图 1为本发明实施例的视频播放系统的示意图;
图 2为本发明实施例的接入视频服务的方法的流程图;
图 3为本发明实施例的接入视频服务的方法的应用示例的流程图。
本发明的较佳实施方式
本发明主要的解决方案是, 当非法用户通过获取的节目的 RTSP的播放 URL接入视频播放系统中时, 业务管理服务器能判断出该用户的接入是非法 接入还是合法接入, 对于非法接入则拒绝提供服务, 从而实现杜绝非法用户 盗链的可能。 因此, 本发明的关键是: 为了实现防非法盗链, 必须保证每次 服务的 RTSP播放的 URL只能提供一次服务。
下面结合附图及实施例对本发明的技术方案进行更详细的说明。
图 1为本发明实施例的视频播放系统的示意图, 如图 1所示, 本实施例 的视频播放系统包括: 业务管理服务器和流媒体服务器。
当业务管理服务器接收到视频服务请求时, 业务管理服务器生成实时流 传输协议(RTSP )播放的 URL, 其中 URL附加一个认证码, 并将认证码的 状态设为未使用, 然后将该附带有认证码的 URL发送给播放终端。
本实施例中, 业务管理服务器可以包括 EPG模块和应用平台模块, 当
EPG模块接收到播放终端发来的视频服务请求时, 向应用平台模块发起鉴权 请求应用平台模块接收到该鉴权请求后, 对该视频服务请求进行鉴权, 判断 用户是否订购了该节目, 若鉴权通过, 则生成一个认证码, 该认证码按照一 定的规则生成, 以保证不会出现重复的认证码。 若鉴权没通过, 则向 EPG模 块返回一鉴权失败消息, 以通知用户。 当认证码生成之后, 应用平台模块将 认证码的状态设为预定值, 例如未使用。 进一步地, 应用平台模块保存该认 证码的相关信息。 然后应用平台模块向 EPG模块返回鉴权通过消息, 携带所 生成的认证码。 EPG模块收到鉴权通过消息后生成 RTSP播放的 URL, 然后 将该 URL及认证码发送给播放终端。
当流媒体服务器接收到播放终端发来的建立 RTSP链路的请求消息时, 解析出所述请求消息中附带的认证码,将所述认证码发送给业务管理服务器, 具体地, 将认证码发送给应用平台模块。
业务管理服务器 (即, 应用平台模块)接收到流媒体服务器发来的认证 码时, 对所述认证码的预定值进行校验, 若认证码有效, 则向流媒体服务器 返回认证成功消息, 并将该认证码删除或置成无效; 流媒体服务器接收到业 务管理服务器发来的认证成功消息后与播放终端建立 RTSP链路。
这样当媒体播放链路被盗链时, 非法用户获取的 RTSP播放的 URL中附 带的认证码已被置成无效或者已被删除, 则业务管理服务器对该认证码的认 证不通过, 并向流媒体服务器返回认证失败消息; 流媒体服务器接收到业务 管理服务器发来的认证失败消息, 则不与播放终端建立 RTSP链路, 因而防 止非法用户盗链, 保证视频播放的安全性和可靠性。
本实施例的视频播放系统可以是 IPTV系统、 也可以是互联星空系统等。
图 2为本发明实施例的接入视频服务的方法的流程图, 如图 2所示, 本 实施例的方法包括以下步骤:
101、 机顶盒或其它播放终端向视频播放系统(例如 IPT V系统 )发起进 行视频服务请求;
例如, 用户通过业务管理服务器的电子节目单 ( EPG )模块进行视频服 务(包括直播点播等) 。
102、 视频播放系统生成 RTSP播放的 URL, 在 URL 中附加一个令牌 ( Token, 也可称作认证码) ; 业务管理服务器按照一定的规则生成一个认证码, 保证不会出现重复的 认证码, 当认证码生成之后, 将其状态设为未使用。
103、 视频播放系统保存该认证码的记录信息。
104、 机顶盒或其它播放终端发起和视频播放系统建立 RTSP链路; 流媒体服务器接收到播放终端发来的建立 RTSP链路的请求消息时, 流 媒体服务器向业务管理服务器触发服务开始的请求, 在请求信息中附带从播 放 URL解析出的认证码。
105、 视频播放系统判断认证码是否存在和有效;
业务管理服务器收到流媒体服务器发出的服务开始请求时, 判断认证码 是否存在和有效, 如果认证码存在且有效, 则转入步骤 106; 否则转入步骤 108。
106、 视频播放系统将该次服务对应的认证码置成无效或者删除; 业务管理服务器向流媒体服务器返回认证成功消息, 并同时将该次服务 对应的认证码置成无效或者删除。
107、 视频播放系统和播放终端建立 RTSP链路;
流媒体服务器收到业务管理服务器的认证成功消息后, 和播放终端建立 RTSP链路并提供视频服务。
108、 拒绝提供视频服务;
当用户通过抓包等手段非法获取 RTSP播放的 URL之后, 随即向流媒体 服务器发起的媒体播放请求, 由于非法获取 RTSP播放的 URL中对应的认证 码已经被合法用户使用, 该认证码的状态已被置成无效或已被删除, 因此业 务管理服务器给流媒体服务器返回认证失败信息。
流媒体服务器收到业务管理服务器返回的认证失败信息后, 拒绝为该用 户提供服务, 从而有效防止了盗链情况的发生。
图 3为根据本发明实施例的接入视频服务的方法的应用示例的流程图, 如图 3所示, 具体步骤如下: 201 : 机顶盒或其它播放终端向 EPG模块发起 VOD ( Video-On-Demand , 视频点播)或直播服务请求;
202: EPG模块向后台 APP ( application platform, 应用平台)模块发起鉴 权请求, 业务管理服务器包括 EPG模块和 APP模块;
203: APP模块对用户进行鉴权, 判断用户是否订购了该节目, 如果该用 户可以点播该节目, 为该次服务生成一个令牌(Token ) , 并在业务管理服务 器中保存该令牌 Token信息, 将该令牌的状态设为未使用, 然后 APP模块将 令牌(Token )信息返回给 EPG模块;
204: EPG模块生成此次服务的 RTSP播放的 URL, URL中附带本次服 务生成的一个令牌(Token ) , 将该带有令牌的 URL发送给播放终端。
205: 播放终端通过 RTSP播放的 URL和 SS ( Streaming Server, 流媒体 服务器)建立连接, 请求视频服务。
206: SS提取出 URL中的令牌信息, 向 APP模块发出的服务开始请求, 进行合法性校验。
207: APP模块收到 SS发出的服务开始请求时, 判断令牌信息是否存在 和有效, 如果令牌是有效的, 则执行步骤 208, 否则执行步骤 210。
208: APP模块向 SS返回校验成功消息, 并同时将该次服务对应的令牌 ( Token )置成无效或者删除该令牌。
209: SS开始给用户提供视频服务。
210: APP模块向 SS返回校验失败消息, SS拒绝给用户提供服务。
本实施例的接入视频服务的方法可以应用于所有视频领域, 如 IPTV、 互 联星空等。
尽管为示例目的, 已经公开了本发明的优选实施例, 本领域的技术人员 将意识到各种改进、 增加和取代也是可能的, 因此, 本发明的范围应当不限 于上述实施例。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块 /单元可以釆用 硬件的形式实现, 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
工业实用性 本发明提供的接入视频服务的方法及视频播放系统能够防止非法用户盗 链, 保证视频播放的安全性和可靠性; 有效利用了原有接入视频服务流程的 鉴权机制, 使得产生 RTSP的认证码的过程不会为系统带来新的负担; 充分 发挥各个 EPG的服务能力, 保证业务管理系统具有较好的持续服务能力; 大 大提高了交互式网络电视系统和媒体播放链路的安全性, 保证了用户和运营 商的合法利益。
