An apparatus for providing an augmented broadcasting service and an apparatus for receiving the augmented broadcasting service in a hybrid broadcasting environment. The apparatus for providing the augmented broadcasting service includes: a real-time data provider configured to provide real-time data through a first transmission network; an augmented content provider configured to provide augmented content through a second transmission network, wherein the augmented content is to be synchronized with the real-time data; and a multiplexer configured to multiplex the real-time data, the augmented content metadata and timing information for synchronization between the real-time data and the augmented content metadata, and output resulting data.

Apparatuses for providing and receiving augmented broadcasting service in hybrid broadcasting environment

Provided are an analysis method and system for audience rating and advertisement effects based on viewing behavior recognition including a method of recognizing a viewer on the basis of image recognition through a camera and efficiently collecting data and a method of transmitting collected data on the basis of viewer recognition to an audience rating and advertisement effect measurement server. The present invention includes a viewing behavior measurement device configured to receive a viewer image obtained by imaging one or more viewers who are viewing broadcast content, recognize the one or more viewers from the received viewer image to generate viewing behavior information, and deliver the generated viewing behavior information, and an advertisement effect measurement server configured to analyze an advertisement effect for each viewer on the basis of the received viewing behavior information and generate and deliver an advertisement effect measurement result.
