ASIC Solution for 1-channel DVR application using HDD NVP3000 NVP3000 is an ASIC solution to fit for 1-Channel DVR application. It integrates pre/post processor, M-JPEG CODEC, hard-disk controller, and key/jog-shuttle interface. In addition, it supports time-laps recording mode with flexible image compression rate to save disk usage, watermark encoding, and easy interface to most video multiplexer and CIF application. Therefore, it provides cost-effective solution for real-time full duplex video/audio record and play back system. At play back mode, search, fast-forward, rewind, and pause functions are supported. NVP3000 also includes internal buffer to communicate with external CPU for network application, and it supports HDD user accessible area as well as extra pins for key and jog-shuttle interface.
