Electronics, Samsung Electronics, Sony Pictures Entertainment
and Valens Semiconductor have been secretly conspiring to kill HDMI.
And today they set their plans into motion, introducing a brand new
audiovisual standard, HDBaseT.
While that name may sound confusing, before you slap your head,
introduce a new kind of cable to your house.Past A/V
standards from industry groups have introduced a plethora of
connectors (S-Video, HDMI, DisplayPort for example), so that makes
this release all the more unusual. Instead of a new connector,
it is based on the Cat 5e/6 network cables, commonly referred to as
"ethernet cables".It supports cable lengths up to
328 feet. The cable can pass HD and 3-D
video signals, as well as data through an integrated 100MBit
Ethernet connection. That data feed should allow for new
internet-connected TV services, such as Google
TV which delivers advertising-funded services to TV
sets.The standard also has many other advantages. For
one, it will help declutter the growing mess of cables in the average
household. By repurposing ethernet cables, it should also
dramatically lower costs, both for the manufacturer and the
consumer.About the only loser in the situation may be
"premium" cable makers like Monster
Cable Products. However, it'll only be a matter of time
before Monster finds a way to throw gold or other precious metals
into a Cat 6 cable and release it as a "premium" HDBaseT
cable.About the only loose end is what mini-connectors will
arise out of this new standard. Currently many smart phones,
such as the HTC
EVO 4G offer mini-HDMI connections. Perhaps more
advanced mini-USB connections will answer that dilemma, though.The
standard will begin its rollout later this year. The majority
of its volume will hit in 2011.
quote: I just wished they'd have gone the USB cable route due to connector size.
quote: your cable does need a certain amount of bandwidth to work properly.
quote: Cable bandwith is about 850Mhz which is more than Cat5e or Cat6. Also cable is compressed, either with H.264 or MPEG2 (older SD tech).
quote: Saying that, every single channel has to be encoded in the same cable, along with internet, analog channels and on-demand services so there is only so much that they can get in there.
quote: Take any kind of cable or wire you want - let's say speaker wire. Get yerself some $100 Monster Cable speaker wire, and a couple $1 extension cords from your local hardware store. Cut the ends off the extension cords, and use them for speaker wire. Compare that to the Monster Cable. There will be no difference. In fact, you could solder coat hangers in the middle of the speaker wire, and the difference would only be discernible to an oscilloscope.Same goes for ethernet cable, HDMI cables, or anything else. HDMI being completely digital, it makes even less sense - but even in fully analog transmissions, like speaker cables, if you believe there is a discernible difference between $100 speaker wire and El Cheapo stuff, you are absolutely fooling yourself.
quote: A digital signal will either arrive at it's destination 100% intact, or it won't arrive at all. Cable quality, unlike analogue, is meaningless.
quote: The maximum length of a standard USB cable (for USB 2.0 or earlier) is 5.0 metres (16.4 ft). The primary reason for this limit is the maximum allowed round-trip delay of about 1,500 ns. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost. When adding USB device response time, delays from the maximum number of hubs added to the delays from connecting cables, the maximum acceptable delay per cable amounts to be 26 ns. The USB 2.0 specification requires cable delay to be less than 5.2 ns per meter (192,000 km/s, which is close to the maximum achievable transmission speed for standard copper cable). This allows for a 5 meter cable.
quote: Wrong. If it's a copper connection, it's still an analog connection, no matter how you say it.
quote: And if the filter is failed in doing their job, your data might be "broken", ie. 0 could be intrepreted as 1, and vice versa.
quote: Well then by that definition, NOTHING is digital and every connection is analog.
quote: In computer architecture and other digital systems, a waveform that switches between two voltage levels representing the two states of a Boolean value (0 and 1) is referred to as a digital signal, even though it is an analog voltage waveform , since it is interpreted in terms of only two levels.
quote: Although in a highly simplified and idealised model of a digital circuit we may wish for these transitions to occur instantaneously, no real world circuit is purely resistive and therefore no circuit can instantly change voltage levels .
quote: Didn't I already cover this? That would cause visible and/or audible corruption.
quote: Connector and cable structure designed to thoroughly eliminate adverse effects from vibration
quote: Read the comments section...hilarious.
quote: But then I realized the cable was blue, so I only gave it one star. I hate blue.
quote: Only unanswered question. What does this mean for HDCP? Will it work the same? Or the CES manufactures basically performing a unholy revolt and giving the finger to content makers.
