Čemu služi HDCP?
Evo uskoro sitže dell 2007WFP i sad on za razliku od 2005FPW ima HDCP.

Može neko objasniti šta je HDCP i kakva korist od njega.

Hvala: cheers2

Citiraj:
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copywritten material.
enkripcija HDTV signala, nemres snimat HDTV

edit: nije da ga nemres snimat nego ga nemres gledat na monitoru koji nema to kad snimis, tak nes

Evo uskoro sitže dell 2007WFP i sad on za razliku od 2005FPW ima HDCP.
Može neko objasniti šta je HDCP i kakva korist od njega.
Dolaskom Blue-Ray i HD-DVD diskova dolazi nam i HD (High Definiton) video i industrija je (nezadovoljna mogućnošću gledanja takvog sadržaja na kompu a prestravljena činjenicom da bi ga netko mogao nedaj bože i presnimiti ) razvila novi standard zaštite HDCP (High Bandwidth Digital Content Protection) koji bi napokon trebao stati na kraj piratstvu ... i ovaj put su se stvarno potrudili.

Da bi uopće mogao gledati HD treba ti :
  • HDCP čitač Blu-Ray ili HD-DVD diskova (komp ili samostalni DVD player)
    HDCP monitor (TV, plasma CRT, projektor) obavezno sa digitalnim ulazom (DVI ili HDMI)
    HDCP grafička (samo za gledanje na kompu)
Svaki uređaj mora imati ugrađen jedinstveni set od 40 x 56bitnih ključeva i poseban 40bitni ključ tkz. KSV (Key Selection Vector). U slučaju da je KSV 'provaljen' ide na 'crnu listu' koja se kodira (i zaštičuje DSA algoritmom) na svaki novi HD-DVD ili Blu-Ray disk tako da taj uređaj više neće moći prikazivati nove HD sadržaje.

Ukratko za računala postupak je slijedeći:
OS (Vista anyone ?) tj. COPP driver (Certified Output Protection Protocol) provjerava BIOS grafičke kartice da bi ustanovio HDCP podršku. Nakon što je pronađe razmjenjuju se KSV ključevi i generira zajednički 56bitni ključ koji se poslije koristi u enkripciji. Tek nakon toga se dozvoljava prikaz HD sadržaja. Ako nema HDCP podrške u bilo kom dijelu lanca u najboljem slučaju dobije se lošija slika a u najgorem crni ekran, ovisno o tome kako je odlučio distributer HD sadržaja.
Dodatno cijela komunikacija između uređaja je enkriptirana kao i sam prikaz HD sadržaja a ključevi se obnavljaju svake 2 sec. da ne bi jel'te neko možda presreo podatke.

E sad pošto se industrija trenutno još nateže oko standarda kojim će se distribuirati HD sadržaj (Blue-Ray vs HD-DVD) a još nijedna grafička kartica nema HDCP jer iako je GPU sposoban prikazati HD sadržaj (zato možeš gledati razne HD trailere) ni ATI ni nVidia nisu još ugradili hardware potreban za kontrolu, od same činjenice da ti monitor ima HDCP nemaš ama baš nikakve koristi (još)

The Geek Wants OUT

At first glance
I probably appear to be a somewhat ordinary,
somewhat average looking fellow.
Calm, harmless, at ease.

But this is by design.
You see, it is through decades of research and rigorous training that I have crafted this façade of normalcy.

And now, through intense concentration,
I am able to function in a social setting.
I can speak at length with educated people about
pertinent matters of public importance,
such as literature,
or the current political climate in Europe.

I am capable of conversing with you
without ever revealing that just underneath the surface
of this manufactured veneer
there hides an altogether different person.
A monster, some might say.
My alter-ego.
He is the opposite of the image I project.
He is the antithesis of Cool.
He is the LAST person you want to get trapped in a conversation with.

He is The Geek.
The obsessive science fiction movie watching,
comic book collecting,
Monty Python dialogue memorizing,
Dungeons and Dragons playing GEEK
that I struggle daily to keep hidden from the world.

But The Geek Wants Out.

He want to talk to you.
He wants to give you his doctoral dissertation on why
The Adventures of Buckaroo Banzai Across the 8th Dimension
is the greatest fucking film of all time!

He wants to bitch slap you because
you’ve never seen Big Trouble in Little China.
What? Have you been living in a fucking cave?!

He wants to kick your ass in Star Wars Trivial Pursuit.
And he will.
Because he’s a fucking Geek.

And he wants his toys.
He wants the complete set
in mint condition,
still in the box.
He wants every item on the planet that is even remotely related to Ultraman.
Because Ultraman is Airwolf!

He could give a squirt of piss
about sports or politics or rhetoric.
Such things are of no consequence to him.
What matters is the release date of the next Lord of the Rings movie!

You see, The Geek can’t wait.
The Geek has no patience.
He wants what he wants when he wants it.
And all he wants is stupid shit!

He wants his own Tardis.
He wants his own light saber.
He wants to buy a DeLorean and he wants to drive it 88 miles per hour.

He wants movies.
He wants to see the Director’s Cut.
He wants the impossible to find Japanese bootleg with
6 minutes of never-before-seen footage.

He wants to watch Blade Runner. Again.
He wants to watch Brazil. Again.
He wants to watch A Clockwork Orange.
Again and Again!

But I deprive him of these things, as best I can,
until I can no longer ignore his voice
screaming in my head.

I am Jekyl. He is Hyde.
I am Bruce Banner. He is the Hulk.
Especially the Hulk from issues #272 to #378.

But no longer!
I am putting a stop to all this nerdy shit right now!
I’m an adult, for Christ’s sake!
And this body isn’t big enough for the both of us.
One of us has to go, and it’s gonna be him.
I banishing the Geek forever to the Phantom Zone,
just like in Superman II !
Because, in the end –
there can be only one.

Prvo i to ce se razbiti, prije ili kasnije, a kako je to bilo i s devedejom, dok ce si svi moci priustiti przilice odavno ce biti provaljeno.


A to da nema graficke na trzistu, ne pricaj gluposti!

Prvo oladite malo svi... čovjek je pitao čemu služi HDCP i ja sam mu dao kakvo takvo objašnjenje - uopće ne ulazim u to hoće li i kad biti provaljen ...
Što se tiče grafičke 7950 mislim da je to prva - serija 7 do sad nije imala tu mogućnost a naravno da će se podrška za HDCP morati ugrađivati pogotovo sad kad je Sony prije par dana i službeno počeo sa prvim 'Blu-Ray' filmovima...

Za to je zadužen AACS (Advanced Access Content System) koji se slično kao i CSS bazira na ključevima za enkripciju sadržaja.
Jednostavno rečeno za razliku od CSS-a gdje su svi uređaji određenog proizvođača imali isti licencirani ključ kojim se vršila enkripcija (tako da je povlačenje toga provaljenog ključa bilo nemoguče jer bi onemogućilo svim vlasnicima određenog modela reprodukciju zaštičenog sadržaja) industrija više nije tako bahata i zato AACS polazi od pretpostavke da će bez obzira na sve ključevi vjerojatno biti provaljeni i sad se ključ generira kombinacijom javnih ključeva i hardwerski ugrađenog seta ključeva u svaki pojedini uređaj tako da je moguće onemogućiti točno određeni uređaj. Provaljeni ključevi idu na 'crnu listu' koja se kodira u svaki novi disk i slijedeći put kad staviš zaštićeni disk u svoj uređaj on je blokiran. Sve ovo vrijedi i za HD-DVD diskove.
Naravno ovo je sve još teorija, tek ostaje vidjeti kako će sve to skupa funkcionirati u praxi...
