Abstract

Recently, the law enforcement community with professional interests in applications of image/video processing technology, has been exposed to scientifically flawed salesmanship assertions regarding the advantages and disadvantages of various hardware image acquisition devices (video digitizing cards). These assertions state a necessity of using SMPTE CCIR-601 standard when digitizing NTSC composite video signals from surveillance videotapes. In particular, it would imply that the pixel-sampling rate of 720*486 is absolutely required to capture all the available video information encoded in the composite video signal. Fortunately, these erroneous statements can be directly analyzed within the strict mathematical context of Shannon's Sampling Theory. Here we apply the classical Shannon-Nyquist results to the process of digitizing composite analog video from videotapes to dispel the theoretically unfounded, wrong assertions.
