An information search system for searching for a desired content by using meta information sent from a broadcasting station. A receiving device issues an inquiry to a directory service server by using a meta information reference ID accompanying meta information sent from the broadcasting station to obtain a meta information group referenced by using this meta information reference ID. At the same time, the receiving device issues an inquiry to the content service server by using content location information and a keyword included in the sub-meta information in the meta information group to search for the desired content.
