© 2006 Automatic Sync Technologies 4 About AST AST is a leading provider of synchronization and voice recording search tools to the animation and gaming industries Work on our core technology began in 1990 We have applied our speech processing and pattern identification software to captioning We are partly funded by the Department of Education. Our primary focus is on captioning for education.

© 2006 Automatic Sync Technologies 6 Why Caption? Compliance: web video content is subject to ADA / Section 508 Universal Access: make your content as usable as possible by as many people as possible Improving Comprehension: captioning improves comprehension for all viewers, especially for those with English as a second language Search and Navigation: captioning allows the streaming material to become searchable with traditional text searches Provide Viewers with More Access Options: institutions can improve the quality and range of methods through which viewers can access their products

© 2006 Automatic Sync Technologies 7 Captioning Applications In-Class Video: content used right in the classroom as part of the teaching material Distance Education: course content transmitted as broadcast television, IPTV, videotape, DVD, and/or streaming media Virtual Campus Tours: streaming media video tours of a campus to inform prospective students and parents Remote Conferences/Seminars: conference presentations and seminars are increasingly archived on the web for later viewing

© 2006 Automatic Sync Technologies 8 Captioning Applications Web-based Course Content: supplemental course content or lecture material presented on a course website PR / News Service: streaming media content generated by the public affairs department Special Events: guest lectures, convocations, letters from the president archived on physical media or the web Podcasts: downloadable audio for any of the aforementioned items

© 2006 Automatic Sync Technologies 10 Podcast Captions With M4A and M4B it plays directly in iTunes. and/or With MP3 files it can play in a number of media players with more flexibility in fonts, colors, lines, etc.

AST’s search data makes it possible to perform text- searches on the content. Powerful benefit for entire viewer community; allows viewers to access material of interest without scanning hours of video. Once the text of interest is located, viewers can jump to the precise point on interest in the video.

The key to making the search work is the timed-stamped transcript file which accompanies your video. AST offers this Google Video timed-stamped transcript files at no additional charge with your other captioning results. Or conversely, if you are obtaining funding to add video along with the timed-stamped transcript file to the Google Video archive, why not get it captioned at the same time for no additional cost?

© 2006 Automatic Sync Technologies 18 Video Search Consider the benefit of allowing text searching of all of your video (or audio) content Extremely cost effective -- the search data files are no additional cost when you caption the webcast Very accurate –- clicking the search result gets you to the precise point of interest

© 2006 Automatic Sync Technologies 20 AST’s Goals Speed o Turnaround time for a submission: about 10 minutes Much lower costs than manual captioning Convenience o Simple to use website available when you need it o No special software or tools required o Directly upload your webcast media with no special processing needed

© 2006 Automatic Sync Technologies 21 The AST Captioning Process Service is entirely electronic; submit your program and receive caption results minutes later Input is the program media file (.rm,.wmv,.mov,.m4a,.mp3, etc) and program transcript (.txt), submitted through a web interface Output is caption files for any of the major streaming players (Real, QuickTime, WMV) and iTunes. Flash caption output is coming as soon as Adobe finalizes their caption XML format. Caption files are also for DVDs and legacy videotapes Output also available for video search

© 2006 Automatic Sync Technologies 22 The user submits the media file to AST (electronically) The system o manages the transcription process (if required) o parses the transcript and breaks it into captions o aligns the timing of each caption to the media file itself, o positions each caption according to your instructions, o creates the final caption file for your specific media type. The AST Captioning Process

© 2006 Automatic Sync Technologies 23 Transcription If you already have the transcript, AST can provide formatting guidelines. If you have internal transcription resources, have them transcribe the audio to a simple.txt file. Or you can use AST’s bundled transcription service. Simply submit the media file and our system will automatically manage the transcription process. System can also work with your external transcription vendors; vendors can interact directly with AST system.

© 2006 Automatic Sync Technologies 24 Where is it appropriate? Automated captioning can save you significant time and money, and enable you to caption substantially more content. Automated captioning is suitable for you if: o material is largely narrative with minimal sweetening o program transcripts are available or show can be transcribed o you are captioning archival material (ie: not real time events)

© 2006 Automatic Sync Technologies 33 Feedback on Captioning at San José State University Richard Jackson, SLIS Part-Time Faculty (User with Hearing Impairment) Responsibility of the Educational Media Producer o “I naturally regard captioning as essential for this kind of communication, and if it isn't already required by law for public universities to provide this, I think it should be.” o “If I had had to deal with video without captions when I was in library school (not many years ago), it would have made things unnecessarily difficult.”

© 2006 Automatic Sync Technologies 34 Feedback on Captioning at San José State University Richard Jackson, SLIS Part-Time Faculty (User with Hearing Impairment) Broad value of captioning o “ I don't think one has to be as hearing impaired as I am, or a non-native speaker of English, to benefit from the captions.” o “Many speakers can be somewhat difficult to understand, and the captions help.” o “My wife, who has normal hearing, watches the TV with captions even when I'm not around, because she realized she was able to catch more things being said.”

© 2006 Automatic Sync Technologies 35 Some parting words… Our goal is to make captioning accessible : o Convenient o Simple o Inexpensive o Fast o Flexible While regulations help encourage captioning, compliance can only become universal if captioning itself is made easily accessible
