Description

一种监控视频播放的方法及设备、 系统 本申请要求于 2013 年 4 月 17 日提交中国专利局、 申请号为 201310134227.0、 发明名称为"一种监控视频播放的方法及设备、 系统" 的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种监控视频播放的方法及设备、 系统。
背景技术
网络视频监控业务是基于宽带的远程图像监控、 传输、 存储、 管理 的增值业务。 网络视频监控业务利用宽带网络将分散、 独立的图像釆集 点进行联网, 实现跨地域、 全范围内的统一监控、 统一存储、 统一管理、 资源共享。
为进一步辅助做监控决策, 可以在前端设备处连接数据釆集器, 用 于釆集监控点附近的环境数据。 数据釆集器可以是温度湿度釆集器、 风 向风速釆集器、 噪声釆集器等等。 这些釆集到的数据可以用来做事后的 查询和分析, 也可能直接在监控期间就调用。
一些监控设备在用户调用监控视频时, 将前端釆集的釆集数据直接 在源头编码时就与视频数据(即视频流)叠加并展示给监控人员。但是这种 釆用源头叠加的方式, 让所有人都必须看到这些数据, 但是并不是所有 人都需要查看釆集数据, 监控视频的播放方式不够灵活。

具体实施方式
参阅图 1, 图 1为本申请视频监控系统一个实施方式的结构示意图, 本实 施方式视频监控系统包括客户端设备 100、 视频监控管理设备 200、 前端设备 300以及釆集器 400。 其中, 客户端设备 100是承载客户端功能的具体实体设 备或虚拟设备, 主要实现监控人员查看监控视频以及釆集数据功能。视频监控 管理设备 200通过网络与客户端设备 100以及前端设备 300实现通信,主要实 现监控视频数据以及釆集数据的管理、客户端设备用户的权限管理等功能。根 据应用场景的不同,客户端设备 100和视频监控管理设备 200可以是单独设置 于视频监控系统中的实体设备,也可以作为一个功能模块集成于现有视频监控 设备中, 比如集成在用户终端设备上, 在用户终端设备上同时实现客户端设备
100以及视频监控管理设备 200的功能。
比如客户端设备 100可以以软件形式来实现客户端功能,安装于用户终端 设备内,可能是通过手机终端、掌上电脑 (Personal Digital Assistant, PDA), PAD, 个人计算机 (personal computer, PC), 监控中心设备等来实现客户端功能。 承 载客户端设备 100还包括视频解码器、 大屏、 监控键盘、 服务器等功能模块, 共同完成用户的监控任务。本申请实施方式中, 为实现更好地输出视频监控的 结果, 必要时还需要设置视频智能分析单元, 用来完成对视频的智能分析并输 出结果的工作。视频智能分析单元的物理表现形态可以是一台服务器或一台专 业设备, 或与视频监控管理设备 200同属一台服务器中, 或者集成在前端设备 300中, 亦或是以软件形态包含于客户端设备 100软件中安装在用户终端设备 上。 客户端设备 100提供用户一般的视频监控、 录像查询回放、 云镜控制、 告 警通知与联动等功能。
视频监控管理设备 200 按功能的其中一种划分方式可以包括以下逻辑单 元: 业务管理单元、 业务控制单元、 接入网关单元、 媒体分发转发单元、 媒体 录像存储回放单元、 数据库 /磁盘存储单元。
业务管理单元主要用于视频监控管理设备与用户管理以及用户的权限管 理;业务控制单元主要用来处理前端设备的运行控制,包括请求前端设备视频、 控制前端设备云镜、 处理前端设备告警、 完成前端设备的录像计划等业务, 以 及处理用户的登录注销,接收来自客户端设备 100的用户请求与处理, 将告警 联动通知到用户侧等业务;接入网关单元主要用来处理前端设备与客户端设备 的注册,保持其在线状态等功能; 媒体分发转发单元主要用来处理前端设备或 存储中的视频分发或转发到相应目的地去的业务功能;媒体录像存储回放单元 主要处理将视频存储在磁盘中,或将磁盘中录像通过媒体分发转发单元发送到 客户端设备 100的功能; 数据库 /磁盘存储单元主要是保存数据的模块, 其可 能是服务器本身的磁盘, 也可能是外接的存储磁盘阵列设备。
这里的单元划分只是一种逻辑功能划分举例,实际实现时可以有另外的多 种划分方式, 比如多个单元可以结合集成一个功能模块, 存在于一台或多台通 用或专用服务器中来实现各自的功能, 或一些特征可以忽略, 或不执行。
前端设备 300为视频釆集设备,比如可以是网络视频摄像机或模拟摄像机 和视频编码器, 前端设备 300主要完成视频数据的釆集工作,将视频数据通过 网络传送到视频监控管理设备 200中,并响应视频监控管理设备 200发送的控 制命令。 比如向视频监控管理设备 200提供实时浏览和前端录像的视频数据、 提供云镜控制能力、提供对前端各参数的配置能力、 以及提供前端设备的告警 能力等。
釆集器 400是用于釆集前端设备 300周边环境信息的设备,本申请实施方 式的釆集器 400可以是一个独立的设备, 通过 RS232或 RS485接口连接到前 端设备上, 其可能是各种釆集设备, 比如但不限于是温湿度釆集器、 风速风向 釆集器、 噪声釆集器等等。 釆集器 400完成釆集监控点附近的环境数据, 以辅 助做监控决策。 另一方面, 本申请实施方式的釆集器 400也可以合在前端设备 内, 以内部模块的方式提供釆集能力。 比如一些摄像机设备自带釆集功能, 完 成摄像机本身温度的釆集。

图中的网络 12用于实现监控视频以及釆集数据等的传输。网络 12可以包 括当今的所有网络, 可能是互联网、 局域网、 广域网、 存储局域网等, 或其适 当的组合。接入网络的方式也可能是当下各种接入方式,如有线(网线或光纤)、 无线, 无线包括 WIFI (例如 IEEE 802.11a、 IEEE 802. lib、 IEEE 802.11g和 / 或 IEEE 802.11η )、 GSM(EDGE), WCDMA、 CDMA, TD-SCDMA、蓝牙、 LTE 或其他任何适合接入方式。

上述的视频监控系统的实施方式,只是本申请对视频监控系统的一个具体 举例说明,在以其他形式实现相同功能的视频监控系统也属于本申请的保护范 围, 在此不——列举说明。
请参阅图 4, 图 4为本申请监控视频播放的方法一个实施方式的流程图, 本实施方式是以上述提到的客户端设备角度来描述, 监控视频播放的方法包 括:
步骤 S101 : 客户端设备向视频监控管理设备发出监控视频浏览请求; 当有用户需要查看监控录像时,向视频监控管理设备发出监控视频浏览请 求, 请求中可以包括需要查看的录像的条件信息, 还可以包括用户信息, 比如 用户账号、用户标识等等。 用户可以发送实时监控视频浏览请求也可以发送历 史监控视频浏览请求。
视频监控管理设备接收到监控视频浏览请求后,对发出请求的用户进行鉴 权,判断发出请求的用户是否有查看跟请求的视频数据相对应的釆集数据的权 鉴权, 本申请对此不做限定。
当视频监控管理设备判断到发出请求的用户有查看釆集数据的权限时,根 据用户的请求条件, 若用户请求是历史监控视频浏览请求, 则找寻到符合条件 的录像索引文件,根据索引文件中的指针地址实际查找到相关的视频数据和釆 集数据, 生成对应用户请求的视频数据和相关联的釆集数据的第一链接地址, 第一链接地址为携带视频数据和釆集数据标记的实时流协议的视频播放链接 地址, 第一链接地址可以是实时流协议统一资源定位符 (Real Time Streaming Protocol Uniform Resource Locator, rtsp url), 并将第一链接地址返回给客户端 设备。 客户端设备执行步骤 S102及之后的步骤。
若用户请求是实时监控视频浏览请求,则视频监控管理设备根据具体请求 的前端设备生成第一链接地址,该第一链接地址内也携带视频数据和釆集数据 标记, 将该第一链接地址发送给客户端设备。
当视频监控管理设备判断到发出请求的用户没有查看釆集数据的权限,向 客户端设备返回第二链接地址,第二链接地址为只携带视频数据标记的实时流 协议的视频播放链接地址, 客户端设备执行步骤 S 105。
步骤 S102: 接收视频监控管理设备返回的第一链接地址;
当发出监控视频浏览请求的用户有查看釆集数据的权限时,视频监控管理 设备端的鉴权通过, 接收视频监控管理设备返回的第一链接地址。
步骤 S103: 根据第一链接地址从视频监控管理设备获取视频数据和釆集 数据;
若用户请求的是历史监控视频浏览时,根据视频监控管理设备返回的第一 链接地址, 向视频监控管理设备发出获取视频数据和釆集数据的请求,视频监 控管理设备根据第一链接地址找到符合条件的录像索引文件,根据索引文件中 的指针地址实际查找到相关的视频数据和釆集数据。将视频数据和釆集数据发 送给客户端设备, 客户端设备接收视频数据和釆集数据。
若用户请求的是实时监控视频浏览时,当客户端设备通过此第一链接地址 来请求数据时,视频监控管理设备再根据此第一链接地址中的信息去获取对应 前端设备的实时视频数据和釆集数据, 并发送给客户端设备。
作为一种可选的方式,客户端设备可以将获取到的视频数据和釆集数据下 载, 以文件格式保存在本地机器中。 下载数据的文件格式保存可以是釆集数据 和视频数据一并保存在同一个文件中,也可以是将釆集数据以类似字幕文件一 般的与视频数据文件分开保存。一并保存的方式可以是将釆集数据扩展在视频 数据文件格式如 MP4、 AVI等的扩展字段中,以时间戳与视频数据建立关联 (如 图 5所示)。 分开保存的方式可以将釆集数据以独立二进制或文本方式保存, 通过相同的文件名与视频数据文件关联。
步骤 S104: 将视频数据和釆集数据叠加后播放。 客户端设备接收到视频数据和釆集数据进行緩存后, 对视频数据进行解 码,对釆集数据进行解析, 将视频数据和釆集数据叠加渲染后以视频画面叠加 透明字幕的方式 (On-Screen Display, OSD)播放。
作为一种更加优选的方式,客户端设备可以根据用户是否选择数据叠加决 定是否叠加 OSD进行播放。
一种叠加播放的实现方式为:客户端设备接收以数据流的方式传送过来的 视频数据和釆集数据,将视频数据的数据流进行緩存, 釆集数据的数据流以元 数据 (MetaData)形式緩存。 当需要叠加播放时,在对视频数据进行解码播放时, 根据釆集数据中包含的时间戳信息,对应查找到緩存的视频数据或录像文件中 视频数据的关联的起始帧。在解码并播放录像的同时,提取与帧相对应的釆集 数据中包含的具体釆集数据信息, 生成相应的字符, 渲染叠加即可显示包含前 端釆集数据信息的视频。
作为一种优选的方式, 可以预先设置釆集数据的最大停留时间, 若在釆集 数据的最大停留时间之后, 没有接收到新的釆集数据, 则无效之前一直显示的 釆集数据(即不再在视频画面中叠加釆集数据)。 如果在预设的最大停留时间 内,接收到新的釆集数据, 则以新的釆集数据替代原有的釆集数据并与当前视 频数据进行叠加后播放。
步骤 S105: 接收视频监控管理设备返回的第二链接地址, 根据第二链接 地址从视频监控管理设备获取视频数据并播放;
当发出监控视频浏览请求的用户没有查看釆集数据的权限时,视频监控管 理设备返回第二链接地址,第二链接地址为只携带视频数据标记的实时流协议 的视频播放链接地址,第二链接地址可以是 rtsp url,根据第二链接地址从视频 监控管理设备获取视频数据并播放。
其中,有查看釆集数据权限的用户通过客户端设备请求视频数据的同时获 取到与视频数据对应的釆集数据的其中一种实现方式可参阅图 6的示意图,通 过以下方式来实现:
前端设备实时监控,得到相应的视频数据传输给视频监控管理设备, 若前 端设备正在录像, 则视频监控管理设备通过录像文件格式保存视频数据;
釆集设备实时釆集信息, 得到相应的釆集数据, 传输给前端设备, 前端设 备将釆集数据传输给视频监控管理设备, 若前端设备正在录像, 则视频监控管 理设备以元数据形式单独存储釆集数据, 得到釆集数据文件;
视频监控管理设备建立录像文件和釆集数据文件索引;
当用户通过客户端设备向视频监控管理设备发送监控视频浏览请求时,视 频监控管理设备找到符合用户条件的录像文件和釆集数据文件索引,进而找到 视频数据和釆集数据传输给客户端设备;
客户端设备解码叠加两者信息以 OSD形式播放, 另外, 客户端设备也可 以将视频数据和釆集数据下载保存在本地机器上, 以后需要再次浏览该录像 时,无需通过向视频监控管理设备请求即可以直接在本地解码叠加视频数据和 釆集数据播放。
通过上述实施方式的阐述, 可以理解, 本申请通过对客户端设备的权限进 行管理,只有通过客户端设备发送请求的用户具有查看釆集数据权限时才将釆 集数据和视频数据发送给客户端设备,并且在用户选择叠加播放时才将视频数 据和釆集数据一起叠加后播放。通过这种方式, 能够灵活的根据发出监控视频 浏览请求的用户权限, 控制是否向客户端设备发送与视频数据相应的釆集数 据,根据用户的选择决定是否一同播放釆集数据,使监控视频的播放更加灵活, 避免不需要查看釆集数据的人也不得不看到釆集数据, 让用户权限最小化, 带 来更高的安全性。
另外, 通过 OSD方式将视频数据和釆集数据叠加播放, 方便在不需要时 或者釆集数据显示一定时间后去掉釆集信息,不会因釆集数据而遮挡录像画面 中的关键信息, 带来更好的体验效果。
请参阅图 7,图 7为本申请监控视频播放的方法另一个实施方式的流程图, 本实施方式是以上述的视频监控管理设备的角度来描述,监控视频播放的方法 包括:
步骤 S201 : 视频监控管理设备接收来自客户端设备的监控视频浏览请求, 根据请求对通过客户端设备发出监控视频浏览请求的用户进行鉴权;
当有用户需要查看监控视频时,向视频监控管理设备发出监控视频浏览请 求, 请求中可以包括需要查看的录像的条件信息, 还可以包括用户信息, 比如 用户账号、用户标识等等。 用户可以发送实时监控视频浏览请求也可以发送历 史监控视频浏览请求。
视频监控管理设备接收到监控视频浏览请求后,对发出请求的用户进行鉴 权,判断发出请求的用户是否有查看跟请求的视频数据相对应的釆集数据的权 鉴权, 本申请对此不做限定。
当视频监控管理设备判断到发出请求的用户有查看釆集数据的权限,鉴权 通过, 生成对应用户请求的视频数据和相关联的釆集数据的第一链接地址, 该 第一链接地址为携带有视频数据和釆集数据标记的实时流协议的视频播放链 接地址, 进行步骤 S202以及之后的步骤。
当视频监控管理设备判断到发出请求的用户没有查看釆集数据的权限,鉴 权没有通过, 执行步骤 S204。
步骤 S202: 向客户端设备发送第一链接地址;
将生成的对应用户请求的视频数据和相关联的釆集数据的第一链接地址 发送给客户端设备,以使客户端设备能够根据该第一链接地址向视频监控管理 设备请求相应的视频数据和釆集数据。
步骤 S203 : 根据客户端设备返回的携带第一链接地址的数据请求, 将视 频数据和釆集数据发送给客户端设备,以使客户端设备能够将视频数据与釆集 数据叠加后播放;
若用户请求的是历史监控视频浏览请求,当客户端设备需要获取请求对应 的视频数据和釆集数据时,向视频监控管理设备发送携带第一链接地址的数据 请求,视频监控管理设备接收到该数据请求后,根据第一链接地址找到符合条 件的录像索引文件,根据索引文件中的指针地址实际查找到相关的视频数据和 釆集数据。 将视频数据和釆集数据发送给客户端设备。
若用户请求的是实时监控视频浏览请求,当客户端设备通过第一链接地址 来请求数据时,视频监控管理设备再根据第一链接地址中的信息去获取对应前 端设备的实时视频数据和釆集数据, 并发送给客户端设备。
本申请实施方式中, 前端设备与釆集器和视频监控管理设备连接, 前端设 备实时从釆集器获取釆集数据,并将釆集数据和自身釆集的视频数据实时传输 给视频监控管理设备。 前端设备将视频数据和釆集数据传输给视频监控管理设备的一种实现方 式可以是通过实时流传输协议 /实时传送协议(Real-Time Streaming Protocol/Real-time Transport Protocol, RTSP/RTP)传输, 与视频数据同步的釆集 数据通过视频数据的传输通道, 扩展 RTP头一并带入。

若用户请求的是实时监控视频,当客户端设备通过此第一链接地址来请求 数据时,视频监控管理设备再根据此第一链接地址中的信息去获取对应前端设 备的实时视频数据和釆集数据, 并发送给客户端设备。
播放模块 24用于将视频数据和釆集数据叠加后播放。
客户端设备接收到视频数据和釆集数据进行緩存后, 通过播放模块 24对 视频数据进行解码,对釆集数据进行解析,将视频数据和釆集数据叠加渲染后 以视频画面叠加透明字幕的方式 (On-Screen Display, OSD)播放。

叠加数据播放时, 播放模块 24根据釆集数据中包含的时间戳信息, 查找 到视频数据中的关联的起始帧, 对视频数据进行解码播放的同时,提取与起始 帧相对应的釆集数据, 渲染叠加后以 OSD方式播放。
作为一种优选的方式, 可以预先设置釆集数据的最大停留时间, 若在釆集 数据的最大停留时间之后, 没有接收到新的釆集数据, 则播放模块 24无效之 前一直显示的釆集数据 (即不再在视频画面中叠加釆集数据)。 如果在预设的最 大停留时间内, 接收到新的釆集数据, 播放模块 24以新的釆集数据替代原有 的釆集数据并与当前视频数据进行叠加后播放。
若用户没有查看釆集数据的权限, 播放模块 24用于播放视频数据。
