Video: Lecture Capture and Streaming Workflows in Higher Education

In this excerpt from a 流媒体 West 2016 panel, Duke University Senior Media Engineer Todd Stabley explains 4 workflows currently used at Duke for various operations, including an expanding live sports video program and a central lecture capture initiative that encompasses more than 120 classrooms with recordings of 100 classes per day.

托德Stabley: We've got, I would say, four workflows that I just wanted to highlight. The first is we have a pretty large central lecture capture initiative at Duke. 我们从2005年就开始这么做了. That's a big piece of how we do streaming. 这是通过电器实现的. They're installed in about 120 classrooms. 我们做了大量的录音, upwards of maybe a hundred classes a day during the peak of the semester. 这是一大块. The goal of that one is pure automation. The instructors need to be able to walk into a room, basically they could plug in and have what they're showing on the projector and a video of them captured automatically and end-to-end it's just seamless for them.

The second workflow is more of a self-service approach where they're using software, 相机, and iOS devices to create video and need a place to publish it. For that, primarily we use a tool called WarpWire which is a replacement for us. 我们之前使用过创作. We were looking for something that had what we call asset-level security where 创作 didn't have that. We wanted to be able to take these videos and have this be more of a publishing engine then a destination where you'd log into a single portal and have your stuff there. We wanted to be able to put all of these videos in various systems so they can see under the display section there and have it preserve the integration with our identity management system.

We worked with this local company, and basically built this from the ground up. It's been running for about two years now. They've got interest in all sorts of other schools. 我想斯坦福和耶鲁都在用. It's getting pretty popular and we're real excited with how that's going. That's kind of how we handled the on-demand publishing piece.

We have live streaming and various ways that we do that. Panopto is our lecture capture provider. 有些课程是这样的. We use Wowza Streaming Server or Media Engine now. It's hard keeping up with your terms Chris. That handles basically the catch all for various events. I wanted to mention, we do a lot of IP camera streams from our Wowza server. It seems to be a really big niche for us.

Duke Athletics did a big renovation recently of our Wallace Wade football stadium. It had seven 相机 going for the duration of that. We streamed over a petabyte of data, mostly through that. We also have a presence on the coast for the Marine Lab and they have two 相机. We're seeing a lot of interest in IP camera streaming with a lot of it.

第四个我没有写在这里, but it's kind of like a bespoke media production and streaming service. We do a lot with MOOC's now at Duke, massively open online courses. Online learning is just becoming bigger and bigger. In the past we had had faculty help them create their own videos for these, but the production values weren't great so we've switched to having a professional team of people actually produce this video for them. That's kind of a newer initiative for us.
