    摘要: For providing a recording/reproducing apparatus, for recoding and reproducing a digital signal onto first and second recording media 200 and 300, in particular, being simple in the controlling method when conducting data copying between those recording media, being difference in the control formats thereof, comprising: a memory 104 for storing therein the digital signal, temporality; an input/output portion 101, through which a control signal and the digital signal for use of recording and reproducing are inputted and outputted; a controller 102 for performing two (2) kinds of controlling, being different from each other, with respect to said first and second recording media, upon basis of a one (1) kind of control signal inputted at said input/output portion; and an arbiter 103 for arbitrating and processing the digital signal in a time-sharing manner among said first recoding medium, said second recording medium and said memory, wherein the signal recorded in the first recording medium 200 recorded onto the second recording medium 300 through the memory 104, thereby making a copy of data between the recording media differing from, but without passing through the input/output portion 101.

    摘要: A recording/reproducing apparatus is provided for effecting digital processing to convert an analog video signal into a digital signal without losing character data superimposed over a vertical blanking period of the analog video signal. The recording/reproducing apparatus for converting the analog video signal into the digital signal and recording/reproducing the converted digital signal has a detector which detects character data, which is superimposed over the vertical blanking period of the received analog video signal, at the recording time. A superimposer which encodes the detected character data and superimposes the encoded character data over a digital signal from which the character data was removed, whereby the digital signal with the superimposed character data is recorded on the recording media. There is also a detector which detects first copy guard data superimposed over the vertical blanking period and second copy guard data superimposed over a color burst signal; and an adder which adds the two detected copy guard data to a signal reproduced from the recording media.

    摘要: A magnetic recording/reproducing apparatus equipped with an image sensor, has a camera portion having an A/D converter for converting a signal from an image sensor into a digital signal and a first digital processor for receiving an output of the A/D converter and for digitally processing thereof. A VTR portion of a helical scan type mounts at least two or more of magnetic heads for recording/reproducing a FM modulated luminance signal and a low band converted chrominance signal. A second digital processor processes a video signal of the VTR. A switching circuit is provided in a preceding stage of the A/D converter. The image sensor signal, an external video signal and a reproduced signal from the magnetic heads are exchanged. The output of the A/D converter is inputed to the second digital processor, and a sampling clock of the A/D converter is exchanged to the most appropriate clock for the respective image sensor signal, the external video signal and the reproduced signal from the magnetic heads.
