HDMI ARC stands for "High-Definition Multimedia Interface Audio Return Channel." It is a feature of HDMI that allows audio to be sent from a television back to an audio system using the same HDMI cable that is used to send video signals.
With HDMI ARC, you can connect an audio system to a television using a single HDMI cable, instead of using multiple cables for audio and video. This makes it easier to set up and connect your home theater system.
When you connect an audio system to a television using HDMI ARC, the television sends audio signals back to the audio system through the same HDMI cable that is used for video. This allows you to use the audio system to play audio from any device that is connected to the television, such as a cable box, streaming device, or gaming console.
HDMI ARC also supports a range of audio formats, including Dolby Digital, DTS, and PCM. This allows you to enjoy high-quality audio in your home theater system without the need for additional cables or connections.
Overall, HDMI ARC is a convenient feature that simplifies the setup and connection of your home theater system, making it easier to enjoy high-quality audio and video.
