When we want to enjoy our favourite entertainment, whether it be streaming, gaming, Blu-Ray disc, or watching free-to-air content, the audio and video signals we see and hear are typically transmitted through a High-Definition Multimedia Interface (HDMI). In the past, audio-visual technology relied on bulky and inefficient connections that required separate parts or connectors for audio and video, and used analog data. However, with the advent of the digital age, a new kind of connection was needed.

In 2002, some of the industry’s leading companies, including Hitachi, Panasonic, Philips, Sony, and others, collaborated to develop HDMI 1.0. HDMI provided several advantages over its predecessors. It allowed for faster data transfer, utilised smaller and more efficient connectors, and introduced enhanced capabilities and additional features. Consequently, HDMI quickly replaced older connection types and became the standard. By 2009, HDMI ports were installed in over 600 million devices, and by 2021, that number reached nearly 10 billion.

HDMI has become a crucial tool in the world of Audio-Visual technology. The latest version, HDMI 2.1, is a powerhouse that supports high-resolution formats like 4K and 8K video, dynamic HDR (High Dynamic Range), and eARC. It can transfer information at lightning-fast speeds of up to 48Gbps! It’s important to remember that the type of HDMI connection is determined by the equipment or device you’re using, not the cable itself. However, the cable’s capacity to handle all the required data is essential, just like a garden hose needs the right fittings and enough width to water your plants effectively.

One of the amazing features HDMI introduced is the Audio Return Channel (ARC). In the past, we needed separate connections for audio and video cables, which is inefficient and severely limited the output quality. ARC, added to HDMI in 2009, allows digital audio to travel alongside visual information through a single HDMI connection. This means that sound from your TV can be sent back to your AV Receiver or Soundbar using that same HDMI connection, eliminating the need for extra cables. It’s a convenient and streamlined solution!  The latest version of ARC is called eARC, which stands for enhanced Audio Return Channel, and allows for uncompressed audio and formats such as DTS:X and DOLBY ATMOS to be played via your sound system, letting you enjoy the movie-theatre quality audio coming from your tv or device.
