摘要： Recording-capable receiver 3 includes broadcast receiving unit 302 for receiving video/audio stream; storage unit 305 for storing the video/audio stream and storage time information; playback unit (decoder 306, video output unit 307, audio output unit 308) for playing the video/audio stream stored; control unit 309 for extracting the storage time information corresponding to the video/audio information in the video/audio stream played back; and communication unit 310 for transmitting the storage time information extracted to information management server 2 and for receiving the pertinent information. The information management server 2 includes storage unit 203 for storing pertinent information to specific video/audio information along with time information; retrieval unit 204 for extracting appropriate pertinent information by comparing the storage time information transmitted from the communication unit 310 with the time information stored in the storage unit 203; and communication unit 201 for transmitting the pertinent information extracted to the recording-capable receiver 3.
