Why do we need HDMI cables?

post #1 of 5
Thread Starter 
Ok my knowledge of this is very small but if Ethernet can carry an HDMI Signal Why do we need expensive HDMI why cant we use the much cheaper Ethernet?

HDMI requires dedicated hardware and has some overhead as far as encoding and transmitting the data, more so than your typical Ethernet controller. While its true that this data can be encoded for transmission over CAT5 cable, doing so requires additional expense and often outweighs the savings on the cable. Also, check Amazon for HDMI cables. A 15 foot cable can be had for five bucks, which is not asking much at all.

HDMIs notoriously expensive price comes from people walk into a Best Buy and get a $59.99 Monster cable that's ridiculously overpriced. Monster and Best Buy profit on consumer ignorance, in a sense.

Yes i know i never bought or will buy those $60 cables But why did we need HDMI If we had current technology that could handle it? And why dont we switch to display port witch i understand as a far more superior bandwidth?

HDMI sends an encrypted signal. Essentially, it means that you can't buy a Blu-Ray disk and a Blu-Ray player, then feed the output cable into a capture device and record the output. At least, that was the intention. HDMI took a half a decade of development, and the hacker communities of the Internet had it broken within hours of release. The idea was to keep the average Joe from being able to record his videos and back them up somewhere as a form of DRM. Didn't last long though. wink.gif

DisplayPort is unencrypted and can be captured with far greater ease than HDMI. The reason HDMI has the hold it does on the market is because Sony (who is FAR bigger than most people realize) as well as a bunch of other media companies supported its use from day one and in fact helped to pioneer it.
