Apparatus and method for storing and reproducing high-resolution video images

Apparatus for reproducing a monochrome video signal from a record medium, said monochrome video signal having first and second signal components stored in separate respective areas of said record medium, each of said first and second signal components representing a different complete lower resolution version of said monochrome video signal, each of said areas of said record medium storing a single frame of video signal, said apparatus comprising:

• means for reproducing said first and second signal components of said monochrome video signal from said separate areas of said record medium;
• means for supplying a clock signal having pulses at a predetermined clock frequency and for supplying a complement of said clock signal;
• and
• means for combining said reproduced first signal component with said reproduced second signal in accordance with said clock signal and said complement clock signal, respectively, to produce said monochrome video signal, each of a plurality of samples of said first signal component being offset from a corresponding one of a plurality of samples of said second signal component by one half of the duration of one pulse of said clock signal.

Method of storing a high-resolution monochrome video signal on a record medium, comprising the steps of:

• receiving a monochrome video signal;
• supplying a clock signal having pulses at a predetermined clock frequency and supplying a complement of said clock signal;
• sampling said monochrome video signal at each pulse of said clock signal to produce a first sampled video signal comprising a first, complete lower resolution version of said monochrome video signal;
• sampling said monochrome video signal at each pulse of said complement clock signal to produce a second sampled video signal comprising a second, complete lower resolution version of said monochrome video signal, each sample thereof being offset from a corresponding sample of said first, complete lower resolution version by one half of the duration of one pulse of said clock signal;
• and
• recording said first and second sampled video signals in respective different areas of said record medium.
