The present invention relates to a digital broadcast receiver, and more particularly, to an apparatus and method for automatically localizing a grading system corresponding to various regions in a digital broadcasting receiver based on RRT information.

A digital broadcasting receiver, commonly called a set top box, is a device configured with a TV receiver to receive various TV image data of multiple channels transmitted through a network or satellite, and transmitted through a network or satellite. Receive the digital broadcasting data compressed by the MPEG-2 method, decompress the compressed data, decode the encoded data, and convert the encoded data into a standard NTSC signal so that it can be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream type digital broadcast signal transmitted by a broadcasting station and broadcasts a channel selected from the broadcast signals received by transport demux. It is configured to extract the signal, decode the extracted broadcast signal in a moving picture experts group (MPEG) -2 scheme, and display the extracted broadcast signal.

At this time, the MPEG-2 method is an international standard for transmitting video and various data for next generation television broadcasting and satellite broadcasting. In MPEG-2, various signals for moving picture, sound, and other additional service information are programmed. : It is prescribed to packetize into bit streams such as PS) and transport stream (TS), and multimedia communication using MPEG-2 is carried by transmitting a lot of information in TS stream on the transmitting side. In addition, the receiving side extracts information carried by parsing from a TS stream including a plurality of information, and decodes the information.

On the other hand, in the digital broadcasting receiver as described above, it is mounted in a class restriction system suitable for the region or country depending on the region of use. However, when installing a rating system in a conventional digital broadcasting receiver, a separate software must be configured according to a target region in the market before the product release so that the rating system can be programmed in advance and be used only in that region. There was a problem.

Therefore, the digital broadcasting receiver is equipped with a grading system used in various regions in advance, and the local broadcasting system is automatically localized to the area of use by dynamically activating the grading system using the RRT information included in the TS. If implemented, it would be expected that a digital broadcast receiver with a single software could be used in multiple regions without software changes.

Accordingly, an object of the present invention is to provide an apparatus and method for automatically localizing a grading system corresponding to various regions in a digital broadcasting receiver based on RRT information.

The present invention for achieving the above object is an automatic localization apparatus of a rating restriction system in a digital broadcast receiver, an RRT parsing unit for parsing RRT information from a TS stream received from the tuner of the digital broadcast receiver, and a plurality of regions A grading system pool for storing a grading system of a grading system; a storage section for storing grading system localization information reconfigured according to the change of the RRT information and the RRT information; and RRT information and grading system localization information from the storage section. It is characterized in that it comprises a dynamic menu configuration for performing the automatic localization of the rating system by activating one individual rating system corresponding to the localization information in the grading system pool.

In addition, the present invention is a method for automatically localizing the rating system according to the region in the digital broadcasting receiver, (a) reading the RRT information and the rating system localization information, and (b) the RRT information and rating system Activating one individual rating system corresponding to localization information to localize the rating system; (c) parsing RRT information from a TS stream received from a tuner of the digital broadcast receiver; and (d) And reconfiguring the rating system localization information when the RRT information is changed.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 is a schematic block diagram of a digital broadcast receiver mounted in a plurality of rating systems according to a region to which an embodiment of the present invention is applied.

Referring to FIG. 1, first, the key input unit 118 generates a key data signal according to a user's key operation and applies the generated key data signal to the control unit (micom) 116.

The tuner unit 100 receives and tunes a broadcast signal TS stream from a terrestrial wave or satellite received through an antenna. The channel decoder 102 decodes the TS stream broadcast signal tuned from the tuner 100 in a manner of VSB, QPSK, QAM, etc. according to a transmission scheme, and applies the decoded TS to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102, divides the video stream into video, audio, and additional information streams, and applies the decoded video stream to the MPEG-2 decoder 106. Then, the MPEG decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110 to display the digital broadcast receiver display unit. (112) to be displayed on the screen.

The video processor 108 receives the video signal decoded and output from the MPEG-2 decoder 106 and converts the video signal into a displayable image signal on a screen of the display unit 112 connected to a digital broadcast receiver such as a CRT, PDP, LCD, etc. The audio processor 110 receives the audio signal decoded and output from the MPEG-2 decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114.

The controller 116 controls the overall operation of each part of the digital broadcast receiver, and generates and applies a control signal for performing a corresponding function according to the key data signal from the key input unit 118 to the corresponding function unit.

The RRT parser 120 parses RRT information from the TS stream received from the tuner 100 of the digital broadcast receiver. The grading system pool 122 stores a grading system of multiple regions to which to respond. The storage unit 124 is a nonvolatile storage device such as a flash memory and stores RRT information and graded system localization information.

The dynamic menu configuration unit 126 reads the RRT information and the grading system localization information from the storage unit 124 under the control of the control unit 116, and corresponds to one individual grading limit corresponding to the localization information in the grading system pool. Activate the system to perform automatic localization of the grading system.

Accordingly, in the digital broadcasting receiver according to the embodiment of the present invention, in automatically localizing a rating system based on the RRT, a digital broadcasting receiver set includes a rating limiting system used in various regions in advance, By using the included RRT information, the system dynamically activates the corresponding class restriction system and automatically localizes the digital broadcasting receiver set according to the region of use, so that the digital broadcasting receiver set having a single software can be used in various regions without changing the software. do.

Next, a description will be given of a control process for automatically localizing a rating system according to a region based on the RRT in the digital broadcasting receiver of the present invention having the above-described configuration.

FIG. 2 is a flowchart illustrating an operation control flow for performing a local grade system automatic localization based on RRT in a digital broadcasting receiver according to an embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when the power of the digital broadcast receiver set is turned on by the user, the controller 116 of the digital broadcast receiver enters the standby mode in step S200, and reads the RRT and the rating system localization information in step S202.

Thereafter, the controller 116 checks whether there is a rating system that matches the rating system localization information in the rating system pool 122 in the storage unit 124 (S204). The above graded system pool may be stored in a nonvolatile storage such as flash memory, or may be implemented to be stored independently in a separate memory for a graded system localization operation.

At this time, if there is a rating system in the region where the digital broadcasting receiver set currently exists in the rating system pool 122, the control unit 116 proceeds from the step (S204) to the step (S206) in the rating system pool. Localize the grading system by activating one corresponding grading system.

Subsequently, the control unit 116 analyzes the RRT information included in the broadcast signal TS stream received from the tuner unit 100 through the RRT parser 120 in step S208, and the digital broadcast receiver set is located in step S210. Check if local information changes.

For example, when a digital broadcasting receiver set is moved to a place that is applied to a different rating system, the RRT information may be changed, i.e., in case of moving between countries in neighboring countries in Europe, the RRT information may be changed. As the information changes, it is possible to recognize that the rating system applied to the digital broadcast receiver set must be different.

As a result of the analysis of the RRT information as described above, when the RRT information is changed in accordance with the movement of the digital broadcast receiver, the control unit 116 proceeds from the step S210 to the step S212 and ranks according to the region information where the digital broadcast receiver set is located. One system information is updated, and in step S214, the grade limit system localization information is reconstructed.

Then, the control unit 116 returns to step S206 again and repeats steps S206 to S210, while corresponding to the reconstructed grading system localization information, one individual grading limit corresponding to the grading system localization information. The system is activated to localize the grading system and to continuously check for changes in the RRT information.

As described above, in the present invention, in a digital broadcasting receiver for automatically localizing a rating system based on RRT, a digital broadcasting receiver set includes a class limiting system used in various regions in advance, and is included in a TS stream of a broadcast signal. By using the RRT information, the system dynamically activates the corresponding class restriction system and automatically localizes the digital broadcasting receiver set according to the region of use. Therefore, the digital broadcasting receiver set having a single software can be used in various regions without changing the software.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, in the present invention, when the digital broadcasting receiver automatically localizes the rating system based on the RRT, the digital broadcasting receiver set includes a rating restriction system used in various regions in advance, By using the included RRT information, the system dynamically activates the corresponding class restriction system and automatically localizes the digital broadcasting receiver set according to the region of use.
