Samsung patents wireless display adapter that checks signal strength

Samsung has been granted a patent for a gateway device that connects a wired source, like a computer, to a wireless display. The device asks the user about their environment to estimate the maximum wireless speed and compares this to the data needed for different video formats. It then identifies which video formats are too heavy for the current connection to send.

Why it mattersThis could help wireless display adapters avoid freezing by automatically selecting video qualities that match the current Wi-Fi or Bluetooth conditions.

In the filing’s own words

A gateway apparatus including a communication circuitry configured to perform a wired connection with a source device and wirelessly connect with a sink device that outputs media; an interface configured to receive a user input from a user or output information to the user; and a controller configured to control the communication circuitry and the interface. The controller is configured to: obtain communication performance information of the sink device and obtain Extended Display Identification Data (EDID) including available output formats of the sink device from the sink device via the communication circuitry, obtain information about an environment in which wireless communication with the sink device is performed from the user via the interface, determine a current maximum transmission rate based on the obtained communication performance information of the sink device and the obtained information about the environment in which wireless communication with the sink device is performed, determine a bitrate required to wirelessly transmit data associated with the media in the available output formats included in the EDID to the sink device for output of the media by the sink device, and determine a non-transmittable format among the available output formats, based on the determined bitrate required and the current maximum transmission rate.

What exactly they claim (claim 1)

1. A gateway apparatus, comprising: a communication circuitry configured to perform a wired connection with a source device and wirelessly connect with a sink device that outputs media; an interface configured to receive a user input from a user or output information to the user; and a controller configured to control the communication circuitry and the interface to: obtain communication performance information of the sink device, and obtain Extended Display Identification Data (EDID) including available output formats of the sink device from the sink device via the communication circuitry, obtain information about an environment in which wireless communication with the sink device is performed from the user via the interface, determine a current maximum transmission rate of the wireless communication with the sink device based on the obtained communication performance information of the sink device and the obtained information about the environment in which wireless communication with the sink device is performed, determine a bitrate required to wirelessly transmit data associated with the media in the available output formats included in the EDID to the sink device for output of the media by the sink device, and determine a non-transmittable format among the available output formats, based on the determined bitrate required and the current maximum transmission rate.
