For sheer data rate, few things can match the volume of continuous throughput like a high resolution video source; a single HD video stream requires an imager sampling rate of ~ 130 MSPS at 16 bits or better, moving 250Mbytes / second. Multiply this problem out for your average retail installation of ~100 cameras, and you’re looking at 25G bytes per second of uncompressed images. Capturing, compressing, transporting, storing and managing that amount of data continuously is a significant challenge for the security and surveillance space. I’ve worked in every aspect of this arena – from imager, sampling, transforms, compression methods, meta data analytics, IP communications, transport layers, to system architecture and storage management. In fact, I was involved in the definition of standards pertaining to the industry, including OSIPS, OnVIF for security and surveillance video, and JPEG/JPEG2000 / MPEG-4 for IEC standards.
Video Cameras
Developed full frame rate IP cameras for the security and surveillance space using Wavelet, JPEG-2000, and H.264/MPEG-4 standards.
Video Encoders
4/8/16 channel video encoders from inception to mass production and delivery
Video switches
Developed a line of scalable video switches that could be interconnected to make crosspoint arrays of thousands of inputs and hundreds of outputs. Later models included video titling overlay on outputs for standalone operation with monitors for low cost.
Video processors
Enhancement, scaling and retiming of video to use in industrial and defense applications. Used large scale FPGAs, frame buffering, and multiple digital inputs and outputs.
