图1为本申请实施例提供的一种监控视频的传输场景示意图,所述场景包括监控端、视频图像采集端,其中:FIG. 1 is a schematic diagram of a transmission scenario of a surveillance video according to an embodiment of the present disclosure, where the scenario includes a monitoring terminal and a video image collection terminal, where:
所述监控端可以为服务器监控中心、台式电脑终端或移动终端,所述监控端可以通过多个码流通道接收多个视频图像采集端的视频图像,并且可以通过图像阵列的方式,同时显示多个视频图像,从而方便监控端的工作人员对多个场景同时进行监控。The monitoring terminal may be a server monitoring center, a desktop computer terminal or a mobile terminal, and the monitoring terminal may receive video images of multiple video image collecting ends through multiple code stream channels, and may simultaneously display multiple images through an image array. The video image is convenient for the monitoring staff to monitor multiple scenes at the same time.
所述视频图像采集端可以包括摄像机、处理器、存储器和通信电路,所述摄像机可以用于采集高清的视频图像,通过所述处理器可以对高清的视频图像进行码率转换,得到两种不同码率的视频图像。比如可以得到一路720P的高清码流,对应的码率为4Mbps左右,另一路视频图像的码率可以为700Kbps,将得到的不同码率的视频图像分别通过存储器进行存储。可以通过通信电路,结合视频图像选择指令,选择其中一路或者两路视频图像进行传送。The video image collecting end may include a camera, a processor, a memory, and a communication circuit, and the camera may be used to capture a high-definition video image, and the processor may perform rate conversion on the high-definition video image to obtain two different Rate video image.

One or two video images can be selected for transmission through a communication circuit in combination with a video image selection command.
图2为本申请实施例提供的一种监控视频的传输方法的实现流程示意图,详述如下:FIG. 2 is a schematic flowchart of an implementation process of a monitoring video transmission method according to an embodiment of the present disclosure, which is as follows:
在步骤S201中,通过摄像机获取视频图像,将所获取的视频图像转换为第一码率的视频图像和第二码率的视频图像进行存储,其中第一码率小于第二码率;In step S201, the video image is acquired by the camera, and the acquired video image is converted into a video image of a first code rate and a video image of a second code rate, where the first code rate is less than the second code rate;
具体的,本申请所述的摄像机,可以包括高清摄像机,所获取的视频图像的清晰度和码率较高,传输所述视频图像所需要较多的网络带宽。当然,所述摄像机也可以包括麦克风对音频数据进行采集,所采集的音频数据也可以为高保真的音频等。Specifically, the camera of the present application may include a high-definition camera, and the obtained video image has higher definition and code rate, and more network bandwidth is required for transmitting the video image. Of course, the camera may also include a microphone to collect audio data, and the collected audio data may also be high-fidelity audio.
将所述摄像机获取的视频图像转换为第一码率的视频图像和第二码率的视频图像时,可以包括以下情形:When the video image acquired by the camera is converted into a video image of a first code rate and a video image of a second code rate, the following situations may be included:
1、摄像机所拍摄的视频图像为第二码率的视频图像,第一码率的视频图像为根据所述第二码率的视频图像所转换得到。其中,第二码率大于第一码率,在第二码率的视频图像中包括更多的图像细节,可以通过牺牲图像细节的方式,将第二码率的视频图像转换为第一码率的视频图像,虽然第一码率的视频图像损失了较多的细节,但是仍然包括视频图像中的主要内容,并且在图像阵列播放所述第一码率的视频图像和第二码率的视频图像时,用户一般不会能感觉到明显的区别。1. The video image captured by the camera is a video image of a second code rate, and the video image of the first code rate is converted according to the video image of the second code rate. Wherein, the second code rate is greater than the first code rate, and more image details are included in the video image of the second code rate, and the video image of the second bit rate can be converted to the first code rate by sacrificing image details. Video image, although the video image of the first bit rate loses more detail, but still includes the main content in the video image, and plays the video image of the first bit rate and the video of the second bit rate in the image array. When the image is used, the user generally cannot feel the obvious difference.
2、摄像机所拍摄的视频图像为原始码率的视频图像,对所述原始码率的视频图像进行码率转换,得到第一码率的视频图像和第二码率的视频图像,并且第一码率小于第二码率,第二码率小于原始码率。所述第二码率可以根据视频图像采集端的通信电路的传输速度,作相适应的调整,比如通信电路为3G通信电路或者4G通信电路时,所对应的传输速度也不相同。2. The video image captured by the camera is a video image of the original code rate, and the video image of the original code rate is subjected to rate conversion to obtain a video image of the first code rate and a video image of the second code rate, and the first The code rate is less than the second code rate, and the second code rate is less than the original code rate. The second code rate can be adjusted according to the transmission speed of the communication circuit of the video image collecting end. For example, when the communication circuit is a 3G communication circuit or a 4G communication circuit, the corresponding transmission speed is also different.
在步骤S202中,当没有接收到视频关注指令时,实时将第一码率的视频图像传送至监控端;In step S202, when the video attention instruction is not received, the video image of the first code rate is transmitted to the monitoring end in real time;
其中,所述视频关注指令可以由监控端发送,当所述监控端为多个通道的视频同时在同一个显示屏显示时,所述关注指令可以为用户输入的对其中某个通道的视频画面选择指令,或者用户对某个通道的视频画面的放大指令。The video attention instruction may be sent by the monitoring end. When the monitoring end is a video of multiple channels simultaneously displayed on the same display screen, the attention instruction may be a video screen input by the user to one of the channels. Select the command, or the user's zoom instruction for the video screen of a channel.
当然,所述视频关注指令不局限于上述两种,还可以通过标记的方式,或者通过菜单选项设置的方式,生成用户对视频的关注指令。Of course, the video attention instruction is not limited to the above two types, and the user's attention instruction to the video may be generated by means of marking or by setting a menu option.
在视频图像采集端没有接收到所述关注指令时,则可以将第一码率的视频图像传送至监控端,由于第一码率的视频图像占用的网络资源少,节省传输视频图像所需要的流量,可以在监控端实时播放,并且一般处于小窗口播放状态时,不能明显的感觉到所播放的第一码率的视频图像与第二码率的视频图像的差异。When the video image acquisition end does not receive the attention instruction, the video image of the first code rate can be transmitted to the monitoring end, and the video image occupied by the first code rate occupies less network resources, saving the need for transmitting the video image. The traffic can be played in real time on the monitoring end, and when it is in the small window playing state, the difference between the played video image of the first bit rate and the video image of the second bit rate cannot be obviously perceived.
在步骤S203中,当接收到视频关注指令时,将第二码率的视频图像传送至监控端。In step S203, when the video attention instruction is received, the video image of the second code rate is transmitted to the monitoring terminal.
当接收到视频关注指令时,则将第二码率的视频图像传送至监控端,从而使得监控端能够根据分辨率较高的第二码率的视频图像,对图像的细节进行查看和分析。When the video attention instruction is received, the video image of the second bit rate is transmitted to the monitoring end, so that the monitoring end can view and analyze the details of the image according to the video image of the second bit rate with higher resolution.
当然,当监控端发送视频图像关注的指令后,还可以取消对视频图像的关注,并相应的发送视频关注取消指令至监控端,所述监控端根据所述关注取消指令,重新选择第一码率的视频图像进行传输。Certainly, after the monitoring terminal sends the instruction of the video image, the attention of the video image may be cancelled, and the video cancellation cancellation instruction is sent to the monitoring end, and the monitoring terminal reselects the first code according to the attention cancellation instruction. The rate of video images is transmitted.
所述视频关注取消指令可以根据放大的视频图像缩小时生成。The video attention cancellation instruction may be generated when the enlarged video image is reduced.
本申请通过将摄像机获取的视频图像进行码率转换,得到两个不同码率的视频图像,并且在接收到视频关注指令时,向监控端传输较高码率的视频图像,在没有接收到视频关注指令时,则传送较低码率的视频图像,从而使得系统能够通过转换得到的较低码率的视频图像进行传输,可以有效的节约网络资源,降低流量资费的同时,还能实时的察看视频图像,并且可以获取所关注的视频图像的高码率画面,方便监控人员对细节图像的获取。The present invention obtains video images of two different code rates by performing rate conversion on the video images acquired by the camera, and transmits a video image of a higher bit rate to the monitoring end when receiving the video attention instruction, and does not receive the video. When attention is paid to the instruction, the video image of the lower bit rate is transmitted, so that the system can transmit the video image of the lower bit rate obtained by the conversion, which can effectively save network resources, reduce the flow rate, and can also observe in real time. The video image and the high bit rate picture of the video image of interest can be obtained, which is convenient for the monitoring personnel to acquire the detailed image.
