The present invention relates to an internet protocol broadcast service, and more particularly, to an internet protocol broadcast service receiving terminal, a server, and a viewer rating research method using the same.

Broadcasting using the Internet refers to a service that provides video or audio data, which is multimedia data, to users through real time or video on demand (VOD) through the Internet. At this time, Internet Protocol Television (IPTV) uses the Internet to provide digital television services to consumers.

On the other hand, audience rating survey methods used in terrestrial broadcasting, cable broadcasting and satellite broadcasting include diary surveys that allow viewers to fill out and fill out questionnaires, interview surveys through visits or telephone interviews, meter surveys and people that automatically record the machine. Survey using a meter.

The survey using the people meter is a research method in which a people meter device is installed on a television receiver for a certain piece of furniture called a panel selected by a sampling method, and the viewer information is analyzed by user interference through a mechanical device in the form of a remote controller. . At this time, the viewer rating participant participates in the rating test through the remote controller connected to the people meter device when the viewer starts watching the broadcast, and then the channel change is automatically recorded in the people meter device. The viewer rating information recorded in the people meter is sent to the viewer rating research center using a telephone line.

However, the people meter is complicated and expensive to install. In addition, the continued and faithful cooperation of the panel is absolutely required. Furthermore, since the limited number of panel households reflects the overall viewer rating, there is a problem in that the viewer ratings vary greatly depending on the distribution and number of panels and the method of survey.

In the viewer rating research method using a people meter, there are two methods of distinguishing a viewing channel from a large channel detection method and a picture matching method in which a part of a television screen is stored and compared with the corresponding channel. In analog broadcasting, audience rating can be investigated by frequency detection, but digital broadcasting uses a picture matching method that does not use frequency division as a reference because multiple channels can be performed at the same frequency.

However, for the IPTV viewership survey using IP (Internet Protocol) multicast for broadcast data transmission, a new channel classification method and a viewership survey method are required. In this case, when applying the picture matching technology, there is a problem of inheriting the high cost and the disadvantages of using the above-described people.
