Newsmeldung von slashCAM:The problems of HDMI of thomas - 13 Aug 2007 22:16:00 The HDMI standard for protected transmission of high-resolution images is with some problems. This article tells the story of the HDMI interface - beginning of the design weaknesses of DVI to the functioning of the more recent HDMI standards, and its limitations - particularly with regard to the maximum cable length.

Antwort von Valentino:
Nice article about HDMI, if somewhat synonymous in Basic Electrical Engineering is required for this. But in principle is HDMI for long distances completely unusable. I would always easier for the customer when he was only one or two coaxial cable should then. There are credible of any company's approach HD-SDI for ordinary consumers to make tasty, but nothing is believable draus become. But not everything is good, is synonymous with VHS vs. see. Betamax.
What bothers me a bit YUV in the article not as an alternative to HDMI is called.
Antwort von WoWu:
The article is loosely written .... too loose, because he holds s.allen corners and edges glaring mistakes ... he is content with caution .. I admit that quite Valentino ... you should bring some knowledge ... would have been nice if the synonymous for the author would have been applicable.
Antwort von WoWu:
.. perhaps even a word ... if the specifications closely, you will quickly find that HDMI 1.3 the bandwidth of the data so far 4.95 Gb / s (165 Mhz) to 10.2 Gb / s (340 Mhz) doubled. This is a much wider range of colors possible.
So far, HDMI 1.2 was only 24-bit (RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2), 30 bit and 36 bit (YCbCr 4:2:2) possible. . The higher data rate for HDMI 1.3 allows synonymous color depth of 30 bit, 36 bit and 48 bit with 10/12/16 bits per color component (RGB 4:4:4, YCbCr 4:4:4). HDMI 1.3 supports additional to existing formats SMPTE 170M/ITU-R BT.601 and ITU-R BT.709-5, the new xvYCC color space model in the IEC 61966-2-4 standard is defined, and thus enables a very large color space to improve the color. Improved depth has the following advantages: The ability of HD displays, display billions of colors is now synonymous with the transmission protocol of HDMI support.
The possibilities of resolution by more than 400%. To 720p HDTV increased. Higher refresh rates (frame rates) are possible: up to 120 Hz.Über this interface is not only possible, datenkomprimierte transmit signals, but the synonymous uncompressed signals over HDSDI example, a double-link would have required.
Perhaps more to the Sound: 1.2 Even transmits audio data up to 192 kHz with word widths of up to 24 bits at up to 8 channels. HDMI for Dolby Digital 1.3 were pros and Dolby TrueHD recorded.
And much more .... The article says nothing about the contents and s.CAT 5 cable around to justify meckert still no article.
Quite apart which is the problem in the broadcast world is already solved and transmission length of 90 m made safe.
So ... world lives in what the author actually?
I would make the article from the Forum recommendations to take out.

Even in Broadcastberreich such key data as 30 or 36 bit absolute overkill and the consumer is what is really still a different view? Almost the same thing as with FullHD.
Antwort von Kenshin:
The question which HDMI version now makes sense is in practice at least for HD-DVD or Blu Ray players are not likely because an update is done once the car keys need to be replaced
Antwort von WoWu:
Valentino .. hello ..
... the question, "Who brings what" we must not make .... because if we once again make a new interface, which only the technical developments of the next 10 months was holding has been the target. Therefore, it is very good that we finally have a defined interface, which holds a couple of years ... synonymous way, what the desire of the industry. Therefore, the definition of all of us something ... and we must stop, not over the rim to want to see.
Technique is something very dynamic and only if far-reaching objectives are defined, is synonymous planning both for the industry, as synonymous to the consumer.
No, nei, I had quite s.dem Standard suspend other things than just that, the old cable schrottigen no longer be able to use.
And the article was entirely the problems of a cable adapter manufacturer, which is precisely on the fact lamented his old cable is not more "verscherbeln" and now to be able to produce new cable (can) be.
He has completely forgotten that the (HTMI) standard, but nothing synonymous with the cables and their specifications, has to do, because to solve the problem really is the Manufacturer.
So the only message that a user of the article can take: "You can HTM1.3 at Your old cable no longer use" .... Big Deal!
