Sorry mike ,i'm answering a question,but it isn't too difficult to understand this is deliberate noise added to the video output,if you're an english speaker you will know what the word ADDED means,sorry,its the only way i can explain,so no offence meant to anybody.

hI,THESE comments are like the rhyme called the emporers clothes,when the emporer went around nude and his subjects didn't dare tell him he was unclothed cause of the consequences,if you dont want the accept the answer,don't,as for working in the vcr industry,you were'nt on the technical side,i can send u a dvd showing this noise if u give an address,otherwise i rest in peace.

What more can i say,put your box on to qvc,you will see the spurious outlines,look behind the presenters outlines,you will see a shadow,what more can i say,you're a non believer.Just study whats behind the items in the picture.n....................

hi,suggest you scope the output,you'll see the spurious signal or get the circuit diagram,incidentally some of the non record boxes dont have this nonsence added so if it spoils the game,get one..............

REAlly,if you are experienced as you say and dont want to see outcome then that speaks for itself,you are concerned that i may be correct and that yr position on this would be compromised,you havent given me any plausible reasons so i don't accept you are an experinced electronics engineer,if u were,then u would be curious to see what is happening.You are supposed to unbiased on this and able to advise non tech people on what is happening.

Ok mike,lets explore this,this circuit was orginally designed for copyright reasons,to enable objections to
recording copyright items on vhs/betamax/video 2000,the things was you could record a degraded master copy but extra generations would be completely degraded,which is true,vhs pictures are delibrately degraded,the public are told its shortcomings are technical but look at the diagrams ,they are not.To prevent further copying noise was added,called expander noise,a diode connected to the power rail conducts noise through an inductance and a capacitor to the video,when you try to record another copy its all a mess,hence mission done.In rec ent times the noise has been modified various ways,like digital blocks and has spread into sd cameras,lcd receivers,dvd recorders,plasma tv's,that why i have an 18yr old crt tv so at least the tv display is clean,theres nothing in the video circuit that adds noise.We come to the question,why add this noise,my thought,well firstly we want to sell some nice hd gear so if we degrade the pictures then possibly the public will buy hd and cause even sky has got in the act,if you connect a sky box,suddenly the noise disappears,what can you say,you buy a nice plasma tv,plug into the analogue inputs and you get a vhs looking picture staring at you,i'm fed with the practise but at least i have the knowlege if needs be to feed the tv from home made video circuitry,so you see their point,they want to sell their hd stuff,perhaps combat copying,its the wallet thing,the machine wants to be fed.Board of trade wouldnt be concerned with this so its the law of the jungle,if you want a nice clean tv to look at,you've got to have the technical to do it...........hope that helps,mike,i don't want to be at conflict with you.....n.

Mike.sorry.i've often wondered about the moon landings,etc,the video does seem very degraded ,its possible,indeed there's a film about.Not really sure,sometimes something thats not logical,turns out to logical,the flags for example.............n

ok,MIKE,whats the point,you've rejected anything i've said,if you dont want to try to understand,what can i say,its nothing to do with macrovision,etc,LCD tv abound,you've changed everything i've said,this is why the press is dying on its feet,too many witchunts against the local population and yr copy is typical of political correctness,i once made a complaint to BBc about hitting tube tv's with a hammer,i know about but got a pc responce about it ,its fine ,etc,i've broken tubes and had to get out of the way when the glass broke,its chased me out of the garage.Anybody hitting a tube will get the full force of glass coming their way,would cut you to pieces,if you want to be pc,then there's nothing more i can say.n...........

Mike,its pointless but its a money thing,nothing else,the next version is better than the last,tv's dont rust like cars and its an attempt to keep the money rolling,after all,the md does want the latest version of a private yacht ,etc,its Money,to keep it flowing,its MONEY<MONEY,nothing else...............You must buy the latest version cause we need yr money.n...........

I have told you the truth of the matter,if you can't accept it,TOO bad.
