Media Content and Enhancement Data Delivery

摘要

A method of outputting media content is described. The media content is coded according to a predefined coding scheme to produce coded media content. Enhancement data, comprising information for selectively enhancing at least one portion of the media content, is also supplied. A corresponding method of providing media content is also described, including receiving enhancement data for selectively enhancing at least one portion of the media content and providing enhanced decoded media content for the at least one portion based on the enhancement data. By providing selective enhancements, e.g. of critical portions, a user experience can be improved without requiring a significant increase in bandwidth and enhancements may be delivered over a different channel to the basic data.
