Abstract

A computing device for low-latency multimedia using dual wireless adapters, comprising a first wireless adapter connected to a Wi-Fi access point; a second wireless adapter connected directly to a plurality of wireless devices; and an operating system comprising programming instructions stored in the memory and operating on the processor and configured to: receive streaming multimedia via a wireless network from a media source, using the first wireless network adapter; and send at least a subset of the streaming multimedia at least one of the plurality of wireless devices using the second wireless network adapter.

Claims (29)

1. A computing device for low-latency multimedia using dual wireless adapters, comprising:

a processor;

a memory;

a network interface controller;

a first wireless network adapter connected to the network interface controller and to a Wi-Fi access point using a first antenna and a first frequency;

a second wireless network adapter connected to the network interface controller and directly via Wi-Fi to a plurality of wireless devices using a second antenna and a second frequency; and

an operating system comprising programming instructions stored in the memory and operating on the processor and configured to:

establish, using the network interface controller, a streaming multimedia session;

receive, at a transport layer of the operating system from the streaming multimedia session, streaming multimedia from the Wi-Fi access point, using the first wireless network adapter;

instruct the transport layer to provide at least a portion of the received multimedia to the second wireless network adapter; and

send, using the network interface controller, at least the portion of the streaming multimedia to at least one of the plurality of wireless devices using the second wireless network adapter.

2. The device of claim 1 , further comprising a media management subsystem configured to identify a subset of streaming media that is to be delivered wirelessly to latency-sensitive devices.

3. A computing device for low-latency multimedia using dual wireless adapters, comprising:

a processor;

a memory;

a network interface controller;

a wireless network adapter operating on the computing device and comprising at least a wireless radio configured to operate on a plurality of channels within a specified frequency band; and

an operating system comprising programming instructions stored in the memory and operating on the processor and configured to:

establish, using the network interface controller, a streaming multimedia session;

receive, at a transport layer of the operating system from the streaming multimedia session, streaming multimedia from the Wi-Fi access point, using a first channel of the wireless network adapter, the first channel using a first frequency;

instruct the transport layer to provide at least a portion of the received multimedia to the second wireless network adapter; and

send, using the network interface controller, at least the portion of the streaming multimedia to at least one of the plurality of wireless devices using Wi-Fi via a second channel of the wireless network adapter, the second channel using a second frequency.

4. The system of claim 3 , further comprising a media management subsystem configured to identify a subset of streaming media that is to be delivered wirelessly to latency-sensitive devices.

5. A method for low-latency multimedia using dual wireless adapters, comprising the steps of:

establishing, at a network interface controller on a computing device comprising at least a processor and a memory, a streaming multimedia session;

receiving, at a first wireless network adapter operating on the computing device and from the streaming multimedia session, streaming multimedia content from a Wi-Fi access point via a first Wi-Fi wireless network using a first frequency;

instructing the transport layer to provide at least a portion of the received multimedia to a second wireless network adapter operating on the computing device and comprising a second antenna and using a second frequency; and

sending at least a subset of the streaming multimedia to a plurality of devices via a Wi-Fi network, using the second wireless network adapter.

6. The method of claim 5 , further comprising the step of identifying, using a media management subsystem stored in the memory and operating on the processor of the computing device, a subset of the received streaming media content that is to be delivered wirelessly to latency-sensitive devices.
