Patent number: 7599600Abstract: The title of a program with a recording duration longest among all recording durations is recorded as the program title of a relevant program file. Thereby, even when a user has performed an operation to record a program on a hard disk recorder by a method other than a timer recording, the program title of a program that is most likely to be a program a user really desires to record can be recorded as the program title of a program file created by the recording. Accordingly, a DTV or a STB can display on its display appropriate program titles in a program file list at the time of playback of a previously recorded program.Type: GrantFiled: August 23, 2005Date of Patent: October 6, 2009Assignee: Funai Electric Co., Ltd.Inventors: Masaki Okazaki, Masahiro Matsuda
