Signal Processing for New HQTV Systems
In new television applications, such as interactive videotex, still picture transmission, or where larger, brighter screens are used, improved resolution and flicker-free reproduction are necessary. Picture quality can be improved compatibly by motion-adaptive pre- and post-filtering in combination with picture framestores. This article proposes a new approach for a hierarchical signal-processing scheme where different standards are used for production, transmission, and reproduction. This standard conversion offers inexpensive compatibility through use of simple adapters for different receiver qualities.
