BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal video recorder (PVR) control technology, and more particularly, to an editing management system of a PVR suitable for synthesizing external audio information with pre-stored video information, and comparing and viewing the synthesized information.

Recently, with the development of digital technologies such as digital image compression and digital modulation / demodulation, the standardization and commercialization of digital television broadcasting is rapidly progressing. Also, in the conventional terrestrial, satellite, and cable broadcasting, MPEG (Moving Picture Experts Group) Based on this trend, digitalization is on the rise.

In digital broadcasting, a plurality of broadcast programs encoded on the basis of MPEG are multiplexed and transmitted in the form of a transport stream, which is received by a digital broadcast receiver such as a set-top box (STB) installed on the receiving side. The multiple broadcast programs included in the transport stream are demultiplexed.

Therefore, only one broadcasting program desired by the user can be selected. Also, in a digital broadcasting receiver such as a set-top box, the selected broadcasting program is restored to the original audio and video signal using an MPEG decoder provided in the receiver, The output is sent to the same A / V output device.

In addition, a large-capacity hard disk (HDD) is additionally provided in a digital broadcast receiver such as a set-top box, and a program stored in the hard disk is stored on a hard disk after being transmitted to an A / V output device such as a television. Digital broadcasting systems have been developed and released with the addition of a digital broadcast recording / reproducing function, for example, a 'PVR' function, for reproducing and outputting a broadcast program recorded on a disk, and is widely spread.

As is well known, the PVR is a personal recording / playback apparatus, and has a large storage medium, that is, a hard disk, for storing recorded data, that is, broadcast program data, and reproduces and outputs data stored in such a storage medium. Has the function to

Here, the broadcast program data stored in the storage medium is encoded (compressed) and stored in the MPEG2 method in order to increase the utilization of the storage space, and when the stored data is reproduced, it is decoded (restored) in the MPEG2 method and output. Therefore, the PVR can record a large amount of broadcast program data on a storage medium.

On the other hand, such a PVR outputs stored (or recorded) broadcast program data like a conventional recording / playback apparatus such as a VCR or DVD, and provides an operation function such as stop, skip, search, etc. according to the viewer's intention. .

That is, through the PVR, while watching broadcast program data such as foreign currency or overseas news with subtitles, the necessary section can be repeatedly watched through functions such as section repetition, and this language can be used as a language learning function. .

However, such a language learning function using the PVR has a disadvantage in that it does not deviate from the unilateral listening level because it is made only through repetitive learning of the output broadcast program. That is, there is a limit that the viewer can only be very passive because they learn while watching only a predetermined broadcast program.

Therefore, there is a need for a PVR control method that enables viewers to actively participate in learning while watching stored foreign currency or overseas broadcast programs.

SUMMARY OF THE INVENTION The present invention has been proposed in response to the above-described needs, and provides a PVR editing management system capable of synthesizing viewer development information with respect to a foreign currency program containing video information being reproduced, for example, in a separate storage space. There is a purpose.

The remote controller 100 outputs the voice information of the user according to the present embodiment. A microphone and a key button for synthesizing such voice information as dubbing information.

The key signal and the user voice information generated through the remote controller 10 are provided to the PVR 200 via the Bluetooth 102. As is well known, Bluetooth 102 refers to a standard that enables real-time communication in two directions by wirelessly connecting a computer, a mobile terminal, and a home appliance, which are located at a short distance, and means a product meeting the standard. In the example, the Bluetooth 102 is adopted to enable transmission of voice information and key signals.

The PVR 200 includes a receiver 20, an audio encoder 22, a mux 24, first and second storage units 26a and 26b, a de-mux 28, and a controller. (30).

As shown, the receiver 20 receives key signals and voice information from the remote controller 100 received through the Bluetooth 102, the audio encoder 22 is a user of the signals received from the receiver 20 The voice information is encoded and provided to the mux 24, respectively. In this case, the voice information provided from the audio encoder 22 to the mux 24 may be configured in the form of an element stream (ES).

The mux 24 adds, ie, inserts and outputs audio information from the audio encoder 22 to video information currently being reproduced in response to a dubbing control signal from the controller 30, that is, an audio editing management command. .

In addition, the first storage unit 26a and the second storage unit 26b are, for example, hard disk storage media, and information stored in the first storage unit 26a is read according to an operation process of the MUX 24, The dubbed information is stored in the second storage unit 26b. That is, the pre-recorded video object is stored in the first storage unit 26a, and the dubbing information added to the audio information while watching the pre-recorded video object as described below is stored in the second storage unit 26b, respectively. do.

In more detail, image information of the first storage unit 26a, for example, transport stream (TS) information, is provided to the mux 24 according to a control signal from the control unit 30, and the mux 24 provides such a mux 24. The user voice information ES is added to the video information of the first storage unit 26a to generate the dubbing information TS ', and the generated dubbing information TS' is stored in the second storage unit 26b. .

The demux 28 converts the image information stored in the above-described first storage unit 26a or the voice dubbed image information stored in the second storage unit 26b into a displayable signal and outputs it to the outside. .

Finally, the controller 30 is responsible for the overall operation of the PVR 200 as described above, and as a key input signal or user voice information is received through the Bluetooth 102, the mux 24 and the first storage unit ( 26a), the second storage unit 26b, the demux 28, and the like are controlled to perform the external audio editing process of the PVR according to the present embodiment.

Hereinafter, with reference to the above-described configuration, a process of editing external audio information of the PVR according to another embodiment of the present invention will be described in detail with reference to the flowchart of FIG. 2.

First, in step S200, the controller 30 determines whether a predetermined image stored in the first storage unit 26a is selected through the remote controller 100, and when the predetermined image is selected, the controller 30 performs the step ( In step S202, the PVR is driven to reproduce the selected video object.

Thereafter, the controller 30 determines whether dubbing is requested from the remote controller 100, as in step S204, and if dubbing is requested, the controller 30 proceeds to step S206 and dubbing by the PVR 200. Controls the mode to be set. In such a dubbing mode, the subtitle information is output in advance for a predetermined time while reproducing and outputting the video information stored in the first storage unit 26a, for example, a foreign currency program containing subtitles. That is, in the present embodiment, the purpose is to add (dub) his / her own development information when watching a foreign currency program loaded with subtitles through a PVR, and then assist in language learning while watching the added video information. That is, the viewer can confirm the pronunciation of the native speaker by checking the subtitle information in advance.

In operation S208, the controller 30 determines whether user voice information is input from the remote controller 100.

When the user voice information is input, the controller 30 proceeds to step S210 and adds the user voice information ES to the image information TS of the first storage unit 26a that is currently being reproduced so that the second storage unit ( The mux 24 and the like are controlled to write to 26b).

Therefore, the user's voice is added to the video currently being watched and recorded in the second storage unit 26b.

Thereafter, in step S212, the controller 30 determines whether the dubbing end button is input from the remote controller 100, and when the dubbing end button is input, the controller 30 proceeds to step S214 and dubs the image so far. The information TS 'is registered as dubbing information.

3 is a flowchart illustrating a process of outputting edited information of a PVR according to another embodiment of the present invention, showing a process of selectively outputting the dubbed video object according to the user's preference in FIG.

First, in step S300, the controller 30 determines whether dubbing information is requested through the remote controller 100, and when dubbing information is requested, the controller 30 proceeds to step S302 and the second storage unit 26b. Time-up dubbing information stored in) is list-up. That is, the list of dubbing information stored so far is displayed to the viewer through an external screen.

In step S304, it is determined whether any dubbing information is selected through the remote controller 100, and if any dubbing information is selected, the controller 30 proceeds to step S306 to determine whether speaker information is selected by the viewer. Judge. That is, in outputting the dubbing information, it is determined whether the pre-stored dubbed video object and the dubbed video object are separately allocated to left and right speakers (not shown) and output. This process is to add efficiency to language learning, such as pronunciation correction, while watching and comparing the original video with the voice added.

If the speaker information is not selected as a result of the determination in step S306, the controller 30 proceeds to step S308 to control the PVR 200 to output only the dubbing information stored in the second storage unit 26b.

However, as a result of the determination in step S306, when the speaker information is selected, the controller 30 proceeds to step S310 to output the dubbing information according to the selected speaker information, that is, the dubbed video object stored in the second storage unit 26b. And the PVR 200 to separately output the original video images stored in the first storage unit 26a. For example, the original speaker may be output through the left speaker, and the dubbed image may be output through the right speaker.

In addition, the volume of the left and right speakers may be differently set according to a user's need, so that the concentration of the original image or the dubbed image may be different. Such technical information may be implemented by those skilled in the art. As it grows easily known, detailed description thereof will be omitted.

As mentioned above, although this invention was concretely demonstrated based on the Example, this invention is not limited to this Example, Of course, various changes are possible within the range which does not deviate from the summary.

According to the present invention, after repeating the listening learning by repeating the section, the contents of the remote control may be dubbed and then the two speech signals may be alternately listened or listened to by both speakers, thereby improving speaking ability, and watching the speaker's mouth. This doubles the learning efficiency. In the case of entertainment, new contents of digital contents can be created by recording famous scenes of movies or dramas and dubbed dialogues by viewers.
