HDMI also transmits sound – The basics

The term HDMI stands for “High Definition Multimedia Interface” and is a digital interface that can transmit both video and audio signals.

• HDMI allows high-definition video content and multi-channel audio signals to be transmitted in a single connection.

• This means that you can use one HDMI cable to transmit both picture and sound from one source to a TV or other output device.

• An HDMI cable consists of several small copper wires that carry digital signals from a source to an output device.

• HDMI supports various audio formats such as stereo, Dolby Digital, DTS and even high definition formats such as Dolby TrueHD and DTS-HD Master Audio.

• When you connect a device with an HDMI connection (e.g. a Blu-ray player) to a TV or other output device, the sound is automatically transmitted via the HDMI cable. This means that you do not need a separate audio cable to transmit the sound. The HDMI cable handles both the video and audio signals in a single connection.

• To ensure that sound is transmitted via HDMI, you may need to adjust the audio settings on your source device. Check the owner’s manual of the device for more information.

• If your output device does not have built-in speakers or you want better audio quality, you can connect the HDMI cable to an external sound system or AV receiver to improve the sound.

• In summary, HDMI transmits not only video but also audio signals, making it a practical solution for transmitting high-quality picture and sound.
