BOSTON – Effective video search has been limited, largely because search engines don’t index images. But things are changing with the implementation of Schema, a technology which allows video producers to “wrap” a transcript as an “object” into a video. The Schema initiative is an industry collaboration of Google, Microsoft, Yahoo and Yandex.  It was first introduced to the industry last year.

For an explanation of the impact of Schema, we spoke with Tole Khesin, VP for Marketing at 3Play Media, a Boston-area company that has a voice-to-text technology which is used by media companies, education and enterprise customers.

We interviewed him last week at the Brightcove global customer conference in Boston.
