Video Noise-Reduction FIFOs
Oki has industry-leading technology for reducing noise caused by weak signal or radio interference (beat frequency noise) when video is carried via Radio Frequency (RF). The filtering is done in the digital domain utilizing an internal DRAM-based FIFO so no external memory is needed - allowing a single chip solution.
