2 is a flowchart illustrating an example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the communication unit 110 receives a broadcast signal including broadcast data and broadcast-related first EPG information from a broadcast network, and receives the broadcast-related second EPG information through an Internet network (S100). The first EPG may be an EPG provided by a broadcasting station, and the second EPG may be an EPG processed based on an EPG provided by the broadcasting station.

For example, the first EPG information may include only relatively simple and low-volume information such as a program title, program start and end times, and a brief description of the program. However, the second EPG information may additionally include various pieces of information produced by an EPG providing service company based on the first EPG information. For example, the second EPG information includes an identifier representing the program, a thumbnail image of the program, a detailed description of the program, related persons such as the director or actor of the program, genre information of the program, and a brief video of the program. However, the scope of the present invention is not limited thereto.

When the first and second EPGs are received, the controller 180 processes the first EPG to generate first broadcast-related information, and processes the second EPG to generate second broadcast-related information (S110). . Then, the first and second broadcasting related information is converted into a database in different data structures and stored in the data storage unit 160 (S120). Here, it is preferable that the first and second broadcast-related information are stored in a part of the nonvolatile storage means of the data storage unit 160.

While the first and second broadcast-related information are stored in the data storage unit 160, a request for broadcast-related information is received from an application running in the broadcast receiving device 100 (S130). Then, the controller 180 selectively searches a database corresponding to at least one of the first and second broadcast-related information according to a predetermined priority (S140), and based on the search result, the requested broadcast-related information Information is acquired (S150).

Here, as for the priority between the first and second broadcast-related information, the first broadcast information may be high, the second broadcast-related information may be high, and the first and second broadcast-related information may be the same. If the priority of the first broadcast-related information is high, the controller 180 searches only the database corresponding to the first broadcast-related information (that is, the first broadcast-related information is stored) to obtain the requested broadcast-related information. I can. Conversely, if the priority of the second broadcast-related information is high, the controller 180 may obtain the requested broadcast-related information by searching only a database corresponding to the second broadcast-related information. And, when the priority of the first and second broadcast-related information is the same, the controller 180 searches all databases corresponding to the first and second broadcast-related information to obtain the requested broadcast-related information. You may.

Meanwhile, the priority between the first and second broadcast-related information may be predetermined according to requested broadcast information, or may be predetermined according to an application requesting broadcast-related information. Also, the priority between the first and second broadcast-related information may be predetermined according to a country in which the broadcast reception device 100 is driven.

As another example, the priority between the first and second broadcast-related information may be predetermined depending on whether broadcast-related information requested by an application is included in the first and second broadcast-related information. For example, although it cannot be generated based on the first EPG received through the broadcast signal, the second broadcast for the program-related thumbnail image, which is broadcast-related information that can be generated based on the second EPG received through the Internet network. The priority of the relevant information can always be high. That is, when the application requests specific broadcast-related information that is not included in the first broadcast information and only included in the second broadcast-related information, the controller 180 searches only the database in which the second broadcast-related information is stored. Requested broadcasting related information can be obtained.

When the requested broadcast-related information is obtained, the controller 180 transmits the obtained broadcast-related information to the running application (S160). Then, the running application may perform a predetermined operation using the received broadcast related information.

For reference, in this specification, the first EPG and the over-the-air-based EPG are mixed and used for the EPG received through the broadcasting network, and the second EPG and the Internet-based EPG are mixed and used for the EPG received through the Internet network.

3 shows an example of conventional EGP-based broadcast information and broadcast-related information provided by the broadcast receiving device 100 according to the present invention.

Referring to FIG. 3A, it can be seen that a conventional broadcast reception device simply provides channel information and program schedule information for each channel. 3B, the broadcast receiving device 100 according to the present invention provides an image corresponding to a program, genre information of a program, person information related to a program, a plot of the program, and the like, along with basic information on the program. It can be seen that it can be provided additionally.

Although not shown in the drawing, the broadcast reception device 100 according to the present invention may basically provide program schedule information for each channel shown in FIG. 3A. In addition, when a specific program is selected from the program schedule information for each channel, additional information on the selected program may be provided as shown in FIG. 3B.

FIG. 4 is a diagram illustrating a process in which broadcast-related information is transmitted to an application based on EPGs received through heterogeneous networks in the TV 100, which is a type of the broadcast receiving device 100 according to the present invention. For reference, in FIG. 4, only components necessary for the process of generating and transmitting broadcast-related information among the transmission elements of the TV 100 are shown.

The broadcasting station 200 transmits a first EPG (a basic EPG provided by the broadcasting station) through a broadcasting network. Then, the TV 100 receives the first EPG and stores it in the first database 162 of the data storage unit 160. Although not shown in the drawing, the TV 100 may process and store the received first EPG into a predetermined data structure.

In addition, the first EPG is delivered to an EPG service company 210 that processes and services it, and the EPG service company 210 generates a second EPG to which various broadcast related information is added based on the first EPG. It is stored in the providing server 220. The second EPG may further include information such as a thumbnail image, a moving image, a storyline, a performer, and a genre about the broadcast program.

The second EPG stored in the EPG providing server 220 is stored in the second database 164 of the data storage unit 160 of the TV 100 through an Internet network. Although not shown in the drawing, the TV 100 may process and store the received second EPG into a predetermined data structure. That is, the TV 100 may separately store and use first EPG-based data received through a broadcasting network and second EPG-based data received through an Internet network.

As such, countries that provide EPG services through EPG service companies include Korea, the United States, the United Kingdom, France, Germany, and Spain, and such services will be provided in a number of countries in the future.

The controller 180 may selectively search for the first database 162 and the second database 164 in response to a request for broadcast-related information from an application, and obtain the requested broadcast-related information based thereon. For example, when a basic broadcast program schedule is requested, the controller 180 may obtain a basic broadcast program schedule by searching the first EPG-based first database 162 having higher reliability. However, when a video related to a broadcast program having a large data capacity is requested, the controller 180 may obtain a video related to a broadcast program by searching the second EPG-based second database 164 including more various information.

That is, the broadcast receiving device 100 may set at least one of the first database 162 and the second database 164 as a search target for the requested broadcast-related information according to the type of broadcast-related information requested from the running application. have.

FIG. 5 is a diagram conceptually illustrating a process of providing broadcast related information in the broadcast receiving device 100 according to an embodiment of the present invention.

The tuner 112 receives a broadcast signal including SI/PSIP-based broadcast information through a broadcast network. The tuner 112 is a part of the broadcast reception module of the communication unit 110. The rest of the configuration of the broadcast receiving module has been omitted for convenience of description. SI (Service Informaiton) is a protocol for transmitting broadcast information aggregated according to a certain classification, and PSIP (Program & System Information Protocol) is for transmitting information on broadcast programs based on the ATSC (Advanced Television System Committee) standard. It's a protocol.

The SI/PSIP interworking unit 240 extracts EPG from the broadcast signal received through the tuner 112 and outputs the extracted EPG to the broadcast-related information providing unit 260. EPG information extracted from a broadcast signal is referred to as'air wave-based EPG' in FIG. 5. The SI/PSIP interworking unit 240 may also be a part of a broadcast receiving module.

The Internet module 114 receives a signal including broadcast-related data from an Internet network. At this time, the Internet module 114 serves as a Service Delivery Platform (SDP). Receive data. Here, the SDP linking unit 250 extracts the EPG from the received signal and outputs the extracted EPG to the broadcast-related information providing unit 260. The EPG information extracted in this way was named'Internet-based EPG' in FIG. 5. The SDP interworking view 250 may form part of an Internet module.

When the over-the-air-based EPG and the Internet-based EPG are received, the broadcast-related information providing unit 260 processes the received EPGs to generate broadcast-related information, converts it into a database, and stores it. In this case, the broadcast-related information providing unit 260 may convert the two EPGs into a database to have different data structures and store them, or may merge and analyze the two EPGs into a database and store them as a single data structure.

After the generated broadcast-related information is stored, when a request for broadcast-related information is received from an application, the broadcast-related information providing unit 260 may search a database to obtain the requested broadcast-related information. For reference, the broadcast-related information providing unit 260 may be a conceptual block that comprehensively performs functions such as the control unit 180 and the data storage unit 160 described above.

Applications for requesting broadcast-related information from the broadcast-related information providing unit 260 may be very diverse, such as a broadcast guide, a viewing reservation, a channel banner, and a social center. Broadcast-related information requested by such an application may be extracted from an over-the-air-based EPG or may be extracted from an Internet-based EPG.

On the other hand, whether the quality of the over-the-air-based EPG or the Internet-based EPG is superior may vary from country to country. However, in general, the reliability of over-the-air EPG is higher than that of Internet-based EPG. This is because the over-the-air-based EPG is directly provided by a broadcasting station with high confidence, and the Internet-based EPG is created by an EPG service provider based on the over-the-air-based EPG.

However, in terms of the quantity of information provided, Internet-based EPGs are often superior to over-the-air EPGs. This is because the capacity allocated to the Internet-based EPG is larger than the capacity allocated to the airwave-based EPG. Therefore, the Internet-based EPG may contain large-capacity data such as program thumbnail images or program-related videos that are not provided by the airwave-based EPG.

6 is an example of information included in an over-the-air-based EPG and an Internet-based EPG by country.

The amount of information contained in the Internet-based EPG is large compared to the amount of information contained in the over-the-air-based EPG is common to all countries. As a representative example, it can be seen that Internet-based EPGs in each country include thumbnail images of programs with large data capacity. In addition, it can be seen that the Internet-based EPG may further include various information such as episodes, actors, and directors of programs that are not included in the airwave-based EPG.

The peculiar thing is that the Internet-based EPG contains a program ID, unlike the over-the-air EPG. The program ID can be used for removing duplicate program information and collecting ratings. And in the case of the US, it can be seen that the coverage of the over-the-air EPG is very low.

As described with reference to FIG. 6, information included in the over-the-air-based EPG and the Internet-based EPG may be different depending on the country. Therefore, the broadcast reception device 100 according to the present invention searches for a database generated based on an over-the-air EPG or a database generated based on an Internet-based EPG to obtain a broadcast-related signal requested by an application, Or you can decide whether to search for both. That is, the priority of the search for a database for acquiring broadcast-related information requested by an application by the broadcast receiving device 100 may vary depending on the country in which the broadcast receiving device 100 is driven.

On the other hand, the broadcast reception device 100 includes broadcast information that is included in broadcast-related information generated based on the Internet-based EPG, but is not included in the broadcast-related information generated based on the airwave-based EPG, which is predetermined. Regardless of the search priority, high priority may be given to broadcast-related information generated based on the Internet-based EPG.

For example, when an application requests a thumbnail image for a specific program included only in an Internet-based EPG, the broadcast receiving device 100 searches for only broadcast-related information generated based on the Internet-based EPG, and the requested thumbnail Images can be acquired.

7 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

A specific broadcast-related information request is received from an application (S200). Then, the control unit 180 of the broadcast reception device 100 determines whether the broadcast reception device 100 is connected to an Internet network (S210).

If the broadcast receiving device 100 is not connected to the Internet network, the controller 180 searches for broadcast-related information generated based on the over-the-air-based EPG (S220), and a specific broadcast is performed based on the search result. The related information is acquired (S230), and the acquired specific broadcast related information is delivered to the application (S240).

However, when the broadcast receiving device 100 is connected to an Internet network, the controller 180 searches for broadcast related information generated based on the Internet-based EPG (S250), and based on the search result, The information is acquired (S260), and the acquired specific broadcast related information is delivered to the application (S270).

That is, the broadcast reception device 100 according to the present invention may vary a search range in order to obtain broadcast related information based on a connection state of an Internet network.

FIG. 8 is a diagram for conceptually explaining that the method of driving the broadcast reception device of FIG. 7 is performed.

In FIG. 8, based on a request for specific broadcast-related information from an application, a result searched in the airwave-based EPG database DB1 is referred to as A, the result searched in the Internet-based EPG database DB2 is referred to as B, and finally the control unit The search result obtained by (180) is named C.

Referring to (b) of FIG. 8, for Korea, if the Internet network is not connected, the final search result by the controller 180 is a search result in the airwave-based EPG database, but if the Internet network is connected, the controller ( It can be seen that the final search result by 180) is a search result in the Internet-based EPG database.

On the other hand, in Europe, if the Internet network is not connected, the final search result by the controller 180 is a search result in the over-the-air-based EPG database. It can be seen that the search result in the EPG database and the search result in the Internet-based EPG database are merged.

If the search results in the two databases do not match, the controller 180 determines the search results in the airwave-based EPG database and the Internet-based EPG database based on a predetermined reliability ranking for the specific broadcast-related information. You can select one of the search results. The predetermined reliability priority may be different according to the specific broadcast-related information, or may be different according to the country in which the broadcast reception device 100 is driven.

That is, the broadcast reception device 100 according to the present invention may acquire specific broadcast-related information requested by an application by merging and analyzing a search result in the airwave-based EPG database and the search result in the Internet-based EPG database.

9 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

When the over-the-air-based EPG and the Internet-based EPG are received through the communication unit 110, the controller 180 determines a country in which the broadcast receiving device 100 is driven based on each of the received EPGs (S300). Then, the controller 180 determines whether the countries determined based on the two EPGs are the same (S310).

If the two countries determined in step S310 are the same, the controller 180 generates and stores broadcast-related information from the over-the-air-based EPG, and generates and stores broadcast-related information from the Internet-based EPG (S320). Broadcast-related information generated from the two EPGs may be stored in a database in different data structures, or may be merged with each other and stored in a database as a single data structure.

However, if the two countries determined in step S310 are different from each other, the controller 180 selects the country determined based on the over-the-air-based EPG as a country in which the broadcast reception device 100 is driven (S340). This is because there is a higher possibility that the country determined based on the information included in the received broadcast signal is actually the country in which the broadcast reception device 100 is driven.

Thereafter, the controller 180 changes the Internet address to receive the EPG through the Internet network to another predetermined network address corresponding to the country determined based on the over-the-air-based EPG (S340). Then, the control unit 180 receives a new Internet-based EPG from the changed Internet address (S350).

Then, the controller 180 generates and stores broadcast-related information from the over-the-air-based EPG, and generates and stores broadcast-related information from the Internet-based EPG received from the changed Internet address (S360).

As described above, the broadcast receiving device 100 according to the present invention can automatically determine or correct the country in which the country is actually driven, and receive an Internet-based EPG or a new Internet-based EPG based thereon. I can.

10 shows examples of a graphic user interface provided by a broadcast reception device according to the present invention according to the method of driving the broadcast reception device illustrated in FIG. 9.

Referring to (a) of FIG. 10, when the country to be driven based on the over-the-air EPG is changed, the broadcast receiving device 100 displays a corresponding graphic user interface 151A on the display unit 151. You can see that you can. Although not shown in the drawing, the broadcast reception device 100 may provide a graphic user interface for selecting a country in which the broadcast reception device 100 is driven.

Referring to (b) of FIG. 10, when the driving country is changed based on the over-the-air-based EPG, the broadcast receiving device 100 sets a new Internet address to receive the Internet-based EPG, and a graphic user interface 151B corresponding thereto. It can be seen that) can be displayed on the display unit 151. Meanwhile, although not shown in the drawing, the broadcast receiving device 100 may provide a graphic user interface for inputting a new Internet address for receiving an Internet-based EPG or for selecting a new Internet address.

11 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

A first EPG is received through a broadcast network, and a second EPG is received through an Internet network (S400). Then, the controller 180 generates broadcast-related information by merging the first and second EPGs and stores it in the data storage unit 160 (S410).

In this case, the controller 180 may consider a predetermined priority for the first and second EPGs. For example, for specific data not included in one of the first and second EPGs, but included in the other, the controller 180 may transmit the specific data regardless of the predetermined priority. It can be stored as broadcast-related information. As a more specific example, the controller 180 may store the thumbnail image included in the second EPG as broadcast-related information without considering the predetermined priority with respect to the thumbnail image for a program not normally included in the first EPG. have.

As another example, when data included in the first and second EPGs conflict with each other, the controller 180 broadcasts based on data included in the selected EPG among the first and second EPGs according to an added priority. You can also create relevant information. As a more specific example, the controller 180 may always add a higher priority to data included in the first EPG with respect to a broadcasting schedule for each channel. This is because the reliability of the first EPG is generally higher than that of the second EPG.

12 is a diagram for conceptually explaining that requested broadcast related information is provided according to the method of driving the broadcast receiving device illustrated in FIG. 11.

Referring to FIG. 12, it can be seen that the controller 180 can construct a database 290 by merging and analyzing the over-the-air-based EPG 270 and the Internet-based EPG 280. Since the merge analysis criterion for the over-the-air EPG 270 and the Internet-based EPG 280 has been examined with reference to FIG. 11, an example in which a schedule list for each channel is constructed will be described as a specific example thereof.

The controller 180 generates a channel list based on an over-the-air EPG. This is because the reliability of the over-the-air EPG is higher than that of the Internet-based EPG, and the possibility of the channel list being omitted from the over-the-air EPG is extremely low. The controller 180 may also generate a schedule list for each channel based on an over-the-air-based EPG. However, although not in the over-the-air EPG, the Internet-based EPG can be used for the schedule list in the Internet-based EPG. When generating program information included in a schedule for each channel, the controller 180 basically uses an over-the-air-based EPG, but may add information that is only present in the Internet-based EPG.

In addition, in FIG. 12, it can be seen that the default thumbnail image 300 may be used by the controller 180 separately from the over-the-air-based EPG and the Internet-based EPG. This may be a thumbnail image related to each program genre that is not included in the first EPG. When the Internet network is not connected, the controller 180 may provide a thumbnail image for each program genre stored in advance in association with broadcast-related information generated based on the first EPG.

In FIG. 12, a thumbnail image for each genre is exemplified as information for supplementing broadcast-related information based on the first EPG, but the scope of the present invention is not limited thereto. That is, the broadcast reception device 100 according to the present invention can be used to supplement broadcast related information based on the first EPG while separately managing information of a specific category not included in the first EPG.

13 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the communication unit 110 receives a broadcast signal including broadcast data and broadcast-related first EPG information from a broadcast network, and receives the broadcast-related second EPG information through an Internet network (S500). The first EPG may be an EPG provided by a broadcasting station, and the second EPG may be an EPG processed based on an EPG provided by the broadcasting station.

When the first and second EPGs are received, the controller 180 processes the first EPG (airwave-based EPG) to generate first broadcast-related information, converts it into a first database, and stores the information in the data storage unit 160. Then, the second EPG (Internet-based EPG) is processed to generate second broadcast-related information, converted into a second database, and stored in the data storage unit 160 (S520).

That is, the broadcast reception device 100 according to the present invention can manage a broadcast network and an Internet network by dualizing them. In addition, the first and second broadcast-related information is preferably stored in a part of the nonvolatile storage means of the data storage unit 160. Meanwhile, the broadcast related information may include various information such as channel information of broadcast content, genre information of broadcast content, thumbnail image related to broadcast content, start time and end time information of broadcast content. However, the scope of the present invention is not limited thereto.

Then, the controller 180 acquires genre information of the currently output broadcast content based on the first and second databases (S520). In this case, the controller 180 may selectively search the first and second databases to obtain genre information of the broadcast content. Priorities may be predetermined between the first and second databases. For example, only the first database may be searched, only the second database may be searched according to the predetermined priority, or both the first and second databases may be searched.

When the genre information of the broadcast content is acquired, the controller 180 may control the display unit 151 to implement a picture quality corresponding to the acquired genre information of the broadcast content (S530). The data storage unit 160 may store image quality information for each genre in first and second databases, and the controller 180 may implement image quality corresponding to the genre information of the broadcast content by referring to this. In this case, the image quality factor controlled by the controller 180 may include color temperature, contrast, saturation, hue, sharpness, and gamma control. However, the scope of the present invention is not limited thereto.

14 is a diagram illustrating a process in which broadcast-related information is transmitted to an application based on EPGs received through heterogeneous networks in the TV 100, which is a type of the broadcast receiving device 100 according to the present invention. For reference, in FIG. 4, only components necessary for the process of generating and transmitting broadcast-related information among the transmission elements of the TV 100 are shown.

The broadcasting station 200 transmits the first EPG through a broadcasting network. Then, the TV 100 receives the first EPG and stores it in the first database 162 of the data storage unit 160. Although not shown in the drawing, the TV 100 may process and store the received first EPG into a predetermined data structure.

In addition, the first EPG is delivered to an EPG service company 210 that processes and services it, and the EPG service company 210 generates a second EPG to which various broadcast related information is added based on the first EPG. It is stored in the providing server 220. The second EPG may further include information such as a thumbnail image, a moving image, a storyline, a performer, and a genre about the broadcast program. Meanwhile, in some cases, the EPG service company 210 may generate the second EPG by using data independent from the EPG received from the broadcaster.

The second EPG stored in the EPG providing server 220 is stored in the second database 164 of the data storage unit 160 of the TV 100 through an Internet network.

The controller 180 searches the first database 162 and the second database 164 to obtain genre information of broadcast content currently being output. Then, the controller 180 generates a quality control signal based on the acquired genre information. Then, the controller 180 may transmit the image quality control signal to the display unit 151, and the display unit 151 may implement image quality corresponding to the broadcast content based on the image quality control signal.

A specific example in which the controller 180 generates an image quality control signal will be described. First, the data storage unit 160 may store information on image quality optimally set for each genre of broadcast content or information on image quality set by a user for each genre of broadcast content.

The controller 180 acquires genre information of the currently output broadcasting content based on the first and second databases 162 and 164, and is stored in the data storage unit 160 in advance corresponding to the acquired genre information. Acquires information about the image quality.

Then, the controller 180 may generate an image quality control signal for controlling the image quality implemented by the display unit 151 based on the acquired image quality information. Here, the image quality factor controlled by the image quality control signal may include contrast, hue, saturation, color temperature, and sharpness. However, the scope of the present invention is not limited thereto.

15 shows an example in which the broadcast reception device 100 according to the present invention controls the picture quality according to the genre of broadcast content.

First, the controller 180 acquires genre information and time information of broadcast content based on the first and second databases, and then controls the image quality implemented by the display unit 151. If the broadcast content is a movie, the controller 180 may control image quality to improve clarity and enrich color, and at the same time control a color temperature to 6500K. If the broadcast content is news, the controller 180 may increase blue saturation, control a skin color to be emphasized, and control a color temperature to 13000K.

If the broadcast content is sports, the controller 180 may increase brightness and saturation and control a color temperature to 13000K at the same time. If the broadcast content is a drama, the controller 180 can control the color temperature to 9300K while emphasizing skin color and increasing gamma. If the broadcast content is a documentary, the controller 180 may increase saturation and control the color temperature to 11000K. If the broadcast content is a music video, the controller 180 may increase saturation, emphasize skin color, and control a color temperature to 13000K.

Meanwhile, data related to quality control for each broadcast content may be previously stored in the data storage unit 160. In addition, the quality control for each genre of broadcast content is not limited to the above-described examples.

16 shows examples of an image quality control method of the broadcast reception device 100 according to the present invention.

Referring to FIG. 16A, it can be seen that the control unit 180 of the broadcast reception device 100 can linearly and gradually increase a specific quality factor to reach a target value. Meanwhile, the controller 180 may linearly decrease to reach a target value, or may non-linearly increase or decrease a specific image quality factor.

Referring to (b) of FIG. 16, it can be seen that the controller 180 can gradually increase a specific image quality factor to correspond to a target value. Meanwhile, the controller 180 may gradually decrease a specific image quality factor to reach a target value.

This is to reduce the visual rejection that viewers feel by controlling the picture quality implemented by the display unit 151 according to the genre information of the broadcast content, but limiting the width of the change in picture quality over time.

17 and 18 show specific examples of controlling image quality in the broadcast receiving device 100 according to the present invention.

Referring to FIG. 17, it can be seen that when the broadcast content being output by the broadcast receiving device 100 is a documentary, the controller 180 emphasizes saturation to realize a more vivid and rich image. Referring to FIG. 18, when the broadcasting content being output is a drama, it can be seen that the controller 180 can implement a gentle image by emphasizing the skin color.

19 is an example showing a series of processes for controlling image quality in the broadcast receiving device 100 according to the present invention.

The series of processes may be performed in the order of channel information database formation, genre information acquisition, and quality control. First, in the channel information database process, broadcast-related information is generated based on an over-the-air-based EPG and stored in a first EPG database, and broadcast-related information is generated based on an Internet-based EPG and stored in a second EPG database. In FIG. 19, the first and second EPG databases are combined and shown as a channel information database. The channel information database stores broadcasting information for each time slot of the corresponding channel.

In this state, the channel is switched based on the user's operation. Then, the controller 180 compares the converted channel code with the channel code of the channel information database and performs a genre information acquisition process based thereon.

In the process of obtaining genre information, the controller 180 first performs a process of reviewing reliability of channel information. The detailed process is as follows. First, the controller 180 may determine whether the two pieces of information match or not by comparing information related to broadcast content being broadcast on a switched channel stored in the first and second EPG databases. More specifically, the controller 180 may compare the date, time, broadcast content title, etc. extracted from the two databases to determine whether the two pieces of information match.

If the information extracted from the two databases is different from each other, the controller 180 may give priority to over-the-air reception-based data stored in the first EPG database or Internet reception-based data stored in the second EPG database. However, if the information extracted from the two databases match, the controller 180 may assign the same priority to the two databases.

Next, a detailed method of obtaining the genre information of the broadcast content by the controller 180 will be described with reference to FIG. 20. 20 is a flowchart illustrating an example of a method of obtaining genre information of broadcast content in the broadcast receiving device 100 according to the present invention. Hereinafter, a method of obtaining the genre information will be described with reference to necessary drawings.

The controller 180 searches for a first database in which broadcast-related information based on an over-the-air EPG is stored and a second database in which broadcast-related information based on an Internet-based EPG is stored (S600). It is determined whether genre information is not searched (S610).

If genre information for the broadcast content is not searched for in both the first and second databases (YES), the controller 180 controls the picture quality implemented by the display unit 151 with the picture quality set as default. Do (S620). The quality set as a default may be set as a standard video mode of the broadcast reception device 100.

When genre information is searched for in the first and second databases (NO), the controller 180 determines whether genre information is searched only in any one of the first and second databases (S630). If genre information is searched only in one of the first and second databases (YES), the controller 180 obtains the genre information searched in the one database as genre information for the broadcast content. (S640).

However, if not (that is, when genre information is searched for in both the first and second databases, NO), the controller 180 determines whether the searched genre information matches (S650). If the searched genre information matches (YES), the controller 180 selects one of the searched genre information (S660). However, when the searched genre information does not match (NO), the controller 180 selects one searched genre information according to a predetermined priority (S670).

Refer to FIG. 19 again. In a state in which genre information of the broadcast content is obtained, the controller 180 determines whether a viewer has fixed a channel. This is the App timing Control process in Figure 19. More specifically, the controller 180 may transmit a signal for image quality control to the display unit 151 only when a predetermined time elapses after channel switching. This is because it is meaningless to control the picture quality to the picture quality corresponding to the broadcast content without fixing the channel.

When a signal for image quality control is received, the controller 180 may control the display unit 151 to extract a value corresponding to the received signal from a quality setting table according to a genre and implement a corresponding image quality. . The table shown in FIG. 19 is an example of a table including contrast, color, saturation, sharpness, and correlated color temperature (CCT) as quality control factors.

21 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the controller 180 acquires genre information of broadcast content based on a first database generated based on an over-the-air-based EPG and a second database generated based on an Internet-based EPG (S700), and the display unit 151 The picture quality implemented by is controlled to the picture quality corresponding to the acquired genre information (S710).

Then, the controller 180 acquires sub-genre information of the broadcast content (S720), and controls the picture quality implemented by the display unit 151 to a picture quality corresponding to the obtained sub-genre information (S720). ). The range of image quality control based on the obtained sub-genre information may be performed in a finer unit than the image quality control range in step S710.

Taking a case where the genre of broadcast content is a movie, a specific example of implementing the picture quality control method shown in FIG. 22 will be described. First, the controller 180 controls the display unit 151 to implement a picture quality corresponding to the entire movie genre, then recognizes which sub-genre the movie is included in, and implements the picture quality corresponding to the sub-genre. The display unit 151 is controlled so as to be performed. More specifically, the controller 180 may differently set the picture quality implemented by the display unit 151 based on whether the movie is an action genre, a horror genre, or a fantasy genre.

Meanwhile, the quality control range for each sub-genre of the movie may be performed within a predetermined range for the entire movie genre. For example, when the control range of a specific picture quality factor in a movie genre is set to 1 to 100, the range of picture quality control for each sub-genre of a movie is also preferably limited to 1 to 100. However, in some cases this may not be the case.

In FIG. 21, it has been exemplified that image quality control is performed according to a higher genre of broadcast content and then image quality control is performed according to a lower genre of the broadcast content, but the scope of the present invention is not limited thereto. For example, the controller 180 may immediately acquire sub-genre information of the broadcast content, and then directly control the picture quality implemented by the display unit 151 based thereon.

22 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the controller 180 acquires quality control information for each section of broadcast content based on a first database generated based on an over-the-air-based EPG and a second database generated based on an Internet-based EPG (S800). Here, the image quality control information for each section may be a value for setting the quality control factor for each section directly searched from the two databases. In addition, the image quality control information for each section may be obtained indirectly based on a screen characteristic for each section, a genre characteristic, or an acoustic characteristic for each section, which are searched from the two databases.

When the quality control information for each section of the broadcast content is obtained, the controller 180 may control the quality of the broadcast content for each section of the broadcast content (S810).

Hereinafter, specific examples of a picture quality control method according to the method of driving the broadcast reception device will be described with reference to FIGS. 23 and 24.

23 illustrates an example in which the quality of news content is controlled for each section according to the method of driving the broadcast reception device illustrated in FIG. 22.

In the news content, in the announcement screen section of the announcer, the controller 180 may control the display unit 151 to implement'image quality A'. Here, the quality A may be a quality basically set in the news genre. Then, in the section of the sports event scene, the controller 180 may control the display unit 151 to implement'image quality B'. Here, the image quality B may be an image quality set to correspond to a sports genre.

Then, in a section of the announcer's comment screen, the controller 180 may control the display unit 151 to implement'image quality A'again. Thereafter, the controller 180 may control the display unit 151 to implement'image quality C'in a section in which the movie scene is output. Here, the picture quality C may be basically a picture quality set to correspond to a movie genre.

As described above, the broadcast reception device 100 according to the present invention may control the display unit 151 to implement different picture quality for each section divided according to screen characteristics even within one genre.

FIG. 24 illustrates an example in which the quality of broadcast content is controlled for each section according to the method of driving the broadcast reception device illustrated in FIG. 22.

The controller 180 may control the display unit 151 to implement'image quality A'for section 1. In this case, specific values of image quality factors such as color or contrast corresponding to image quality A may be extracted from the first and second databases. This is the same for image quality B and image quality C, which will be discussed in the future.

In addition, the controller 180 may control the display unit 151 to implement “image quality B” in section 2 and “image quality C” in section 3.

As described above, the broadcast reception device 100 according to the present invention may control the picture quality for each section even within one genre, based on the picture quality control factor value predetermined for each section.

25 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the controller 180 analyzes the sound signal of the broadcast content (S900). Then, the controller 180 controls the image quality implemented by the display unit 151 based on the result of analyzing the acoustic signal (S910). For example, in a section in which a human voice is output as a result of the acoustic signal analysis, the controller 180 may control the image quality implemented by the display unit 151 so that the skin color of the person is emphasized.

26 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. Hereinafter, a method of driving the broadcast reception device will be described with reference to necessary drawings.

First, the controller 180 acquires genre information of the broadcasting content being output (S1000). Then, the controller 180 controls the sound output unit 152 to control sound output characteristics based on the acquired genre information (S1010). Meanwhile, since the process of obtaining genre information of broadcast content may be the same as or similar to the process reviewed in the above examples, a detailed description thereof will be omitted.

A specific example of sound output characteristic control according to the method of driving the broadcast reception device will be described. In the case of a news genre, the broadcast receiving device 100 may control the sound output characteristic of the sound output unit 152 to emphasize a human voice, and the sound output unit 152 to emphasize a background sound for a documentary genre. The sound output characteristics of the can be controlled.

FIG. 27 shows an example of a configuration diagram for explaining an implementation process of the method of driving the broadcast reception device shown in FIG. 26. Hereinafter, the method of driving the broadcast reception device shown in FIG. 26 is applied to the configuration of FIG. 27.

The controller 180 searches the first database 162 in which broadcast-related information generated based on the broadcast-based EPG is stored, and searches the second database 164 in which broadcast-related information generated based on the Internet-based EPG is stored. The genre information of the broadcasting content being output is acquired.

Then, the control unit 180 generates a sound output control signal for controlling the sound output unit 152 to implement a predetermined sound output characteristic corresponding to the acquired genre information, and the sound output unit 152 Output as Then, the sound output unit 152 may implement sound output characteristics corresponding to broadcast content in response to the sound output control signal.

The sound output characteristic control in the broadcast receiving device 100 according to the present invention described above may also be performed by further reflecting sub-genre information of the broadcast content, or may be performed for each section of the broadcast content being output.

28 is a flowchart illustrating another example of a method of driving a broadcast reception device according to the present invention. FIG. 29 shows an example of a configuration diagram for explaining an implementation process of the method of driving the broadcast reception device illustrated in FIG. 28.

A first EPG is received through a broadcast network, and a second EPG is received through an Internet network (S1100). Then, the controller 180 generates broadcast-related information by merging the first and second EPGs, converts the generated broadcast-related information into a database, and stores it in the data storage unit 160 (S1110). Since the first and second EPG merge processing has been described above, a detailed description thereof will be omitted.

Then, the controller 180 searches the database 166 to obtain genre information of the broadcasting content being output (S1120), and determines the image quality implemented by the display unit 151 based on the acquired genre information. Control (S1130). In this case, the controller 180 generates an image quality control signal for controlling at least one image quality factor and transmits the generated image quality control signal to the display unit 151 in order to implement image quality corresponding to the acquired genre information.

Meanwhile, the controller 180 may control output characteristics of sound output by the sound output unit 152 based on the acquired genre information. In this case, the controller 180 generates a sound output control signal for controlling at least one sound factor for implementing sound output characteristics corresponding to the acquired genre information, and transmits the generated sound output control signal to the sound output unit 152.

On the other hand, as shown in Fig. 28, over-the-air-based EPG and Internet-based EPG are integrated and processed into a database and managed, and genre information and sub-genre information of broadcast content obtained based on the data, sub-genre information, quality information for each section, and sound analysis As a result, the etc. can be applied to the embodiments described with reference to FIGS. 13 to 27. However, since this is a matter that is obvious to those of ordinary skill in the art to which the present invention belongs, a detailed description thereof will be omitted.
