Television systems with enhanced image quality for new broadband channels
Abstract
Methods for improved image transmission via new broadband channels (satellite and cable channels) are developed and demonstrated, with a particular view to future high definition television (HDTV). A digital signal pre- and postprocessing system is designed and realized for a HQ-MAC (high quality-multiplexed analog component) television system, which increases the resolution substantially. The constructed demonstration model shows an impressive quality improvement with respect to standard definition television. Methods for the suppression of jitter are realized. A new high definition progressive production standard is established. A number of improvements in the projector system are realized, with a view to an efficient display for HDTV.
