What You'll Learn
HDMI cables carry audio and video signals
HDMI, or High-Definition Multimedia Interface, is a cable that can carry both audio and video signals through a single cable. This makes it a highly efficient connection option for modern entertainment systems. By carrying audio and video signals in one cable, HDMI reduces cable clutter and simplifies the setup of home entertainment systems. This is in contrast to component connections, which require multiple cables to achieve the same result.
HDMI cables support high-resolution audio formats like Dolby TrueHD, DTS-HD Master Audio, and even more advanced formats such as Dolby Atmos. This allows for uncompressed, studio-quality sound, which is a significant improvement over older formats like Dolby Digital and DTS. HDMI inherently syncs audio and video passing through the cable, ensuring that there are no delays between what you see and what you hear. This is crucial for maintaining the integrity of immersive viewing experiences, particularly in high-action media.
HDMI cables are designed to transfer audio directly from the source in its purest digital form, which allows for the transfer of a lossless audio signal. This means that the signal is less prone to signal loss and interference compared to analogue signals. HDMI also has a significantly higher bandwidth than other digital cables such as Toslink Optical cables, which allows the cable to support the latest lossless audio formats.
HDMI's ability to carry both audio and video signals in a single cable makes it a convenient solution for connecting devices like Blu-ray players, gaming consoles, and computers to displays such as TVs and monitors. It delivers superior picture quality, surround-sound audio, 3D support, and more. HDMI also supports high-definition content protection (HDCP), which is required by many high-definition downloads and Blu-ray discs.

HDMI supports high-resolution audio formats
HDMI (High-Definition Multimedia Interface) is a highly efficient connection option for modern entertainment systems. It carries both audio and video signals through a single cable, reducing cable clutter and making it easier to manage connections between devices.
HDMI's ability to transmit high-definition audio formats allows for uncompressed, studio-quality sound, a significant improvement over older formats such as Dolby Digital and DTS. It inherently syncs audio and video passing through the cable, ensuring no delays between what you see and what you hear. This is crucial for maintaining the integrity of immersive viewing experiences, especially in high-action media.
HDMI has gone through multiple revisions since its introduction, with each version adding new features while maintaining backward compatibility. Newer versions include advanced capabilities such as 3D video, higher resolutions, expanded colour spaces, and the Audio Return Channel (ARC), which allows audio to be sent from a display back to an audio system over the same HDMI cable.
HDMI 2.1 introduced the Enhanced Audio Return Channel (eARC), which provides support for higher-quality audio bandwidth and speed. It also introduced Display Stream Compression (DSC), a visually lossless compression for ultra-high-definition (UHD) video. With DSC, an HDMI 2.1 cable can support a maximum compressed bandwidth of 128 Gbps, sufficient for 10K resolution.
