With two full days of sessions covering cutting-edge video technologies and techniques, and an exhibit hall featuring the latest gear for pro video, broadcast and AV professionals, Government Video Expo still got down to the basics. Presented by Telestream’s Andrew Haley to a standing-room-only crowd, the session “Intro to Live Streaming Basics” covered terminology, the types of live streams, streaming workflows, where to stream and some techniques and tips.

For those interested in streaming, you first need to determine its purpose and decide on your budget. Basic streaming involves one camera that records and transfers directly to a streaming platform such as Ustream. This is a good solution for streaming to a single location such as an event, a conference or an educational outlet and is the least expensive option. Complex streaming uses multiple cameras, capture cards, switching with graphics and streaming to multiple destinations, such as a church service that is streamed to several locations simultaneously. This is a more expensive solution, but there are variations to fit different budgets.

For the multi-camera solution, Haley discussed the capture of content, and switching and encoding considerations. What features do you need in your program? Do you need media assets? Photos, titles? Picture-in-picture? How much bandwidth do you need?

Haley addressed the different types of connectivity for streaming (wireless Wi-Fi, wired Ethernet, 3G or 4G cellular and bonded cellular); streaming destinations (content delivery network, streaming services or a dedicated server); and how to choose the right delivery method. He suggested that attendees pay attention to lighting, camera positions and audio in order to improve the quality of your streaming.

Haley closed the session with a demo of Telestream’s Wirecast live production software, which enables you to capture your content from a number of input devices, produce your show with live switching, transitions, titles and more, and then stream it live.
