The electronic device 100 may communicate with the server 200 through a network such as the Internet network to receive information on the audience rating.

The server 200 can determine the broadcasting contents of the users based on the audience information received from the various electronic apparatuses and calculate the audience rating. For example, as shown in Fig. 2, the server 200 can collect audience information from a plurality of electronic devices 100-1 to 100-n. Here, the plurality of electronic devices 100-1 to 100-n may be devices such as a TV, a set-top box, an electronic blackboard, an electronic table, a large format display (LFD), a smart phone, a tablet, Lt; / RTI > The audience information provided by the plurality of electronic devices 100-1 to 100-n to the server 200 includes information enabling identification of the content viewed by the plurality of electronic devices 100-1 to 100-n do.

The electronic device 100 of FIG. 1 may be any one of a plurality of electronic devices 100-1 to 100-n that provide viewing information to the server 200 shown in FIG. That is, the electronic device 100 may be implemented as an apparatus that provides audience information to the server 200 and receives information on audience ratings from the server 200. Alternatively, the electronic device 100 of Fig. 1 may be omitted from a plurality of electronic devices 100-1 to 100-n that provide viewing information to the server 200 shown in Fig. In this case, the electronic device 100 may be implemented as an apparatus that receives information on the audience rating calculated based on the audience information provided by the other electronic devices to the server 200 from the server 200. [

The server 200 can calculate the audience rating in various ways. For example, the audience rating can be calculated by a content recognition method using techniques such as image analysis or automatic content recognition (ACR). According to one embodiment, a plurality of electronic devices 100-1 to 100-n are provided in a plurality of electronic devices 100-1 to 100-n to acquire feature information from contents viewed by a user, Information to the server 200 and the server 200 can calculate the audience rating by identifying what contents are viewed on each of the plurality of electronic devices 100-1 to 100-n based on the feature information.

According to an embodiment, a plurality of electronic devices 100-1 to 100-n may acquire text included in an output content image as feature information. For example, text such as a channel number, a channel name, a program name, a channel call sign, and a content title included in the content image may be obtained. Optical character recognition (OCR) techniques may be used for text acquisition.

According to another embodiment, a plurality of electronic devices 100-1 to 100-n may acquire an image included in an output content image as feature information.

The server 200 searches the database for the feature information matching with the feature information received from the plurality of electronic devices 100-1 to 100-n, and based on the content identification information corresponding to the retrieved feature information, It is possible to recognize the contents viewed on the display devices 100-1 to 100-n and to calculate the audience rating based on the recognition result.

In the example described above, the plurality of electronic devices 100-1 to 100-n transmits the feature information to the server 200 and the server 200 recognizes the content based on the description. However, The database of the server 200 described above is provided in the servers 100-1 to 100-n, and it is also possible to recognize contents by itself. In this case, the plurality of electronic devices 100-1 to 100-n transmit information about the self-recognized content to the server 200, and the server 200 can calculate the audience rating based on the information.

The server 200 can transmit information on the audience rating of a particular broadcaster channel to the electronic device 100 in real time. For example, the server 200 may send information about the current rating of the AAA broadcaster channel to the electronic device 100 at 1 minute intervals. Alternatively, the server 200 may transmit information on the audience rating of the specific period to the electronic device 100. [ For example, the server 200 may transmit information on the rating of the AAA broadcaster channel from 10:50 to 11:15 on 2017-04-19 to the electronic device 100.

The electronic device 100 may modify the broadcast schedule information based on the audience rating information received from the server 200 to provide various services to the user.

3 is a block diagram for explaining a configuration of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3, the electronic device 100 includes a communication unit 110, a memory 120, and a processor 130. The configurations shown in FIG. 3 are illustrative for implementing the embodiments of the present disclosure, and appropriate hardware / software configurations of a level obvious to those skilled in the art may additionally be included in the electronic device 100.

The communication unit 110 is configured to perform communication with an external device according to various types of communication methods. The communication unit 110 can be connected to an external server via a network such as the Internet to transmit and receive various information. The communication unit 110 may be a radio communication unit such as an infrared communication (IrDA), a radio frequency identification (RFID), a near field communication (NFC), a wireless fidelity (WiFi), an ultra wideband (UWB), a wirelessDisplay WirelessHD, Wireless Home Digital Interface (WHDI), Miracast, Wireless Gigabit Alliance, Wi-Fi Direct, Bluetooth (Bluetooth Classic, Bluetooth Low Weighted, Edge Zigbee, Digital Living Network Alliance (DLNA), ANT +, Digital Enhanced Cordless Telecommunications (DECT), Wireless Local Area Network (WLAN), AirPlay, Z-wave, 4LoWPAN, LTE D2D, GPRS, , Global System for Mobile communications (GSM), Universal Mobile Telecommunication System (UMTS), Long-Term Evolution (LTE), and Wireless Broadband (WiBRO).

The communication unit 110 may be implemented as a transceiver for performing at least one of the communication schemes as described above.

The electronic device 100 can receive various kinds of information from an external server through the communication unit 110. [ For example, the electronic device 100 can receive information on the audience rating from the server 200 via the communication unit 110. [

The electronic device 100 can receive broadcast schedule information through the communication unit 110. [ The broadcast schedule information may be provided from an external server or a broadcasting company.

Memory 120 may store instructions or data related to at least one other component of electronic device 100. [ The memory 120 may be implemented as, for example, a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The memory 120 is accessed by the processor 130 and read / write / modify / delete / update of data by the processor 130 and the like can be performed.

The term memory in the present disclosure may be a separate memory from the processor 130 or a ROM (not shown) or a RAM (not shown) in the processor 130 and may be a storage medium in the electronic device 100, For example, a micro SD card, a USB memory, or a web server via a network.

The memory 120 may store broadcast schedule information. The broadcast schedule information may be called broadcast schedule information. The broadcast schedule information includes information on the broadcast time of the broadcast program set by the broadcaster. According to one embodiment, the processor 130 may receive broadcast schedule information from an external server and store the broadcast schedule information in the memory 120, and according to another embodiment, the processor 130 may broadcast program information in metadata, The broadcast schedule information may be generated and stored in the memory 120 based on information on time.

The processor 130 may control the overall operation and functionality of the electronic device 100. The processor 130 may be implemented as, for example, a CPU, an ASIC, a SoC, a MICOM, or the like.

The processor 130 may correct an error in the broadcast time of the broadcast schedule information. For example, according to the broadcast schedule information, although the program A is broadcasted from 11:00 to 12:00, the actual broadcast time may have an error from 11:02 to 12:05.

According to the present disclosure, the processor 130 may correct the error of the broadcast schedule information based on the information on the audience rating received from the server 200. [

For example, the processor 130 may modify the start time of the program included in the broadcast schedule information based on the information about the audience ratings collected in the predetermined time range from the start time of the program included in the broadcast schedule information.

According to one embodiment, the processor 130 detects a point in time when a change in the audience rating exceeds a preset threshold based on information on the audience ratings collected in a predetermined time range from the start time of the program included in the broadcast schedule information, The start time of the program can be modified to a time corresponding to the detected time. The predetermined time range may be set to 5 minutes to 10 minutes, but is not limited thereto.

For example, if the preset time range is 10 minutes and the broadcast time of the program A shown in the broadcast schedule information is 11:00 to 12:00 in 2017-04-19, the processor 130 sets the broadcast schedule information Monitoring changes in audience ratings from 10 minutes prior to the start time, i.e. 10:50, to 10 minutes after the start time indicated in the broadcast schedule information, i.e., 11:10. Specifically, the processor 130 receives information on the audience rating of the channel that broadcasts the program A from the server 200 through the communication unit 110 in real time from 10:50 on 2017-04-19. The processor 130 monitors information on the audience rating received from the server 200, and detects when a change in audience rating exceeds a preset threshold. When the change in the audience rating exceeding the preset threshold value is detected at 10:55 on April 17, 2017, the processor 130 sets the start time of the program A to 11:00 on 2017-04-19 To 2017-04-19 at 10:55 am.

When the change of the audience rating exceeds the preset threshold value, that is, the point of time when the audience rating suddenly rises, it can be regarded as the time point when the advertisement ends and the program A starts and many users watch. In this disclosure, the exact program start time can be known by using the change of the audience rating as described above.

According to the embodiment in which the start time is modified in real time as described above, the service associated with the start time of the program can be provided at a more accurate timing. The service associated with the start time of the program may be, for example, a service for notifying the start of the program, a service for recording the program, and the like. For example, when scheduled recording is set for the program A, the processor 130 monitors the audience rating from about 10 minutes before 11:00 in 2017-04-19, which is the start time of the program A shown in the broadcast schedule information, It is determined that the time corresponding to the time point is the actual start time of the program A, and recording can be performed from that time point.

According to another embodiment, the program start time is not corrected in real time by receiving information on the audience rating in real time as in the above-described case, but the program start time is corrected with the audience rating information obtained after the program is started It is also possible.

For example, it is assumed that the preset time range is 10 minutes and the broadcast time of the program A shown in the broadcast schedule information is 11:00 to 12:00 on 2017-04-19. After the completion of the program A, the processor 130 displays the broadcast schedule information on the broadcast schedule information starting from 10 minutes before the start time indicated in the broadcast schedule information, for example, 10:50, 10 minutes after the start time, i.e., 11:10, to the server 100 and receive the information. The processor 130 analyzes the audience rating from 10:50 to 11:10 to detect the point in time when the change of the audience rating exceeds a preset threshold value. When a change in the audience rating exceeding the preset threshold value is detected at 11:02, the processor 130 updates the start time of the program A from 2017-04-19 at 11:00 on the schedule schedule information to 2017-04-19 It is corrected to 11:02 on the day.

As described above, the program recording service may be provided according to the embodiment in which the start time is later modified. For example, when the scheduled recording for the program A is set, the processor 130 performs recording from a predetermined time, for example, 10 minutes before 11:00 in 2017-04-19, which is the start time of the program A shown in the broadcast schedule information To generate the recorded content, and to delete the recorded portion before the modified start time, that is, the recorded portion from 10:50 to 11:02.

The end time of the program can be modified in the same way as the method of modifying the start time of the program. For example, the processor 130 may modify the end time of the program included in the broadcast schedule information based on the information on the audience ratings collected in the predetermined time range from the end time of the program included in the broadcast schedule information.

For example, if the preset time range is 10 minutes and the broadcast time of the program A shown in the broadcast schedule information is 11:00 to 12:00 in 2017-04-19, the processor 130 sets the broadcast schedule information The change in the audience rating from 10 minutes before the end time, 11:50 minutes, until 10 minutes after the end time indicated in the broadcast schedule information, that is, 12:10 is monitored. Specifically, the processor 130 receives information on the audience rating of the channel that broadcasts the program A from the server 200 through the communication unit 110 in real time from 11:50 on 2017-04-19. The processor 130 monitors information on the audience rating received from the server 200, and detects when a change in audience rating exceeds a preset threshold. If the change in the audience rating exceeding the preset threshold value is detected at 12:04 on March 14, 2017, the processor 130 updates the end time of the program A by 12:00 (2017-04-19) To 2014-04-19 at 12:04 am.

The point in time when the change in the audience rating exceeds the preset threshold, that is, the point in time when the audience rating suddenly falls, can be regarded as the time point when the program A ends and the advertisement starts and the many users turn to another channel. In this disclosure, the exact program end time can be known by using the change of the audience rating as described above.

According to the embodiment of modifying the end time of the program in real time as described above, the service associated with the ending time of the program can be provided at a more accurate timing. The service associated with the end of the program may include, for example, a service for automatically turning off the power at the end of the program, a service for recording the program, and the like.

According to another embodiment, instead of receiving information on the audience rating in real time as in the above-described case and correcting the program end time in real time, it is possible to correct the end time of the program with the audience rating information acquired after the end of the program It is also possible to do.

For example, it is assumed that the preset time range is 10 minutes and the broadcast time of the program A shown in the broadcast schedule information is 11:00 to 12:00 on 2017-04-19. After the completion of the program A, the processor 130 displays the broadcast schedule information at about 13:00 on 2017-04-19, for example, from 10 minutes before the end time indicated in the broadcast schedule information, that is, 11:50 10 minutes after the start time, i.e., 12:10, to the server 100 and receive the information. The processor 130 analyzes the audience ratings from 11:50 to 12:10 to detect the point in time when the change in the audience rating exceeds a predetermined threshold value. When a change in the audience rating exceeding the preset threshold value is detected at 11:53, the processor 130 updates the end time of the program A from 2017-04-19 at 12:00 on the schedule schedule information to 2017-04-19 I am revising it to 11:53 of the day.

As described above, the program recording service may be provided according to an embodiment in which the end time is later modified. For example, when the scheduled recording for the program A is set, the processor 130 performs recording for the program A shown in the broadcast schedule information, and sets the preset time after 12:00, which is the end time of the program A shown in the broadcast schedule information For example, 10 minutes, and the recorded portion after the modified end time, that is, the recorded portion from 11:53 to 12:10, can be deleted.

Referring to FIG. 5, the processor 130 determines whether the program set as the reserved recording program is started (S510). For example, the processor 130 searches for a program registered as a scheduled recording program to be broadcasted in the nearest future using broadcasting schedule information, for example, EPG metadata.

If it is determined that the program set in the scheduled recording program is not started (S510, Yes), the processor 130 determines whether or not the time obtained by subtracting the current time from the start time on the broadcast schedule information of the program for which the recording reservation is set is less than a predetermined time range R (S520). The processor 120 starts recording (S530), and starts monitoring the audience rating based on the audience rating information provided from the server 200 in real time.

Then, the processor 130 determines whether the change from the audience rating before T seconds to the current audience rating exceeds a preset threshold value [theta] (S540). Here, T seconds can be set to a time suitable for observing the amount of change. For example, 5 seconds.

If it is determined that the change from the audience rating before T seconds to the current audience rating does not exceed the preset threshold value (S540, No), the time obtained by subtracting the start time on the broadcast schedule information of the program for which the recording reservation is set from the current time, It is determined whether the set time range R has been exceeded (S550). That is, it is determined whether the current time has passed the start time on the broadcast schedule information of the program for which the recording reservation is set. If it is judged that it is not over (S550, No), the recorded data is discarded and waiting for N seconds. Where N seconds may be set to, for example, 5 seconds. Then, the processor 130 performs a process of monitoring the change rate of the audience rating.

If it is determined that the change from the previous viewing rate to the current viewing rate exceeds the predetermined threshold value? (S540, Yes), that is, if the viewing rate exceeds the preset threshold value, the processor 130 determines that the recording reservation (S570) whether the time obtained by subtracting the current time from the end time on the broadcasting schedule information of the set program is less than a predetermined time range (R). If it is determined that the current time has exceeded the start time on the broadcast schedule information of the program for which the recording reservation is set (S550, Yes), the processor 130 sets the recording schedule It is determined whether the time is less than a preset time range R (S570).

If it is determined that the time obtained by subtracting the current time from the end time on the broadcast schedule information of the program for which the recording reservation is set is less than the predetermined time range R (S570, Yes), the change from the audience rate before the T- (?) (S570). If it is determined that the change from the audience rating before T seconds to the current audience rating does not exceed the preset threshold value (S570, No), the time obtained by subtracting the end time on the broadcast schedule information of the program for which the recording reservation is set from the current time, It is determined whether the set time range R has been exceeded (S590). That is, it is determined whether the current time has passed the end time on the broadcast schedule information of the program for which the recording reservation is set. If it is determined that it is not over (S590, No), the processor 130 monitors the change rate of the audience rating again.

If it is determined that the change from the audience rating before T seconds to the current audience rating exceeds the predetermined threshold value? (S580, Yes), that is, if the audience rating falls below a preset threshold value, the processor 130 ends the recording (S595).
