FIG. 4 is a diagram showing an operation sequence of the viewing information providing system according to the embodiment of the present invention. Here, the relationship between the mobile phone terminal 1 and the content server 3 as a viewing information providing apparatus is shown.
In FIG. 4, each viewer first operates the mobile phone terminal 1 owned while viewing a program broadcast on the TV receiver 2, and transmits channel information including the terminal ID to the content server 3 (S41). ). On the other hand, a request for deleting the viewing status TBL 37 managed by the content server 3 when an event such as termination of the built-in application or power-off occurs is transmitted (S42). The content server 3 accumulates these data and sequentially updates the viewing status for each channel (updating viewing status TBL).
In addition, the mobile phone terminal 1 transmits a viewing information acquisition request generated when the built-in application is activated to the content server 3 (S43), whereby the content server 3 counts the viewing status. (Aggregation TBL is updated), an aggregation result page is generated and returned to the requested mobile phone terminal 1 (S44).

  Furthermore, the content server 3 also performs management for guiding the viewer to a channel with the highest or lowest audience rating and with a high frequency of channel change based on the result of counting the viewing status. For this purpose, the CH information is transmitted to the requested viewer (S45). The mobile phone terminal 1 that has received the CH information activates a remote control function to switch channels.

The operation sequence described above will be described in detail with reference to the flowcharts shown in FIGS. 6 to 8 are flowcharts cited for explaining the operation of the content server 3, and FIGS. 9 and 10 are flowcharts cited for explaining the operation of the mobile phone terminal 1. In particular, FIG. The processing procedure of the program which is one embodiment of the present invention is also shown.
First, the viewer operates the mobile phone terminal 1 owned by the viewer to activate a built-in application (S91 in FIG. 9). At this time, the viewing information acquisition request transmission unit 11 of the mobile phone terminal 1 transmits a viewing information acquisition request (REQ) to the content server 3 (S92). Thus, a CHTML (Compact Hyper Text Markup Language) page in which viewing information is expressed from the content server 3 is received and displayed. For example, the content server 3 generates viewing information according to the following procedure.

In generating the viewing information, the content server 3 first receives the channel information including the terminal ID from the mobile phone terminal 1 by the terminal information receiving unit 31 (FIG. 6, S61). The channel information including the terminal ID is transmitted by the channel information transmitting unit 12 of the cellular phone terminal 1 by performing channel designation operation on the cellular phone terminal 1 owned by the viewer (S96 in FIG. 9). At this time, a channel designation signal is also output to the TV receiver 2 (S95). Thereby, the channel of the TV receiver 2 at the viewer's house is set to the designated channel.
In the content server 3 that has received the channel information including the terminal ID, the viewing status TBL update unit 32 refers to the viewing status TBL 37 to check whether the corresponding terminal ID is already registered (S62 in FIG. 6). For example, the terminal ID is newly registered in the viewing status TBL 37 and an area for storing the viewing status data is secured (S63).

On the other hand, if already registered, the channel is set (S64), that is, in the corresponding terminal ID area, the changed channel information is written in the channel information before the change, and the received channel information is written in the channel information after the change, Write the date and time information at the time of registration. Next, reception of a deletion request is checked (S65). The deletion request is generated and transmitted by the deletion request transmission unit 15 of the mobile phone terminal 1 when the application is terminated by operating the mobile phone terminal 1 owned by the viewer or when the power is turned off (FIG. 10). , S100, S101), the content server 3 receiving this deletes the data in the area corresponding to the terminal ID from the viewing status TBL 37 in the viewing status TBL update unit 32 (S66).
Further, the content server 3 performs time monitoring by the timer monitoring unit 35. Specifically, it is a check for totaling viewing information and creating a page for the viewing information, and monitoring whether a predetermined time (for example, 1 minute, 5 minutes, etc.) has passed (S67). If it is confirmed that the predetermined time has passed, the process proceeds to the next process (S68). If the set time is shortened here, the real-time property of the viewing information is improved, but the burden on the content server 3 is increased.

Next, when there is no event such as channel switching in a long range (for example, 24 hours), it can be considered that the application has not been terminated, or that the viewer has not been viewed due to forgetting to turn off the power. For this reason, when it is detected that a predetermined time has elapsed, the viewing status data corresponding to the corresponding terminal ID is deleted as expired data (S68).
Subsequently, the total TBL creation unit 33 of the content server 3 totals the viewing information for each channel based on the viewing status for each channel stored in the viewing status TBL 37 (S69), and the page information creation / transmission unit 36 A CHTML page for display on the mobile phone terminal 1 is created based on the tabulated viewing information (S70). And it transmits to the cellular phone terminal 1 which requested the viewing information acquisition request (S71, S72).

FIG. 11 shows an example of viewing information displayed on the mobile phone terminal 1. As shown in FIG. 11, the viewing information is entitled, for example, a real-time channel audience rating, and the audience rating for each channel is represented by a bar graph and numbers together with the current number of users.
In addition, in order to improve operability, the mobile phone terminal 1 monitors the passage of a certain time after the application is started, particularly without the viewer operating the mobile phone terminal 1 to send a viewing information acquisition request. Thus, a mechanism is also prepared for issuing a viewing information acquisition request when a time-over is detected (S97 in FIG. 10). As a result, a viewing information acquisition request is automatically transmitted to the content server 3 (S98), the CTMML page is received from the content server 3 by the page information receiving unit 13 and displayed on the display monitor via the display control unit 14. (S99).
Then, a deletion request is transmitted after the viewer ends the application (S100, S101), and the content server 3 deletes the viewing status data of the corresponding terminal ID.

On the other hand, when the CH information is requested in the process of S70 of FIG. 7, the content server 3 selects a channel based on the total result of the viewing information and transmits the channel information to the mobile phone terminal 1 (S74). ). Details are shown in FIG.
That is, when switching to the channel with the highest audience rating based on the aggregation result (A), the CH information creation / transmission unit 39 extracts the channel with the highest proportion of the aggregation TBL 38 and carries the channel information corresponding to the channel. It transmits to the telephone terminal 1 (S82). When switching to the channel with the lowest audience rating (C), the CH information creation / transmission unit 39 extracts the channel with the lowest ratio of the total TBL 38 and transmits the channel information corresponding to the channel to the mobile phone terminal 1. (S89).

On the other hand, when switching to a channel whose frequency of change is high (B), first, the timer monitoring unit 35 is set for the time. Here, it is assumed that three stages of instantaneous, relatively short-term, and long-term range can be selected. Here, the total TBL creation unit 33 extracts terminals that have changed CH within the preset time from the viewing status TBL 37 (S83). Then, filtering is performed on the channel before the change (S84), and the channel after the change is repeatedly aggregated for all terminals and all channels (S85, S86), thereby expressing the change frequency for each channel as a ratio. It becomes possible. The data totaled here is stored in the total TBL 40. The CH information transmission unit 39 selects the channel having the highest value from the total TBL 40 and transmits it to the requested mobile phone terminal 1 (S88).
Note that the mobile phone terminal 1 that has received the CH information via the CH information receiving unit 16 (FIG. 10, S102) generates a CH signal (infrared) corresponding to the channel and outputs it to the TV receiver 2. Thus, the channel is switched (S103). Here, the reference (the magnitude of the audience rating or the frequency of change) when the content server 3 instructs the channel change is determined by the request of the content provider or the viewer.

  As described above, the present invention uses the mobile phone terminal 1 to perform zapping without using a general television receiver 2 and imposing a load on the content server 3. Even when a person is watching another program, channel guidance to a popular program or the like can be realized. For this reason, the viewer does not overlook popular programs. In addition, it is possible to provide an environment in which the viewer can select an interesting program, and thus the viewer can enjoy the broadcast program more.

  2, the terminal information receiving unit 31, the viewing status TBL updating unit 32, the total TBL creating unit 33, the viewing information acquisition request receiving unit 34, the timer monitoring unit 35, the page information creating / transmitting unit 36, and the CH information transmission. The program including the procedure executed by each of the units 39 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by a server having a computer system and executed. An information sharing apparatus can be realized. The computer system here includes an OS and hardware such as peripheral devices.
