    22. 22. The Internet
    23. 23. What’s Next?
    24. 24. The Scenario
    25. 25. What We Know <ul><li>The client wants to go online with their courses. </li></ul><ul><li>The courses are composed of ppts, images, videos, documents, and audio (for our purposes: legacy materials).  </li></ul>
    26. 26. What We Don’t Know <ul><li>These courses may also use older materials, such as video tapes, floppies, microfiche, and photocopies. </li></ul><ul><li>These materials may already be virtual, but we can assume from the nature of the question that a portion are physical. We don't really know. </li></ul><ul><li>They may be synchronous or asynchronous courses and materials, but we don't know. </li></ul>
    27. 27. The Approach <ul><li>The groups doing the most work on conversion from legacy materials to digital materials and their deployment are museums, libraries and universities, and public sector organizations. </li></ul><ul><li>These organizations have already stumbled on benchmarks and constraints (i.e. the size of video files, cost of conversion, cost of storage, etc.) and navigated around problems. </li></ul><ul><li>The move from physical training materials to digital materials is analogous to moving classes online. </li></ul>
    28. 28. Analyzing Needs <ul><li>How do you decide what to digitize and what not to? </li></ul>
    29. 29. It Depends… <ul><li>Depends on your mission and your organization </li></ul><ul><li>Depends on the media </li></ul><ul><li>Depends on your users </li></ul><ul><li>Begin with the End in Mind </li></ul>
    30. 30. Principles to consider <ul><li>Cost </li></ul><ul><li>Use </li></ul><ul><li>Condition of original </li></ul><ul><li>Rescanning in future? </li></ul><ul><li>Type of organization </li></ul><ul><li>Begin with the End in Mind </li></ul><ul><li>Customize and Tailor </li></ul>
    31. 31. Different Materials Different Problems <ul><li>Paper documents are the least complex due to standardized nature and use of content </li></ul><ul><li>Audio is complex due to changing formats. Reformatting may occur less often than video but more often than text </li></ul><ul><li>Video and film are the most complex due to both visual and audio elements, reformatting may be needed often </li></ul>
    32. 32. Cost of Digitization <ul><li>Technology is becoming less expensive </li></ul><ul><li>Cost of storing digital materials </li></ul><ul><li>Cost of storing analog materials </li></ul><ul><li>Labor (human hours) </li></ul>
    33. 33. Digitizing for Employee Performance <ul><li>Broader access to materials allows employees to perform job tasks more efficiently </li></ul><ul><li>Centralized repository allows access from any location </li></ul><ul><li>Allows employee access regardless of frequency of content use </li></ul><ul><li>Ensures accuracy of performance due to access to documentation </li></ul>
    34. 34. Four Ways to Digitize <ul><li>To optimize resource allocation, digitize to fit your client’s needs: </li></ul><ul><ul><ul><ul><li>Preservation </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Use </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Access </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Commerce </li></ul></ul></ul></ul>
    35. 35. Digitization for Preservation <ul><ul><ul><li>Use lossless formats (such as JPG 2000, MPEG 2 “I” frame only) </li></ul></ul></ul><ul><ul><ul><li>Standardized formats across industries </li></ul></ul></ul><ul><ul><ul><li>Files tend to be very large and expensive to store and transport </li></ul></ul></ul><ul><ul><ul><li>Highest Cost in human hours </li></ul></ul></ul><ul><ul><ul><li>Video sizes: 30-90 GB per hour </li></ul></ul></ul><ul><ul><ul><li>Highest technology requirements for recipients </li></ul></ul></ul>
    36. 36. Digitization for Use <ul><ul><ul><li>High quality, but efficiently compressed </li></ul></ul></ul><ul><ul><ul><li>Examples include standard MPEG 2 (DVD format) video, and possibly Quicktime and WMV at higher quality </li></ul></ul></ul><ul><ul><ul><li>Files are large, but not as large as preservation files </li></ul></ul></ul><ul><ul><ul><li>Possible to transfer over internet or LAN </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 2-8 GB per hour </li></ul></ul></ul>
    37. 37. Digitization for Access <ul><ul><ul><li>Small file size, but typically lower resolution </li></ul></ul></ul><ul><ul><ul><li>Able to be streamed over internet or LAN </li></ul></ul></ul><ul><ul><ul><li>Cross-platform formats, including WMV, QT and RM </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 150-400 MB per hour </li></ul></ul></ul>
    38. 38. Digitization for Commerce <ul><ul><ul><li>Very small file sizes, but low quality </li></ul></ul></ul><ul><ul><ul><li>Used as advertising on websites, digital book previews (i.e. Amazon.com), or small scale music samples </li></ul></ul></ul><ul><ul><ul><li>Cross-platform, lossy, formats including Flash, PDF, and mp3. </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 20-80 MB per hour </li></ul></ul></ul>
    39. 39. To Consider <ul><li>Cost </li></ul><ul><li>Use </li></ul><ul><li>Condition of original </li></ul><ul><li>Migrating in future? </li></ul><ul><li>Type of organization </li></ul><ul><li>Begin with the End in Mind </li></ul><ul><li>Customize and Tailor </li></ul>
