodiment of the present invention, the viewer selects the entire playback file by using the RF remote control 400 from the directory list displayed on the TV receiver in the living room, so that all the music files or the image files included in the directory are received on the TV receiver. You will be able to watch or listen conveniently.

As described above, according to the present invention, all of the A / V files included in a specific directory can be selected and executed according to one user operation, thereby providing the user with the convenience of remote control or mouse operation.                     

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. For example, in the embodiment of the present invention, a computer system has been described as an example, but the video or music files stored in a recording medium such as a DVDP or a system in which a plurality of video or music files are stored, such as Internet TV, are not changed. It can also be easily implemented in a stand-alone system that can be played back. In addition, not only the entire playback but also two or more files may be selected and played, and the file selection and playback may be performed by the IR remote controller as well as the RF remote controller. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
