Hello, I'm going to give a short demonstration of search and index capabilities on webcast videos -- one of the key benefits you get when you use Automatic Sync Technologies' CaptionSync automated captioning.

Captions on webcasts are of course a boon to the deaf and hard of hearing students, but they also benefit the wider community.  For example, it helps English as Second Language (or ESL) students link printed words with pronunciation.  It allows students with different learning styles to pace and review.  And it allows the average student to improve comprehension by taking in material on multiple channels.

Automated captioning essentially delivers a text transcript with synchronization markers to the audio/video. We can now leverage this information to search through the text for our phrase of interest and launch the video player to that exact point of interest!  Let me show you what I'm talking about...

Here we have the captions from one UC Berkeley Computer Science lecture searchable, but imagine the possibilities if the whole course was searchable, or all Computer Science lectures searchable, or everything at UC Berkeley searchable...

Since this is a Computer Science lecture, we'll need to search for something techy.  So let's try "assembly" as in "assembly language".

Now we see all the places in this lecture where the instructor mentioned "assembly".  We see the lecture, where in the lecture, and the text surrounding our search term.  So let's assume that this one down here is the one we're interested in.

Simply click the link... and it launches RealPlayer to that point of interest, downloading the media over the Internet.

Note that this can also be make to work with QuickTime and/or Windows Media Player if preferred.

We can then watch the video from this point.

What student wouldn't benefit from video search?
