Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for making a recording reservation of a recording / reproducing apparatus such as a video tape recorder (hereinafter, referred to as VTR).

[0002]

2. Description of the Related Art In recent years, VTRs and other recording / reproducing apparatuses equipped with a digital interface have been increasing. In the digital interface, not only moving picture signals and audio signals but also control signals can be transmitted. This makes it possible to perform power supply control, channel selection operation, and the like from another device connected via the digital interface. By utilizing these, it is possible to perform reservation recording using signals of an external device such as a receiving device connected by a digital interface.

[0003] A conventional reservation recording method will be described below.

A recording reservation set by a remote controller or the like controls channel selection, recording start, and end based on a clock mounted on its own device. The same applies to a reservation using a signal from an external device such as a receiving device connected via a digital interface. When the start time comes, power is supplied to the external device via the digital interface, and channel selection of a reserved channel is started. A request is made, and only when these are correctly received, the reservation recording is actually started. Also, when the reservation is completed, the device that has set the reservation
When a termination request such as OFF is made, the reservation recording is terminated. At the end of the reservation recording, the reservation is treated as completed and if the set reservation has been repeatedly specified, such as "execute every day" or "execute every Monday", the next A reservation change request to the execution date and time is made. If the repetition is not specified, a reservation change request is made. If the repetition is not specified, a reservation deletion request is made.

[0005] In addition, reservation recording can be performed from an external device up to execution control such as setting, starting and ending reservation recording. For this reason, a reservation in which the reservation record by the own device and the reservation record by the external device are mixed is set, and it is necessary to manage them and perform execution control.

A conventional reservation recording method will be described below.

The recording reservation specified by the own device controls the start and end of recording based on a clock mounted on the own device. Also, in executing the reservation, the program is cut off from the designated time by 20 to 3 to prevent a loss of time until the mechanical system actually starts operating or a slight clock shift to prevent the program from being cut off.
It is common to start execution 0 seconds earlier.
In addition, the recording start and end of the reservation recording designated by the external device are controlled by the external device based on a clock mounted on the external device. However, if the device to be controlled from the external device has already executed some kind of reservation, control from the external device is not accepted in order to give priority to the reservation being executed. In addition, during the execution of the reservation from the external device, if the execution of the internal reservation of the own device is set in duplicate, wait for the end of the execution of the reservation from the external device,
Internal reservation execution is started. As described above, when the reservations are set repeatedly, the reservation whose execution has been started first has priority.

[0008]

However, in the above-mentioned conventional method, when the external device is not connected or connected but not operating normally, the power is turned on,
Even if a start request such as channel selection is made, the request may not be accepted correctly. Of course, in that case, the recording cannot be started, and if only the start request is issued at the timing of the start time, the reservation is not executed thereafter unless the start request is correctly received. Had. When the reservation execution is terminated, if the termination request, the reservation change request, or the reservation deletion request is not accepted due to the external device not being connected or being connected but not operating normally, the power is turned on. As a result, it was left unattended and the reservation was not changed or deleted. An object of the present invention is to solve the conventional problem described above and to prevent a situation in which reservation recording is not started at all when an external device does not accept a start request due to some problem.
Also, if the external device does not accept the termination request, reservation change request or reservation deletion request due to some problem,
An object of the present invention is to prevent a situation in which a power supply is left on.

Further, in the above-described conventional configuration, while the reservation recording of the own device is being executed, a request to start execution of the reservation recording from the external device cannot be received. In the case of a continuous recording reservation in which the end time and the start time of the reservation of the external device coincide with each other, the subsequent external device issues an execution start request at a time earlier than the actually specified start time. At this point, since the own device is still executing the reservation, the start request from the external device is rejected, and the reservation cannot be executed unless the start request is made again from the external device. Had.

The present invention solves the above-mentioned conventional problem. When performing continuous recording reservation in which the end time of the reservation of the own device matches the start time of the reservation of the external device, the reservation execution of the own device is performed. Is completed earlier than the actual end time and is kept in a standby state, so that both reservation records can be executed faithfully in accordance with the user's settings without rejecting a start request from an external device, thereby satisfying the user's wishes. It is an object of the present invention to provide a reservation recording method capable of performing a reservation recording.
