PERSONAL DIGITAL ASSISTANT, INFORMATION SYSTEM AND METHOD FOR ACQUIRING INFORMATION

PROBLEM TO BE SOLVED: To provide a personal digital assistant capable of reviewing contents flowing in media broadcasting from the head of the contents during the viewing of the media broadcasting. SOLUTION: A control part 109 extracts an ADTS block decoded by a decoder 103b in a reproduction part 103 and transmits the extracted ADTS block to a musical composition retrieving server 500 as request data through a radio part 102 (step S102). When the personal digital assistant 100 receives musical composition information from the musical composition retrieving server 500, a storing position calculation part 109b calculates which block out of ADTS blocks in a buffer 103a is to be stored in a storage part 106 (step S103). When a start position (ADTSα) and an end position (ADTSβ) are determined in a step S104, a storage execution part 109c starts the storage of data in the storage part 106 from the ADTSα in the buffer 103a (step S104) and ends the storage of data after completion of storage up to the ADTSβ (step S106).
