Abstract

A system and method supporting the automatic conversion of multimedia information from a first format to a second format in a broadband access gateway and/or network-based server are disclosed. The broadband access gateway and/or network-based server may convert multimedia information that is in a format that an access device is not capable of processing. The gateway and/or server may automatically detect the format incompatibility, and may automatically convert or arrange for conversion of the multimedia information to a format that is compatible with the access device, based upon compatibility information associated with the access device. The conversion may be based upon a set of user-defined quality of service criteria, and may be subject to the control of digital rights management parameters associated with the requested multimedia information. The user of the access device may be prompted when the conversion is expected to impact the quality of the multimedia information being played, and the user may be offered options that permit the user to minimize the impact upon the user.
