Apparatus and method for upgrading codec

摘要

An apparatus, system, and method for upgrading to a new codec used in a digital broadcasting environment are provided. The apparatus includes a first transceiver (410) that receives a transport stream; a first parser (420) that parses the transport stream to determine a codec packet, and decodes codec information contained therein; and a codec-comparison unit (430) that compares the decoded codec information with existing codec information, and determines whether a codec should be downloaded. The system includes a device manufacturer (200) that manufactures a codec packet; a broadcaster (100) that transmits a transport stream containing the codec packet; and a rendering device (400) that parses the transport stream, compares existing codec information with new codec information, and upgrades a codec based on the comparison. The method includes receiving a transport stream; parsing the stream; decoding new codec information; comparing the new codec information with existing information; and upgrading the codec based on the new codec information.
