Video: Filter / Buffer products for DTV, Delay Lines, Shift Register Products
Plasma and LCD display technology and HDTV must work with multiple formats ranging from NTSC and PAL TV to HDTV formats. The digital video signal filtering requirements vary for each format to prevent "ghosting" or other unwanted artifact from displaying. NPC video filter buffer products provide a high quality adjustable filter in various configurations to match these multiple formats. NPC video delay line and video shift registers are used to adjust video signal timing to align with other video signals or system clocks.
