Latest Patents

Chang’s listed patent, “Systems and Methods for Differential Media Distribution,” describes a way to transmit changes between versions of a media file rather than requiring the entire updated file to be sent. A differential versioning server compares two media files, creates a differential data file from their differences, and produces metadata that helps a decoder reconstruct the newer file from the earlier one. A receiver and decoder can then apply the differential data to the original file to generate the updated media.

Career Highlights

The described invention addresses electronic media distribution through differential versioning. By encoding changes and providing information needed to apply them, the system is designed to support reconstruction of updated media files at the receiving end.

Collaborations
