Testing Digital Video Signals
The Digital Era is here to stay, and we are becoming accustomed to the many digital “advantages.” Engineers, however, have seen the darker side of digital video. They have seen incompatibilities between equipment, unexplainable loss of synchronization, “sparkles” in the image, even complete loss of image. Although a lack of proper test equipment and testing knowledge have led some engineers to conclude that digital video has much in common with voodoo and black magic, this paper will show how the same good engineering practices that have produced excellent analog television can also be applied to digital television. Practical, easy to understand test methods and equipment are studied and explained. Real-world examples of problems that have been discovered in digital video installations are discussed, and the test methods that allowed their diagnosis and correction are illustrated.
