Experiments with a slope-feedback variable-velocity-scanning method for compressing the bandwidth of television signals are described. The test conditions were intended to demonstrate the method under favourable conditions and one test-pattern of moderate complexity-test-card 'C'-only was used. The experiments showed that smoothing of the signal by narrow bandwidth can be overcome using the method. But, even at best (corresponding to the least compression ratio observed = 1.7/1), spatial distortion of the received picture is noticeable.
