Content consumers expect webcasts to appear produced and professional, with multiple camera angles, graphics, and all of the elements we've traditionally associated with television broadcasts. This hasn't happened as quickly as it might, in part because of the cost of dedicated video networks and the limitations of SDI or HDMI connections.
Many of these obstacles are quickly falling away as a result of NewTek's royalty free NDI (Network Device Interface) technology, which allows for SDI and HDMI camera outputs to be connected to a standard GigE network. This significantly reduces network and bandwidth requirements for multicam webcasts, eliminates the distance restrictions of HDMI cabling and permits 4K video streaming without the cumbersome limitations of using four SDI cables.
By using NDI in a video-over-IP network, content creators can also use the same Ethernet connection to control remote cameras, such as the PTZ (pan, tilt, zoom) units that have become very popular for live webcasts that don't have the budget or crew that would be necessary for a traditional style multi-camera production. Customers adapting quickly to all-live production spaces—including those from sports, schools, government, houses of worship, and corporations – are making the most of the combination of NDI and the high-quality imaging recorded by the latest generation of PTZ cameras....[continue reading]
