Abstract
Content-based analysis is performed on multimedia content prior to encoding the multimedia content in the rendering chain of processing. A content-based index stream is generated based on the content-based analysis and the content-based index stream is embedded in the multimedia file during rendering. The content-based index stream can be used to generate a content-based searchable index when necessary.
