![]() The HDMI format is a great advancement for the home theatre, however its implementation has been somewhat messy. This means that new consumer electronics will all have the same connector regardless of what country or region they are manufactured for. With High-bandwidth Digital Content Protection (HDCP) as part of the HDMI specification, consumers could now enjoy up-conversion of standard DVDs and the high-def content of Blu-ray without easily being able to duplicate high definition copyrighted material, and thus keeping the movie studios happy.Īnother benefit is that HDMI has been accepted as a worldwide standard. Two-way communication (of device command controls) is supported, which can greatly ease the configuration and operation of multiple HDMI devices.Īlthough component cables do have the bandwidth to carry high definition video (up to 1080i), content providers like movie studios, didn’t want to give consumers (or pirates) an easy route for copying high definition movies. There is also no interference within the cable itself. ![]() Since the HDMI signal is purely digital, it eliminates the quality degradation in the digital to analogue (and back again) conversion process. The high bandwidth of HDMI allows for transmission of up to 1080p content (component cables top out at 1080i). One cable, that carries both audio and video signals, can do the job that previously required up to eleven separate cables. HDMI is a consumer friendly connection that simplifies and improves the home theatre. The snake pit of cables behind many home theatre racks would give Indiana Jones a heart attack. Now add the cables from receiver to TV, cable box to receiver and a gaming console or two, not to mention a dedicated CD or universal disc player. And that’s just from a DVD player to an AV receiver. We reached the point where attaining the highest quality audio and video required a component cable with three(!) connections for the video signal and up to eight(!!) cables for audio. ![]() The advent of the DVD format made the home theatre a realistic option to movie theatres, but it also made things more complex to install. It used to be that hooking up a home theatre involved three cables one for video and two for audio. The good news is that HDMI is backwards compatible with DVI, the bad news is it won’t work 100 percent of the time (more on this later). There were also a number of consumer televisions and home theatre projectors released with DVI inputs. It is the evolution of the Digital Video Interface (DVI).ĭVI is now used on modern computer monitors and graphics cards. HDMI (High Definition Multimedia Interface), the highly touted but much maligned next generation audio/video connection has been around since late 2002. ![]()
