Take the guesswork out of the HD test

摘要

As the roll out of HD gains momentum, the question of 'how to make it work' becomes proportionally less relevant than the question of how to test HD to make sure it conforms to established standards. Before we all get too excited, let's remember that HD is nothing to be frightened of. It's just one more video format, and apart from the number of pixels per line and the number of lines per field it has a lot in common with standard definition SDI video. Therefore most of the testing methods that are already tried and tested for the SDI world can be incorporated into new, HD-ready hardware. Videotek, the test and measurement products division of Leitch, used that premise as the basis for development of its new TVM-950HD multi-format high-definition SDI monitor, which is specifically designed to be a versatile, intuitive HD/SD-SDI video and audio measuring and monitoring instrument in a half 19inch-3RU form factor.
