US 2019/0104256 A1 · REMOTE CONTROL ACTIVITY DETECTION

Abstract

Embodiments described herein enable detection of remote control activity. For example, a determination may be made whether an RF remote control is in use by detecting a non-RF signal transmitted by the RF remote control. The non-RF signal need not actually control any device, but it may be used to detect when the RF remote control is in use. An AV switch may detect an RF remote control is in use by detecting a non-RF signal. For example, when a user uses an RF remote (e.g., to control an STB with an RF signal) the use may be detected by detecting a non-RF (e.g., an IR signal) signal and the AV switch may use the detection, for example, to control a TV (e.g., turn on), control the switch (e.g., port selection for a TV to display STB output) and/or other devices.

Dependent claims

A system for controlling a device, the system comprising:

a receiver;
a transmitter;
and
control logic that is operable to:
determine that the receiver has received a non radio-frequency (RF) signal transmitted by an RF remote control device that is operable to control a first device among one or more source devices or one or more sink devices, wherein the RF remote control device is programmed to transmit the non-RF signal in response to a user interaction with the RF remote control device;
in response to determining that the receiver has received the non-RF signal, determine that the RF remote control device is in use;
and
in response to determining that the remote RF control device is in use, cause the transmitter to transmit a control signal to a second device.
