具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。请参阅图1，本申请第一实施例提供了一种数据传输装置100，包括第一网卡接口110、第一音视频转AVT接口芯片120以及第一网络变压器130；所述第一网卡接口110内设置有第三引脚对以及用于实现以太网数据传输第一引脚对和第二引脚对；其中，所述第一网络变压器130连接所述第一引脚对以及所述第二引脚对；所述第三引脚对的两个引脚分别连接所述第一音视频转AVT接口芯片120。
在本实施例中，所述第一网卡接口110可为RJ45接口，例如，为用于以太网网卡、路由器以太网接口等数据终端设备类型的RJ45接口。其中，RJ45接口内至有4对引脚对(8个引脚)，以分别对应连接网线的4对双绞线(8条线芯)。其中，标记这4对引脚对为第一引脚对(包含第一引脚和第二引脚)、第二引脚对(包含第三引脚和第六引脚)、第三引脚对(包含第四引脚和第五引脚)、第四引脚对(包含第七引脚和第八引脚)。根据目前的定义，在传输以太网数据时，第一引脚(TX+)设置为发送数据+，第二引脚(TX-)设置为发送数据-，第三 引脚(RX+)设置为接收数据+，第六引脚(RX+)设置为接收数据-。而剩下的第四、五、七、八引脚则未使用。
在本申请的其他实施例中，也可定义第一引脚对包含第三引脚和第六引脚，第二引脚对包含第一引脚和第二引脚，第三引脚对包含第七引脚和第八引脚)、第四引脚对包含第四引脚和第五引脚，这些方案均在本申请的包含范围之内。
在本实施例中，所述第一网络变压器130连接所述第一引脚对以及所述第二引脚对，以实现基于以太网的供电或者受电，基于以太网的供电(POE)指的是在相关技术中的以太网五类线(Category 5 cable，Cat.5)布线基础架构不作任何改动的情况下，在为一些基于互联网协议(Internet Protocol，IP)的终端(如IP电话机、无线局域网接入点(Access Point，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。在利用POE技术给受电终端设备供电时，有两种实现方案，第一种是占用(1，2，3，6)线芯(对应第1，2，3，6引脚)；第二种是占用(4，5，7，8)线芯(对应第4，5，7，8引脚)，本实施例采用的是第一种实现方案。
在本实施例中，第一音视频转AVT接口芯片120可将音视频信号转换为AVT视频数据，并将所述AVT视频数据通过所述第三引脚对进行传输。
其中，AVT技术具有全数字架构和数字信号传输的优点。为了克服由于数字信号在传输线缆上的衰减所带来的传输距离上的限制，AVT技术采用了新一代数字视频压缩算法。这种算法比标准的视频压缩低延迟(Video Compress-2Low Delay，VC-2LD)压缩算法更为有效。而且，视频延迟极小(小于一帧图像周期)，人眼完全察觉不到，可以认为就是实时的。不仅如此，创新的速率自适应传输技术，根据传输的距离和信号的衰减，可以自适应调整数字压缩比例，以达到最佳的视频图像效果。
其中，所述第一音视频转AVT接口芯片120可为美国国家半导体(National Semiconductor，NS)2510/NS2520/NS2530芯片，其具有至少一对输出差分线(串行数据输出(Serial Digital OUT，SDO)+\SDO-)，以分别连接所述第三引脚对的两个引脚来实现AVT视频数据的传输。
其中，NS2510/NS2520/NS2530芯片视频输入接口兼容10/20bit位宽，且具BT656/1120、CEA-861、CPI、DVP等多种视频格式，最大支持画面分辨率为1920 ×1080，画面流畅度为每秒30帧(1080progressive scan@30frame per second，1080P@30fps)，同时支持数字音频接口(Sony/Philips Digital Interface，SPDIF)/集成电路内置音频(Inter—Integrated Circuit Sound，I2S)音频嵌入。
以下简述本申请实施例的数据传输装置100的工作原理。
在本实施例中，一方面，所述第一音视频转AVT接口芯片120可接收外部装置发送的音视频数据，同时将所述音视频数据转换为AVT视频数据后传输至第三引脚对，由与所述第三引脚对连接的网线的线芯进行AVT视频数据的传输。另一方面，外部设备发送的以太网数据和直流供电通过第一引脚对和第二引脚对传输到所述第一网络变压器130，再传输到受电端，从而基于本实施例的数据传输装置100可以利用一个网卡接口和网线同时实现音视频数据的传输、以太网数据的传输以及POE受电(或者供电)。
在本申请的一个可选实施例中，所述数据传输装置100还包括第二音视频转AVT接口芯片140，所述第四引脚对的两个引脚分别连接所述第二音视频转AVT接口芯片140的另一对输出差分线。
在一些情况下，需要同时传输两路或者更多路的音视频数据，则此时，可以进一步在增加第二音视频转AVT接口芯片140，并连接到处于空闲状态的第四引脚对，从而实现两路音视频数据的传输。
例如，对于网络摄像机传输的同时包含全景的音视频数据以及包含特写的音视频数据，可将这两路音视频数据分别通过第一音视频转AVT接口芯片120以及第二音视频转AVT接口芯片140及其对应的引脚对进行传输。
本申请第二实施例还提供了一种数据传输设备，包括如上述任一实施例所述的的数据传输装置100。

在本实施例中，由数据传输装置100通过网线传输的AVT视频数据或以太网数据通过所述网线传输到所述第二网卡接口210，经由第二网卡接口210的相应引脚被传输到相应的元件。例如，AVT视频数据由所述第三引脚对传输到AVT接口转音视频芯片220以转换为音视频数据。以太网数据经由第一引脚对以及第二引脚对传输到第二网络变压器230。
此外，所述数据接收装置200也可以通过所述第二网卡接口210发送以太网数据或者直流供电，以太网数据或者直流供电通过网络发送给数据传输装置100的第一网卡接口110的第一针脚对和第二针脚对，再经第一网络变压器130，实现以太网数据的传输和供电。
在本实施例中，所述AVT接口转音视频芯片220为双路AVT接口转音视频芯片；所述第四引脚对连接所述双路AVT接口转音视频芯片。
其中，针对数据传输装置100同时传输两路音视频数据流的情况，这里的AVT接口转音视频芯片220采用了双路AVT接口转音视频芯片。第四引脚对也与所述AVT接口转音视频芯片220连接，从而AVT接口转音视频芯片220可以同时接收由两路音视频数据转换的AVT视频数据，并同时转换为音视频数据，以进行播放显示。
其中，所述AVT接口转音视频芯片220可NS2511/NS2521/NS2531芯片，NS2511/NS2521/NS2531芯片作为解码芯片与NS2510/NS2520/NS2530芯片配对使用，不仅全面支持NS2510/NS2520/NS2530芯片格式，而且可同时接收两路信号。
本申请第四实施例进一步提供了一种数据接收设备，包括如上述任一实施例所述的数据接收装置200。
在本实施例中，所述数据接收设备还可以包括数据显示模块、电源，其中，AVT接口转音视频芯片220生成的音视频数据发送至显示模块进行显示。电源与所述第二网络变压器230连接，以通过所述第二网络变压器230输出符合要求的直流供电。
请参阅图3，本申请第五实施例还提供了一种数据传输系统，包括如上述任一实施例的数据传输设备以及如上述任一实施例的数据接收设备；所述数据传输设备的第一网卡接口与所述数据接收设备的第二网卡接口通过网线连接。
其中，在上述的描述中，所述数据传输设备作为受电端，而所述数据接收设备作为供电端，但在本申请的其他实施例中，所述数据传输设备也可以作为供电端，而所述数据接收设备作为受电端，这些方案均在本申请的保护范围之内。
