Abstract
A video signal recording apparatus includes a first device for processing a first time segment of a video signal in response to a second time segment of the video signal. The first time segment relates to a first frame or field while the second time segment relates to a second frame or field which precedes the first frame or field. A second device is operative for interrupting the processing by the first device when the video signal starts to be subjected to an editing process. A third device is operative for recording an editing information signal and an output signal of the first device on a recording medium. The editing information signal represents a time of occurrence of the editing process.
Claims5
An apparatus comprising:
- first means for deleting predetermined time segments of an input video signal, and dividing a remainder of the input video signal into two partial video signals, the predetermined time segments corresponding to predetermined upper and lower lines containing a specified line, wherein a time segment of the input video signal which corresponds to the specified line represents an information signal;
- second means for emphasizing high frequency components of the partial video signals relative to low-frequency components thereof in a direction along a time base;
- third means for emphasizing high-frequency components of output signals of the second means relative to low-frequency components thereof in a vertical direction;
- fourth means for time-base-compressing and time-base-multiplexing output signals of the third means into TCI signals;
- fifth means for extracting the information signal from the input video signal, and converting the extracted information signal into a TCI information signal;
- sixth means for generating a corrective signal designed to compensate transmission characteristics;
- seventh means for combining the TCI signals, the TCI information signal, and the corrective signal into composite signals;
- and
- eighth means for recording the composite signals into a recording medium.
