为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本发明一部分实施例，而非全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1，图1为本发明实施例提供的一种视频编码系统的结构示意图。
本发明提供的一种视频编码系统，包括有源以太网POE交换机和与所述POE交换机线缆连接的至少一个网际互连协议IP视频编码器；
所述IP视频编码器包括数据采集端口、数据处理中心、电源模块、以太网接口和光纤接口；
所述数据采集端口与所述数据处理中心通信连接，所述数据处理中心 用于对所述数据采集端口所采集的信源数据执行数据转换操作，生成以太网数据；
所述光纤接口和所述以太网接口分别与所述数据处理中心通信连接，所述以太网接口和所述光纤接口用于输出所述以太网数据；
所述以太网接口和所述光纤接口分别与所述POE交换机通过线缆连接，所述以太网接口还用于获取所述POE交换机所提供的初始电压；
所述电源模块和所述以太网接口连接，所述电源模块用于将所述初始电压调整为所述IP视频编码器的额定电压。
为了能够扩大IP视频编码器布线范围，提高使用灵活性，最为重要的一点就是如何解决IP视频编码器的供电线与联网线的问题。而在本发明实施例中，通过POE交换机为多个IP视频编码器提供电源，通过多个IP视频编码器中的电源模块对所述POE交换机提供电源电压进行滤波整流，将其电压调整为适用于IP视频编码器的电压。
有源以太网(Power Over Ethernet，POE)指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下，在为一些基于IP的终端(如IP电话机、无线局域网接入点AP、网络摄像机等)传输数据信号的同时，还能为此类设备提供直流供电的技术。
其中，信源与IP视频编码器之间通过HDMI线缆、USB线缆和音频线缆连接。
在具体实现中，IP视频编码器通常是对采集的视频数据进行环出显示，主要用于检测采集的信号是否正常和能否本地显示。因此可以通过所述数据采集端口采集到信源数据并传输到数据处理中心后，由所述数据处理中心对所述信源数据执行数据转换操作，生成以太网数据，再通过所述光纤接口和所述以太网接口输出所述以太网数据。
参见图2，图2示出了本发明实施例的一种IP视频编码器的内部结构示意图。
在本发明的一个示例中，所述信源数据包括视频数据，所述数据处理中心包括扩展芯片、交换芯片和多个IP编码芯片；所述数据转换操作包括数据压缩操作和数据编码操作；

为了在增加系统视频流采集处理容量的同时，又可以灵活选择不同通道或进行通道备份，保证IP视频编码器的处理效率。可以通过扩展芯片分别与多个IP编码芯片通信连接，当所述数据采集端口采集到视频数据后，经所述扩展芯片将所述视频数据分别发送到多个IP编码芯片，由多个IP编码芯片按照各自的编码方式执行数据编码操作，生成中间数据后再执行数据压缩操作，以生成与多个视频数据分别对应的以太网数据。
值得一提的是，多个IP编码芯片主要在于编码时延有所差异，例如IP编码芯片1和IP编码芯片2，其中编码方式可以包括H.264、H.265或私有协议编码等，本发明实施例对此不作限制。

其中，USB数据的处理过程需要将移动设备的USB接口连接到USB 集线器上，通过USB集线器获取到USB数据并发送到多个IP编码芯片，由所述IP编码芯片对所述USB数据进行进一步的编码压缩，以输出期望数据；
同理，音频数据可以通过音频I/O接口进行接收，通过IP编码芯片对音频数据的处理后，生成处理数据可以通过音频I/O接口进行输出，或者通过以太网接口或光纤接口进行输出。
而为了能够更为灵活地控制IP编码芯片的工作状态，还可以通过中控接口接收中控数据，通过中控数据对所述IP编码芯片的工作状态进行控制。
可选地，所述IP编码芯片可以通过红外信号进行控制，或者通过串口通信进行控制，因此，所述中控数据可以包括红外信号数据、RS232信号数据或RS485信号数据。
在本发明的另一个示例中，所述中控接口还用于控制预置信源的开机或关机；所述预置信源用于产生所述信源数据。

进一步地，所述电源模块包括整流模块；
所述整流模块与所述以太网接口连接；
所述整流模块用于按照预置POE协议对所述初始电压执行滤波操作和整流操作，得到目标电压；所述目标电压为所述IP视频编码器的额定电压。
在本发明的可选实施例中，从所述以太网接口获取到的初始电压通常不是IP视频编码器的额定电压。为此，所述电源模块中还设置有整流模块，通过整流模块与所述以太网接口连接，当所述以太网接口获取到来自POE交换机发送的初始电压时，通过整流模块按照预设POE协议，对所述初始电压执行滤波操作和整流操作，以得到目标电压。而通过上述整流模块与以太网接口的组合，实现了利用交换机组局域网或交换机进行供电的技术目的，相对于传统的IP视频编码器，可以减少供电线的设置，布线更加灵活。
可选地，所述电源模块包括整流模块、电源切换模块和外部供电模块；所述电源切换模块分别与所述整流模块和所述外部供电模块连接；所述整流模块与所述以太网接口连接；

或者，
当所述整流模块无法为所述IP视频编码器提供所述目标电压时，切换至所述外部供电模块为所述IP视频编码器提供预置标准电源的电压
在具体实现中，所述电源模块可以包括整流模块、电源切换模块和外部供电模块，所述电源切换模块分别与所述整流模块和所述外部供电模块连接；当所述以太网接口接收到来自POE交换机发送的初始电压后，通过所述整流模块按照预置POE协议对所述初始电压执行滤波操作和整流操作，得到目标电压；同时，为进一步保证所述IP视频编码器的供电，所述外部供电模块也可以通过获取预置标准电源的电压，以提供给IP视频编码器以额定电压。
但在实际使用过程中，可能由于某些意外因素而导致供电中断，例如电网故障导致的停电等，此时可以通过电源切换模块在外部供电模块或整流模块无法提供额定电压时，自动切换至另一供电模块，以保证所述IP视频编码器的供电需求，例如当外部供电模块无法供电时，切换至整流模块进行供电。
在本发明的另一实施例中，所述POE交换机为千兆交换机，千兆交换机可以采用带POE功能的电口交换机。
可选地，所述以太网接口与所述POE交换机的线缆连接方式为网线连接；
所述光纤接口与所述POE交换机的线缆连接方式为光纤连接。
可选地，所述以太网接口可以为RJ45接口。
在本发明实施例中，提供了一种视频编码系统，包括线缆连接的IP视频编码器和POE交换机，其中所述IP视频编码器通过数据采集断开采集信源数据，经数据处理中心对所述信源数据执行数据转换操作后生成以太网数据，通过光纤接口或以太网接口进行以太网数据的输出；同时通过POE交换机与以太网接口的连接，获取到POE交换机提供的初始电压，通过电源模块将所述初始电压调整为IP视频编码器的额定电压，相较于现有的IP视频编码器去除了供电线的限制，使IP视频编码器的布线更加灵活，无需花费大量人力物力去关注现场的电力系统走线，使IP视频编码器的组网和扩容便利性增加，提高IP视频编码器的使用灵活性。
在本发明所提供的几个实施例中，应该理解到，所揭露的系统可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
