Rookie Question re: HDMI

[Carlm1970]

Assuming only one HDMI component (ie. DVD), is there any advantage of connecting HDMI out from DVD into HDMI in of my Receiver and subsequently running HDMI out from the Receiver and into the TV?

In other words, if I went direct HDMI out from DVD to TV, while running separate optical audio from DVD to Receiver would that not accomplish the same performance?

If so, the latter option spares the higher cost of an extra HDMI cable.

Thanks and my apologies for what may appear to be a novice question.

Only if you have multiple sources.
Yes.

The only advantage is that you would be able to change the TV input and the receiver with one button. Good if you have young kids or others in the house who are a little behind on their technology.

Performance wise, you are only making things worse. You have added a cable and a receiver, thereby tripling your chance of something bad happening in the signal path. This of course assumes that the receiver actually does nothing other than carry the signal. If it does any processing, then you have gone well past tripling into the dark place....

You should also remember that inefficiencies multiply, not average. If each cable was 96 % efficient, and your receiver is 96 % efficient, you are not 96 % efficient.

You are actually .96 * .96 * .96, or only 88 % efficient in getting the signal to the display.

You are always best sending video to the video place and audio to the audio place !!!

Clear explanation. Thank you. So just to be sure...are you suggesting that a receiver (lets assume a higher end) has no ability to improve video performance of dvd?

 

[Johnd]

Yes...but it is not a suggestion, it is a fact. The player's job is to read to the best of its' ability the disc and relay it to the display. And the more connections you have (particularly hdmi which are notoriously prone to looseness right now), the more signal you lose (usually negligible) and the more susceptible your cabling is to become dislodged.

If your receiver has a Faroudja or similar chip in it AND your DVD player does not, it will get you a de-interlaced picture (480P). If your DVD player DOES have a de-interlacer, you would be wasting your time. The easy way to check is see if the DVD player says "Progressive Scan" in the manual or on the box.

Didnt he say that? He said he should run HDMI from DVD to TV and Audio from DVD to AVR. Isnt that the jist your response as noted in your quote above?

Sorry about jumping in on the thread, but I also had the same confusion as Carlm1970. As I am looking at buying a new receiver, I was pretty much sold on the Denon 3805 or the yammi 2500, but then I started reading reviews on the 3806 and 2600...with the increased video capabilities, i.e. HDMI.

It would seem after reading these threads, that as long as I have a quality DVD player, I can just bypass the receiver's video technology by going direct from DVD to TV and using my receiver for the audio portion and I'm farther ahead. This way I don't have to worry about spending extra money on a receiver that only has 1.1 HDMI technology. I guess this makes me wonder if I really even need to invest in the 3805 or 2500, as long as I have a great set of surround speakers and a good DVD/TV combination. Maybe I can settle for the Denon 2805 or similar. Any thoughts? Thanks.

i have noticed a better and more adjustable audio/video sync when running HDMI/DVI through my av reciever. another bonus is bieng able to use more than one digital video source (DVD player and HD-DVR for example) since alot of HDTV's have only one HDMI input. by the way most up converting dvd players lip sync adjustment only works when using analog audio(not optical)

Last time I checked (new rap-based English may have changed this) but a sentence that starts with "In other words, if" and ends with a question mark means that someone is wanting confirmation of what they think.

My "jist" provided that confirmation.


please feel free to enlighten me if the rules have indeed changed.

One other advantage is the possibility of only running one cable to the receiver for audio and video via HDMI.
