+
+# 3 方案介绍
+七牛实时音视频云支持低延时音视频通话，提供灵活丰富的接口，方便进行二次开发。该系统主要包括服务端和客户端两个部分，其中，服务端主要提供了房间管理、权限验证、信令和媒体数据转发等功能，客户端则提供了媒体数据的采集、编解码、传输、渲染等功能。
+
+### 3.1 系统框图
+![](http://docs.qnsdk.com/qnrtc-overview-architecture.png)
+
+整个系统的架构如上图所示，主要分为三个部分：
+
+- <b> 客户端 SDK </b>
+
+  主要负责客户端的音视频采集、渲染、滤镜处理、编解码、传输等工作，客户可以快速集成到自己 App 中，让自己的应用具备音视频通话的能力
+
+- <b> 服务端 REST API 和 SDK </b>
+
+  主要提供房间管理、状态回调等基本的业务功能，另外还提供鉴黄鉴暴、质量分析等配套功能
+
+- <b> 服务器 </b>
+
+  主要负责信令交互、音视频传输、代理加速等工作，保证音视频互动延时低，可用性高
+  
+### 3.2 交互流程
+
+![](http://docs.qnsdk.com/qnrtc-interactive.png)
+
+实时通话交互流程如上图所示，因此，App 服务端需要开发的工作如下：
+
+- 为用户创建通话房间，并将通话房间和对应主播的 Id 关联起来
+- 计算加入房间的 roomToken 并提供给 App，该 roomToken 是结合 userId、roomName 等信息使用七牛的 AccessKey 和 SecretKey 按照一定的规则生成
+- 提供通话的业务逻辑，如：通话请求/应答业务逻辑、服务端房间管理和踢人等
+
+关于 roomToken 的计算方法请查阅[《七牛实时音视频云服务端 API 接口规范》](https://developer.qiniu.com/rtc/8805/server-overview)，另外，我们也提供了多种开发语言的 SDK  [服务端开发手册及 SDK 下载](https://developer.qiniu.com/rtc/8812/serversdk)。
+
+### 3.3 房间管理
+关于音视频通话房间的 API 主要分为两个部分，一部分在客户端，另一部分在服务端。在客户端 SDK 中，只有加入/离开连麦房间的接口。我们把创建/销毁连麦房间的功能放到了服务端，由 App Server 向七牛的服务器发送请求来完成。关于服务端 API 的详细内容，请查阅[《七牛实时音视频云服务端 API 接口规范》](https://developer.qiniu.com/rtc/8805/server-overview)。
+
+# 4 方案优势
+- 实时互动对网络的稳定性和连通性要求非常苛刻，所以必须购买数据中心建设基础网络。而使用七牛的实时音视频云服务，不需要投入大量资金做传输网络的基础建设，按量计费灵活方便。
+- 经验丰富的音视频团队提供稳定、易用的客户端 SDK，保证了客户端应用开发的效率和可用性。
+- 完整的音视频产品线，使用七牛的实时音视频云服务的同时可以无缝接入七牛其他的所有服务，例如短视频、直播、存储、大数据分析等服务。
+
+# 5 应用场景
+
+## 5.1 主播连麦
+
+- 支持主播之间连麦一起直播，带来与传统单向直播不一样的体验
+- 自带美颜滤镜，第三方美颜贴纸、人脸识别，让直播过程更有趣
+- 48KHz 采样率、全频带编解码以及对音乐场景的特殊优化保证观众可以听到最优质的声音
+
+## 5.2 视频会议
+
+- 小范围实时音视频互动，提供多种视频通话布局模板，更提供自定义布局方式，保证会议发言者互相之间的实时性，提升普通观众的观看体验
+- 提供七牛云自有的直播分发服务，可实现 HLS、RTMP、HTTP 等多种直播分发形式，支持更多人通过拉取直播流收看会议内容，适合大型的企业在线会议
+- 支持动态邀人，踢人、禁音，禁视会议权限分级控制
+- 客户可以利用七牛实时音视频云轻松做出一款类似 WebEx 的应用
+
+## 5.3 一对一社交
