下面结合附图及移动终端的手机电视业务的实施例对本发明技术方案 作进一步详细说明。
图 2是本发明提供手机电视节目截图的移动终端实施例的结构示意图, 此时, 流媒体接收单元就是手机电视节目接收单元 201、 流媒体播放单元就 是手机电视节目播放单元 202, 如图 2所示, 包括截图控制单元 200, 以及 分别与截图控制单元相连的手机电视节目播放单元 201、 操作控制器 203、 图片格式转换器 204和存储单元 205 ,以及与手机电视节目播放单元 201相 连的手机电视节目接收单元 202, 其中, 图片格式转换器 204还与存储单元 205相连。 下面详细介绍各单元的功能。
手机电视节目接收单元 202, 用于按照现有技术接收手机电视节目, 并 将接收的手机电视节目发送到手机电视节目播放单元 201 ;
手机电视节目播放单元 201 , 用于按照现有技术播放手机电视节目, 以 及显示手机电视节目的截图;
截图控制单元 200, 用于接收来自操作控制器 203的截图指令,从手机 电视节目播放单元 201 中读取当前所播放的手机电视节目的图像帧, 将该 图像帧发送到图片格式转换器 204;
操作控制器 203 , 用于接收用户发起的截图指令, 并将接收到的截图指 令发送到所述截图控制单元, 以触发截图控制单元 200执行实时截图操作, 其中, 操作控制器 203接收的截图指令可以是按键或者点击触摸屏某指定 区域的动作;

存储单元 205 , 用于来自存储图片格式转换器 204的图片信息。存储单 元 205可以是移动终端中临时存储文件的单元, 也可以是用户事先指定的 存储位置, 以供用户后续的使用, 比如在用户需要显示截图时, 由截图控 制单元 200读取该存储单元 205 中的图片信息即可。 本实施例中, 存储单 元 205进一步包括内存储器和 TF卡等外接存储器。
优选的, 存储单元 205进一步分为緩存区和存储区, 其中, 緩存区可 以是移动终端的 SDRAM。此时,截图控制单元 200读取当前所播放的手机 电视节目的图像帧后, 先将该图像帧緩存到终端的 SDRAM 中, 并提示用 户是否进行所述截图操作, 当接收到所述用户发送的确认截图操作的指令 时, 截图控制单元 200控制图片格式转换器 204读取并转换 SDRAM中緩 存的图像帧, 图片格式转换器 204将转换后的图片信息保存到终端用户事 先指定的路径下, 当截图控制单元 200接收到所述用户发送的取消截图操 作的指令或者未在设定时间内收到用户发送的确认截图操作的指令时,均认 为当前的截图操作有误, 及时将 SDRAM 中的緩存的图像帧删除释放掉, 以节约终端资源。
图 3是图 2所示移动终端实现手机电视节目截图的流程图, 如图 3所 示, 包括以下步骤:
步骤 301 : 启动手机电视功能及启动截图功能。
在步骤中, 可以是在启动手机电视功能的同时启动截图功能, 也可以 在启动手机电视功能之前, 提前激活截图功能, 还可以是在移动终端开启 手机电视功能之后再启动截图功能。
步骤 302: 在移动终端实时接收并播放手机电视功能的过程中, 判断是 否收到用户的截图指令, 如果是, 进入步骤 303 , 否则, 重复执行步骤 302。
本步骤中, 截图指令可以通过用户按下截图按键, 用户或点击触摸屏 预先设定区域来实现。
步骤 303: 移动终端读取当前手机电视节目正在显示的图像帧并保存。 步骤 304:移动终端将保存的图像帧转换为自身可读取的图片格式并存 储。
优选地, 在步骤 303 中, 移动终端读取当前手机电视节目正在显示的 图像帧后, 先緩存该图像帧, 再向用户再次确认是否进行截图操作, 如果 通过用户的确认, 保证操作无误, 则继续执行步骤 304并将转换后的图片 保存到指定路径下; 如果未通过用户确认, 即用户误操作, 则及时的将緩 存的图像帧删除, 以释放终端资源。 这里, 为了不影响用户收看手机电视 节目, 在移动终端向用户确认截图操作的过程中, 可以在移动终端进行手 机电视节目正常播放时, 以画中画的形式向用户提供截图的预览, 这样, 用户就可以通过预览来确认保存或删除当前预览的图片。 进一步地, 移动 终端可以每次向用户提供多图预览, 方便用户保存需要的截图图片。
当然, 上述流程也可以应用于除手机外的其他移动快捷式终端设备中。 从上述实施例可以看出, 本发明技术方案所提供的截图的方法筒单, 可操作性强, 而且, 由于本发明采用后台处理截图及保存操作, 保证了用 户继续正常观看电视节目。 另外, 本发明技术方案不仅仅限于观看手机电 视时实现图画的截取, 还可以适用于手机或其它终端上播放流媒体视频时, 进行快捷的抓图操作。
当然, 本发明还可以有其他多种实施例, 在不背离本发明精神及其实 变形, 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范 围。
例如, 用户使用多媒体终端进行在线流媒体收看时, 也可以通过发送 截图指令(比如用户按下设定的按键或点击触摸屏指定区域), 在继续正常 播放流媒体视频节目的同时, 多媒体终端后台执行视频节目画面的实时截 取及存储(比如可以存储到终端内置的存储器和 /或外接存储器中), 从而 满足终端用户对流媒体视频实时截图的需要。 其步骤大概如下: 启动流媒 体视频节目播放并启动截图功能; 在收看流媒体视频节目的同时, 进行实 时截图操作; 多媒体终端后台读取当前节目显示的图像帧并保存; 多媒体 终端将保存的图像帧转换为自身可读取的图片格式并保存。
