Lecture capture in higher education: a Northwestern study?

How is higher education handling lecture capture in 2009?  A Northwestern University study polled academics from multiple institutions and nations, then shared the results (pdf).

Some highlights from their findings:

Although the data indicates implementation is widespread, few have done so beyond a small number of classrooms.

There appears to be a lack of standardization; no single method has shown itself to be more
prevalent than another. There are no firmly established best practices for lecture content collection, manipulation, or delivery.

The central IT organization appears to be the group most often leading the implementation and management of these services, although almost a third of the respondents indicate lecture capture is initiated and managed by individual schools, departments, and in some cases, individual faculty.

Almost half of the institutions surveyed share content via their course management system. Just over half make a portion of their captured content publicly available.

Just over half the respondents record video as part of the captured content. The other half focus on audio only, or audio and content.

Only a quarter of the respondents have an automated system for lecture capture recording. Most systems require some level of hands-on support.
