Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
82 words
A video printer for visually recording a video signal on a recording medium, comprising: sampling means for sampling the video signal for one field or one frame over a plural number of fields or field periods; and modulating means for modulating said video signal according to the sampled signal by said sampling means or signals synchronized with the sampled signal, the video signal modulated by said modulating means being delivered to a monitor so as to be displayed on the monitor screen.
Claim 2
Dependent Claim
82 words
A video printer for visually recording a video signal on a recording medium, comprising: sampling means for sampling the video signal for one field or one frame over a plural number of fields or field periods; and modulating means for modulating said video signal according to the sampled signal by said sampling means or signals synchronized with the sampled signal, the video signal modulated by said modulating means being delivered to a monitor so as to be displayed on the monitor screen.
