HDCP文档
HDCP1. 什么是HDCP？HDCP（High-bandwidth Digital Content Protection）是一种用于保护音视频内容传输的加密技术。
它使用了一套加密协议，可以在高清电视、投影机、蓝光播放器等设备之间传输受保护的内容，并防止未经授权的内容拷贝和传播。
2. HDCP的工作原理HDCP的工作原理如下：1.建立连接：当两个支持HDCP的设备之间建立连接时，它们会进行一系列的握手协议，以确认彼此支持HDCP。
2.认证：一旦连接建立，源设备会向显示设备发送认证请求。
显示设备需以相应的认证方式回复，证明其合法性。
3.协商密钥：一旦双方通过认证，源设备会生成一个随机数，并将其加密后发送给显示设备。
双方使用这个随机数来计算出一个共享的密钥。
4.加密传输：通过共享的密钥，源设备将内容进行加密，传输到显示设备。
显示设备需要解密接收到的内容，才能正确显示。
3. HDCP的版本HDCP的协议版本有多个，每个版本都有自己的优化和改进。
以下是一些常见的HDCP版本：•HDCP 1.x：这是最早的HDCP版本，它使用40位的RSA密钥进行加密和认证。
•HDCP 2.x：这是目前使用最广泛的HDCP版本。
它使用128位的RSA密钥进行加密和认证，并提供了更强的安全性。
•HDCP 3.x：这是最新的HDCP版本，于2018年发布。
它进一步增强了安全性，并支持更高的带宽和更高的分辨率。
4. HDCP的应用HDCP广泛应用于各种视频传输设备和标准，包括：•HDMI：HDCP是HDMI（High Definition Multimedia Interface）标准必备的加密技术。
通过HDCP，HDMI可以传输高清、多通道音频和视频信号，并保证内容的安全性。
•DisplayPort：HDCP也被广泛应用于DisplayPort接口。
DisplayPort 是一种数字显示接口标准，用于连接电脑、显示器和其他外部设备。
HDCP协议讲解
HDCP协议讲解HDCP（High-bandwidth Digital Content Protection）是一种用于保护数字内容传输的加密协议，主要用于保护高清视频和音频数据的传输。
它是由英特尔（Intel）公司推出的一项技术。
HDCP的目的是防止未经授权的拷贝和传输数字内容，以保护版权。
通过使用HDCP协议，数字内容在信号源和显示设备之间进行加密和解密，防止未经授权的复制和传输。
它可以阻止数字内容在高清显示设备上以非法的方式播放。
HDCP协议的主要原理是使用一对公钥和私钥来进行加密和解密。
在信号源和显示设备之间建立一个私密的通信链路。
信号源（如蓝光播放器、游戏机等）将数字内容分组为小块，然后用自己的私钥对每个小块进行加密。
加密后的数据通过HDMI、DisplayPort等接口传输到显示设备。
显示设备使用预先共享的公钥对加密数据进行解密和恢复。
这样，只有信号源和显示设备之间共享的公钥才能解密加密数据。
HDCP协议的加密和解密过程相对复杂，需要多个步骤。
首先，信号源和显示设备之间进行握手，交换和验证加密密钥。
然后，信号源将数字内容分组为小块，并使用自己的私钥对每个小块进行加密。
加密的数据通过接口传输到显示设备，并使用预先共享的公钥进行解密和恢复。
在整个过程中，通过加密和解密的数据还要进行一些校验，以确保数据的完整性和安全性。
HDCP协议的核心是授权和认证机制。
在信号源和显示设备之间握手和交换密钥时，会进行授权和认证过程。
信号源和显示设备必须验证对方的身份和授权信息，以确保只有合法的设备之间才能建立通信链路。
如果设备未经授权，握手过程将失败，无法建立HDCP加密通道。
这就防止了未经授权的设备连接到显示设备或未经授权的复制和传输数字内容。
然而，HDCP协议也存在一些问题和争议。
首先，HDCP协议的加密和解密过程要求信号源和显示设备具有HDCP认证芯片，这增加了设备成本和复杂性。
其次，HDCP协议的握手和认证过程需要一定时间，可能会导致延迟和不稳定性。

WIFI-Direct（Wifi直连）、AirPlay、DLAN、Miracast功能介绍
WIFI-Direct（Wifi直连）、AirPlay、DLAN、Miracast功能介绍不知道⼤家对⽆线同屏技术有多少了解，当这种技术普及的时候，我想我们的⼯作与⽣活⼜会⽅便很多吧！下⾯是⽬前三种主流同屏技术的介绍：⽬前这种将终端信号经由WiFi传输到电视、电视盒的技术有三种：DLNA、AirPlay、Miracast。
⼀、AirPlayAirPlay 是苹果开发的⼀种⽆线技术，可以通过WiFi将iPhone 、iPad、iPodtouch 等iOS 设备上的包括图⽚、⾳频、视频通过⽆线的⽅式传输到⽀持AirPlay 设备。
售价99美元的Apple TV就具备这样的功能，现在⼀些传统的家庭影院和HIFI如马兰⼠和天龙的新品功放和⽹络播放器已经⽀持AirPlay功能。
AirPlay具备与DLNA所没有的镜像功能，这⼀功能叫AirPlay镜像，可将iPhone 或iPad 上的画⾯⽆线传输到电视上，也就是说你设备显⽰的是什么，电视屏幕显⽰就就是什么，⽽不仅限于图⽚和视频。
你可以拿着iPad 来当做⽅向盘，然后看着⼤屏玩游戏。
另外AirPlay镜像最⽜地⽅是它可以实现双屏游戏，让你的游戏有更多的交互。
⽐如，电视⾥显⽰的是游戏画⾯，⽽iPad上显⽰的是⽐赛的路线图。
⽬前，苹果的AirPlay更多的只适⽤于认证过的苹果设备，⽬前⽀持这⼀技术的主要是苹果⾃⼰的设备包括了iPad、iPhone、Apple TV等，此外还有⼀些苹果授权的合作伙伴的设备，如向Pioneer和Sony提供技术授权的⾳响。
⼆、DLNADNLA，Digital Living Network Alliance，是索尼、英特尔、微软等发起的⼀套 PC、移动设备、消费电器之间互联互通的协议。
它们的宗旨是“随时随地享受⾳乐、照⽚和视频”。
DLNA只能传输媒体资料数据（即：⾳乐、照⽚、视频、链接信息），不能传输其他类⽂件，也不能实现镜像（同屏显⽰）。

win10miracast功能流程
win10miracast功能流程
要使用Win10的Miracast功能，您需要确保以下条件与操作：
1. 硬件支持：您的电脑和显示设备必须支持Miracast。
大部分
较新的Windows 10系统都支持该功能，但您需要检查并确保
您的显示设备也支持Miracast。
2. Wi-Fi连接：您的电脑和显示设备需要连接到同一个Wi-Fi
网络。
3. 打开设置：点击Windows 10的开始菜单，在开始菜单中找
到设置（齿轮图标）并点击打开。
4. 进入显示设置：在设置窗口中，找到"系统"并点击打开。
在
系统设置窗口中，选择左侧的"显示"选项。
5. 找到Miracast选项：在显示设置窗口中，向下滚动并找到"
连接到无线显示"选项。
点击该选项以打开Miracast设置。
6. 打开Miracast：在"连接到无线显示"窗口中，找到"启用无线显示"选项并将其切换为打开状态。
7. 连接显示设备：启用Miracast后，您的电脑将开始搜索支持Miracast的显示设备。
在列表中选择您想要连接的显示设备。
8. 等待连接成功：电脑和显示设备将尝试建立连接。
一旦连接成功，您的电脑的屏幕将在显示设备上显示。
注意：以上流程可能会因您的电脑型号和Windows 10版本而有所不同。
流程中的某些选项名称和位置可能会有所差异，但一般来说，找到"连接到无线显示"选项并启用Miracast就可以使用该功能了。

hdc常用命令 -回复
hdc常用命令-回复HDC（华为开发者工具链）是华为公司自主研发的一套用于开发华为设备的开发者工具链。
它提供了一系列的命令，可以帮助开发者进行设备的调试、编译和部署等工作。
本文将介绍HDC常用命令的使用方法，并逐步解析其功能和应用场景。
1. hdc config该命令用于配置HDC环境，包括设置HDC的路径、设备的连接方式等。
在使用HDC之前，首先需要将HDC配置为适合你的开发环境。
例如，可以使用"set HDC_HOME=D:\hdc"命令将HDC的安装路径设置为D盘的hdc文件夹。
2. hdc start当配置完成后，可以使用hdc start命令启动HDC服务。
该命令会检测是否有设备连接到计算机，并启动与设备之间的通信。
在设备连接成功后，可以使用其他HDC命令对设备进行操作。
3. hdc devices使用hdc devices命令可以查看当前已连接的设备列表。
该命令会显示设备的序列号、型号以及连接状态等信息。
可以通过该命令确认设备是否成功连接到计算机。
4. hdc runhdc run命令用于在设备上运行应用程序或命令。
可以使用该命令将编译好的应用程序安装到设备上，并启动应用程序。
例如，可以使用"hdc run -p com.example.myapp"命令安装并启动包名为com.example.myapp 的应用程序。
5. hdc push使用hdc push命令可以将文件或文件夹从计算机复制到设备上。
例如，可以使用"hdc push D:\myapp.apk /sdcard/"命令将D盘下的myapp.apk文件复制到设备的sdcard目录下。
6. hdc pull相反，hdc pull命令可以将文件或文件夹从设备复制到计算机上。
例如，可以使用"hdc pull /sdcard/myapp.apk D:\"命令将设备上的/sdcard/myapp.apk文件复制到计算机的D盘根目录下。

A common use case is a Miracast® user displaying an HDCP-protected movie from their mobile phone or tablet to a television.This document describes an observed interoperability issue between some Miracast Source implementations with an HDCP 2.0/2.1 stack/certificate and some Miracast Sink implementations with an HDCP 2.2 stack/certificate where the content does not render correctly due to an authentication issue. If a Source fails authentication with a Sink, the user may experience errors such as:∙The Source and Sink may provide no information to the user, and it appears to the user that the connection has “failed”∙The Source may provide an audio-only connection to the Sink∙The Source may show a blank screen to the user with no other information∙The Source or Sink may indicate some kind of “Content Protection” error ProblemSome Source implementations incorrectly assumed that Reserved bits (3087:3072) in the HDCP Receiver Public Key Certificate of [1] must always be zero (0x0000) and rely on that assumption as part of signature validation. HDCP 2.2 updated the certificate format and uses 4 of the 16 previously reserved bits (3087:3084) as the Protocol Descriptor [2], The Protocol Descriptor value can be 0x0 or 0x1. If the Source fails signature validation for Sinks supplying a certificate as part of AKE_RX_Info message of [1] with the bits set to anything other than 0x0, then it will not authenticate Sinks using HDCP 2.2 certificates, resulting in broken forward compatibility.Similar problems may occur if an HDCP capable Sink inadequately handles the received Reserved bits within HDCP AKE messages of [2] from a Source. RecommendationWi-Fi Alliance® recommends that all HDCP-capable Miracast device vendors check their devices for implementations that inadequately handle the received Reserved bits defined in the HDCP IIA 2.x specification and update any affected devices to correct this error. All 16 bits (3087:3072) shall be ignored in HDCP 2.0/2.1 implementations and the specific bits of the Protocol Descriptor shall be checked in HDCP 2.2 implementations (3087:3084).Suggestions on providing feedback to a user after an authentication error are described in the “Best Practices Document for Wi-Fi CERTIFIED Miracast™ Devices” [3].References[1] “High-bandwidth Digital Content Protection System, Interface Independent Adaptation” Revision 2.0”, 23 October, 2008, Digital Content Protection LLC[2] “High-bandwidth Digital Content Protection System, Interface Independent Adaptation” Revision 2.2”, 16 October, 2012, Digital Content Protection LLC[3] “Best Practices Document for Wi-Fi CERTIFIED Miracast™ Devices”, September 2014, Wi-Fi Alliance。
