Thus, in the above preferred embodiment, the central office device receives the first request message of a certain terminal, and determines whether the terminal has the right to play the program channel, and searches the database server for the program. The permission of the channel, if the found permission is the permission permission or the preview permission, it is determined that the terminal has the right to play the program channel, and if the found permission is the permission permission, it is determined that the terminal does not have the right to play the program channel. Preferably, as shown in FIG. 2, the information statistics server 20 includes: an extraction module 202, a first statistics module 204, a second statistics module 206, a third statistics module 208, and a fourth statistics module 209. The extracting module 202 is configured to extract, from the database server 30, the viewing information corresponding to the statistical item in the viewing information of the terminal; for example, when the statistical item is the program rating, the terminal needs to be taken out from the database server. The time of a program, when the statistical item is the time-of-view rating, it is necessary to take out the time when the terminal watches the channel M in the time period [S, E] from the database server. When the statistical item is the channel preview rate, it needs to be from the database. In the server, take out the number of times the terminal previews the channel M and previews the number of all channels. When the statistical item is the unprivileged request rate, the number of times the terminal requests the unprivileged channel M and requests all are taken out from the database server. The number of times of the unprivileged channel; the first statistic module 204 is set to calculate the rating of the program P according to the following formula when the statistical item is the program rating:

The rating of the program P (%) = ~ —— -xl 00% , where "represents the number of nx {E - S" of the extracted terminal, ; represents the time when the first terminal of the w terminals plays the program P, E And S are respectively the end time and the start time of the program P, i = 1, . , n; the second statistic module 206 is set to calculate the time-of-day rating of the program channel M according to the following formula when the statistical item is the time-of-day rating The value is:

The time period rating (%) of the program channel M = ~ —— -xl 00% , where w represents the number of terminals from which nx {E - S is extracted, and represents the ith terminal of the n terminals to play the program channel M Time, E, S are the end time and start time of the time period to be counted respectively, i = 1, . , n; The third statistical module 208 is set to calculate the program channel according to the following formula when the statistical item is the channel preview rate The value of M's preview rate is:

The preview rate of the program channel M (%) =^ ~ x l 00% , where "expresses the extracted

The number of terminals for preview permission of program channel M, ^ indicates that the i-th terminal in n terminals is certain The number of times the program channel M is previewed during the time period, and 4 indicates the number of times the third terminal of the w terminals previews all the program channels in a certain period of time, = 1, ..., "; fourth statistical module 209, set to be statistical When the item is a non-privileged request rate, the value of the non-privileged request rate for calculating the program channel 按照 according to the following formula is:

Obviously, after the statistics of the above statistical items are obtained, the results of various statistical items can be output for reference. The preferred embodiment can flexibly count various types of viewing information according to various requirements, and fully realize automatic counting by the system according to needs, can improve data accuracy, reduce cost and have higher precision. In addition, the preferred embodiment enriches the existing viewing statistics, and can not only count the program rating and the channel rating, but also conveniently count the user senses on the on-demand statistics of the channels with only preview permission and no permission. Programs of interest can be customized to be targeted. Preferably, the extracted terminals are terminals that meet some or all of the conditions of the statistical items in each terminal. In this way, statistics can be collected from the entire user group in actual demand, and statistics can be performed in a similar manner. When the statistics are collected from the entire user group, the accuracy and accuracy of the data are further improved. As shown in FIG. 3, in actual implementation, the terminal 40 as a user's viewing device is composed of a television set and a set top box, and is connected to the access central office device through the access terminal device. The user can watch the IPTV at the home using the terminal, and the terminal 40 exists in every home user, and some even have multiple. The main role of the terminal in the system is to initiate viewing (ie, sending the first request message) and terminating the viewing (ie, sending the second request message). Accessing the central office equipment and the access terminal equipment, followed by the television system, a large number of terminals accessing the central office side through the access terminal equipment, and the central office side includes the access office equipment, the database server, and the information The statistics server, these three communicate with each other through the network. FIG. 4 is a diagram showing a method for collecting viewing information of an IPTV system according to an embodiment of the present invention. As shown in FIG. 4, the method includes the following steps: Step S402: The access office device receives a first request message from each terminal for requesting to enter a program channel. Step S404, accessing the central office device according to the first A request message records the viewing information of each terminal. In step S406, the information statistics server extracts the viewing information corresponding to the statistical item to be counted from the recorded viewing information, and uses the extracted viewing information to obtain the value of the statistical item. Preferably, as shown in FIG. 5, step S404 includes the following steps: Step S502: The accessing end office device finds that a terminal requests to join a certain channel, that is, receives a request from a certain terminal to join a certain program channel. a request message, where the first request message includes terminal information and program channel information; Step S504, the access office device determines the authority of the terminal indicated by the terminal information in the first request message, and the rights may be three : Allow, preview or not allow, when the permission is allowed or previewed, it is determined that the terminal has the right to play the program channel indicated by the program channel information, and the process goes to step S506, and when the permission is not allowed, it is determined that the terminal does not have Playing the rights of the program channel, and proceeding to step 4, S208; Specifically, since the rights of each terminal to different program channels are stored in the operation and maintenance database of the database server in advance, the accessing end device is in the opposite terminal. When the authority is judged, it can be searched from the operation and maintenance database. Step S506, the accessing end device records the terminal information, the channel to be viewed, the terminal's right to view the channel (ie, permission or preview), and the terminal views the start time and the end time of the channel. Then, the information is recorded by the step 4 S510; wherein, the end time is obtained by the access office device by the subsequently received second request message from the terminal for requesting to leave the program channel, and the default is received. The time of the second request message is the end time. In actual implementation, when it is judged that the terminal has the permission to play the channel, a log may be generated at a certain time (for example, 1 minute), and the log has the time when the log is generated, the terminal information and the program channel information, and is received. When the first request message and the second request message for leaving the channel are used, there is also a start time and an end time of the terminal broadcast; when it is judged that the terminal has the preview permission to play the channel, only when the terminal leaves the program channel A log is generated, which can also record that this is the terminal to preview the channel several times. All of these logs are called terminal viewing information. Step S508, the access office device records the terminal information, the channel information that is viewed, the terminal's right to view the channel (that is, is not allowed), and the time when the terminal starts playing the channel (this time is empty), and then the steps are performed. S510 records the information; in actual implementation, when it is judged that the terminal does not have the right to play the channel, a log is also generated, and the time when the log is generated and the permission of the terminal are not allowed. Step S510, the access office equipment stores the viewing information recorded in step S506 and step S508, and uploads the viewing information to the database server (specifically, uploads to the viewing database) after determining that the uploading condition is satisfied. The stored data information is mainly composed of the following: one is user information, which is uniquely indicated by the device identifier and the port identifier; the second is the channel for viewing, which is indicated by the IP address of the channel; the third is permission, permission, preview, and no Allow one of the three; Fourth is the start time, the time unit, which records the time when the user joins a channel; 5 is the end time, the time unit, which records the time when the user left a channel, and the permission is not allowed. Empty; in step S512, the viewing information is uploaded to the database server. There are certain policies in the access office equipment to control the uploading of the viewing information. Generally, there are two ways to control the uploading to the database server when a certain storage item (that is, the predetermined number of thresholds) is reached, if the storage is not reached. An entry, but is also uploaded to the database server when it reaches a certain time. In the process shown in FIG. 5, after the access office device uploads the recorded viewing information of each terminal to the database server, as shown in FIG. 6, the database server stores the viewing information according to the following steps: The data storage is divided into two. The process is to collect the viewing information stored in the database, and the entire system provides the data information. The other is the operation and maintenance database, which stores the relevant information of the operation and maintenance. The user information and program channel information obtained from the operation and maintenance part are stored in the process. In this database. Step S602, the viewing database receives the viewing data of each terminal uploaded by the accessing end device through the network; Step S604, the viewing database processes and processes the received viewing information. Since the obtained viewing information is relatively original data, further processing is required, one is user information, which is converted into the only user identifier in the operation and maintenance; the second is the channel to be viewed, and the IP address needs to be converted into actual channel information. Step S606, storing the processed and processed viewing information into a database, and the key index of the database is terminal information. As shown in FIG. 7, step S406 in the method shown in FIG. 4 includes the following steps: Step S702, selecting an information statistics item, which mainly includes data statistics of four types of viewing information: program rating, time-of-view rating, and channel preview rate. And the non-privileged request rate, one or more of the four statistical items may be selected for statistics; Step S704, selecting sample data, extracting the sample terminal from the database server according to the information statistical item selected in step S702 The viewing information, the channel program information that needs to be counted; the extracted sample terminal may be all terminals, or may be part of the terminal. In this way, according to different requirements, statistics can be performed from the entire user group or in a manner that is used in the same manner; Step S706, according to the information statistical item selected in step S702 and the data extracted in step S504, the calculation is performed. The information is statistically summarized and the results are output. Specifically include:

(1) Program ratings refer to the percentage of the total number of viewers (or the total number of households) who watched a program within a certain period of time (or the number of households). The n-sample terminal looks at the ratio of the weighted total time of the program P to n times the duration [S, E] of the program. Extracting n terminals, taking out the time when each terminal plays a certain program from the viewing database, and then accumulating the total viewing time of each terminal, and then the ratio of n times of the duration of the program is the rating of the program P. , Ί] for each terminal to watch the program P time, the formula is as follows:

The rating of program P (%) = ~ —— -xl 00%.

Nx (E - S) where Ί] is obtained by the time when the start time and the end time of the channel in which the terminal plays the program P fall within the duration [S, E] of the program P input in advance. (2) The time-of-day rating refers to the percentage of the total number of viewers (or the total number of households) who watched a certain channel (or the number of households) in a certain period of time. The ratio of the weighted total time at which a sampling terminal plays a certain channel to n times the duration of the period. N terminals are extracted, and the time at which each terminal watches the channel M in the period [S, E] is taken out from the viewing database, and then the viewing time of each terminal is cumulatively added, and the ratio of n times of this period is the channel. The time-of-view rate of M, the time for playing channel M for each terminal, the calculation formula is as follows:
