Abstract

Systems, methods, apparatus, and articles of manufacture to facilitate portable playback of multimedia content are disclosed. An example apparatus includes a communication interface to send and receive data via a network connection, the data including multimedia content for playback. The example apparatus includes a memory to store instructions and data. The example apparatus includes a processor. The processor is to search for an available playback network and, if available, automatically connect to the playback network. The processor is to, in an absence of an available network, establish a mobile zone to facilitate multimedia content playback via the mobile zone. The processor is to automatically switch between the playback network and the mobile zone depending upon availability of the playback network to provide content playback via the portable playback device. The processor is to facilitate control and playback of content on the playback network via the portable playback device.
