Description

DETAILED DESCRIPTION OF THE INVENTION The field of industrial application + the invention relates to a videotape recorder that can be used for home video recording.

2. Description of the Related Art In recent years, video tape recorders have a function of controlling the power supply of an external receiving device in order to record video and audio signals from the external receiving device.

An example of the conventional video tape recorder mentioned above will be explained below with reference to the drawings.

FIG. 6 shows the structure of a conventional video recorder. In FIG. 5, 1 is a video tape recorder, 2 is an external receiving device, 101 is a setting section, 102 is a clock section, 103 is a clock section, 104 is a timer execution check section,
105 is a built-in receiving device, 106 is a switching section, and 107 is a video/audio recording section.

The operation of the conventional video tape recorder configured as described above will be explained below. When recording video and audio signals of the external receiving device 2 that receives broadcast signals such as satellite broadcasting, first, the external receiving device 2 receives the desired channel (L/) and sets the switching unit 106 to the external input state. What should I do? Further, using the setting section 101, the start time and end time of the desired program are set in the clock section 102. Thereby, the voice signal of the external receiving device 2 can be recorded.

Problems to be Solved by the Invention However, with the above structure, it is not possible to control the channels of the external receiving device from the video tape recorder, so it is not possible to record programs in different time zones on different channels in chronological order. In addition, there was a problem in that programs received by the built-in receiving device and the external receiving device in different time zones could not be recorded in chronological order during an answering session.

Means for Solving the Problems In order to solve the above problems, the videotape recorder of the invention includes a built-in receiving device that receives broadcast signals, a video and audio signal from an external receiving device, and a video and audio signal from the built-in receiving device. a channel setting section that stores channel information of the external receiving device; and an external receiving device control section that issues a control command to the L external receiving device based on a command from the timer execution checking section. According to the above-described structure, the present invention is capable of controlling the receiving channel of an external receiving device from a video tape recorder, and controlling the video and audio signals from the built-in receiving device and the external receiving device using a timer. This can be switched using the execution check section, which allows programs in different time zones on different channels of an external receiving FA device to be recorded in chronological order during answering, and also to be received by the built-in receiving device and the external receiving device. This means that programs from different time zones can be recorded in chronological order during an answering session.

Embodiment A video tape recorder according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the layout of a video tape recorder according to an embodiment of the present invention. Referring to FIG. 1, 108 is an external device channel setting section, 109 is an external receiving device control section, and 3.4 is an external receiving device.

The operation of the video tape recorder constructed as described above will be explained below with reference to FIG. 4.

FIG. 1 shows the configuration of a video tape recorder according to the present invention. When recording a broadcast signal received by an external receiving device during an answering machine, a setting section 101 is used to set a clock section 102 and an external device channel. The reservation contents shown in FIGS. 3 and 4 are set in the section 108. Timer execution check,
The clock unit 104 receives the current time information from the clock unit 103 and the second
As shown in the figure, the starting weight and starting time of the clock section 102 are -5.

Comparing the reservation information of the end time, when the answering machine execution time comes, the timer execution check unit 104 checks the external receiving device number and the external one/- of the external device channel setting unit IQ8 as shown in FIG. Based on the channel information, the external receiving device ult. The control unit 10:9 issues an output command for the external receiver control signal @(~, based on the external receiver 1-7 device code of the external device channel setting unit 108,
The external receiving device control section 109 issues a switching command to the video/audio recording section 106 and a '+ijJ production command to the video/audio recording section 107. It outputs to the external receiving device 1 and the external receiving device 2 shown in the figure to control the external receiving device.

Also, the timer execution check unit 104. When the time to end the recording while at home is reached, an instruction to end the operation is issued to the video/audio recording unit 107, thereby terminating the recording at home.

As described above, according to this embodiment, a channel setting section of an external receiving device and an external receiving device control section that issues a control command to the external receiving device based on a command from a timer execution checking section are provided. By doing so, it is possible to record programs at different times on different channels of an external receiving device in chronological order during answering, or to record programs in different time zones received by the built-in receiving device and external receiving device in chronological order during answering. Can be done.

Effects of the Invention As mentioned above, the present invention is effective in responding to commands from the channel setting section and the timer execution check section of an external receiving device! By providing an external receiving device control unit that issues control commands to the external receiving device (and the external receiving device control section) according to the An excellent effect can be obtained in that the programs received by the receiving device and the external receiving device during the time period can be recorded in chronological order during an answering session.
