I found this great video from Intercall that reviews and demonstrates the all of the amazing features and performance of the Epiphan Pearl. It really is a fantastic solution for capturing and live streaming events, lectures, education, worship, corporate, and so many other situations. It allows you to integrate powerpoints, graphics, video, and slides along with video from multiple sources including SDI, HDMI & DVI. It comes with 1TB of storage that can hold about 250 hours of content. It's simple and easy to encode into multiple formats and send multiple streams to up to 3 different destinations / CDNs. You can also use it to feed digital signage.
