Hello everyone,

Often when one speaks of the high definition TV, one thinks about the video and the audio.
But that to say the connector industry

I would like to know what is the cord or the cable that permit to answer to the source really audiovisual HD.
Of course, one separates all accessory of performance of returned it concerning picture: scaler / HD videoprojector.

The opinions are the welcome

HDMI is an (drm) extended version of DVI so there is no audio-visual difference.

Thank you for your precisions.

A thing, what is therefore the interest to possess a HDMI adapter / DVI?

I challenge myself because the S-VHS adapter / VHS or VHS / S-VHS in the domain of the video will never produce the S-VHS.
There would be a real difference between these two products or it is just the convenient side that differs.

Converting s-video to composite isn't lossless because s-video carries the information in a much more accurate way. Both DVI and HDMI carry the video in same format and keep it in digital domain so there is no quality degradation when going from DVI to HDMI or vice versa.

HDMI can carry audio but DVI doesn't carry audio at all.

HDMI has 5 Gbps of bandwidth if that is what you are trying to ask.

Good evening Latexxx

I browsed the web to deepen my approach better.

Apparently, the HDMI hold is at a time "powerful" more convivial and more compact than its sister DVI.
Indeed, it transports 5Gbts, therefore useful at any non pressed signal and, allow (what interested me) a signal audio multi channel (active until 8 channels) or stereo (active until the 192 khz), identical in the MLP.
It is magnificent.
In addition, it is a reality that distinguishes itself of the lounges of the Cedia and the CES Las Vegas, all disconcerted sectors (Plasma, LCD, DVD..) present on big marks: Pioneer, Meridian, Sony, Ayre, Linn, Panasonic, ect,...

In short, to be straightforward i think that this interface who assures The Dialogue between the materials and that can compared himself to a lower-case letter taken numeric péritel is the one of the future: transportation of the audio and of the MD video / HD, a protection against the copy and allow the materials joined to communicate between them.

Sorry for the understanding and the translation.

would less wires increase the chance for cross talk? Obviously there is no chance if these are fiber cables, but it's my limited understanding that they are not.
I highly doubt cross talk would be an issue for either cable under average user conditions.

Regarding how it may be possible for the cable to carry multiple sources, or lets say separate auidio and video. I'm saying this with the signals either coming from seperate sources, or going to separte sources (sources or applications, no difference here).

This would have to be implemented at higher levels than just the cable.

The drivers would have to know which applications the signals are to be sent to.

The cable itself cannot perform this function.

As posted earlier by another, I prefer DVI, simply due to my paranoia concerning DRM.
