Pictron Media Gateway

The addition of video clips to a web site makes it more compelling to visitors. In the past, cataloging information within video content hasn’t been as easy as it has been with text-based pages. Pictron has now changed this with their Media Gateway, which can search and index video content. This technology works with stored clips as well as real-time streaming.
By using intelligent video analysis techniques, The Pictron Media Gateway performs the following steps:
Scene changes are detected and key frames are created in a storyboard
Features present in the key frames such as color, texture, human faces and shapes are recognized and recorded in a database. SMPTE time code is used for reference.
Text overlay information present is also recorded.
Verbal speech present in the audio track is transcribed using speaker independent speech recognition. If “closed caption” is present, that text can be used for the transcript. Music, silence and specific speakers can also be detected.
Videos can be searched using visual cues, text content or other database information using any standard browser. Now it is quite easy for anyone to retrieve a specific video clip, with just the click of a mouse button.
