Digital video pervades daily life. Mobile video, digital TV, and digital cinema are now ubiquitous, and as such, the field of Digital Video Processing (DVP) has experienced tremendous growth. Digital video systems also permeate scientific and engineering disciplines including but not limited to astronomy, communications, surveillance, entertainment, video coding, computer vision, and vision research. As a consequence, educational tools for DVP must cater to a large and diverse base of students. Towards enhancing DVP education we have created a carefully constructed gallery of educational tools that is designed to complement a comprehensive corpus of online lectures by providing examples of DVP on real-world content, along with a user-friendly interface that organizes numerous key DVP topics ranging from analog video, to human visual processing, to modern video codecs, etc. This demonstration gallery is currently being used effectively in the graduate class ``Digital Video'' at the University of Texas at Austin. Students receive enhanced access to concepts through both learning theory from highly visual lectures and watching concrete examples from the gallery, which captures the beauty of the underlying principles of modern video processing. To better understand the educational value of these tools, we conducted a pair of questionaire-based surveys to assess student background, expectations, and outcomes. The survey results support the teaching efficacy of this new didactic video toolset.
