Abstract: This talk is a brief summary of a journey in video conferencing industry. It starts with some background information about video compression. Then it briefly goes through the video conferencing product development on software, DSP and hardware and show some key algorithms for each platform. In this talk, we will try to explain: why the video encoder is so complex? Where does the complexity come from? Once the codec complexity is appreciated, it becomes natural to ask help from DSP or hardware accelerator for real-time application, like video conferencing. Next, we share some product developing experience from video conferencing industry (mainly Poly). We show our perception of how things evolve over the time in video conferencing market. In Poly, we have evolved from software-based solution, to DSP-based solution, now to hardware-based solution. Optimization has been one of the most important areas in the product development cycle. Specific algorithms have been developed for each platform. In final part, we show some new features in video conferencing products (h265, machine learning), touch on future trend, and give a summary of the talk.
