HDCP是针对数字视频输出接口的
和解锁复制蓝光没有关系
HDCP失效后,用户能做的也就是搞一张捕捉卡从HDMI端口做视频捕获
这个数据量,我就不说啥了
而且同样也可以说啥cable的payperview等等都可以所谓"自由解锁复制"
实际中,写这篇文章的人连啥是HDCP都没有搞清楚
保护蓝光的是AACS,BD+
这个这篇文章中的HDCP换成AACS的master key泄露,那么差不多就对了

Intel今天证实,日前在互联网上泄露的所谓HDCP主密钥的确是真实有效的,这也就意
味着数百万蓝
光光盘、播放器等设备的保护盾已经在瞬间土崩瓦解,所有蓝光光盘都可以自由解锁、
复制。
Intel官方发言人Tom Waldrop回应说,经过两天的调查后,他们已经就此事通知了数百
家合作伙
伴、授权客户。他说:“我们已经测试了网上公布的材料。它确实能生成密钥……这就
意味着它能绕过
(保护)代码。”
至于实际产生的后果,Waldrop认为最可能的是有黑客制作一颗计算机芯片,在其中嵌
入泄露的这个
主密钥,用来解码蓝光光盘,而软件解码器的可能性虽然不大,“但我也不会说绝对不
会有”。
Waldrop还指出,Intel仍然相信HDCP技术是一种完全合情合理的保护手段,不过一旦出
现盗版内
容,影视产业可能不得不拿起法律武器。
HDCP全称High Definition Content Protection,意思是高清内容保护,由Intel开发
、其
子公司Digital Content Protection LLP负责管理,主要用来在电影、电视等数据通过
DVI、
HDMI传输的时候进行加密

基本上
A卡从HD HD2000系列起支持Dual-link HDCP Capable
N卡从9000系列起支持Dual-link HDCP Capable
外加N卡的全部8600GTS和部分8500/8600GT也支持

sly 的anydvd HD想办法的模拟出了蓝光光驱的证书,然后从powerdvd/TMT3的播放软件
这里搞到了AACS的子key,具体过程我是外行
但是简单的说,就是AACS master key生成 的解码的key,虽然不断被更新和吊销
但是由于某些漏洞的存在,新的key总有办法被获取
至于BD+,这个他们似乎是搞定了BD+的虚拟机
由于整个过程是动态的,AACS的子key也不断在更新,BD+也是
所以sly 的anydvd HD也需要不断的更新,适应形势变化
bluray rip和HDCP是毫无关系的,你如果知道HDCP保护的是啥就明白了
如果哪天AACS的master key被泄露出来了,这个么....

来自主题: Hardware版 - HDMI1.4 怎么支持HDCP?
我买了一个号称4K的长虹电视,结果它的HDMI是1.4版本的。我用ROKU4时提示不能用4K
,因为端口不支持HDCP 2.2。我网上查了一下好像HDMI 1.4也应该支持HDCP (是不是2
.2就不知道了)。
请问有没有什么解决方案?能不能买一个Adapter之类的东西呢?
PS:这个电视有一个HDMI端口旁边写着MHL,因为这是所谓ROKU ready TV。不知道这个
MHL能不能起到一些作用。。。

你是说对盗版的影响?对cable,卫星电视的影响更大一些。说白了这个HDCP就是流向
屏幕的数据加密,这个解密后显示
是有屏幕内嵌的芯片做的。以前盗版基本上是analog attach, 就是出于历史原因,很
多播放器都有analog output, 这个是
不加密的高清。
蓝光在美国依然不是主流,很可能永远不会象DVD/VHS一样普及,所以可能对cable, 卫
星电视的影响更大一些,用户可以
简单的截取流向屏幕的数据,随便盗版ppv.

今天刚买了个ROKU 3, 只要我关电视,然后重新想看,就紫屏出现"HDCP unauthorised.
Content disabled"
在网上搜到有人说重新插拔HDMI线就可以了,我该拔的都拔了,该重启就重启了,搞伤了
都.
还有网上说换HDMI线,这个我也换了,也不管用
有没有人遇到同样的情况啊

谢谢解答.
我确定线肯定没问题,家里有一根,然后买的ROKU有自带的一根,我都试了,不管用.
然后你说的换接口,电视有3个HDMI接口,我也试了也不管用.
今天早上又去店里换了个ROKU, 拿回来还是同样的问题.
不过我发现每次打开电视机的时候,打开的时候是紫屏"HDCP unauthorised. Content
disabled".然后我用电视遥控器切换到另一个电视台,然后再切换到我ROKU连到电视上
的那个HDMI台,紫屏消失,就又能看了.你分析这可能是什么问题呢.
这样凑合也能用,就是每次要切换一下.

听起来像是电视方面的问题了,你是什么牌子和型号?用电视的牌子加上‘HDCP
unauthorised. Content
disabled’关键字到google上查看一下,看看别人遇到没有。
另外就是拿着线和盒子到朋友家测试一下。

来自主题: Apple版 - Apple TV 2 说hdcp错误
从买回来开始apple tv2 就经常说 This content requires HDCP for playback,重启
apple tv也没用 HDMIcable也重新插了。我们的三星电视去年才买的,HDMI cable也是
从apple店买的。有人也有这个问题吗?

入了一个3008wfp。
看了一些review,貌似如果用它来看bluray,听说仅仅一个dvi支持hdcp不行,得接两
个dvi口而且
得两个口都支持
这样的话,还得重新买显卡。如果显卡只有一个hdmi,一个dvi的话,把hdmi和dvi接过
去可不可以?
hdmi是dvi的超集是吧?
谢谢!

应该是
Support HDCP over Dual-link DVI
而不是Two DVIs
Dual-link DVI是“一”个DVI接口,而不是两个。
你用的是什么显卡?

嗯,如果不支持就只能升级显卡。newegg上面说是支持dual link dvi,
我看了接口,也是dual lnk dvi的接口
但是这个不一定意味着支持hdcp over dual link dvi是把
