摘要： Apparatus and methods of using content information for encoding multimedia data are described. A method of processing multimedia data includes receiving multimedia data, and encoding the multimedia data into a first data group and a second data group based on content of the multimedia data, the first data group being configured to be independently decodable from the second data group, and wherein the first and second data groups are encoded at different quality levels. The method can also include classifying the content of the multimedia data and encoding the multimedia data based on the content classification.
