Abstract

Functionality of a multimedia presentation device is enhanced by establishing a communication path through an electrical connector that is selectively separable from the multimedia presentation device. Output streaming media are conveyed to the multimedia presentation device over the established communication path. A wireless communication channel is established over which input streaming media are received from a multimedia source device. Multimedia data of the input streaming media are stored in a memory that is selectively separable from the multimedia presentation device at the electrical connector. A processor, which is also selectively separable from the multimedia presentation device at the electrical connector, retrieves the multimedia data stored in the memory and the retrieved multimedia data are conveyed to the multimedia presentation device as the output streaming media on the communication path to the multimedia presentation device through the electrical connector.
