The program attribute information is constituted by program attribute names and program attribute retrieval conditions. The video recording and reproducing apparatus 11 causes a display apparatus 12 to display a list of the program attribute names. The user selects a program attribute name, to which a program that the user wishes to reserve for recording seems to be most closely related, out of this list. The video recording and reproducing apparatus 11 compares retrieval conditions corresponding to the selected program attribute name and EPG information and, when the retrieval conditions are satisfied, records a program represented by the EPG in a recording reservation list. It is possible to apply the invention to a hard disk video recorder.Type: ApplicationFiled: July 23, 2003Publication date: April 6, 2006Applicant: SONY CORPORATIONInventors: Kensuke Ohnuma, Hitoshi Kimura, Shinichi Wakai, Keiichi Yoshioka, Shingo Utsuki, Hidetoshi Ichioka
