这一处理过程具体为:
获取子模块 221获取多个媒体文件和多个加密后文件;选取子模块 225 在多个媒体文件中选择要处理的选定媒体文件, 将选定媒体文件发送给创 建子模块 222; 创建子模块 222提取选定媒体文件的关键帧,创建选定媒体 文件的选定关键帧索引文件; 存储子模块 223将选定媒体文件对应的加密 后文件和选定关键帧索引文件存储在对应的文件夹中。
图 3C所示的分片处理模块 22可以使整个处理系统根据用户的需要进 行选择处理, 功能更完善和人性化。
如图 3D所示, 图 3A (或图 3B、 或图 3C )所示的分片处理模块 22还 可进一步包括提示子模块 226, 其中:
创建子模块 222, 还用于在创建当前媒体文件的关键帧索引文件失败 时, 向提示子模块 226发送处理当前媒体文件失败的消息, 并跳过当前媒 体文件, 继续提取下一个媒体文件的关键帧, 创建下一个媒体文件的关键 帧索引文件;
提示子模块 226, 用于在接收到上述消息后, 显示当前媒体文件处理失 败的提示消息。
另外, 如图 3E所示, 分片处理模块 22还可以包括:
更新子模块 227, 用于对加密后文件和关键帧索引文件进行后处理, 即 根据加密后文件将关键帧索引文件的索引进行重新排序, 使流媒体服务器 能在提供加密后文件的快进快退响应时, 快速准确地查找加密后文件的关 键帧。
更新子模块 227 的处理过程如下: 在加密后文件中查找一遍 ECM ( Entitlement Control Message, 授权控制信息)包, 然后将包信息相应调整 一下, 比如, 原来第 7个 TS ( Transport Stream, 传输流)包是关键帧首包, 现在因为第 6个 TS包后面插入了一个 ECM包, 即 ECM包变成第 7个包, 原来的关键帧首包变成第 8个 TS包, 那么就需要将索引信息调整一下, 关 键帧首包由原来的第 7个 TS包(第二个 RTP ( Real-time Transport Protocol, 实时传送协议) 包), 变成第 8个 TS包 (第三个 RTP包)。
如图 4所示, 本发明实施例提供了一种交互式网络电视中点播节目的 处理方法, 包括:
S401、 加密处理模块对媒体文件进行加密, 得到对应的加密后文件。 其中, 加密处理模块的加密过程同现有技术, 这里不再详述。
需要说明的是, 这里, 加密处理模块并不经中间件获取媒体文件, 而 可以从媒体库直接获取媒体文件。 5402、 分片处理模块获取媒体文件和加密后文件。
5403、 分片处理模块生成媒体文件的关键帧索引文件, 将加密后文件 和关键帧索引文件存储在对应的文件夹中, 文件夹由中间件获取后发送给 片库服务器存储, 并在媒体文件被允许发布后, 由流媒体服务器从片库服 务器获得并从中取得片源后播放给终端。
其中, 步骤 S403具体为:
分片处理模块提取媒体文件的关键帧, 创建媒体文件的关键帧索引文 件;
分片处理模块将加密后文件和关键帧索引文件存储在对应的文件夹 中。
可见, 中间件此时只是作为传输介质, 与加密处理模块没有数据交互, 因此, 中间件不必重复做接口兼容的繁瑣工作。
当媒体文件和加密后文件分别为多个时, 上述处理方法还包括以下步 骤:
分片处理模块在多个加密后文件中, 分别根据文件名确定与每个媒体 文件对应的加密后文件。
这一过程具体为:
A1、 分片处理模块获取多个媒体文件和多个加密后文件;
A2、 分片处理模块分别提取多个媒体文件中每个媒体文件的关键帧, 创建每个媒体文件的关键帧索引文件;
A3、 在多个加密后文件中, 分别根据文件名确定与每个媒体文件对应 的加密后文件;
A4、 分片处理模块分别将每个加密后文件和对应媒体文件的关键帧索 弓 I文件存储在对应的文件夹中。
另外, 当媒体文件和加密后文件分別为多个时, 上述处理方法还包括 以下步骤:
分片处理模块在多个媒体文件中选择需要处理的选定媒体文件。
这一过程具体为:
B1、 分片处理模块获取多个媒体文件和多个加密后文件;
B2、 分片处理模块在多个媒体文件中选择要处理的选定媒体文件;
B3、 分片处理模块提取选定媒体文件的关键帧, 创建选定媒体文件的 选定关键帧索引文件, 根据文件名确定与选定媒体文件对应的选定加密后 文件;
B4、 分片处理模块将选定加密后文件和选定关键帧索引文件存储在对 应的文件夹中。
通过执行 B1-B4 , 使得分片处理模块可以根据用户的需要进行选择处 理, 功能更完善和人性化。
另外, 上述处理方法, 还可以包括:
分片处理模块在创建当前媒体文件的关键帧索引文件失败时, 跳过当 前媒体文件, 继续提取下一个媒体文件的关键帧, 创建下一个媒体文件的 关键帧索 31文件, 并显示当前媒体文件处理失败的提示消息。
上述处理方法, 还可以包括:
分片处理模块对加密后文件和关键帧索引文件进行后处理, 根据加密 后文件将关键帧索引文件的索引进行重新排序, 使流媒体服务器能在提供 加密后文件的快进快退响应时, 快速准确地查找加密后文件的关键帧。
以上所述是本发明的优选实施方式, 应当指出, 对于本技术领域的普 通技术人员来说, 在不脱离本发明所述原理的前提下, 还可以做出若干改 进和润饰, 这些改进和润饰也应视为本发明的保护范围。
