Abstract
Disclosed herein is an infrared fallback mechanism for remote control devices based on the HDMI-CEC capabilities of a target device. When HDMI-CEC is enabled on the target device, such as a display device or any other suitable HDMI sink device, and when a feature is an HDMI-CEC compatible feature, the remote control device can transmit instructions to the target device by transmitting a Bluetooth radio signal (e.g., a Bluetooth Low Energy signal) to a streaming media device, which, in turn, can transmit an instruction to the target device via an HDMI-CEC channel between the streaming media device and the target device. Alternatively, when the HDMI-CEC channel between the streaming media device and the target device is not enabled or when a feature is not an HDMI-CEC compatible feature (as HDMI-CEC is not always available on target devices), the remote control device can fallback to an infrared (IR) mode by directly communicating with the target device in which an IR code is transmitted to the target device via an IR transmitter on the remote control device to an IR receiver on the target device.
