Patent 12067384 was granted and assigned to Vizio on August, 2024 by the United States Patent and Trademark Office.
Systems and methods for updating firmware in an audio device, such as a soundbar, operatively connected to a Smart TV, are shown and described. Firmware update data is transmitted to the audio device via an audio return channel (ARC) of an HDMI cable. In certain of the systems, the firmware update data is transmitted to the audio device when no audio is being transmitted to or played by the audio device. In other systems, the firmware update data and real-time audio data are multiplexed by the Smart TV and are sent to the audio device via the audio return channel for subsequent demultiplexing and playback of the audio.
