Title: INFORMATION PROCESSING DEVICE AND METHOD
Abstract:
The present invention relates to an information processing device and method which make it possible to suppress subjective decreases in quality when the bit rate is low. A video metadata generation unit and an audio metadata generation unit generate stream selection support information, which is metadata indicating information about parameters to be maintained with priority, determined in accordance with the contents of the content data. A communication unit transmits the generated metadata and content data of multiple bit rates. This invention may be applied, for example, to a distribution system comprising a file generation device, a distribution server, and a playback terminal.
