Like Wi-Fi and Bluetooth protocols, HDMI is also a standard or set of preordained rules governing video, audio, and data communication between consumer electronics. While every compatible device will have an HDMI port and require an HDMI cable, High-Definition Multimedia Interface (HDMI) is more than just an audio/video interconnect. HDMI primarily serves as the single cable that interfaces with virtually every single piece of equipment in your home theatre setup, while eliminating the need for several different cables and interconnects. HDMI (High-Definition Multimedia Interface) is a new interface that has enough bandwidth to carry high-resolution video, uncompressed multi-channel audio, Ethernet (for internet access), and additional digital data (including digital handshake data for anti-piracy measures) upstream and downstream. This requires them to pay licensing fees and abide by strict rules regarding quality, validation, and logo requirements. The standard is now maintained with inputs and engineering resources contributed by the HDMI Forum comprising 83 electronics stakeholders from various technology sectors, ranging from consumer electronics (LG) to streaming video providers (Netflix).Īdditionally, it also boasts of nearly 2000 more companies that have registered as HDMI adopters. The HDMI specification is the fruit of seven founding companies (Sony, Hitachi, Toshiba, Panasonic, and others) joining forces to standardise the means to connect modern digital devices with digital flatscreen displays that were rapidly replacing existing analogue CRT televisions. Unlike most exclusionary corporate affairs, HDMI is the consumer electronics equivalent of Marvel’s Avengers franchise. Fixing a mess caused by proprietary cables with another proprietary cable might sound like a bad idea, but there’s a method to this apparent madness. Their answer was yet another proprietary connectivity standard called HDMI. The major home theatre players soon realised that it would be impossible to make their products appeal to consumers without slaying the cable spaghetti monster their fragmented connectivity standards had created. It didn’t take long for the rear I/O panel of an AV receiver in the average home theatre setup to have nearly as much cable spaghetti as a poorly maintained data centre. The dawn of the digital era in the home entertainment space saw different brands introducing their own proprietary formats each with their own cables, interconnects, and digital standards of communication between devices. That’s precisely why will dive deep into the HDMI ecosystem to understand what makes HDMI tick, and how the various versions stack against each other. But, in doing so, the various iterations of HDMI have ironically become increasingly complicated. In its 20-year history, the now ubiquitous interface has gradually evolved to mitigate the mess of cables plaguing our gadgets. However, HDMI is more than just a cable or a port on your consumer electronics gadget. The more enterprising ones among you may even have used it to bring internet connectivity to your home entertainment devices. You probably have already used an HDMI cable to connect your monitor to a desktop PC, a laptop, or a PlayStation console to your home theatre system. Unless you happen to be Amish, it is quite likely that you own more than one HDMI-capable device. Since the inception of HDMI (High-Definition Multimedia Interface) in 2002, the proprietary audio/video interface has been used in more than 10 billion devices.
