Video signal processing apparatus and method

A video signal processing apparatus, comprising:

• first recording means capable of recording a video signal in conformity with a recording system on a first exchangeable recording medium;
• second recording means capable of recording the video signal on a second exchangeable recording medium in conformity with a recording system different from the recording system of said first recording means;
• and
• control means for recording the video signal on the first recording medium with said second recording means in a case where a residual recording quantity of said second recording medium is smaller than a set value, reading the recorded video signal from the first recording medium by said second recording means in response to a transfer instruction, and recording the read video signal on the second recording medium with said second recording means.

A video signal processing method using a video signal processing apparatus including:

• first image processing means for performing first image processing to a video signal;
• second image processing means for performing second image processing to the video signal, and for generating a signal of a data rate larger than that of the video signal subjected to the first image processing;
• first recording means for recording the video signal subjected to the image processing on a first recording medium capable of being randomly accessed;
• and
• second recording means for recording the video signal subjected to the image processing on a second recording medium capable of being linearly accessed or of being randomly accessed at a speed lower than that of the first recording medium, said method comprising a control step of:
• recording the video signal subjected to the first image processing by said first image processing means on the first recording medium through said first recording means in a first mode;
• recording the video signal subjected to the second image processing by said second image processing means on the second recording medium through said second image processing means in a second mode;
• and
• recording the video signal subjected to the second image processing by said second image processing means on the first recording medium through said first recording means in a case where a residual quantity of the second recording medium is smaller than a set value.

A video signal processing apparatus, comprising:

• a first image processor for performing first image processing to a video signal;
• a second image processor for performing second image processing to the video signal, and for generating a signal of a data rate larger than that of the video signal subjected to the first image processing;
• a first recorder for recording the video signal subjected to the image processing on a first recording medium capable of being randomly accessed;
• a second recorder for recording the video signal subjected to the image processing on a second recording medium capable of being linearly accessed or of being randomly accessed at a speed lower than that of the first recording medium;
• and
• a controller for recording the video signal subjected to the first image processing by said first image processor on the first recording medium through said first recorder in a first mode, recording the video signal subjected to the second image processing by said second image processor on the second recording medium through said second recorder in a second mode, and recording the video signal subjected to the second image processing by said second image processor on the first recording medium through said first recorder in a case where a residual quantity of the second recording medium is smaller than a set value.
