System and method for accurate measuring transmission effect of P2P stream media netwrok for video / audio programs

[0067] Example 1 Measuring the number of listeners/viewers of Internet audiovisual programs

[0068] The use of P2P streaming media technology to broadcast audiovisual programs on the Internet is bound to face the phenomenon of asynchronous presentation. How to accurately count the number of viewers of each advertisement and program is a problem faced by all media units and other social organizations. The following methods can be adopted:

[0069] 1. The streaming media distribution terminal sends a message to the National Time Service Center via the Internet to obtain network time services, that is: you can first write down the local time T1, and send the ASCII string ">XXX.XXX.XXX.XXX" to the National Time Service Center server. ", that is, the tag code ">" plus the IP address of the streaming media distribution terminal computer. After the national time service center server receives it, it obtains the time code at this moment and sends it to the streaming media distribution terminal. The streaming media distribution terminal receives the time stamp sent by the server After the code "<", write down the time T2, and then solve the server time code T3, ignoring the server time-consuming, the time difference between the server and the user's computer is T3-(T1+T2)/2, and the streaming media distributor can adjust the distributor accordingly The computer time is almost at the same time as the National Time Service Center (the computer time of the distribution terminal may not be adjusted);

[0070] 2. The streaming media distribution terminal is responsible for encapsulating the streaming media data of the audiovisual program into a splittable streaming media data format (slice) used by the P2P system, and calculates the time when each slice is split according to the accurate time value obtained in the previous step , And then encapsulate this time information into streaming media slice data, that is, add a time stamp (or timestamp) to each slice, and then publish it to the Internet;

[0071] 3. The client obtains streaming media slice data with timestamps from the streaming media distributor or other clients via the Internet;

[0072] 4. The client separates the timestamp of each slice, and then combines the slices to present the picture and sound of the audiovisual program;

[0073] 5. The client terminal collects the timestamp and converts it into a data recording file, which is recorded in a unit of one second for each broadcast. The data recording file can take the following form: only the presentation time such as 09:15:22, etc. is recorded; If the picture is displayed for less than 1 second but greater than 0.5 second, it is regarded as 1 second, and less than 0.5 seconds is regarded as not playing at that time; (You can also only record the client entry and exit time)

[0074] 6. The client terminal will pass the interval time at each time point separated by a fixed length of time, such as 9:00, 9:10, 9:20, 9:30... etc. at a fixed time of 10 minutes apart The data record file and the IP address of the client are sent to the client viewing record server, which aggregates all the received data, and after calculation, the number of listeners/viewers corresponding to each time stamp in the past interval time period can be obtained. As shown in Table 1:

[0075] Time point

[0076] Table 1

[0077] For example, Table 2 is used to retrieve and broadcast the program list;

[0078] Starting time

[0079] Table 2

[0080]The time period of 09:21:31-09:21:35 is the "Golden Liufu Liquor Advertisement". The sum of all viewers corresponding to this period is divided by the duration (5 seconds) to get the average of the advertisement. The number of viewers, (280005+28004+28003+28002+28001)/5=28003; replaced by the standard statement in the communication or advertising media industry, that is, the number of viewers of the advertisement is 28003. This fully complies with the measurement standards commonly used in the advertising media industry, and realizes the accurate measurement of the effect of p2p streaming media for audiovisual programs.

[0081] Example 2 Measure the number of listeners/viewers of audiovisual programs on IPV6 mobile phones

[0082] The Internet protocol is called the TCP/IP protocol. The IP protocol widely used in our country is the fourth-generation Internet protocol, referred to as IPV4, while IPV6 stands for the sixth-generation Internet protocol. The rapid development of the global Internet has led to a shortage of IP address resources. The existing Internet protocol IPV4 has exposed deficiencies in address space, end-to-end IP connectivity, service quality, network security, and mobility. And IPV6 has a sufficiently wide address space that expands from the 32BIT address of IPV4 to 128BIT. IPV6 can meet the security, quality and mobility requirements of the next-generation voice, data, and video integrated communication network. IPV6 mobile phones use P2P streaming media technology to play audio-visual programs, and they are bound to face the phenomenon of asynchronous presentation. In order to accurately count the number of viewers of each advertisement and program, the following methods can be adopted:

[0083] 1. The streaming media distribution terminal of the audiovisual program sends information to the national time service center through IPV6 to obtain network time service, that is: you can first write down the local time T1, and send the ASCII code string ">XXX.XXX to the national time service center server." XXX.XXX", that is, the tag code ">" plus the IP address of the streaming media distribution terminal computer. After the national time service center server receives it, it will get the time code at this moment and send it to the streaming media distribution terminal, and the streaming media distribution terminal will receive it from the server After the time mark code "<", write down the time T2, and then solve the server time code T3, ignoring the time consumption of the server, the time difference between the server and the user's computer is T3-(T1+T2)/2, and the streaming media distribution terminal can use this Adjust the computer time of the distribution terminal to be basically at the same time as that of the National Time Service Center;

[0084] 2. The streaming media distribution terminal is responsible for encapsulating the streaming media data of the audiovisual program into a splittable streaming media data format (slice) used by the P2P system, and time stamps or timestamps on each slice, and then releases to the IPV6 network;

[0085] 3. The IPV6 mobile phone obtains streaming media slice data with time stamps from the streaming media distribution terminal or other clients through the network;

[0086] 4. The IPV6 mobile phone separates the timestamp of each slice, and then combines the slices to present the sound of the audiovisual program;

[0087] 5. The IPV6 mobile phone collects the time stamp and converts it into a data recording file, which is recorded in a unit of one second during the broadcast. The data recording file can take the following form: only the presentation time such as 09:15:22, etc. is recorded; for the end If the picture is displayed for less than 1 second but greater than 0.5 second, it will be regarded as 1 second, and if it is less than 0.5 seconds, it will be regarded as no playback at that time;

[0088] 6. IPV6 mobile phones can be at each time point separated by a fixed length of time, such as 9:15, 9:30, 9:45, ... etc. at a fixed time of 15 minutes apart, the data in the past interval The record file and the client's IP address are sent to the client's viewing record server, which aggregates all the received data, and after calculation, the number of listeners/viewers per second in the past interval can be obtained.

[0089] According to the above method to count the number of listeners/viewers, it is automatic, convenient, low cost, and efficient, and it is consistent with the main statistical caliber of the current radio and television listening ratings—in seconds, which is convenient for advertising companies and advertisers to apply this result To measure the effect of communication and guide the next period of advertising strategy; at the same time, because it has the same measurement caliber as the current radio and television ratings survey results, it will be beneficial to conduct a comparative study of the effects of radio and television media and online media.
