First Claim
Patent Images
1. A method for processing a multimedia bitstream comprising:
- providing a multimedia bitstream having multimedia content representing a multimedia signal;
analyzing the multimedia bitstream for characteristics of the multimedia signal useful for determining a scene change;
determining scene change information based on the characteristics of the multimedia signal useful for determining the scene change;
embedding the scene change information into the multimedia bitstream to produce a hybrid multimedia data stream;
extracting the scene change information from the multimedia bitstream; and
manipulating the multimedia bitstream based on the extracted scene change information.

Abstract
Systems and methods for embedding scene change information in a multimedia bitstream to form a hybrid multimedia bitstream having data representing scene change information as well data representing a multimedia signal. The embedded scene change information may be extracted from the multimedia bitstream by an executable module to assist in manipulating the multimedia bitstream in subsequent steps.
