To present multimedia data, a communication path is established through a selectively separable electrical connector over which encoded multimedia data are conveyed to a multimedia presentation device. An order for a multimedia data file is transmitted to a multimedia source device through a wireless communication interface that is selectively separable from the multimedia presentation device at the electrical connector. The multimedia data file is received over a wireless communication channel through the wireless communication interface upon successful completion of a financial transaction for payment of the multimedia data file. A processor that is selectively separable from the multimedia presentation device at the electrical connector encodes the multimedia data of the received multimedia data file into a format compatible with presentation capabilities of the multimedia presentation device. The encoded multimedia data are conveyed to the multimedia presentation device via the communication path established through the electrical connector.
