It is effective to reduce the amount of data transmitted by providing information.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest.

FIG. 1 is a diagram illustrating a generally provided RRT table, and FIG. 2 is a flowchart for explaining a method of transmitting rating information of a video object according to an embodiment of the present invention.

First, the rating information transmission method according to the present invention may be applied to any one of an RF (Radio Frequency) signal received through an antenna or an external video signal stored in a recording medium such as a digital video disc (DVD) or a video tape. In the present invention, an external input signal input through an RF (Radio Frequency) signal and a DVD (Digital Video Disc) will be described as a main axis for better understanding of the description.

However, in the present invention, only the external input signal input from the RF (Radio Frequency) signal or the DVD (Digital Video Disc) will be described by way of example, but it is applicable to a video object provided from any medium on which a video object such as the video tape is recorded. Will be natural.

In general, a digital broadcast signal is transmitted in the form of a packetized transport stream by time division multiplexing a video signal, an audio signal, and additional data.

Here, the additional data is divided into various additional data defined by Program and System Information Protocol (PSIP) information.

Program and System Information Protocol (PSIP) information belonging to the additional data is a standard created to describe various information necessary for receiving a program and data transmitted from a digital TV, and all transport streams for a digital broadcasting receiver. It is a set of tables designed to operate within, and describes necessary information of a virtual channel transmitted in a specific TS to provide information necessary for reception of a receiver.

That is, the PSIP information is a packet ID for demultiplexing video and audio information from the modulation scheme, carrier frequency, and carrier stream of each channel required for normal reception of a broadcast program of each channel. (IDentification) information, program guide information (including program title, program start time, brief additional explanation, etc.), caption service presence, program rating, current time information, and the like.

As described above, PSIP (Program and System Information Protocol) information includes various tables, which include a system time table (STT) for transmitting time information, a master guide table (MGT) for managing a transmission table, and virtual channel information. It consists of a Virtual Channel Table (VCT) to provide, and a Rating Gegion Table (RRT) that defines grading criteria applicable to each region and country.

In particular, the RIP (Rating Region Table) information is included in the PSIP information table inserted and transmitted in the digital broadcasting signal according to the standard of the digital broadcasting system. The RRT information is used in a RS (Rating System) as shown in FIG. It consists of the area code, the name of the area, the number of RSs used in the area, and the name of each RS.

Accordingly, the user can grasp the rating information of the corresponding broadcast program using the information present in the RRT table, and accordingly, the user can perform the parental control function by blocking the output of the broadcast program exceeding a specific viewing rating. have.

However, the audience rating information is reference audience rating information determined based on the entire section of the corresponding video image, and specific sections outside the determined viewing rating exist in the detailed portion of the video product.

Accordingly, the method of providing a rating according to the present invention provides not only the reference rating of the viewer, which is determined by the average of the rating information of the video as a whole, but also the rating information of the corresponding video for each time based on the total running time of the video. .

PID 72 Title Stealth Time 16:12 Audience rating 12

That is, as shown in Table 1, it is subdivided by time based on the total running time of the broadcast program, and accordingly, the rating information according to the corresponding time is inserted into a predetermined position in which the additional information is stored.

For example, assuming that the total running time of the broadcast program is 10 minutes, the audience rating from 0 to 1 minute based on the hourly rating of the video is '5 years old audience' and the audience rating from 1 to 5 minutes. '15 -year-old audience ', the audience rating of 5 to 10 minutes is '18 -year-old or older' audience rating, respectively, inserts the rating information of the video in the predetermined position containing the additional information.

The PID is a packet ID.

At this time, the viewing rating is also provided with the reference rating information previously provided.

Accordingly, in order to effectively reduce the data amount of the provided additional information, only detailed rating information of a specific section exceeding the reference rating may be provided among sections divided by detailed time of the corresponding broadcast program.

That is, if the standard audience rating is '15 -year-old audience 'of a particular broadcast program, and if the rating is provided as described above, only the rating information of a specific section exceeding the standard viewing rating, that is, 5 to 10 minutes is provided. This reduces the amount of data, so that the receiving side can more effectively grasp the viewing grade of the video.

In addition, the video signal provided from the DVD (Digital Video Disc) includes additional information indicating the information of the video object.

The additional information includes title information, genre information, director information, character information, plot information, running time information, and rating information of the video.

The audience rating information is information indicating an age range in which the corresponding video can be viewed. For example, there are audience ratings such as' full audience ', '12 -year-old', '15 -year-old 'and '18 -year-old'. .

However, similar to the provided rating, the rating information is reference rating information determined based on the entire region of the corresponding video object, and the detail part of the video material has portions beyond the predetermined rating.

Accordingly, the method of providing a rating according to the present invention provides not only the reference rating of the viewer, which is determined by the average of the rating information of the video as a whole, but also the rating information of the corresponding video for each time based on the total running time of the video. .

Title Stealth Time 16:12 Track 37 Audience rating 12

That is, as shown in Table 2, the audience rating information according to the detailed time of each track is provided together with the corresponding image data on the basis of the track obtained by dividing the corresponding image object into a predetermined section.

In other words, the title information of the video, the running time information of the video, the track information for each section of the video divided into a predetermined area according to the running time, and the corresponding rating information for the detailed time of the video based on the track information. to provide.

Here, the same as the above is also provided with a reference rating, it is preferable to transmit the rating information of the video data only for a specific section based on the reference rating.

As shown in FIG. 2, in the method of providing viewing rating information of an image according to the present invention, first, detailed detailed ratings of the corresponding video item are analyzed at step S10.

Subsequently, the detailed rating information analyzed above is inserted at a predetermined position where the additional information is stored (S20). In this case, the detailed viewing rating information to be inserted also includes reference viewing rating information of the corresponding video.

Then, only the detailed rating information for a specific section of the video is inserted into the predetermined position by using the included reference rating information.

Subsequently, according to a user's request, the additional information into which the detailed audience rating information is inserted is transmitted on the corresponding video signal (S30).

The method for transmitting the rating information according to the present invention improves the user's satisfaction by providing detailed viewing rating information for each detailed time in addition to the reference rating information of the corresponding video, and provides detailed ratings for a specific section based on the reference rating information. By providing information, the amount of data transmitted can be reduced efficiently.
