ABSTRACT:
When a standard TV signal of digital format is a first video signal and another digitized TV signal having a bandwidth wider than that of the first video signal is a second video signal, every two frames of the second video signal are calculated to produce a pixel value sum of the two frames and a pixel value difference between the same and either a resultant interframe calculated output or the first video signal is compressed through two-dimensional orthogonal transformation for ease of storage.
