[0110] 为使本发明的实施例要解决的技术问题、技术方案和优点更加清楚,下面根据用于远程庭审的数字法庭系统运行时序图进行详细描述: [0110] For technical problem to be solved by embodiments of the present invention, technical solutions and advantages clearer, the following detailed description of the operating timing chart of a system for remote digital court the trial:

[0111] 开始远程庭审序列图如图6所示:在图6的时序图中可以看出当启动远程庭审时, 各个模块信号间的流向说明如下。 [0111] Remote Start trial sequence chart shown in Figure 6: In the timing chart of FIG. 6 can be seen when the remote trial starts, the flow of signals between the various modules described below.

[0112] COS作为远程庭审触发源,当点击启动远程庭审时,COS将会通过以太网发送启动命令给本地的RMS ;[0113] RMS收到命令后立即发送启动本地SMS直播,同时还会发送一启动命令给远程的RMS,当远程的RMS启收到命令后,将会立即发送命令给远程的SMS,通知远程的SMS启动直播; [0112] COS trial as a remote trigger source, when you click the remote start the trial, COS will start sending commands via Ethernet to the local RMS; [0113] RMS after receiving the command to start sending local SMS broadcast immediately, while also sending a start command to the remote RMS, RMS remote start when the command is received, the command will be sent immediately to a remote SMS, SMS notification remote start live;

[0114] 远程SMS启动直播后向远程RMS发送开启成功命令,并由远程RMS转发本地RMS ; 本地SMS启动直播后也会向本地RMS发送开启成功命令 [0114] After the remote start live SMS sent to a remote RMS successful open command by remote local RMS RMS forward; after local SMS broadcast will start sending commands to successfully open local RMS

[0115] 当本地的RMS收到远程的RMS及本地的SMS开启成功命令后,将会发送连接音视频源的命令给到远程的RMS及本地的SMS,当远程的RMS收到连接音视频源命令后,会将命令给到远程的SMS ; [0115] When the local RMS RMS receive remote and local SMS command to open successfully, it will send a command to connect audio and video source, RMS and local SMS to the remote, and when the RMS remote connection to receive audio and video source command, will give the command to the remote SMS;

[0116] 远程SMS连接音视频源成功后向远程RMS发送连接成功命令,并由远程RMS转发给本地RMS ;本地SMS连接音视频源成功后也会向本地RMS发送连接成功命令; [0116] Remote source audio and video connection SMS successfully sent a successful connection to the remote command RMS, forwarded by the remote to the local RMS RMS; audio and video sources connected to the local SMS will be sent after a successful connection is successful command to the local RMS;

[0117] 当本地的RMS收到远程的RMS及本地的SMS连接成功命令后,会向COS返回一条开启远程庭审成功的确认信息。 [0117] When the local RMS and the RMS receive local remote SMS commands connection is successful, it will return to the COS to open a remote confirmation of successful trial. 至此一个完整的开启远程庭审流程完成。 At this point a complete remote open trial process is complete.

[0118] 远程庭审音视频动态切换序列图如图7所示:在图7中可以看出,当启动远程庭审后,用于切换远程信号源的信号流向图。 [0118] Trial remote audio and video dynamic switching sequence shown in Figure 7: As can be seen in FIG. 7, when the remote start trial, for switching the signal flow diagram of a remote signal source.

[0119] COS作为远程庭审信号源连接触发源,当点击启动连接远程庭审到本地显示时, COS将会通过以太网发送连接远程音视频源命令给本地的RMS ; When [0119] COS trial as a remote signal source trigger source, click initiates a connection to the remote local display trial, COS will send audio and video source connected to the remote command of the RMS to the local Ethernet;

[0120] 本地RMS收到连接远程音视频源命令后,立即将本地的音视频源停止录制,随之会将当前的所有音视频流文件进行分割封装成一个完整的可以供播放的音视频流文件后, 并且开启远程音视频源的录制,并将本地SMS中直播模块中的直播音视频源更改为远程的直播音视频源,并且本地SMS通知启动DVC的解码模块,解码输出的远程图像和音频供显示设备和功放设备使用; After the [0120] RMS receive local audio and video source connected to a remote command, immediately stop local source audio and video recording, along with all current video and audio will stream file is divided into a complete package can be used for playing audio and video streams after the file and open source audio and video recording remote and local SMS in live audio and live video source module is changed to a live audio and video source remote, and local SMS notification enable remote DVC image decoding module, decoding and output amplifiers for audio equipment and the display device;

[0121] 本地RMS在以下几个流程都处理完后,会发送连接远程音视频源命令给远程RMS, 远程RMS在收到命令后将直播URL切换到远程的音视频源,将通知远程的SMS启动解码,这样远程就可以看见本地音视频源的信号了。 [0121] RMS local in the following processes are dealt with, it will connect the remote to send commands to the remote audio and video source RMS, RMS remote URL after receiving the command to switch to the live remote audio and video sources, will inform the remote SMS start decoding, so remote you can see the signal of the local audio and video sources.

[0122] 当COS点击停止连接音视频源时,COS将会通过以太网发送停止连接远程音视频源命令给本地的RMS ; [0122] When the COS Click Stop connected audio and video sources, COS will stop sending via Ethernet to connect to remote audio and video source to the local command of RMS;

[0123] RMS收到命令后立即将远程的音视频源停止录制,随之会将当前的所有文件进行分割封装成一个完整的可供播放的音视频流文件后,随之开启本地音视频源的录制,并将直播模块中的直播源更改为本地的直播源,并通知SMS停止解码模块,远程图像在本地的显示器上将消失; After the [0123] RMS command immediately after receiving the remote audio and video source to stop recording, along with all current files will split the package into a complete audio and video streaming files available for playback, audio and video sources will enable local recording, broadcast and live in the module to change the source for the local broadcast source, and SMS notification to stop decoding module, remote image disappears on the local display;

[0124] 本地RMS在以上几个流程都处理完后,会发送断开连接远程音视频源命令给远程RMS,远程RMS在收到命令后将直播的URL切换到本地的音视频源,将通知远程的SMS停止解码,这样远程就可以看不见本地音视频源的信号了。 [0124] In the above local RMS several processes have been dealt, the remote sends a disconnect command to the remote audio and video source RMS, RMS remote command is received after the URL of the live audio and video switching to the local source, the notification SMS remote stop decoding, so remote you can not see the signal of the local audio and video sources.

[0125] 当本地的RMS处理完以上流程后,会向COS返回一条断开成功的确认信息。 [0125] When the local RMS processed above flow, the COS will return a confirmation of successful disconnection. 至此一个完整的断开远程庭审流程完成。 At this point a complete disconnect remote trial process is complete.
