- 34. Open Content • Initiatives (iTunesU, public portals, MIT OpenCourse) • Schools of Medicine • Publicly available to all • Limited to only students enrolled? the wider campus?
- 35. Intellectual Property • Huge faculty concern • Institutional policy around IP • Different from copyright of presentation • Story - Course syllabi – When a faculty member leaves the IP goes with them but the copyrighted syllabus remains the with the University
- 36. Copyright of Captured Lecture • Usually University owns the copyright if its resources are used • Watermarking, bumpers, drm, other? • Story: – Student brings camera to talk and asks permission to tape. Uses their own equipment, who owns it?
- 37. Permissions and Releases • Permission/Release forms – Your own? Creative Commons? – Revokable – Repurpose – Educational use/non-profit • Who is responsible? (Office of Education? Courses? Departments? IT?) – How long do you keep materials (digital, original? record only?)
- 38. Appropriate Use and Reuse • Applies to more than just audio/video • To share or not share • Balance student needs with faculty concerns and institutional rights • Case study – A “copyrighted” video shows up on Youtube and is reported by a faculty member. What do you do?
- 39. Course Content Access & Appropriate • Cover all course materials (electronic and hard copy) • Provide students with more flexibility to access course materials • Clarify policy on student sharing of course materials • Address faculty concerns regarding redistribution of content • Provide mechanism for addressing policy violations

Editor's Notes

- #4: First we are going to tell you a story. Our story. Our story of a building and a desire to re-architect our video capture solution. Then talk about what we learned and the broader issues facing institutions who are interested in pursuing lecture capture in an enterprise way\n

- #14: The facility consists of 120 gsf spread across 5 stories and includes 20 traditional classrooms,like we are sitting in today and include flexible seating, wired and wireless connectivity, HD projection and capture in every room. 3 unique capture systems. 10 miles of fiber optics and over 100 miles of CAT 6A 10Gb/s \n
- #15: \n
- #16: External drivers are those factors outside of the SoM and outside of its control, yet which have a profound effect on how we architected this system\n
- #17: In the past storage has limited our abilities to digitally record and repurpose all of our content, that barrier no longer exists. In our first year of operation we expect to capture 500TB of data (not keep it all, just capture it). As an example of change, when I began the design of this system we had planned 32TB and that doubled to 64TB when we procured the storage and within the last few weeks we have been notified that if we had purchased today we could have doubled our capacity to 128TB for less money. \n
- #18: Another hurdle that has been cleared is the processing power of servers or purpose built encoding hardware. Each of the classes we capture has a minimum of two streams of HD 1080i video that are captured as separate streams and weigh in at 250MB per file. Just a few years ago we would have never considered it feasible to encode many HD streams and deliver them by the end of the day. When the facility opens we will be able to deliver an .mp3 file to Sakai before the lecturer even exits the classroom and have 4 different versions of the lectures online in under 3 hours and this will only get better. Before the years end we expect Apple to release 12 core servers which could reduce the amount of hardware needed and in turn save on power consumption\n
- #19: As many of you know the race to make devices smaller, faster, and cheaper is accelerating at an unbelievable pace. With this device I can record audio in stereo, record, edit and post video as well as stream live to the internet...oh and by the way, it’s a phone. Instead of ignoring these pressures we have embraced them and have made an effort to capture our media at higher qualities and deliver our content in a multitude of flavors that will all play on mobile devices. In fact we changed our entire system to downloadable files and rewrote our acceptable use policies because of the pressure. We are also moving forward with a pilot where we distribute FlipHD cams to our students so that they can record, share with their faculty and peers. In Phase II of our capture systems project we will create an interface for these students to upload and share more easily. Embrace change because your students already are....\n

- #21: All roads lead to mobility\n66% of students report listening to podcast monthly\n23% of students report watching lectures on portable media up from 5% in 2008\nExpect these numbers to grow as newer video devices are made available\nbeing asked to deliver podcasts in more digestable manner\n
- #22: \n
- #23: With the advances made in storage, processing and mobile video capture the number of distribution channels has skyrocketed. Again two external factors that are pushing us to rethink the lifecycle of our media comes external factors. We now need to not only produce media for internal portals and learning management systems, we now must account for public facing distribution channels such as Youtube and iTunesU. \n
- #24: As you might imagine, Youtube is a driving force behind this movement to produce and upload video. The most recent statistics are staggering:\nMore than 100,000,000 unique visitors per month20 hours of video uploaded every minute\n1,200,000,000 downloads per day\n\n
- #25: \n
- #26: This has been a great surprise and we are happy to be actively engaged in the open source movements that are on the leading edge of lecture capture. The most compelling inter University project out there is the Opencast project out of UC Berkeley which will release their 1.0 product towards the end of the year. When our system goes live in August 2010 we will immediately begin work on integrating key components of their systems into our product. This is something I will speak further about in a later slide. \n
