When dealing with high definition visual communication products, developers will tend to focus on selecting the right hardware and optimizing the codecs and media paths that can handle the high CPU load that HD entails. Savvy developers will take steps to manage the large number of additional tasks that make an HD visual communication product. In this webinar, Tsahi Levent-Levi & Sagee Ben-Zedeff will outline and explain the hidden challenges and additional tasks that developers need to take care of when dealing with HD: * The struggles of interoperability * System management and configuration * Dealing with the visual communication ecosystem * Handling system integrators
