Abstract

Exchanging multimedia data between a multimedia device and a network involves digitally coupling a communications device to the multimedia device. A profile of the communications device is stored on a data store accessible via the network. The profile describes multimedia capabilities of the communications device, the profile adapted to include a description of multimedia capabilities of the multimedia device. The profile is accessed for purposes of formatting the multimedia data via a network entity. The multimedia data is formatted via the network entity based on the profile to be compatible with the multimedia device. The multimedia data is exchanged between the multimedia device and the network via the communications device.
