FLICKER FILTER AND INTERLACER IMPLEMENTED IN A TELEVISION SYSTEM DISPLAYING NETWORK APPLICATION DATA

摘要

A television system (100) with an in-terlaced display screen for displaying net-work application data. A flicker filter (480) is preferably implemented as an infinite im-pulse response (IIR) filter to eliminate sharp transitions in the network application data images. A random access memory (RAM) is used to store the lines of the filtered im-ages and any adjacent lines used for the fil-tering operation. Alternate lines of the fil-tered images are retrieved from the RAM to provide an interlaced image of the filtered network application data images. The inter-laced images are displayed on an interlaced display unit of a television system.
