Abstract

An information recording apparatus and an information recording method are capable of recording video or other signal being seen on a television receiver by a simple operation, and are also capable of preventing user'"'"'s operation errors. The information recording apparatus comprises a second input and output unit connected to a first input and output unit, an analog input terminal connected to an analog output terminal, an information acquiring unit for acquiring the selection state of a first selector by transmitting a command to an information output unit, and a recorder for recording by selecting the output of the second input and output unit or analog input terminal, same as the selection state, by a second selector.

Claims

1. An information recording apparatus for recording at least either digital broadcast signal or analog broadcast signal, as being connected to a television receiver including a first selector for selecting either digital broadcast signal or analog broadcast signal, and sending to a monitor, an information output unit detecting which signal is selected by the first selector, a first input and output unit for issuing the detection result of the information output unit and digital broadcast signal, and an analog output terminal for issuing analog broadcast signal, comprising:

a second input and output unit connected to the first input and output unit;

an analog input terminal connected to the analog output terminal;

an information acquiring unit for acquiring the result of detection by the information output unit;

a second selector for selecting either digital broadcast signal or analog broadcast signal;

a recorder for recording the signal selected by said second selector in either digital system or analog system; and

a controller for

controlling the second selector to select the digital broadcast signal and record in the recorder in digital system when the detection result of the information output unit acquired by the information acquiring unit is the information showing selection of digital broadcast signal, or

controlling the second selector to select the analog broadcast signal and record in the recorder in analog system when the detection result of the information output unit acquired by the information acquiring unit is the information showing selection of analog broadcast signal.

2. The information recording apparatus of claim 1, further comprising:

an encoder for converting the analog broadcast signal entered through the analog input terminal into a digital signal,

wherein the second selector selects either the digital broadcast signal or digital signal; and

wherein the controller

controls the second selector to select the digital broadcast signal and record in the recorder in digital system when the detection result of the information output unit acquired by the information acquiring unit is the information showing selection of digital broadcast signal, or

controls the second selector to select the digital signal and record in the recorder in digital system when the detection result of the information output unit acquired by the information acquiring unit is the information showing selection of analog broadcast signal.

6. The information recording apparatus of claim 2, wherein the second input and output unit and information acquiring unit compose the interface specified in IEEE1394 standard.

3. The information recording apparatus of claim wherein the second input and output unit and information acquiring unit compose the interface specified in IEEE1394 standard.

4. An information recording method for recording at least either digital broadcast signal or analog broadcast signal, as being connected to a television receiver including a first selector for selecting either digital broadcast signal or analog broadcast signal, and sending to a monitor, an information output unit detecting which signal is selected by the first selector, a first input and output unit for issuing the detection result of the information output unit and digital broadcast signal, and an analog output terminal for issuing analog broadcast signal, comprising:

a step of connecting to the first input and output unit;

a step of connecting to the analog output terminal;

a step of acquiring the result of detection by the information output unit;

a step of selecting either digital broadcast signal or analog broadcast signal;

a step of for recording the signal selected at the selecting step in either digital system or analog system; and

a step of controlling for

controlling the selecting step to select the digital broadcast signal and record at the recording step in digital system when the detection result of the information output unit acquired at the detection result acquiring step is the information showing selection of the digital broadcast signal, or

controlling the selecting step to select the analog broadcast signal and record at the recording step in analog system when the detection result of the information output unit acquired at the detection result acquiring step is the information showing selection of the analog broadcast signal.

5. The information recording method of claim 4, further comprising:

a step of converting the analog broadcast signal entered through the analog output terminal into a digital signal,

wherein the selecting step selects either the digital broadcast signal or the digital signal; and

wherein the controlling step

controls the selecting step to select the digital broadcast signal and record in the recorder in digital system when the detection result of the information output unit acquired at the step of acquiring the detection result is the information showing selection of the digital broadcast signal, or

controls the selecting step to select the digital signal and record in the recorder in digital system when the detection result of the information output unit acquired at the step of acquiring the detection result is the information showing selection of the analog broadcast signal.
