Numpty question-Yamaha YSP1000

[dazednconfused]

Hi guys,
back to pick your brains for more information! This is no doubt a dumb question,but why do surround SOUND amps/processors have VIDEO in/out connections?.
I have recently purchased a Yamaha YST 1000 sound projector,which obviously processes the audio side of things,but why does this,and most if not all amps/processors etc. have video socketry as well?
It states in the manual that if you connect the video side of things through the sound projector,you will benifit by enhanced PQ,so one assumes there is some form of video processor onboard-my question is...why?.
I bought the sound projector to do just that-project sound!.As my display is HD,and has HDMI,(which the Yammy does not)-I certainly will not be connecting my HD video through the projector....but then,my tiny brain starts to worry...if I don`t...will there be sync/whatever probs????.....HELP!.

Hey guys.....obviously most of you who have read this question have decided it is not worth answering,whereas others have perhaps not understood it-to those of you with techy type brains,I REALY DO need an answer on this,I need to get the best I can from my kit,and I do not know how....be kind to me fellas

Receivers

These days, receivers have become Audio/Video receivers. Some like the new Yamaha RX-V2600 include advanced video processing and scalling allowing you to take an analog 480i input and dinterlace and unconvert it to 720p and 1080i. This receiver also has HDMI inputs and outputs and HDMI can carry a digital audio signal from the source to the receiver.
Even entry level receivers will convert video from a composite, s-video, or component input and output to component. Many of these features are for convenience allowing the video and audio source to switch at the same time and to allow a single video cable from the TV to the receiver.
Many receivers also use the video output for an on-screen menu which allows users to access the increasingly complicated setup and features.

No, these features do not improve the audio but in same cases can improve the video quality.

Hi JC,many thanks for your reply mate.
I hear what you are saying about receivers such as the 2600,with built-in upscalers etc.,but the bit of kit I am on about is my Yamaha YST sound projector,which has no HDMI in or out,so it would seem not a good move to connect video through it ??.
My display is a Pioneer plasma with HDMI inputs(it is HD ready),so although I COULD connect video through the sound projector using component,is there any point?-I would have thought it better to go straight from any video source with HDMI to the display??.
My problem is...if I do this,audio will go to one piece of equipment(the Yammy),and video straight to another(the display)-could this cause sync probs...or not??...or any other probs,come to that??.
cheers,dave.

Hey fellas-is this a more difficult question than I first thought??
Someone help me out here...PLEASE?

Well I will take a stab at it for you I guess.

From what I understand the only benefit of routing your video through a reciever (and I understand you have the YSP-1000 not exactly an AVR but for this the answer should be the same) is that when you switch sources (say from cable TV to DVD) the video and audio will both follow without having to switch the TV to a different input because the AVR will switch both the video signal and audio signal.

That is my understanding. Other real benefit though.

That speaker system is an 'all in one' processor and speaker system. So you would want to run the video through it for ease of switching as malvado78 described.

Hey guys,many thanks for your replies-I understand your points,but still have a problem with this.
If I do go the rout you suggest,it will mean I will loose the digital bennefits of the HDMI connection(as I mentioned,the Yammy does not have HDMI )-would you consider it worth that loss to gain ease of switching ? would the switching process you mention be a real pain in the but?.
cheers fellas,Dave G.

Universal Remote

If you have a programmable remote like a Harmany, you can set it up to switch the TV's video input at the same time as the receiver's audio input making the switching feature a non-issue.

Also, the audio sync issue you describe can be adjusted using a setting on the YSP regaurdless of whether your are routing video through the receiver (YSP) or not.

I asked exactly the same question and was told that you should definitely run an HDMI cable straight from the source to the screen if your receiver doesn't have the connection.

The benefits are the switching, as mentioned earlier, but also the practical side. My plasma is hung on the wall. Looks great (just like the ads) until you start hanging loads of wires underneath!

By running all your source wires to the receiver, you only need to run one wire for each type of video to the monitor. So if all your video has component sockets, they can all run to the receiver, and just one from that to the screen. It looks a lot neater.

And the good bit is,I came up with my user name quite independantly -I have only recently noticed yours.......you sure you did not rip me off???

Great answers JC,they look the dog`s danglies to me-as I have said before,you are a true gent(and a lot smarter than me )
I do not have a pr.remote as you describe,but I sure as hell can get one!.
Many thanks again my friend,Dave G.

Thanks for your help Geoff,all good thoughts to add to my growing knowledge-might even get the thing up and going if I am not careful
