Measuring audience viewership of online live broadcast
Method and apparatus for measuring an audience viewership of an online live broadcast are provided. Code information included in live broadcast data is received from the encoding server or the media server, transmission information of the live broadcast data to the client is received from the media server, the transmission information is compensated using the code information, and the audience viewership of the online live broadcast is computed using the compensated transmission information. It is possible to obtain the accurate viewership of an online live broadcast and to obtain the accurate viewership of the online live broadcast even when users erroneously access a web page or intentionally access the web page to increase the number of page views.
1. A method of measuring an audience viewership of an online live broadcast program in a rating server of an online live broadcast rating measuring system, the online live broadcast rating measuring system including a client, an encoding server, a media server, and the rating server, comprising:
(a) receiving code information included in live broadcast data from the encoding server or the media server;
(b) receiving transmission information of the live broadcast data to the client from the media server;
(c) compensating the transmission information using the code information; and
(d) calculating an audience viewership of the online live broadcast program using the compensated transmission information.
2. The method of claim 1 , where the code information is one of capturing time information representing time at which an image capturing device captures a scene to generate live broadcast data, encoding time information representing time at which the live broadcast data is encoded by the encoding server, and time information representing time at which the encoding server transmits the live broadcast data to the media server.
3. The method of claim 1 , wherein the transmission information includes information representing time at which the media server transmitted the live broadcast data to the client.
4. The method of claim 1 , wherein the transmission information includes at least one of a transmission rate, transmission traffic information, and a length of transmission of the live broadcast data.
5. The method of claim 1 , wherein receiving the transmission information comprises receiving reproduction information of the transmitted live broadcast data from the client.
6. The method of claim 5 , wherein calculating the audience viewership of the online live broadcast program comprises calculating the audience viewership of the online live broadcast program further using reproduction information of the live broadcast data.
7. The method of claim 5 , wherein the reproduction information of the live broadcast data includes at least one of reproduction time information and reproduction method information of the live broadcast data in the client.
8. An apparatus for measuring an audience viewership of an online live broadcast program in an online live broadcast rating measuring system, the online live broadcast rating measuring system including a client, an encoding server, and a media server, the apparatus comprising:
a code information receiver configured to receive code information included in live broadcast data from the encoding server or the media server;
a transmission information receiver configured to receive transmission information of the live broadcast data to the client from the media server;
a time information compensator configured to compensate the transmission information using the code information; and
a rating calculator configured to compute an audience viewership of the online live broadcast program using the compensated transmission information.
9. The apparatus of claim 8 , wherein the code information is one of capturing time information representing time at which an image capturing device captures a scene to generate live broadcast data, encoding time information representing time at which the live broadcast data is encoded by the encoding server, and time information representing time at which the encoding server transmits the live broadcast data to the media server.
10. The apparatus of claim 8 , wherein the transmission information includes information representing time at which the media server transmitted the live broadcast data to the client.
11. The apparatus of claim 8 , wherein the transmission information includes at least one of a transmission rate, transmission traffic information, and a length of transmission of the live broadcast data.
12. The apparatus of claim 8 , wherein the code information receiver and the transmission information receiver are included in a communication unit of the apparatus, and wherein the communication unit further receives reproduction information of the transmitted live broadcast data from the client.
13. The apparatus of claim 12 , wherein the rating calculator is configured to compute the audience viewership of the online live broadcast program further using reproduction information of the live broadcast data.
14. The apparatus of claim 12 , wherein the reproduction information of the live broadcast data includes at least one of reproduction time information and reproduction method information of the live broadcast data in the client.
15. The apparatus of claim 8 , wherein the apparatus is included in the media server.
16. A computer-readable storage medium having stored thereon instructions, when executed by a processor in a rating server of an online live broadcast rating measuring system including a client, an encoding server, a media server, and the rating server, cause the processor to:
(a) receive code information included in live broadcast data from the encoding server or the media server;
(b) receive transmission information of the live broadcast data to the client from the media server;
(c) compensate the transmission information using the code information; and
(d) compute an audience viewership of the online live broadcast using the compensated transmission information.
