<p>The present invention relates to a technology for more accurately calculating TV audience ratings in an Internet environment. The audience rating survey apparatus mirrors packets transmitted from a survey subject apparatus over an Internet network, extracts packets including VOD broadcast program selection information and channel change information from the mirrored packets to collect audience rating data, and allows a remote control signal of the survey subject apparatus to be applied only through the audience rating survey apparatus, thereby easily synchronizing the survey subject apparatus with the audience rating survey apparatus.</p> |
