Introduction • Caption. Sync is a web-based service provided by Automatic Sync Technologies (AST) for Transcription and/or Closed Captioning of media files. • Caption. Sync was initially funded by the US Dept of Education. • Caption. Sync has almost 2000 users across the country – primarily in Education. • In addition to captioning, AST has expertise in workflow automation, video search and navigation, and the use of synchronized interactive media. © 2010 Automatic Sync Technologies

Agreement Mechanics • Each CSU campus has an “AST Administrator” responsible for overseeing usage of the agreement at their campus. • Any CSU member can get their own Caption. Sync by applying at: http: //www. automaticsync. com/caption/csu_sign_up. php • After AST receives an application, an approval from your campus Administrator is automatically requested. As soon as we receive this, the account is created and you will receive an automated notification. • Every month, the Administrator receives a summary of all usage of the Agreement for your campus. • AST does not directly bill your campus – the CO handles all invoicing from AST and “bills back” all usage to the campuses every 6 months. © 2010 Automatic Sync Technologies 4

New Services • DVD Transfer : send in uncaptioned DVDs or VHS tapes and get back captioned DVDs. • NLE Captions : get back overlay movies to embed caption data in your SD tape. • Result Review : have AST staff review your content to check and repair any errors – useful when your audio is very poor quality. • These services are not covered under the CSU Agreement, but can be accessed from your account and will be direct-billed. © 2010 Automatic Sync Technologies

Workflow Automation • Caption. Sync is very simple to use to upload individual jobs… but what if you have a lot of jobs? • Caption. Sync has an SFTP portal that allows external software to interact with it. • AST provides a simple drag-and-drop app for this purpose. • 3 rd party software vendors can also integrate to this portal, including Lecture Capture systems, Content Management systems, and video editing tools. © 2010 Automatic Sync Technologies

A Quick Tour of Caption. Sync • Settings: update your account; change password; enroll keys. • Help: documentation, downloads, wiki, Support Request. • News: review old news items. • Caption/Transcribe: submit new jobs, check status, redo jobs. © 2010 Automatic Sync Technologies

What happens after you submit? • Caption. Sync ingests your media file and extracts the audio portion. Schedules your job for transcription. • We produce a transcript of the audio portion of the program. Stenographers are trained to use proper captioning conventions. • Divide text into captions, observing guidelines about where to break sentences. System also pays attention to the output formats you requested to conform to constraints on those formats. • Synchronize captions to the video timeline. • Create output files in the format required by your media. Note that format is dictated by the type of player that the content will be played on, not by the media itself. © 2010 Automatic Sync Technologies 14

Deciding What to Caption Many factors to consider: • School/System policy • Time / Urgency • Available budget • Usage frequency • Lifespan of material • Audience (internal or external) • Primary purpose (core vs review vs supplemental) © 2010 Automatic Sync Technologies

Using Speech Recognition • Our work originated from a project funded by Dept of Education to examine how to make captioning more efficient. • Looked at existing techniques, cost structures, and emerging technologies (including speech rec). • Concluded that significant improvements were possible using automation, but we still needed to use human stenographers for transcription task. © 2010 Automatic Sync Technologies 17

Word Error Rate: 0% Everyone loves a booming market, and most booms happen on the back of technological change. The world's venture capitalists, having fed on the computing boom of the 1980 s, the internet boom of the 1990 s and the biotech and nanotech boomlets of the early 2000 s, are now looking around for the next one. They think they have found it: energy. Many past booms have been energy-fed: coal-fired steam power, oil-fired internal-combustion engines, the rise of electricity, even the mass tourism of the jet era. But the past few decades have been quiet on that front. Coal has been cheap. Natural gas has been cheap. The 1970 s aside, oil has been cheap. The one real novelty, nuclear power, went spectacularly off the rails. The pressure to innovate has been minimal. In the space of a couple of years, all that has changed. Oil is no longer cheap; indeed, it has never been more expensive. Moreover, there is growing concern that the supply of oil may soon peak as consumption continues to grow, known supplies run out and new reserves become harder to find. The idea of growing what you put in the tank of your car, rather than sucking it out of a hole in the ground, no longer looks like economic madness. Nor does the idea of throwing away the tank and plugging your car into an electric socket instead. © 2010 Automatic Sync Technologies
