IntroductionThis manual describes the over TCP/IP Control Protocol specifications which are applicable when the AW-HE50 HD integrated camera is operated using Ethernet.It consists of three main sections, namely, camera and pan-tilt head control, camera information update notifications and error return.2. Configuration outlineThis manual has the following general configuration.①Camera and pan-tilt head controlIt is possible to control the pan, tilt and white balance adjustments.It is also possible to acquire the gain and other camera information by initiating queries.The various functions are employed for the operations with the camera using HTTP which is the host protocol of TCP.For further details, refer to chapter 3.②Camera information update notificationThe local terminal is notified of the values of the gain and other settings which have been changed at another terminal or other terminals so that it can acquire the camera information.This feature is useful when one camera is controlled by a multiple number of terminals, and when the setting for enabling update notifications to be received has been established, the information which has been changed by other terminals can be acquired.For further details, refer to chapter 4.③Camera information batch acquisitionThe camera information can be acquired in batch form. Since there is no need to query each and every camera information item when this feature is used, the feature is useful when all the camera information is required such as at startup.For further details, refer to chapter 5.④ Error returnAn error — whether ER1, ER2 or ER3 — is returned when an error has been generated by a command in ① above or when the AWB result contains an error.For further details, refer to chapter 6.3. Camera and pan-tilt head controlGiven below are the external interfaces which are used when operating the AW-HE50 camera using Ethernet.This chapter presents the following details.①Pan-tilt head controlInterface which controls the pan-tilt head unit② Camera controlInterface which is related to the lens control of the camera unit and the image adjustments3.1. Pan-tilt head controlGiven below is the command format which is used to control the pan-tilt head when the AW-HE50 camera is operated and which accords with the HTTP1.0 communication specifications. For details on the HTTP messages, refer to <Appendix>.[Command format][Send]http://[IP Address]/cgi-bin/aw_ptz?cmd=[Command]&res=[Type]Where:IP Address······IP address of camera at connection destinationCommand·······Details given in “Command” column in the command tables belowType················Fixed at “1”[Receive]200 OK “Command”Where:Command·······Response value of each command; set in the HTTP message bodyExample: Pan/tilt (Stop)[Send]http://192.168.0.10/cgi-bin/aw_ptz?cmd=#PTS5050&res=1[Receive]200 OK “pTS5050”※In some cases, it may be necessary for “#” to be converted to “%23” by ASCII conversion.http://192.168.0.10/cgi-bin/aw_ptz?cmd=%23PTS5050&res=1Given below is the communication sequence which accords with the command format presented on the previous page.For the communication sequence of the errors generated in response to commands which have been sent, refer to “6. Error return”.[Sequence]“PC1” is the control terminal in the sequence below.Example: Pan/tilt (Stop) controlAW-HE50 IP Address = 192.168.0.10Command = PTS5050The control to stop the pan-tilt operation is exercised from PC1. [200 OK “pTS5050”] is returned as the response from the AW-HE50.The control command and query command are available as the pan-tilt head control commands.Given below is the command sequence.Fig. 3.1-1 Sequence of pan-tilt head controlIt must be borne in mind that communication with the camera is subject to some restrictions.These restrictions are as follows.[Restrictions]1. When using the pan-tilt head control commands, send the commands with a gap of 130 ms betweeneach command. Given below is the sequence.Fig. 3.1-2 Restrictions2. The number of sessions during which the camera can be accessed simultaneously is as follows.a) Maximum number of HTTP sessions: 72b) Number of terminals which can receive update notifications at the same time: 5When the AW-RP50 is connected, it is counted as one unit.3. Keep-Alive cannot be set with HTTP connections.Connect and disconnect are performed each time a command is sent or received.3.1.1. Power ON/OFFThese commands enable the power ON/OFF of the AW-HE50 to be controlled and the current power ON/OFF statuses to be acquired.Table 3.1.1.

网络摄像机传输协议概述
1、传输协议
网络摄像机提供很多基于IP网络的传输协议，以尽可能地保证音视频数据，PTZ控制
数据网络传输质量。实时视频流经过IP网络传输，通过多种协议组合，适应各种复杂的
网络传输环境。
RTP(Realtime Transport Protocol),实时传输协议，其专门针对实时流媒体而设计， RTP
的基本功能是将几个实时数据流复用到一个UDP分组流中，这个UDP流可以被发送给一
台主机（单播模式），也可以被传送给多台目标主机（多播模式）。因为RTP仅仅封装成
常规的UDP，理论上路由器不会对分组有任何特殊对待，但现在高级的路由设备都有针对
RTP协议优化选项。RTP协议的时间戳机制，不仅减少了抖动的影响，而且也允许多个数
据流相互之间的同步，这样可以很方便地基于I/O事件对视频图像进行字幕添加，网络摄
像机往往将音视频编码数据封装成RTP分组。
RTCP(Realtime Transport Control Protocol)实时传输控制协议，其是RTP的姊妹协议，
它处理反馈、同步和用户界面等，但是不传输任何数据。它的主要功能是用来向源端提供
有关延迟、抖动、带宽、拥塞和其它网络特性的反馈信息，编码进程可以充分利用这些信
息。因此当网络状况较好时，可以提高数据速率（从而达到更好的质量），而当网络状况
不好时，它可以减少数据速率。通过连续的反馈信息，编码算法可以持续地作相应的调整，
从而在当前条件下尽可能地提供最佳的质量。
RTSP(Real Time Streaming Protocol)实时流协议，RTSP协议利用推式服务器
(push server)方法，让音视频浏览端，发出一个请求，网络摄像机只是不停地向浏览端推
送封装成RTP分组的音视频编码数据，网络摄像机可以用很小的系统开销实现流媒体传
输。
HTTP(HyperText Transfer Protocol)超文本传输协议，网络摄像机通过HTTP协议提供
Web访问功能，很方便地将音视频数据经过复杂网络传输，但实时音视频支持很不理想。
UDP(User Datagram Protocol)数据报协议，是最基本的网络数据传输协议，利用IP协
议提供网络无连接服务，常用来封装实时性强的网络音视频数据，即使网络传输过程中发
生分组丢失现象，在客户端也不会影响音视频浏览。
TCP(Transmission Control Protocol)传输控制协议，利用IP协议提供面向连接网络服
务，为在不可靠的互联网络上提供一个可靠的端到端字节流而设计。TCP协议往往要在服
务端和客户端经过多次“握手”才能建立连接，因此利用TCP传输实时性较强的音视频流开
销较大，如果网络不稳定，音视频抖动的现象明显。利用其可靠性常用来传输网络摄像机
管理命令，如PTZ，I/O设备控制命令。
2、传输协议组合
网络摄像机往往应用RTSP、RTP、RTCP、HTTP、UDP、TCP协议的不同组合来传输实
时性较强的音视频流。常见的协议组合如下。
RTP+RTSP协议组合，这种协议组合(RTP可以用TCP、UDP协议封装，RTSP用TCP
协议封装)，在正常网络环境里，可以保证客户端浏览实时音视频，厂商往往推荐网络摄
像机采用这种协议组合。一些网络设备也常常支持RTP+RTSP多播模式。
RTP/RTSP协议组合，RTP分组封装成RTSP分组，有些网络防火墙只让RTSP协议分
组通过。但网络摄像机又要以RTP协议提供实时音视频。这种组合方式在没有办法的情况
下增加了网络负载和客户端管理系统的复杂度。
RTP/RTSP/HTTP协议组合，在RTP/RTSP的数据基础上增加了HTTP封装，这种协议
组合主要是为了适应网络防火墙只允许使用HTTP协议的网络环境。虽然网络负载加大，
但网络摄像机可以适应更复杂的互联网环境。
UDP(TCP)协议，一些网络摄像机为了适应国内网络带宽状况不佳的状况，没有利用
RTP+RTSP应用层协议封装音视频数据，对音视频流只采用UDP或TCP传输层协议封装。
这样音视频流就可以利用很小的网络带宽传输流媒体。这种协议组合也可以提供类似
RTP+RTSP高级功能，但对网络路由设备基于RTP+RTSP组合优化特性不能利用。
UDP(TCP)/HTTP协议组合，将音视频流数据封装成HTTP数据分组，然后用UDP(TCP)
协议传输到客户端。这种协议方式可适应复杂的互联网环境，可以穿透大多数网络防火
墙。
各种传输层协议组合保证了音视频和PTZ数据实时传输的可靠性，但网络摄像机内置
的处理器计算能力限制，导致并发访问的用户数量有限。这样往往不能满足并发访问要求
较高的应用环境，网络摄像机往往利用具备多播功能的网络传输设备，响应更多的并发访
问要求。有些网络摄像机客户端软件功能强大，利用数据转发机制，充当可以响应更多并
发访问用户的“虚拟网络摄像机”，这种方式适应于也适应PTZ网络摄像机。对大规模数字
化视频监控网络建设有重要意义。
