Description

  The present invention relates to a broadcast receiver, an audience rating measurement system, an audience rating measurement method, and an audience rating measurement program.

  Conventionally, various methods have been used to measure the audience rating of television broadcast programs. For example, there is a method of attaching an audience rating measuring device such as a people meter or an online meter to a television receiver.

  Such an audience rating measuring device is operated by a viewer of a television receiver in each household to be surveyed. As a result, the viewing record of the program in the surveyed household is automatically transmitted to a predetermined server through the Internet. Then, the audience rating is tabulated from the viewing record stored in the server. An example of an audience rating measuring device provided in a television receiver is described in Patent Document 1.

In a conventional broadcasting system using analog broadcasting, a television receiver cannot specify a broadcasting station selected by a viewer based on received radio waves. Therefore, the audience rating is measured using the audience rating measuring apparatus as described above.

  A broadcast receiver, an audience rating measurement system, an audience rating measurement method, and an audience rating measurement program according to an embodiment of the present invention will be described with reference to the drawings.

  Hereinafter, an audience rating measurement system using terrestrial digital broadcasting will be described as an audience rating measurement system, and a mobile phone will be described as an example of a broadcast receiver.

  In the following description, one-segment broadcasting (hereinafter abbreviated as one-segment broadcasting) is terrestrial digital broadcasting that uses one segment out of 13 segments that constitute a 6 MHz frequency band assigned to each broadcasting station. Details will be described later.

(1) Overview of Audience Rating Measurement System Configuration and Operation FIG. 1 is a diagram showing a configuration of an audience rating measurement system according to an embodiment of the present invention. As shown in FIG. 1, the audience rating measurement system 100 according to the present embodiment includes a broadcasting station 10, a transmitting station 20, a plurality of mobile phones 30, a base station 40, a communication network 50, and a server 60. In FIG. 1, only one mobile phone 30 is shown.

  The broadcast station 10 generates a broadcast signal by encoding and modulating program content data, for example, and transmits the broadcast signal to the transmitting station 20. The transmitting station 20 transmits the broadcast signal transmitted from the broadcast station 10 as a radio wave for terrestrial digital broadcasting.

  The mobile phone 30 receives the radio wave of the broadcast signal transmitted from the transmitting station 20, and reproduces the program of the broadcast station selected by the user. Also, the mobile phone 30 generates viewing information indicating the currently selected broadcast station from the received broadcast signal, and transmits it to the server 60 through the base station 40 and the communication network 50 every minute. As the communication network 50, for example, the Internet is used.

  The server 60 is a database server, for example, and accumulates viewing information transmitted from the plurality of mobile phones 30 every minute. As a result, the server 60 calculates and stores the viewing rate of the one-segment broadcasting program every minute based on the stored viewing information.

  Specifically, for example, the server 60 calculates the total number of mobile telephones 30 viewing the program for each broadcasting station (the number of viewers for each broadcasting station) based on a plurality of received viewing information, for example. The total number of mobile phones 30 viewing the program at the broadcasting station (the number of all broadcasting station viewers) is calculated. Then, the server 60 calculates the audience rating by dividing the number of viewers for each broadcasting station by the number of all broadcasting station viewers for each broadcasting station.

  The server 60 transmits the viewing rate of the stored one-segment broadcasting program to the broadcasting station 10 through the communication network 50. As a result, the broadcasting station 10 can obtain an accurate audience rating of the one-segment broadcasting programs that are aggregated every minute. Note that the broadcast station 10 may access the server 60 through the communication network 50 to acquire the accumulated audience rating. In this way, a broadcast provider and a program provider such as a program sponsor can easily obtain the audience rating of a one-segment broadcast program.

(2) Details of Configuration and Operation of Mobile Phone Details of the configuration and operation of the mobile phone 30 according to the present embodiment will be described. FIG. 2 is a block diagram showing the configuration of the mobile phone 30 according to one embodiment of the present invention.

  As shown in FIG. 2, the mobile phone 30 according to the present embodiment includes a digital broadcast receiving antenna 301, a tuner 302, an OFDM (Orthogonal Frequency Division Multiplexing) demodulator 303, and a TS (transport stream). A decoder 304, an AV (audio / video) decoder 305, a display device 306, an audio output device 307, a CPU (central processing unit) 310, a storage unit 311, a communication unit 312, and a mobile phone antenna 320 are included.

  The radio wave of the broadcast signal transmitted from the transmitting station 20 in FIG. 1 is received by the digital broadcast receiving antenna 301.

  The tuner 302 selects one-segment broadcasting by selecting the frequency of the broadcast signal received by the digital broadcast receiving antenna 301. This channel selection is performed by the user operating an operation unit of the mobile phone 30 (not shown).

  Here, the broadcast signal of the terrestrial digital broadcasting is composed of TS according to the MPEG (Motion Picture Experts Groupe) -2 standard. The TS of the broadcast signal is multiplexed with TS packets each including video data, audio data, and character data, and TS packets including PSI (Program Specific Information) indicating program configuration information and the like are multiplexed. The

  One type of PSI is NIT (Network Information Table). This NIT is defined in the MPEG-2 standard to associate information about a transmission path with a broadcast program.

  Specifically, the NIT includes a channel number for each broadcasting station, a frequency predetermined for each broadcasting station, identification information unique to each broadcasting station (hereinafter referred to as a network ID (identifier)), and modulation in the transmission path. The method etc. are included.

  The OFDM demodulator 303 demodulates the broadcast signal of the one-segment broadcasting and outputs a TS. The TS decoder 304 decodes the TS based on the PID (packet identifier), thereby outputting video data, audio data, and character data, and separating the NIT.

  The AV decoder 305 decodes the video data, audio data, and character data output from the TS decoder 304, outputs the video signal and the character signal to the display device 306, and outputs the audio signal to the audio output device 307.

  The display device 306 is configured by a liquid crystal display, for example. The audio output device 307 is configured by a speaker, for example. As a result, video and characters are displayed on the display device 306, and sound is output from the sound output device 307. In this manner, the one-segment broadcasting program is reproduced by the mobile phone 30.

  The TS decoder 304 provides the separated NIT to the CPU 310 every minute. The CPU 310 extracts the above network ID from the NIT. Then, CPU 310 identifies the selected broadcast station based on the extracted network ID, and the viewing information indicating the identified broadcast station is transmitted from communication unit 312 and mobile phone antenna 320 via base station 40 and communication network 50. To the server 60 of FIG.

  In this way, viewing information from the mobile phone 30 is transmitted to the server 60 of FIG. 1 every minute. Note that the CPU 310 may store viewing information in the storage unit 311.

(3) Transmission of terrestrial digital broadcast broadcast signal Here, transmission of a terrestrial digital broadcast broadcast signal will be described. Broadcast signals of terrestrial digital broadcasting are modulated by the OFDM method. In the OFDM system, information is transmitted by being distributed over many carrier waves having different frequencies. Each carrier wave includes QPSK (Quadrature Phase Shift Keying), 16QAM (16-position Quadrature Amplitude Modulation), 64QAM (64-position Quadrature Amplitude Modulation), Alternatively, they are independently modulated by various methods such as DQPSK (Differential Phase Shift Keying).

  In the transmission of the video signal, each frequency band of 6 MHz width is divided into 13 segments. The 13 segments can be divided into segment groups (hereinafter referred to as hierarchies) having up to three different modulation schemes. For example, 13 segments are divided into a layer using a QPSK method that is resistant to transmission errors (hereinafter referred to as a strong layer) and a layer using another modulation method such as 64QAM. One-segment broadcasting uses one segment of a strong hierarchy.

(4) Audience Rating Measurement Program Among the above operations in the mobile phone 30, the operation of the CPU 310 is performed based on the audience rating measurement program. This audience rating measurement program will be described.

  FIG. 3 is a flowchart of an audience rating measurement program according to an embodiment of the present invention. The operation of the CPU 310 based on this audience rating measurement program is started when viewing of a one-segment broadcasting program is started.

  As shown in FIG. 3, in the audience rating measurement program according to the present embodiment, CPU 310 determines whether or not NIT is given from TS decoder 304 in FIG. 2 (step S11).

  CPU 310 repeats the same operation when NIT is not given. On the other hand, when the NIT is given, the CPU 310 extracts the network ID from the given NIT (step S12). Then, CPU 310 specifies viewing station currently selected based on the extracted network ID and generates viewing information (step S13). Further, CPU 310 transmits the generated viewing information to server 60 in FIG. 1 (step S14).

  Thereafter, the CPU 310 determines whether or not the viewing of the one-segment broadcasting program has ended (step S15).

  The CPU 310 repeats the operations of steps S11 to S15 when the viewing does not end, and ends the audience rating measurement program when the viewing ends. In the above, the start and end of viewing of the one-segment broadcasting is performed by the user operating an operation unit (not shown) of the mobile phone 30.
