Abstract

A media exchange description language (MX-DL) is disclosed. The media exchange description language (MX-DL) may be used to facilitate media exchange within a media exchange network, such as a home network. Methods of determining an operability of a media item within a media exchange network are also disclosed. The methods may utilize the media exchange description language (MX-DL) to convert a media format of the media item into a compatible media format usable within a media exchange network. Devices and device components for performing the disclosed methods are also disclosed.
