详述
在下文中，仅简单地描述了某些示例性实施例。正如本领域技术人员可认识到的那样，在不脱离本公开的精神或范围的情况下，可通过每种不同方式修改所描述的实施例。因此，附图和描述被认为本质上是示例性的而非限制性的。
在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
前述为了防止投放内容被篡改的相关方案具有以下缺陷：由于增加了硬件，导致成本升高，而且摄像头拍摄画面会受周围环境等干扰因素的影响，使得误识别率较高。为此，本公开实施例提供一种监测投放内容的方法、装置和系统，以实现投放内容的自动监测，降低成本，提高准确性及降低误识别率。该技术方案涉及媒体播放终端和服务器。其中，媒体播放终端通常是指可以播放多媒体信息的显示设备，主要功能为展示播放内容，安装地点包括但不限于公交车站、电梯、机场、商场等公共场所。服务器是指具有下发和识别功能的设备，与媒体播放终端远程通信，可以下发动态校验码和投放内容(如广告)给媒体播放终端，还可以对媒体播放终端上传的包含动态校验码的截屏图像进行识别，以判别投放内容在媒体播放终端侧播放是否异常，从而达到监测及报警的目的。
参见图1，本公开一实施例提供了一种监测投放内容的方法，应用于媒体播放终端，包括：
S101：接收服务器下发的投放内容和校验信息；
其中，投放内容可以为多媒体信息，如广告商提供的广告视频等等，本实施例对此不做限定。
S102：解析校验信息得到至少一个动态校验码；
其中，上述动态校验码可以包括文字、数字、符号和形状中的至少一种。
S103：将动态校验码渲染至投放内容的播放画面中；
其中，渲染是指用软件从模型生成图像的过程，模型是用严格定义的语言或者数据结构对于三维物体的描述，它包括但不限于几何、视点、纹理以及照明信息。本实施例中的渲染为将动态校验码生成对应的图像并合成至播放画面中。
S104：截屏播放画面得到截屏图像；
其中，截屏是指截取显示屏幕上的信息，是一种截取图像的途径。本实施例中，对动态播放的画面进行截屏，可以得到截屏时刻对应的画面图像，为了方便理解，可以称为截屏图像，对于播放的视频而言，可以理解为截屏 得到某一时刻对应帧的图像。
S105：将截屏图像上传至服务器，截屏图像用于服务器监测投放内容是否异常。
在一种实施方式中，上述步骤S103可以包括：
当解析校验信息还得到位置信息时，按照位置信息指定的位置将动态校验码渲染至投放内容的播放画面中。
在另一种实施方式中，上述步骤S103可以包括：
当解析得到多个动态校验码和各自对应的有效期时，确定当前时刻所在的有效期，将有效期对应的动态校验码渲染至投放内容的播放画面中。
在另一种实施方式中，上述步骤S103可以包括：
当解析所述校验信息得到位置信息、多个动态校验码和每个动态校验码对应的有效期时，确定当前时刻所在的有效期，按照所述位置信息指定的位置将所述有效期对应的动态校验码渲染至所述投放内容的播放画面中。
本实施例中，服务器下发的信息还可以先进行加密处理，媒体播放终端收到后先进行相应的解密，然后再执行后续操作，从而提高数据的安全性。其中涉及的加密解密算法有多种，包括但不限于：MD5(Message-Digest Algorithm，信息摘要算法)、SHA1(Secure Hash Algorithm 1，安全散列算法1)、HMAC(Hash-based Message Authentication Code，密钥相关的哈希运算消息认证码)、AES(Advanced Encryption Standard，高级加密标准)/DES(Data Encryption Standard，数据加密标准)/3DES、RSA(Rivest-Shamir-Adleman算法)、ECC(Error Correcting Code，误差校正码)等等。
本实施例提供的上述方法，通过将服务器下发的动态校验码渲染至投放内容的播放画面中，并截屏得到截屏图像上传至服务器以监测投放内容是否异常，实现了投放内容的自动监测，无需配置单独的采集设备，降低了成本，且基于截屏图像监测能够排除周围环境的干扰因素，与采集设备相比，图像更清晰，从而提高了准确性，降低了误识别率，而且基于动态校验码极大地 提高了投放内容被篡改的难度。
参见图2，本公开另一实施例提供了一种监测投放内容的方法，应用于服务器，包括：
S201：生成包含至少一个动态校验码的校验信息，该动态校验码用于媒体播放终端渲染至投放内容的播放画面中；
其中，上述动态校验码可以包括文字、数字、符号和形状中的至少一种。
S202：将投放内容和校验信息下发给媒体播放终端；
S203：接收媒体播放终端截屏播放画面后发送的截屏图像；
其中，媒体播放终端的截屏图像中包含有收到的动态校验码，因此，可以以此为基础进行校验。
S204：根据截屏图像监测媒体播放终端的投放内容是否异常。
在一种实施方式中，上述步骤S204可以包括：
从截屏图像中解析出动态校验码，与本地生成的动态校验码进行比对，根据比对结果确定媒体播放终端的投放内容是否异常。
在一种实施方式中，根据比对结果确定媒体播放终端的投放内容是否异常包括：当比对结果为匹配度小于阈值时，确定媒体播放终端的投放内容异常。其中，匹配度是指解析出的动态校验码和本地生成的动态校验码二者之间的匹配度，可以采用相似度等多种匹配算法来计算，此处不做具体限定。上述阈值可以根据需要设置，如70％，80％或90％等等，具体数值不限定。
在一种实施方式中，根据比对结果确定媒体播放终端的投放内容是否异常包括：包括：
当比对结果符合匹配度小于阈值且比对次数达到指定次数时，确定媒体播放终端的投放内容异常。
其中，指定次数可以根据需要预先设置，如3次或5次等等，本文对数值不限定。例如，比对3次且3个匹配度均小于阈值80％，则确定投放内容异常。
上述基于匹配度识别异常的方式，可以通过设置阈值来改变识别精度， 如通过增加阈值的数值来提高识别的精度，通过减少阈值的数值来降低识别的精度，设置方式灵活方便，容易实现。上述基于匹配度和比对次数识别异常的方式，可以为监测设置一定的误差率，避免由于网络延迟或传输出错等意外干扰因素，而导致识别错误，即在指定次数允许的范围内不识别为异常，只有超过指定次数才识别为异常，从而提高了兼容性，应用更灵活。
在一种实施方式中，上述校验信息还包括位置信息，该位置信息用于指定动态校验码在播放画面中的渲染位置；或上述校验信息包括多个动态校验码且每个动态校验码具有有对应的有效期；上述检验信息包括位置信息、多个动态校验码且每个动态校验码具有对应的有效期。
本实施例提供的上述方法，通过生成动态校验码并下发至媒体播放终端，接收媒体播放终端将动态校验码渲染至播放画面后截屏且发送的截屏图像，基于该截屏图像监测投放内容是否异常，实现了投放内容的自动监测，无需配置单独的采集设备，降低了成本，且基于截屏图像监测能够排除周围环境的干扰因素，与采集设备相比，图像更清晰，从而提高了准确性，降低了误识别率，而且基于动态校验码极大地提高了投放内容被篡改的难度。
参见图3，本公开另一实施例提供了一种监测投放内容的方法，应用于媒体播放终端，包括：
S301：接收服务器下发的投放内容和校验信息；
S302：解析校验信息得到位置信息和多个动态校验码，以及每个动态校验码对应的有效期；
其中，上述动态校验码可以包括文字、数字、符号和形状中的至少一种。上述位置信息可以为像素坐标信息，根据该位置信息可以确定出动态校验码在播放画面上的显示位置。为了尽量避免对正常投放内容的干扰，影响用户观看，优选地，可以通过位置信息将动态校验码的显示位置设置在播放画面的边缘或角落等位置，且可以尽量设置尺寸较小，以用户不易观察到为宜，从而能够保证用户的体验流畅。
上述有效期通常可以为一段时间，如一天、一周或一个月等等。在有效 期内动态校验码为有效，超过该有效期，则动态校验码无效。在有多个动态校验码的情况下，可以为每个动态校验码设置一个有效期，通常设置为不同的有效期，且可以设置为连续的有效期，如周一至周日设置7个动态校验码，每个动态校验码的有效期为1天等等，本文对此不限定。
S303：确定当前时刻所在的有效期，将该有效期对应的动态校验码，按照上述位置信息指定的位置渲染至投放内容的播放画面中；
例如，当前时刻为周一的上午10:00，对应有效期为周一至周五，则选择该有效期内的动态校验码来进行渲染。
S304：截屏播放画面得到截屏图像；
其中，截屏可以对播放画面的整个屏幕进行截屏，也可以对局部区域进行截屏，只要包含动态校验码即可，本文对此不限定。截屏的操作可以定期进行，如设置一定的周期，周期到达即截屏上传，从而使得服务器可以依据多次截屏结果进行识别监测，提高监测的准确性。
S305：将截屏图像上传至服务器，截屏图像用于服务器监测投放内容是否异常。
其中，截屏图像也可以先进行加密再上传服务器，服务器收到后先进行解密再执行后续操作，以提高安全性，关于加密解密的过程此处不再赘述。
参见图4，为本公开一实施例的媒体播放终端监测投放内容的示意图。如图所示，媒体播放终端具有播控功能和截屏功能，在收到服务器下发的播放素材和动态校验码后，通过播控功能可以进行播放操作，且同步可以解析出动态校验码并渲染至播放画面中。在播放的过程中，通过截屏功能可以定期截屏得到截屏图像上传至服务器，触发服务器进行播放内容是否异常的监测。
参见图5，本公开另一实施例提供了一种监测投放内容的方法，应用于服务器，包括：
S501：生成包含动态校验码和位置信息的校验信息，该动态校验码用于媒体播放终端渲染至投放内容的播放画面中，该位置信息用于指定动态校验 码在播放画面中的渲染位置；
其中，上述动态校验码可以包括文字、数字、符号和形状中的至少一种。
在一种实施方式下，上述动态校验码可以为多个且有各自对应的有效期。
S502：将投放内容和校验信息下发给媒体播放终端；
S503：接收媒体播放终端截屏播放画面后发送的截屏图像；
S504：从截屏图像中解析出动态校验码，与本地生成的动态校验码进行比对；
S505：在匹配度小于阈值的情况下，确定媒体播放终端的投放内容异常。
在一种实施方式下，上述方法还可以包括：
在确定媒体播放终端的投放内容异常之后，发送报警信息，提示投放内容异常。其中，报警信息可以发送给业务服务器，由业务服务器进行相应处理或者提示给相关人员，由人工复查及时处理，修复异常等。
例如，本地生成的动态校验码为文字“智慧公交”，从截屏图像中解析出的动态校验码为“智慧”，则匹配度为50％，小于阈值80％，则可以确定投放内容异常。
在一种实施方式下，上述步骤S505可以包括：
在符合匹配度小于阈值且比对次数达到指定次数的情况下，确定媒体播放终端的投放内容异常。
其中，符合匹配度小于阈值是指在该指定次数之内，每次比对的匹配度都小于阈值。
参见图6，为本公开一实施例的服务器监测投放内容的示意图。如图所示，服务器，服务器具有业务功能和图像识别功能，通过业务功能可以生成动态校验码，并与播放素材一起下发给媒体播放终端，在收到媒体播放终端上传的截屏图像后，基于图像识别功能从截屏图像中解析出动态校验码，并与本地生成的动态校验码进行比对，根据比对结果确定媒体播放终端的播放内容是否异常。

其中，上述动态校验码可以包括文字、数字、符号和形状中的至少一种。
本实施例提供的上述装置，通过将服务器下发的动态校验码渲染至投放内容的播放画面中，并截屏得到截屏图像上传至服务器以监测投放内容是否异常，实现了投放内容的自动监测，无需配置单独的采集设备，降低了成本，且基于截屏图像监测能够排除周围环境的干扰因素，与采集设备相比，图像更清晰，从而提高了准确性，降低了误识别率，而且基于动态校验码极大地提高了投放内容被篡改的难度。
