Enhanced Television — A Progressive Experience

L. John, E. Baldwin

Before adopting an incompatible higher definition television standard, which could not be broadcast in an acceptable bandwidth without the use of several field stores in every receiver, it is sensible to investigate the use of field stores in receivers to provide noticeably better subjective vertical resolution by progressively scanning the display. The transmission would continue to use conventional interlaced 525 or 625-line standards. If aliasing due to the sampling inherent in the number of lines in a displayed field is the important limitation, the use of progressive scanning in the display could double the vertical resolution. This article reports the progress of such an investigation at the Independent Broadcasting Authority.
