The prior art described above uses an IEEE as an interface method for video information and control data.
The one according to E1394 is taken up. But,
It does not describe how to actually control it, and no TV receiver that controls it has yet been announced.

[0004] In the future, as the number of TV broadcast channels increases and the information transmitted becomes diversified, it is considered that a control method for receiving and recording the broadcasts will become more important.

[0005] For example, to give a specific example, at the present time, when making a recording reservation for a VTR, when making a recording reservation for a program following a baseball broadcast, or when extending a baseball broadcast, the recording reservation time is set. It is necessary to set a wide time range, and it is troublesome to set a recording time, and it is necessary to secure a video tape capable of extra recording in terms of time. If this extends to a plurality of programs, more troublesome recording reservations must be considered.

[0006]

Hereinafter, an example of the recording reservation setting in the control unit 9 and the recording control algorithm based on the recording information detected by the recording information detecting unit 4 in the present embodiment will be described.

First, FIG. 2 shows an example of a recording reservation setting algorithm in the control section 9. Reference numerals 20a to 20i in FIG. 2 indicate the order of processing, and the processing is performed as follows in alphabetical order.

20a: From the reservation setting terminal 8 to the recording reservation unit 6
Set a recording reservation for the program. The contents of the reservation are a channel number, a recording start time, and a recording end time.

20b: At the point in time when the input of the contents of the reservation is completed, the recording reservation section 6 confirms whether or not there is a time overlap with other already set reservation settings. Is displayed on the screen.

20c: Similarly, the recording reservation section 6 compares the set recording time with the recordable time obtained from the recording remaining amount detecting means 14 when the input of the reservation contents is completed,
If the recordable time is short, information to that effect is displayed on the screen.

20d: The recording shift permission / prohibition is extended and set in the shift permission / prohibition setting section 7.

20e: When the shift permission is set, it is confirmed whether or not there is a time overlap with another already set reservation setting, and if there is a time overlap, information indicating the same is displayed on the screen.

20f: The extension of the recording and the extension time are set in the extension / shift availability setting section 7.

20g: When the extension is set, it is checked whether or not there is a time overlap with other already set reservation settings. If there is a time overlap, information indicating that is overlapped is displayed on the screen.

20h: Similarly, when the extension is set, the total time of the set recording time and the extension time is compared with the recordable time obtained from the recording remaining amount detecting means 14. Is displayed on the screen.

20i: Recording reservation completed.

The reservation setting is performed as described above. In this algorithm, the recording shift permission / prohibition setting 20d and the reservation overlap detection 20e may be performed after the tape remaining amount check 20h, and the order of the reservation overlap detection and the remaining amount check may be either first.

Next, an example of the flow of actual recording time shift control processing will be described with reference to FIG.

21a: When the recording information detecting section 4 detects no program shift, normal control is performed in accordance with the time set in the recording reservation section 6, and when a shift is detected, control is performed as in 21b.

21b: If the recording information detection unit 4 detects that a program shift has been made, if the setting of the extension / shift permission / inhibition setting unit 7 is set to shift-inhibited, normal control is performed according to the time set in the recording reservation unit 6. If shift is set, the recording time shift control is performed according to the shift information.

Next, an example of the flow of the actual recording time extension control process will be described with reference to FIG.

22a: When the recording information detection unit 4 detects that the program is not extended, the normal control is performed according to the time set in the recording reservation unit 6, and when the extension is detected, the control is performed as in 22b.

22b: When the recording information detecting section 4 detects that the program is to be extended, if the setting of the extension / shift enable / disable setting section 7 indicates that the program is to be extended, normal control is performed according to the time set in the recording reservation section 6. If the extension is set, control is performed as in 22c.

22c: Control is performed so as to extend the recording time according to the extension time detected by the recording information detection unit 4. At this time, if the extension information (extension time) detected by the recording information detection unit 4 is longer than the recordable time of the recording medium, information to that effect is displayed on the screen.

In the example of the embodiment shown in FIG. 1, the recording control is performed by transmitting the recording control to the recording device 15 together with the image information through the I / F section 10 as described above. Further, in the above operation example, the case of recording time shift or extension is described separately, but according to the above-described control, control can be performed even if the recording time shift and extension occur simultaneously.

Next, FIG. 5 shows an example of another embodiment of the video information terminal device according to the present invention. 1 have the same functions as those in FIG. A terminal 32 is an output terminal of a recording control signal, a terminal 33 is an information input terminal of a recordable time of the recording device 15b, and 15b is a recording device having a recordable time detecting unit 14.

In one example of this embodiment, the image information is output from the terminal 30 and is supplied to the display device 1 via the recording device 15b.
Lead to 1. In this connection, the terminal 30 connects the recording device 1
There is no problem in the present invention even if both are connected in parallel to both the display device 5b and the display device 11.

Next, the operation of the control unit 9 is the same as that described with reference to FIG. 1, and recording control is performed via the terminal 32. In this case, information on the recordable time of the recording device 15b is transmitted to the terminal 33.
Get from.

In this configuration, the I / F unit 1 shown in FIG.
Although the image information and the recording control are performed using different terminals without using 0 and 12, the same effect as in FIG. 1 can be obtained.

Next, FIG. 6 shows an example of another embodiment of the video information terminal device according to the present invention. Also in FIG. 6, those having the same reference numerals as those in FIGS. 1 and 5 have the same functions. In the present embodiment, the control unit 9 sets the recording reservation time without using the information on the recordable time and controls the recording unit 13. In this case, the recording reservation setting in the recording reservation section 6 and the extension / shift enable / disable setting section 7 may omit the recording medium remaining amount confirmation 20c, 20h of the setting shown in FIG. 2, and in the recording extension control shown in FIG. Check remaining medium 22
This can be realized by omitting c. With such a configuration, it is possible to shift or extend the recording time even if the recording device does not have the recording time detection function.

In the example of the embodiment shown in FIGS. 1, 5 and 6, the recording means 15 may be provided as a function inside the video information terminal device or may be connected to the outside. However, the type does not need to be specified. As a means for transmitting the recording information of the program, it is conceivable that the recording information is transmitted as a part of information by text multiplex broadcasting. In that case, the recording information detection unit 4 can be realized as a part of the function of the character multiplex decoder.

[0042]

According to the present invention, it is possible to record a program whose broadcast time has been extended or shifted without setting a reservation time in consideration of the fact that the broadcast time is extended or shifted at the time of recording reservation. Usability is improved. At the same time, there is no need to prepare a recording medium with sufficient recording time.
