摘要

In a method of receiving augmenting content, broadcast content and augmenting content are received from a broadcast content providing apparatus, metadata related to the broadcast content is interpreted to check an indicator indicating such that augmenting content are applicable, and augmenting content are requested from an augmenting content providing apparatus by using access information of the augmenting content providing apparatus. Thereafter, augmenting content are received from the augmenting content providing apparatus, and augmenting content received in the augmenting content receiving step are synchronized with the broadcast content and output to a temporal/spatial region corresponding to display region information included in the metadata or the display region information is transmitted to a separate output device. Thus, a viewer can conveniently receive area information-based augmenting content in the form of large capacity multimedia including a graphic image or video without having to perform searching.
