Abstract
The present invention provides an extensible disc player that is upgradeable to play new content types. The player's capability can be extended by downloading an appropriate decoder from a web server via the Internet. In this way, the player can play back contents that it does not originally support. If the content type is unknown, the player will check whether the disc contains a URL for linking to a web site containing an appropriate decoder. If the disc contains the URL, the player will access the web site to download the appropriate decoder. In a similar manner, the capability of a recorder can also be expanded by downloading appropriate encoders from the Internet.
