Next, the operation of the content distribution system 1 described above will be described with reference to the drawings.
FIG. 18 is a sequence diagram showing content distribution processing in the content distribution system 1.
First, when a content reception application downloaded in advance by a user operation is activated on the mobile phone terminal 10 and an instruction for an authentication request is input to the mobile phone terminal 10 by the user, the mobile phone terminal 10 receives a UID. And an authentication request including the authentication flag is transmitted to the authentication server 31 (step Sa1).

  The authentication unit 31d of the authentication server 31 receives the authentication request from the mobile phone terminal 10, reads the authentication flag and the UID included in the authentication request, and refers to the authentication flag. When the authentication flag indicates “1: member authentication required”, the authentication unit 31d connects to the member information management server 35, and the UID received from the mobile phone terminal 10 is registered in the member registration information DB 35a-1. Authentication is performed by determining whether or not there is (step Sa2).

  When the UID is not registered in the member registration information DB 35 a-1, the authentication unit 31 d transmits an error response to the mobile phone terminal 10. On the other hand, when the UID is registered in the member registration information DB 35a-1, or when the authentication flag is “0: member authentication unnecessary”, the authentication unit 31d then changes the member registration information DB 35a-1 to the UID. The corresponding program reservation information is read from the distribution reservation DB 35a-2, and the UID and program reservation information is transmitted to the detection unit 31c.

  The detection unit 31c receives the UID and program reservation information from the authentication unit 31d, and reads the distribution start time of the program corresponding to the program ID included in the received program reservation information from the program corresponding connection destination DB 31a-1. . Next, the detection unit 31c acquires the current time from the clock 31f, and the program ID is a time close to several minutes before or after the time when the distribution start time has passed the time acquired from the clock 31f. Is detected. The detecting unit 31c reads the distribution server URL corresponding to the detected program ID from the program corresponding connection destination DB 31a-1. Then, the detection unit 31c transmits a connection destination notification including the read distribution server URL and the read program ID and having the content position number set to “0” to the mobile phone terminal 10 (step Sa3).

  On the other hand, in the recording device 40, when the moderator of the program corresponding to the program ID transmitted from the authentication server 31 to the mobile phone terminal 10 operates the recording device 40 to start recording, the recording device 40 sends the program ID to the distribution server 34. Is transmitted (step Sa4). The recording unit 34d of the distribution server 34 receives the first program division data (program division data (0)) from the recording device 40, and the program content in the program content DB 34a based on the program ID included in the program division data. Record program division data in the data list. At the time of recording, “0” indicating the beginning is added to the file name of the program division data.

  When image data or text data is received in addition to audio configuration data, a plurality of data items are recorded according to the number of data items, data storage offset, data length, data type, and configuration data format shown in FIG. Are recorded as one file.

  The mobile phone terminal 10 that has received the connection destination notification from the authentication server 31 reads the distribution server URL, program ID, and content position number from the connection destination notification, and uses the read distribution server URL, program ID, content position number, and UID. Send the distribution request to the network. The distribution request is routed in the network 50 based on the distribution server URL and reaches the distribution server 34 (step Sa5).

  The detection unit 34c of the distribution server 34 that has received the distribution request reads the program ID and the content position number from the distribution request, and reads the program division data (0) corresponding to the program ID and the content position number read from the program content DB 34a. . And the detection part 34c produces | generates the delivery response containing the read program division data (0). At this time, the error code of the distribution response is set to normal: 0, the program ID of the program division data (0) to be distributed is set to the program ID, and the program division data (1 to be transmitted next) is set to the content position number. “1”, which is the content position number of). In addition, data corresponding to the program division data (0) is set in the data count, data storage offset, data length, and data type. The detection unit 34c transmits the generated distribution response to the mobile phone terminal 10 that is the transmission source of the distribution request (step Sa6). The log generation unit 34e generates log data for transmission of the program division data (0) included in the distribution response and writes the log data in the log file.

  During this time, the next program division data (1) is transmitted from the recording device 40 to the distribution server 34, and the recording unit 34d of the distribution server 34 that has received the next program content data is included in the program division data (1). The received program division data (1) is recorded in the program content data list of the program content data 34a based on the existing program ID. At the time of recording, “1” is given to the file name of the program content data (step Sa7).

  The mobile phone terminal 10 that has received the distribution response including the data of the program division data (0) from the distribution server 34 reads out and reproduces the program division data (0) from the distribution response. Also, the content position number, that is, “1” is read from the distribution response, the data for the distribution request is generated, the content position number read from the distribution response is set as the content position number, and a certain time has elapsed after receiving the distribution response The distribution request generated after elapses is transmitted to the distribution server 34 (step Sa8).

  The detecting unit 34c of the distribution server 34 that has received the distribution request reads the program ID and the content position number from the distribution request, and reads the divided program data (1) corresponding to the program ID and the content position number read from the program content DB 34a. . And the detection part 34c produces | generates the delivery response containing the read division | segmentation program data (1). At this time, normal: 0 is set as the error code of the distribution response, the program ID of the divided program data (1) to be distributed is set as the program ID, and the content of the divided program data to be transmitted next is set as the content position number. The position number “2” is set. In addition, data corresponding to the divided program data (1) is set in the data count, data storage offset, data length, and data type. The detection unit 34c transmits the generated distribution response to the mobile phone terminal 10 that is the transmission source of the distribution request (step Sa9). The log generation unit 34e generates log data for transmission of the program division data (1) included in the distribution response and writes the log data in the log file.

  In the above distribution process, the recording device 40 edits the audio configuration data every 15 seconds, edits the configuration data other than the audio configuration data registered in the recording screen 41 during the 15 seconds, Two pieces of program division data are generated and transmitted to the distribution server 34. On the other hand, the mobile phone terminal 10 receives the distribution response, reproduces the configuration data included in the distribution response, and transmits the distribution request when the reproduction ends. That is, transmission / reception between the recording device 40 and the distribution server 34 and transmission / reception between the mobile phone terminal 10 and the distribution server 34 are performed independently, and the delay of the network 50, the distribution server 34, etc. If there is no processing delay due to a high load, the processing from step Sa7 to step Sa9 is repeated. However, when a delay occurs, program content data that has not been distributed to the mobile phone terminal 10 is stored in the distribution server 34.

  When the recording in the recording device 40 is completed, an end notification is transmitted from the recording device 40 to the distribution server 34 (step Sa10). The detection unit 34c of the distribution server 34 receives the end notification. Then, the distribution request transmitted from the mobile phone terminal 10 is received (step Sa11), and the content position number included in the distribution request is read out. The detection unit 34c detects whether or not the program division data corresponding to the read content position number exists in the program content data list of the program content DB 34a. Here, since the corresponding program division data does not exist, “1: end” is set in the error code of the distribution response, and is transmitted to the mobile phone terminal 10 (step Sa12).

  The mobile phone terminal 10 that has received the distribution response reads the error code, and since the error code is “1: end”, the transmission of the distribution request to the distribution server 34 is terminated, and the program content reserved next In order to obtain the URL of the distribution server that distributes the data, a connection destination request including the UID and having the error code set to “1: end” is transmitted to the authentication server 31 (step Sa13). Upon receiving the connection destination notification, the authentication server 31 performs connection destination determination processing described later.

  In the content distribution process described above, the cellular phone terminal 10 receives a distribution response including the program division data requested by the distribution request within a certain period of time after transmitting the distribution request, for example, within 30 seconds due to radio wave conditions or the like. If not, resend the distribution request.

  Communication between the mobile phone terminal 10 and the distribution server 34 and the CM distribution server 32 is performed based on http (Hyper Text Transfer Protocol), and a distribution request transmitted from the mobile phone terminal 10 is an HTTP request message. The distribution response transmitted from the distribution server 34 and the CM distribution server 32 is performed using an http response message. In the distribution request, the UID, program ID, and content position number are set as variables added after the distribution server URL, and the model name is set in the header part.

  Next, processing for determining a connection destination in the authentication server 31 will be described with reference to FIGS. FIG. 19 is a sequence diagram showing the processing of the content distribution system 1 when the program distributed from the distribution server 34A ends and there is a free time until the start time of the next program distributed from the distribution server 34B. .

  Here, the case where the distribution server 34A has already received the end notification from the recording device 40 will be described. First, the distribution server 34A receives a distribution request from the mobile phone terminal 10 (step Sb1). Receiving the distribution request, the detection unit 34Ac of the distribution server 34A reads the content position number included in the distribution request. Since the divided program data corresponding to the content position number does not exist in the program content data list of the program content DB 34Aa, the distribution response error code is set to “1: end” and transmitted to the mobile phone terminal 10 (step Sb2). ).

  The mobile phone terminal 10 that has received the distribution response reads the error code, and since the error code is “1: end”, the transmission of the distribution request to the distribution server 34A is completed, and the URL of the next server to be connected is set. In order to obtain it, a connection destination request in which “1: end” is set in the error code is transmitted to the authentication server 31 (step Sb3).

  The detection unit 31c of the authentication server 31 that has received the connection destination request performs a connection destination determination process described later (step Sb4). Then, by the connection destination determination process, the detection unit 31c detects that the next program reserved by the user of the mobile phone terminal 10 has not yet started, and within the time until the next program starts. A CM-ID of CM content data having a reproduction time and having the maximum reproduction time is detected from the CM corresponding connection destination DB 31a-2. At this time, CM content data having a reproduction time within the time until the program is started and the CM content data having the maximum reproduction time may be detected. However, more than half of the CM content data is distributed. You may make it detect CM content data on condition that it can do.

  Then, the CM distribution server URL corresponding to the detected CM-ID is read from the CM-compatible connection destination DB 31a-2, and the UID, the read CM distribution server URL, the CM-ID, and the content position number “0” are set. A prior notice is transmitted to the mobile phone terminal 10 (step Sb5). The mobile phone terminal 10 that has received the connection destination notification reads the CM distribution server URL, the CM-ID, and the content position number from the connection destination notification, and obtains the UID, the read CM distribution server URL, the CM-ID, and the content position number. The distribution request including this is transmitted to the CM distribution server 32 (step Sb6).

  Upon receiving the distribution request, the detection unit 32c of the CM distribution server 32 reads the CM-ID included in the distribution request, and obtains the first CM divided data (0) corresponding to the read CM-ID as the CM of the CM content DB 32a. Read from the content data list. Then, the detection unit 32c of the CM distribution server 32 sets the error code to 0, sets the CM-ID, the read divided CM data (0), and “1” that is the content position number of the divided CM data to be distributed next. The distribution response including this is transmitted to the mobile phone terminal 10 (step Sb7). Thereafter, the processing of step Sb6 and step Sb7 is repeated during the playback time of the CM content data.

  While the processes of steps Sb6 and Sb7 are repeated, the detection unit 33c of the management server 33 acquires the current time from the clock 33e at regular intervals. Then, the detection unit 33c has a program ID that has a distribution start time that has passed the time acquired from the clock 31f from the program guide DB 33a of the program guide DB 33a, or a time close to several minutes before and after the time. Whether the program ID is present or not is detected. Then, the priority corresponding to the detected program ID is read from the program table DB 33a, and a progress state notification including the program ID and the priority is transmitted to the CM distribution server 32. At this time, the progress state notification is also transmitted to all the distribution servers 34 (step Sb8).

  The CM distribution server 32 that has received the progress notification performs priority determination processing described later, and detects that the priority of CM content data distributed by itself is lower than the notified priority. When it is detected that the priority of CM content data distributed by itself is lower than the notified priority, the CM distribution server 32 subsequently receives a distribution request from the mobile phone terminal 10. (Step Sb10), a delivery response in which “2: halfway” is set in the error code to the mobile phone terminal 10 is transmitted to the mobile phone terminal 10 (Step Sb11).

  The mobile phone terminal 10 that has received the distribution response in which “2: halfway” is set in the error code is set when the UID, the program ID that has received the distribution from the distribution server 34A, and the last distribution request are transmitted. A connection destination request in which “2: halfway” is set as the content position number and the error code is transmitted to the authentication server 31 (step Sb12). The authentication server 31 that has received the connection destination request performs the connection destination determination process again (step Sb13). Here, also in the connection destination determination process, it is determined that the distribution start time has passed the current time, or there is a program that starts at a time close to several minutes before and after the current time, and the corresponding program A connection destination notification in which “0” is set as the program ID, the distribution server URL of the distribution server 34B that distributes the next program, and the content position number is transmitted to the mobile phone terminal 10 (step Sb14).

  The mobile phone terminal 10 that has received the connection destination notification from the authentication server 31 reads the distribution server URL, program ID, and content position number from the connection destination notification, and uses the read distribution server URL, program ID, content position number, and UID. Send the distribution request to the network. The distribution request is routed in the network 50 based on the distribution server URL and reaches the distribution server 34B (step Sb15).

  The detection unit 34Bc of the distribution server 34B that has received the distribution request reads the program ID and the content position number from the distribution request, and reads the program content data (0) corresponding to the program ID and the content position number read from the program content DB 34Ba. . Then, the detection unit 34Bc generates a distribution response including the read program content data (0), and transmits the generated distribution response to the mobile phone terminal 10 that has transmitted the distribution request (step Sb16).

Next, the connection destination determination process will be described with reference to FIG.
FIG. 20 is a flowchart showing a connection destination determination process performed by the authentication server 31 described above. The detection unit 31c of the authentication server 31 receives the connection destination request from the mobile phone terminal 10 (step Sc1 (corresponding to steps Sb3 and Sb12 in FIG. 19)). The detection unit 31c reads the error code, the program ID, and the content position number from the connection destination request. Then, it is determined whether the read error code is “1: end” or “2: halfway” (step Sc2). When the error code is “2: halfway”, the detection unit 31c reads the current time from the clock 31f, and the distribution start time has passed the current time, or a time in the vicinity of several minutes around the current time. The program ID of the program to be started is detected from the program corresponding connection destination DB 31a-1 (step Sc3).

  Next, the detection unit 31c reads the priority of the program ID included in the connection destination request and the priority of the detected program from the program corresponding connection destination DB 31a-1. Then, the priority of the program ID included in the connection destination request, that is, the priority corresponding to the program ID of the program that has finished receiving the program content data is compared with the priority corresponding to the detected program ID. Then, it is determined whether or not the priority corresponding to the detected program ID is higher than the priority corresponding to the program ID of the program that ended halfway (step Sc4). If the priority corresponding to the detected program ID is the same as or lower than the priority corresponding to the program ID of the program that ended halfway, the mobile phone terminal 10 continues to distribute the program content data that ended halfway. I will let you. At that time, the authentication server 31 reads the distribution server URL corresponding to the program ID of the program ended halfway from the program corresponding connection destination DB 31a-1, and connects the distribution server URL and the program ID of the program ended halfway. A connection destination notification including the content position number read from the previous request is transmitted to the mobile phone terminal 10 (step Sc5).

  On the other hand, when the priority corresponding to the detected program ID is higher than the priority corresponding to the program ID of the program that was terminated halfway, new program content data with a higher priority is received by the mobile phone terminal 10. At that time, the authentication server 31 reads the distribution server URL corresponding to the detected program ID from the program corresponding connection destination DB 31a-1, and sets “0” as the detected program ID, the read distribution server URL, and the content position number. The received connection destination notification is transmitted to the mobile phone terminal 10 (step Sc6).

  On the other hand, when the error code is “1: end” in step Sc2, the detection unit 31c reads the current time from the clock 31f, and the distribution start time has passed the current time, or the number before and after the current time as a reference. The program ID of the program started at the time near the minute is detected from the program corresponding connection destination DB 31a-1 (step Sc10). Then, the detecting unit 31c determines whether or not there is a corresponding program ID, that is, a distributable program (step Sc11). If there is no distributable program, the difference between the distribution start time of the program that is started first and the current time is calculated, and the reproduction time that is the longest among the CMs that have the reproduction time within the calculated difference time The CM-ID of the long CM and the CM distribution server URL are detected from the CM corresponding connection destination DB 31a-2. Then, a connection destination notification in which “0” is set as the detected CM-ID, CM distribution server URL, and content position number is transmitted to the mobile phone terminal 10 (step Sc12 (corresponding to step Sb5 in FIG. 19)).

  On the other hand, if there is a distributable program, it is next determined whether there are a plurality of distributable programs (step Sc13). If there is only one program that can be distributed, the program ID and distribution server URL of the program that can be distributed are read from the program corresponding connection destination DB 31a-1, and the read program ID, distribution server URL, and content position number are read out. A connection destination notification in which “0” is set is transmitted to the mobile phone terminal 10 (step Sc14 (corresponding to step Sb14 in FIG. 19)). On the other hand, when there are a plurality of deliverable programs, the program IDs of all the deliverable programs are detected from the program corresponding connection destination DB 31a-1, and the program ID corresponding to the program with the highest priority among them is set. The distribution server URL is read from the program corresponding connection destination DB 31a-1. Then, a connection destination notification in which “0” is set as the read program ID, distribution server URL, and content position number is transmitted to the mobile phone terminal 10 (step Sc15 (corresponding to step Sb14 in FIG. 19)).

Next, priority determination processing will be described with reference to FIG.
FIG. 21 is a flowchart showing the priority determination process performed by the CM distribution server 32 or the distribution server 34 described above. Hereinafter, since the processing performed by the CM distribution server 32 and the distribution server 34 is the same, the processing will be described using the processing unit of the distribution server 34.

  First, the detection unit 34c of the distribution server 34 receives the progress state notification from the management server 33 (step Se1 (corresponding to step Sb8 in FIG. 19)). At this time, when the distribution server 34 that has not distributed the program content data receives the progress notification, the received progress notification is discarded. The detection unit 34c of the distribution server 34 that is distributing the program content data reads the program ID included in the received progress state notification and determines whether or not it matches the program ID that is being distributed (step Se2). If they do not match, the detection unit 34c reads the priority corresponding to the program ID being distributed from the program content DB 34a. Then, the priority included in the progress notification is compared with the read priority, and it is determined whether or not the priority included in the progress notification exceeds the read priority (step Se3). .

  When the priority included in the progress notification exceeds the read priority, the next time a distribution request is received from the mobile phone terminal 10, a distribution response including “2: halfway” in the error code Is generated and transmitted to the mobile phone terminal 10.

  On the other hand, when the priority included in the progress notification does not exceed the read priority and the program ID being distributed matches the program ID included in the progress notification in step Se2. Next, when a distribution request is received from the mobile phone terminal 10 (corresponding to step Sb10 in FIG. 19), the program division data corresponding to the content position number included in the distribution request is read from the program content DB 34a and read. The distribution response including the program content data is generated and transmitted to the mobile phone terminal 10 (step Se5 (corresponding to step Sb11 in FIG. 19)).

FIG. 22 is a diagram for explaining the reproduction time control of program content data realized by the above configuration.
FIG. 22A is a diagram showing the program progress status to be performed based on the distribution time set in the program guide DB 33a and the program corresponding connection destination DB 31a-1. When communication delay does not occur due to congestion of the network 50 or occurrence of a state where communication is not possible in the mobile phone terminal 10, the playback status played back by the mobile phone terminal 10 is as shown in FIG. Program A, CM, and program B are reproduced at the same time as 22 (a).

  However, when a communication delay occurs and the reproduction of the program A is delayed, the CM is distributed by the progress notification notified from the management server 33 described above while the CM is being reproduced. Thus, the CM distribution server 32 ends the distribution of the CM content data, and the mobile phone terminal 10 can transmit the connection destination request to the authentication server 31 and receive the distribution of the program B from the beginning. In other words, as shown in FIG. 22 (c), the management server 33 can transmit the progress status notification based on the distribution time stored in the program guide DB 33a, so that the CM playback time can be arbitrarily shortened. The user of the mobile phone terminal 10 can receive the program B that the user wants to receive at a preset start time or a time in the vicinity thereof.

  Further, as shown in FIG. 22 (d), if the distribution start time of the program B has already passed or is close to the time when the distribution of the program A is completed, the authentication server 31 has a free time. It is also possible to determine that there is no mobile phone terminal 10 and connect it directly to the distribution server 34 that distributes the program B without connecting the mobile phone terminal 10 to the CM distribution server 32. In this case, the authentication server 31 detects an appropriate connection destination based on the distribution time stored in the program corresponding connection destination DB 31a-1 without notification of the progress state by the management server 33, and the mobile phone. The telephone terminal 10 is connected to the detected connection destination.

Next, viewing information generation processing will be described with reference to FIG.
FIG. 23 is a diagram showing a viewing information generation procedure in the content distribution system 1 described above.
In step Si1, the mobile phone terminal 10 transmits a distribution request for requesting program division data to the distribution server 34 (corresponding to FIG. 18, steps Sa5, Sa8,...), And the distribution server 34 requests the distribution request. A distribution response including the divided program data is returned to the mobile phone terminal 10 (corresponding to FIG. 18, steps Sa6, Sa9,...).
At this time, the log generation unit 34e of each distribution server 34 generates log data corresponding to each distribution request received from the mobile phone terminal 10, and writes the log data in the log file (step Si2). Specifically, when the processing until the detection unit 34c receives the distribution request and transmits the distribution response including the program division data requested by the distribution request is completed normally, the log generation unit 34e Log data is generated and written to the log file in the log file storage unit 34g. The log data includes the UID and model name included in the distribution request, the program ID and division number of the program division data distributed by the distribution response, the transmission time of the distribution response, the number of bytes sent out of the division data, and “normal”. And status information indicating is written. The time when the delivery response is transmitted is obtained from the clock 34f. The number of bytes to be sent is the size of the http response body. On the other hand, when an error occurs between the reception of the distribution request and the transmission of the distribution response in the detection unit 34c and the processing ends, the log generation unit 34e displays the UID, model name, program ID, and the like included in the distribution request. Log data including the division number, the processing end time acquired from the clock 34f, and status information indicating "abnormal" is written to the log file.

  The viewing information management server 37 collects log files from the distribution server 34 at a predetermined time of the day (step Si3). That is, the recording unit 37b of the viewing information management server 37 transmits a log request to the distribution server 34 at a predetermined time of the day. The detection unit 34c of the distribution server 34 reads the log file that is currently the log data write destination from the log file storage unit 34g and returns it to the viewing information management server 37. After transmitting the log file, the log generation unit 34e finishes writing to the log file and generates a new log file. Thereafter, the log generation unit 34e writes log data to a newly generated log file. For this, for example, log rotation is used. A specific example in the case of using log rotation will be described. The log file storage unit 34g stores log files “log_1”, “log_2”,..., “Log_7” every day for one week, and “log_1” is the newest log data currently being written. It is a log file, and “log — 7” is the oldest log file. After the latest log file “log_1” is transmitted to the viewing information management server 37, the log generation unit 34e changes the name of the file that has been “log_6” to “log_7” and the file that has been “log_5”. The name of each log file is changed to the name of one old log file so that the name of the file that was “log — 6”,..., “Log — 1” is changed to “log — 2”. Then, a new log file “log_1” is generated and log data is written.

  The predetermined time for collecting the log file is that the mobile phone terminal 10 divides the program even if a transmission delay occurs such as when the time corresponding to the length of the program elapses from the time when the program content data distribution ends. This time is assumed to be the end of data reproduction, and may differ depending on each distribution server 34. The distribution server 34 stops the distribution of the program content data from the time when the distribution of the program content data ends until a predetermined time when the log file is collected. This prevents log data for distribution of the same program content data from being divided and written into a plurality of log files.

The viewing information management server 37 writes the log file received from the distribution server 34 via the transmission / reception unit 37a to the log DB 37c (step Si4).
After collecting the log files from all the distribution servers 34, the aggregation processing unit 37d performs aggregation processing based on the log data in the log file stored in the log DB 37c, generates viewing information, and writes it in the viewing information DB 37e ( Step Si5). As viewing information, the total number of views for each program ID and each division number, the number of views by carrier, the number of views by model, the number of views by model series, the ratio of the number of views to the number of viewable terminals, the number of views for the program capacity There is information about the ratio. The number of viewable terminals is the number of mobile phone terminals 10 equipped with a content data reproduction application. Information on the ratio of the number of views to the number of viewable terminals includes the total number of views and the number of views by carrier. Information on the number, the number of viewers by model, and the ratio of the number of viewers by model series. The information on the ratio of the number of views with respect to the program capacity includes information on the total number of views with respect to the program capacity, the number of views by carrier, the number of views by model, the ratio of the number of views by model series, and the like.

  Specifically, the aggregation processing unit 37d reads log data for each identical program ID and identical division number from the log file. Then, out of the read log data, the data whose status is “abnormal” is excluded, and the log data with the same UID as the transmission destination is excluded except for the data with the latest time. The log data remaining in this way is set as viewing number calculation log data. By excluding log data whose status is “abnormal”, the program division data is not transmitted to the mobile phone terminal 10, that is, the number of views is counted by the log data where the program division data is not viewed. It is possible to effectively and accurately calculate the number of views. Further, when the same UID is the transmission destination, it is assumed that the mobile phone terminal 10 cannot receive the program division data due to radio waves or network conditions, and retransmits the distribution request for the same program division data. That is, only the program division data indicated by the last log data is viewed and the program division data indicated by the other log data is not viewed. Therefore, by excluding the log data of the same UID other than the latest for the transmission destination, it is possible to prevent the number of viewers from being counted twice by the log data of the program division data that has been retransmitted, It is possible to effectively calculate the accurate number of views.

The totalization processing unit 37d obtains the total number of viewings of the program division data for each program ID and each division number from the number of viewing count calculation log data for the same program ID and the same division number. Further, the carrier and model series corresponding to the model in each viewing number calculation log data are read from the carrier table in the viewing information DB 37e. Then, from the number of log data by carrier, model, and model series for the same program ID and the same division number, the number of viewings by carrier of the program division data for each program ID and each division number, the number of viewings by model Find the number of viewers by model series.
Subsequently, the totalization processing unit 37d divides the total viewing number for each program ID and each division number, the viewing number for each carrier, the viewing number for each model, and the viewing number for each model series by the number of viewable terminals. And the ratio of the number of views to the number of viewable terminals for each division number is calculated. As for the number of viewable terminals, for example, an application download server for downloading a playback application is installed on the network 50, and the number of downloads of the playback application to the mobile phone terminal 10 is counted in this application download server to manage viewing information. It can be acquired by notifying the server 37.
Further, the totalization processing unit 37d determines the total number of viewers for the same program ID and the same division number, the number of viewers by carrier, the number of viewers by model, the number of viewers by model series, and the number of programs identified by the program ID. And the ratio of the number of views to the program capacity for each program ID and each division number is calculated. The capacity of each program is obtained by reading from the program guide data held in the program guide DB 33a of the management server 33.

  The viewing status browsing terminal 60 accesses the viewing information management server 37 via the network 50 and transmits a viewing status browsing request. When receiving the viewing status browsing request from the viewing status browsing terminal 60, the detection unit 37f of the viewing information management server 37 reads the viewing information from the viewing information DB 37e. The detection unit 37f may read all viewing information, or may read viewing information that matches a condition specified by the viewing status browsing terminal 60 (for example, the program ID “A00001”). The display control unit 37g generates viewing information display screen data for displaying the viewing information read by the detection unit 37f on the screen as a graph (step Si6), and returns it to the viewing status browsing terminal 60 (step Si7). For the viewing information display screen data, html or the like is used. The viewing status browsing terminal 60 displays the viewing information display screen data received from the viewing status browsing terminal 60 on the browser provided therein.

  FIG. 24 is a diagram illustrating an example of a graph display of viewing information displayed on the viewing information display screen data. In the figure, for each of the division numbers “1” to “10” of the program ID “A00001”, the total number of views, the number of views in “Carrier A”, the number of views in “Carrier B”, the number of views in model “A0001”. The transition of is displayed in a graph. In addition, a graph in which the vertical axis of the graph is the ratio of the number of views to the number of viewable terminals (= viewing number / number of viewable terminals) and the ratio of the number of views to the program capacity (= viewing number / program capacity) is also displayed. Can do.

In the above embodiment, the log generation unit 34e of the distribution server 34 generates log data at the time of transmission of all program division data, but the detection unit 34c performs program division corresponding to a predetermined part of the program. Log data may be generated only when data is transmitted. In this case, the distribution server 34 stores a marker, which is information for identifying a predetermined part of the program, in a corresponding part in the program content data. The predetermined part of the program can be, for example, a part where a certain scene or image of a movie is displayed or a part where a certain song flows. The log generation unit 34e of the distribution server 34 includes information for identifying the part of the program corresponding to the marker only when it is detected that the marker is included in the program division data transmitted by the detection unit 34c. Generate log data. As a result, the aggregation processing unit 37d of the viewing information management server 37 causes the ratio of the number of views to the total number of views for each part of each program, the number of views by carrier, the number of views by model, the number of views by model series, the number of viewable terminals Viewing information such as information on the ratio of the number of views to the program capacity is generated.
The marker may be information for identifying a program. In this case, when the log generation unit 34e of the distribution server 34 detects that the program division data including the marker is transmitted, the log generation unit 34e generates log data including information for identifying the program corresponding to the marker. Thereby, the aggregation processing unit 37d of the viewing information management server 37 allows the total viewing number for each program, the viewing number by carrier, the viewing number by model, the viewing number by model series, the ratio of the viewing number to the number of viewable terminals, the program capacity Viewing information such as information on the ratio of the number of viewings to

  In the content distribution system 1 according to the above-described embodiment, program content data is transmitted from the distribution server 34 to the mobile phone terminal 10 via the network 50 and the mobile communication network 51, but distributed via the IP network. The present invention can also be applied to a distribution system that distributes content data from a server to a content reproduction terminal such as a personal computer. In this case, the session between the distribution server and the content reproduction terminal may be maintained without transmitting a distribution request from the content reproduction terminal every predetermined time. In this case, once the content reproduction terminal transmits a distribution request, it is not necessary to transmit a distribution request from the content reproduction terminal until the content reproduction terminal completes transmission of content data from the distribution server. The distribution server sequentially transmits the divided data from the divided data requested by one distribution request. The distribution server may sequentially transmit other content data after the transmission of the content data corresponding to the requested divided data is completed. At the time of transmission of the divided data, the distribution server generates log data by the same procedure as the distribution server 34 described above and writes it in the log file. Alternatively, the distribution server generates log data including information for identifying the content portion corresponding to the marker or the content itself only when the divided data having the marker corresponding to the content portion or the content itself is transmitted. Also good. A viewing information management server is provided for each program and each divided data, or for each part of each content, or for each program, the total number of viewings, the number of viewings by carrier, the number of viewings by model, the number of viewings by model series, the terminals that can be viewed Viewing information such as the ratio of the number of views to the number and the ratio of the number of views to the program capacity is generated.

  According to the above embodiment, in the program based on the log when the distribution server 34 actually transmits the program division data to the mobile phone terminal 10 instead of the number of the mobile phone terminals 10 that have established connection with the distribution server 34. Since the number of views for each predetermined part can be totaled, when the playback start time and end time of the program are different in each mobile phone terminal 10 due to transmission delay or the like, or within the range of time in which the same program division data exists Even if it may be transmitted to the mobile phone terminal 10, the number of views for each predetermined part of the program can be easily and appropriately tabulated. For example, by setting a predetermined part of a program as a part where a copyrighted image or music is transmitted, the number of views of the copyrighted image or music can be totaled, and the contents provider can be counted. Can be used for reporting the number of viewers of the video, calculating the amount paid for the copyright of the content, and the like.

  The above-described authentication server 31, CM distribution server 32, management server 33, distribution server 34, member information management server 35, and viewing information management server 37 may be configured by one device or a plurality of devices. Any of these servers may be configured by a single device.

  In the above-described embodiment, the recording apparatus 40 is managed by a content distribution company that distributes content data.
