Abstract: A computing device may broadcast a first message via a wireless interface while operating according to a first network topology. After broadcasting the first message, the computing device may receive the first message via a wired interface. Based on receiving the first message via the wired interface, the computing device may broadcast a second message indicating a second network topology via the wireless interface. Based on receiving the first message via the wired interface, the computing device may operate according to the second network topology.

Abstract: Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.

Abstract: A method for data interchange includes summing up data associated with an electronic document to provide summed up data, representing the summed up data as one or more bar codes, and returning the one or more bar codes for display and data capture via a bar code scan from either a video display or a printed version of the one or more bar codes. The electronic document may be of any number of formats. The summing up may include taking data from multiple information fields to create the summed up data. The data may include data tags or a step of adding data tags to the data to assist in data interchange may be performed.
