US Classification:

707816, 711170, 707E17005, 711E12001, 711E12002, 711166

Abstract:

A memory allocation message for each primary memory allocation in a primary memory made by a primary processor is received at a hardware memory management module. A representation of each primary memory allocation is allocated within a second memory in response to each memory allocation message. A determination is made, based upon the allocated representations of each primary memory allocation within the second memory, to free a primary memory allocation in the primary memory. A memory free message is sent to the primary processor instructing the primary processor to free the primary memory allocation in the primary memory.

International Classification:

G06F 15/173

US Classification:

709225

Abstract:

An example multimedia playback device is connected to a network that is configured to not provide an indicator of existence absent a command from the multimedia playback device. The example playback device is to initiate a connection phase for a device to connect to the hidden network based on a user action at the playback device. The example playback device is to reveal a network access point in a connection phase and authenticate the wireless device with the audio network for limited connectivity to the network during the connection phase. The example playback device is to disconnect the wireless device from the audio network and accept a connection of the wireless device to the audio network in an operational phase, the connection enabled using information provided to the wireless device during the connection phase and without the limited connectivity provided in the connection phase.

International Classification:

H04B 7/00

US Classification:

381 81

Abstract:

Systems, methods, apparatus, and articles of manufacture to provide for low-latency delivery and playback of audio are disclosed. In one embodiment, an example audio system includes multiple playback devices including a primary device and one or more secondary devices, whereby, the primary device establishes and controls a peer-to-peer network that connects, wirelessly or wired, to each of the satellite devices. An example audio device contains a channel selector, a control interface, and an audio interface. In some embodiments the control interface is used to transmit control information to another device on a first frequency channel, and the audio interface is used to transmit audio information to another device on a second frequency channel.

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.

International Classification:

H04L 29/06
H04W 76/10
H04W 48/18

Abstract:

An example playback device includes programming for executing functions including, while connected to both (i) a local area network and (ii) an audio playback network configured separately from the local area network and arranged for playback of media content via at least the playback device, receiving from a network device via the local area network, a request for the network device to connect to the audio playback network. The functions also include, in response to the request, transmitting to the network device via the local area network, a message indicating an identifier of the audio playback network and a password for accessing the audio playback network. The functions also include exchanging one or more messages with the network device via the audio playback network to authenticate the network device for the audio playback network and receiving an audio playback command from the network device via the audio playback network.
