An information providing system comprising a video/audio provider, a receiving apparatus and an information management server, wherein the video/audio provider is adapted to transmit to the receiving apparatus a video/audio stream in the form of programs including specific video/audio information and program sequence information which is information about a program contained in the video/audio stream, and to transmit to the information management server program frame scheduling information which is information about a program frame including the transmitting time of a program contained in the video/audio stream, and wherein the information management server is adapted to manage pertinent information to specific video/audio information contained in a video/audio stream, and to provide the pertinent information in response to an inquiry from the receiving apparatus, wherein the receiving apparatus comprises: a receiving unit adapted to receive the video/audio stream from the video/audio provider; a data storage unit adapted to store the video/audio stream received by the receiving unit; a time information storage unit adapted to store, as record program frame information, time information corresponding to program sequence transmitted from the video/audio provider; a playback unit (307, 308) for playing back the video/audio stream stored in the data storage unit; an extracting unit adapted to extract from the time information storage unit the record program frame information corresponding to the programs in the video/audio stream played back by the playback unit (307, 308); a device adapted to store a playback history which is history information about the playback of a record program and comprises the record program frame information, and a receiving apparatus side communication unit adapted to transmit the record program frame information extracted by the extracting unit to the information management server for inquiring about pertinent information to the specific video/audio information on a program played back, and wherein the information management server comprises: a pertinent information storage unit adapted to store the program frame scheduling information received by the video/audio provider and including pertinent information to the specific video/audio information along with the time information that is added to the appropriate specific video/audio information; a retrieval unit for extracting appropriate pertinent information from the pertinent information storage unit by comparing the record program frame information transmitted from the receiving apparatus side communication unit with the time information stored in the pertinent information storage unit; and a server side communication unit adapted to transmit the pertinent information extracted by the retrieval unit to the receiving apparatus in response to an inquiry from the receiving apparatus, wherein the receiving apparatus side communication unit is adapted to receive the pertinent information corresponding to the record program frame information from the information management server. a receiving unit adapted to receive the video/audio stream from the video/audio provider; a data storage unit adapted to store the video/audio stream received by the receiving unit; a time information storage unit adapted to store, as record program frame information, time information corresponding to program sequence transmitted from the video/audio provider; a playback unit (307, 308) for playing back the video/audio stream stored in the data storage unit; an extracting unit adapted to extract from the time information storage unit the record program frame information corresponding to the programs in the video/audio stream played back by the playback unit (307, 308); a device adapted to store a playback history which is history information about the playback of a record program and comprises the record program frame information, and a receiving apparatus side communication unit adapted to transmit the record program frame information extracted by the extracting unit to the information management server for inquiring about pertinent information to the specific video/audio information on a program played back, and wherein the information management server comprises: a pertinent information storage unit adapted to store the program frame scheduling information received by the video/audio provider and including pertinent information to the specific video/audio information along with the time information that is added to the appropriate specific video/audio information; a retrieval unit for extracting appropriate pertinent information from the pertinent information storage unit by comparing the record program frame information transmitted from the receiving apparatus side communication unit with the time information stored in the pertinent information storage unit; and a server side communication unit adapted to transmit the pertinent information extracted by the retrieval unit to the receiving apparatus in response to an inquiry from the receiving apparatus, wherein the receiving apparatus side communication unit is adapted to receive the pertinent information corresponding to the record program frame information from the information management server.
