Because of their high picture quality and low cost, S-VHS videocassette recorders (VCRs) have become popular in the growing professional video community. This article considers several technological improvements for higher picture quality, the main design goal of a new portable VCR. These include advanced metal heads and cylinder-mounted preamplifiers to improve carrier-to-noise ratio and a digital signal processor, including a time base corrector and a chrominance noise reducer, to improve the clarity of the reproduced picture.
