US 10,455,632 B2 · Dynamic identification of network connection preferences

Abstract

Methods and apparatus are disclosed for device discovery, pairing, and transmission of audio and video media, using preference data shared between a media sender/source node and a media receiver/sink node. In some examples of the disclosed technology, a sink node sends, via a peer-to-peer wireless communication path, a discovery message to a source node comprising a preference indication including an indication of a first one of two communication paths to use for the establishing a connection. The sink node receives a request to establish a connection between the sink node and the source node based on the indicated preference. Based on the received request, the sink node establishes a connection between the sink node and the source node. A selected communication path (e.g., peer-to-peer wireless or wireless infrastructure) can be indicated as preferred, along with additional parameters for the media connection.

Dependent claims

A method comprising:

with a sink node adapted to receive data via a wireless peer-to-peer communication path:
via the peer-to-peer wireless communication path, sending a discovery message to a source node comprising a preference indication including an indication of a first one of two communication paths to use for establishing a connection;
receiving a request to establish a connection between the sink node and the source node, the request being based on the indicated preference;
and
based on the received request, establishing a connection between the sink node and the source node.

2 more elements

A system, comprising:

(1) a source node, comprising:
a wireless network interface,
a video encoder configured to transmit encoded video via the wireless network interface,
memory, and
a processor configured to execute computer-executable instructions stored in the source node memory that when executed cause the source node to perform a method of transmitting video, the source node instructions comprising:
instructions to receive preference data from a sink node encoded in a peer-to-peer protocol with the wireless network interface;
instructions to send a request to establish a connection to the sink node, the request being based at least in part on the preference data, and
instructions to establish a connection between the source node and the sink node;
and
(2) the sink node, comprising:
a wireless network interface configured to receive data from the source node wireless network interface encoded according to the peer-to-peer protocol,
a display interface,
a video decoder configured to decode video received from the source node and transmit the decoded video to the sink node display interface,
memory, and
a processor configured to execute computer-executable instructions stored in the sink node memory that when executed cause the sink node to perform a method of displaying video, the sink node instructions comprising:
instructions to evaluate two or more communication paths to the source node, the preference data including information to establish a connection to the sink node via each of the two or more communication paths, and
instructions to send the preference data to the source node.
