Establishing and controlling audio and voice back channels of a Wi-Fi display connection

摘要

Methods, systems, and devices are described for using a back channel for communicating in a Wi-Fi peer-to-peer remote display connection. A Wi-Fi peer-to-peer remote display connection may be established with a source device. Communications may be transmitted from a sink device to the source device using a back channel of the Wi-Fi peer-to-peer remote display connection. The sink device may connect with a plurality of source devices. A plurality of input streams may be multiplexed into a single output stream. The single output stream may be distributed to the plurality of source devices using back channels of the Wi-Fi peer-to-peer remote display connection. In addition, a source device may connect, via a wired connection, with a sink device. Wi-Fi connection parameters may be exchanged with the wired connection. A Wi-Fi peer-to-peer connection may be established based at least in part on the Wi-Fi connection parameters.
