2. Description of the Related Art Conventionally, information devices, such as PCs, having a built-in image encoder, capable of digitizing and capturing image data including moving image data, and reproducing the data have been increasing. It not only inputs the composite signal of the image to the information equipment, but also has a built-in TV tuner,
Some can obtain TV image signals.

There is also a TV receiver which includes a TV tuner and an image encoder separately from the information equipment main body, and transmits digitized signals from an interface (I / F) such as a USB. This TV receiver is connected to a storage device without a TV tuner and an image encoder, takes in image data from the storage device, and reproduces the image data.

Normally, an information device such as a PC only outputs a display signal, and needs to be connected to a display device in order to actually display an image. On the other hand, some display devices have a built-in TV tuner and a function of displaying a TV screen in addition to a function of displaying a display signal from an information device. In this case, the TV screen of the display device can be displayed separately from the operation of the information device.

[0005] Recording an image requires a large-capacity storage device. Since a display device does not usually include a large-capacity storage device, it is generally stored in a hard disk device (hereinafter, referred to as an HDD) on the information device side. In order to record the recording data on the information device side, it is necessary to turn on the power supply of the information device side to be in an operation state.

On the other hand, the recording processing has a function of recording reservation for designating recording at a certain time. In this case, the information device is set in a standby state, a timer is started, and recording is performed at a recording start time. In addition, there is a device that can be started at a designated start time even when the power other than the timer unit is completely turned off instead of the standby state. However, this device is provided with special hardware and is not general.

[0007]

However, considering an information device such as a PC that can be used not only for the recording process but also for e-mail, etc. Until the time when the recorded video starts
It is hard to say that the PC is always in standby. After performing daily tasks other than recording, such as e-mail, completely turn off the power of the information equipment, and set the standby state without turning off the power completely after the scheduled recording time approaches. Could be enough. Also, with the information device turned off,
In many cases, TV is viewed on a display device. In this case, the power of the information device must be changed from off to the standby state before the recording reservation is started. However, if only the TV screen is displayed, the user does not notice this and turns off the power of the information device. It is highly likely that the user will forget to change from the standby state to the standby state.

On the other hand, for example, Japanese Patent Application Laid-Open No. 12-152
Japanese Patent Publication No. 138 proposes a device having a PC with an image capture function that immediately starts recording image data with a quick capture program without starting an OS when a user instructs a capture while the power is off or in a suspended state. are doing.

However, this is achieved only when the capture unit and the information device (note type PC) are integrated, and the power supply and the operation state of both the capture unit and the recording unit can be managed in a unified manner. . In a combination of a display device such as a liquid crystal display and an information device (desktop PC), the display device and the information device have separate power supplies, and the display device generally does not control the power supply of the information device. is there. Therefore, this does not solve the problem of "forgetting the power supply to the standby state immediately before recording".

The present invention solves the above-mentioned conventional problem. It is possible to easily obtain recording setting information such as scheduled recording without operating the information device, and to change the information device to a standby state.
