Multi-Channel Video Decoders Feature Auto Contrast Control And Noise Filtering

Three multi-channel NTSC/PAL video decoders deliver superior picture quality. The devices feature 2D adaptive comb filter core and image enhancement techniques, such as auto contrast and video noise filtering. With the ability to simultaneously decode four channels of video input, the TVP5158, TVP5157, and TVP5156 are ideal for video surveillance and video conferencing designs that require multiple-channels of decoding in a cost- and space-efficient manner. Also, flexible video outputs on the TVP5158 and seamless interface to the company’s digital media processors based on DaVinci technology reduce system cost by up to $10 by eliminating the need for an external FPGA. The three video decoders are available for sampling. Pricing for the TVP5158 is $8.25, $7.75 for the TVP5157, and $7.25 for the TVP5156 in 1000-piece lots. An evaluation module will be available in the fourth quarter. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
