When a tool is selected from the program guide, the program guide is displayed.
[0029]
FIG. 10 is a flowchart showing the relationship between switching between the disk reservation mode and the main body reservation mode. First, when a disk having reservation information set for recording reservation is inserted in the apparatus main body and is in the disk reservation mode (step S40), it is determined whether or not the disk is removed (step S41), and the disk is removed. In this case, the main body reservation mode is set. When a disk reservation off operation is performed with the disk inserted (step S42), the main body reservation mode is switched. When the disk reservation off operation is not performed, the disk reservation mode is maintained.
[0030]
When the reservation mode is the main body reservation mode (step S43), when the disc on which the disc reservation is set is inserted into the apparatus main body, the mode is switched to the disc reservation mode. At this time, even if a disk without disk reservation setting is inserted, the main body reservation mode is maintained. If the disk reservation is not inserted, it is determined whether or not the disk reservation ON operation has been performed (step S45). If the disk reservation ON operation is performed, the disk reservation mode is switched. Stay in mode.
[0031]
In the above-described step S41, when all of the reserved recording on the disk has been executed, the reserved information in the disk is erased, so that the main body reservation mode is switched as when the disk is removed. It may be.
[0032]
In this way, in this example, since the disk reservation ON / OFF operation can be performed by the user's instruction via the UI 5, the disk reservation can be performed by inserting and removing the disks set for reservation one by one as in the prior art. Even without turning on / off, it is possible to improve the usability of the scheduled recording work.
[0033]
In this example, in the event of a power failure, a function is provided to know the reservation mode selection state before the power failure when the power is restored. FIG. 11 shows a display example of the GUI 9 and the main body display tube 10 when the power is restored from a power failure. First, as a state before the power failure, it is determined whether or not the disk reservation is on (step S51). The non-volatile memory 11 records whether the reservation mode before the power failure is a disk reservation or a main body reservation. When a power failure occurs, the reservation mode information at that time is read from the non-volatile memory 11. If it is a disk reservation, a disk reservation ON flag is set (step S52).
[0034]
Then, the GUI 9 displays that the disk reservation is on based on the flag information (step S53). As an example of the display content, for example, “Disk reservation is on. The reservation of the main body will not be executed until the disk reservation is disabled or the disk is replaced” is displayed. In addition, the main body display tube 11 displays “Reserve disk reservation” or the like (step S54). When the user is notified of these displays for about 5 seconds, the display may be turned off or a normal menu screen may be displayed.
[0035]
In this case, even if the user does not turn on the GUI 9 and display the reservation list or the like, the user can easily recognize the type of the reservation mode before the power failure. Can be eliminated.
[0036]
In this example, the main body display tube 11 is provided with a disk reservation LED as a display indicating disk reservation on / off, and a timer recording LED that is turned on when either disk reservation information or main body reservation information exists. I am doing so. FIG. 12 shows the lighting pattern of the disk reservation LED and timer recording LED. White circles are on and black circles are off. For example, even if the disk reservation LED is lit when the disk reservation is on, the presence or absence of reservation information can be determined by looking at the timer recording LED display. Therefore, it is possible to reduce a failure such that the reservation mode is set for any of the recording modes and the recording cannot be performed because there is no reservation information. The above-described LED may be any one that can be visually recognized by the user, and may be a liquid crystal display or the like.
[0037]
The present invention is not limited to the above-described DVD player, and can be applied to a video recording apparatus that performs recording based on reserved recording information of a recording medium by inserting / removing a recording medium on which reserved recording information is recorded.
[0038]
Further, the present invention is not limited to the above-described embodiments, and various other configurations can be taken without departing from the gist of the present invention.
[0039]
【The invention's effect】
According to the present invention, the recording that is held in the reservation information holding unit by the user's instruction via the input operation means without the need to insert / remove the recording medium in which the reservation recording information is set one by one as in the prior art. Since it is possible to switch the reserved recording information of the medium and the apparatus main body, it is possible to improve the usability of the reserved recording work for the user.
