In the above described manner, header list generation unit 205b generates the header list 281 shown in Figure 13 A.

＜other modifications 〉

As described in previously, the present invention relates to the program recording apparatus of the header list that is used for recorded program and generates recorded program.

The invention is not restricted to above program recording apparatus 100 or the program recording apparatus of describing as instantiation 200, but can make following modification.

(1) in the above-described embodiment, program recording apparatus 100 generates the title with predetermined byte number, and program recording apparatus 200 generations have the title that is less than for the byte of every kind of predetermined maximum number of byte of record format.Yet, can be according to the GUI design of customization, determine the length (byte number) of the title that in header list, shows.

For example, program recording apparatus can be stored the GUI custom program.The GUI custom program is a computer program, receives the GUI design of being selected by the user, and realizes the GUI design of selection.Suppose that for example the user can select one of " children GUI " and " adult GUI " to design as GUI.

Figure 16 is illustrated in the flow chart of carrying out the part operation of program recording apparatus in the GUI custom program.The program recording apparatus record series program that is operating as described herein, and the operation of the heading message of the program of generation record.

Program recording apparatus receives the selection (step S301) of GUI design.If the GUI that selects is designed to " adult GUI " (" adult " among the step S302), program recording apparatus is deleted total character string from the title of series performance, and extracts 32 bytes (step S303) from the remainder of title, and forwards step S306 to.

If the GUI that selects is designed to " children GUI " (" children " among the step S302), program recording apparatus is deleted total character string from the title of series performance, and extracts 16 bytes (step S304) from the remainder of title.Program recording apparatus then increases the set width and the height (step S305) of the title that extracts.In other words, after increasing, the font of " children GUI " on width and height greater than " adult GUI ".Program recording apparatus then generates a heading message, comprises the title (step S306) of broadcasting date, channel number and extracting.

When selecting " children GUI ", generate the header list 291 shown in Figure 17 A.When selecting " adult GUI ", generate the header list 292 shown in Figure 17 B.Header list 291 has bigger font size and character still less than header list 291.

Here the GUI design that should note every type and also can differ from one another on font type not only on the width and height of font, and can use polytype GUI design, is not limited to " children GUI " and " GUI is grown up " two kinds.

If the GUI custom program is stored among DVD-RAM or the BD-RE, program can be recorded among DVD-RAM or the BD-RE.Then, when being the program generation header list that is recorded among DVD-RAM or the BD-RE, program recording apparatus can read the GUI custom program and carry out it from DVD-RAM or BD-RE, and according to the GUI design of being selected by the user, determines to be presented at the byte number of the title in the header list.
