![]() Every few seconds - yes, EVERY FEW SECONDS - the two devices have to pass these codes back and forth or everything stops.ĭevices at the time just couldn’t handle HDCP. It then creates secret passwords that are shared at the beginning of every “event,” such as when you turn something on or off, play content, change channels, wipe your nose, whatever. HDCP works by scrambling a digital signal in a way that it does not lose quality. In short, it was a mess from the beginning. It’s an incredibly complex set of shared secret codes, timing parameters, and automated decision processes. Almost immediately, problems ensued.Īn HD digital audio and video signal can be copied with no loss of quality, and so content providers lobbied successfully to get HDCP (high-bandwidth digital content protection) included in the HDMI standard. The HDMI connector was designed in 2002 and went into production in 2003. HDMI started with a great idea: one connector, easy to attach and remove, that carried digital audio and video. The cables were traditionally red, green and blue which wasn’t confusing at all… except that most people thought that the signal was broken into components of red, green and blue and it wasn’t.Īdd to all of this, neither cable carried sound which meant another pair of cables for sound and the potential for a delay between sound and picture. The information was analog, meaning that it was subject to RF interference and line loss. At least they carried digital information so the picture quality was great, when they worked.Ĭomponent cables broke the HD signal down into three parts and put it over a triplet of cables. The little pins broke easily, the cables were delicate and expensive. The connectors were like fishhooks, and it was impossible to remove one without snarling every other cable you had. It’s no surprise that neither cable really represented what the customer wanted.ĭVI cables were potentially the worst idea for HDTV ever. Component was created by home theatre geeks, the same people who brought you Betamax and LaserDiscs. DVI was created by computer programmers… the people who brought you floppy disks and Windows95. Let’s take a look at how HDMI evolved.īefore HDMI, there was DVI and Component. HDMI has not always been the best choice, and if you have older equipment, it may not be the right choice for you. It is reliable, cables are inexpensive, and it’s usually the right choice for connecting video sources like cable and satellite receivers, Blu-ray disc players, and IPTV boxes to TVs. HDMI is the standard for single-cable, HD audio and video today.
