图 2示出了本发明移动终端视频播放的实现方法一具体实施例的处理 流程, 如图 2所示, 所述实施例包括下述步驟:
步驟 1 , 移动终端接收用户输入的开启近距无线连接请求, 开启自身的 近距无线连接功能;
其中, 移动终端的近距无线连接可以为蓝牙、 WIFI、 无线 USB等多种 方式。
步驟 2, 计算实体开启自身的近距无线连接;
本步驟中, 计算实体可以为计算机等计算功能强大的设备; 具体地, 当计算实体接收到用户输入的开启近距无线连接请求时, 则开启自身的近 距无线连接功能。
另外, 应当理解, 本步驟中计算实体是指: 位于移动终端近距无线连 接有效范围内的计算实体; 步驟 1和步驟 2在实现上是不区分先后顺序的。
步驟 3~4, 移动终端通过近距无线通信方式搜索临近区域的计算实体, 当搜索到计算实体时, 向所述计算实体发送无线连接请求;
具体地, 移动终端在自身的近距无线连接的有效范围内搜索计算实体; 当搜索到同样开启近距无线连接的计算实体时, 可以向该计算实体发送无 线连接请求。
步驟 5~6,计算实体对接收到的无线连接请求进行验证,当验证通过时, 返回同意接入信息给所述移动终端, 此时移动终端与计算实体之间的无线 连接建立完成;
具体地, 本步驟中, 所述计算实体对无线连接请求的验证还包括: 根 据自身的运行情况, 确定是否同意移动终端的接入请求, 当不同意时, 返 回不同意接入信息给所述移动终端;其中, 当计算实体的 CPU使用率较高、 运行进程数较多等情况时, 计算实体会返回不同意接入信息给所述移动终 端; 反之, 当计算实体的 CPU使用状态良好、运行进程数不太多的情况下, 计算实体会返回同意接入信息给所述移动终端。
步驟 7, 移动终端启动自身的远程视频连接模块,计算实体启动自身的 终端服务器模块, 移动终端和计算实体之间的远程视频连接建立;
具体地, 本步驟中, 移动终端首先启动远程视频连接模块的远程客户 端子模块, 所述远程客户端子模块可以采用虚拟化技术实现, 例如微软的 远程应用 (remoteApp )技术, 如此, 在移动终端远程登录计算实体时, 不 需要在移动终端上显示计算实体的桌面, 由此, 免去传输计算实体桌面图 像到移动终端所需要的大量显示数据, 实现更为简便; 然后启动远程视频 连接模块的传输适配任务子模块, 传输适配任务子模块接收远程客户端子 模块发来的数据, 建立与移动终端的无线任务模块的连接, 以完成与计算 实体的通信任务。
计算实体启动终端服务器模块, 进行分布式组件服务等相关环境的设 置, 将基于分布式实现的视频解码器作为一个组件共享给移动终端, 并作 为移动终端的视频解码器; 具体地, 添加所述移动终端到分布式组件服务 中, 同时在分布式组件服务中增加远程视频解码器, 此时, 移动终端的视 频解码器列表中显示有所述共享的视频解码器, 相应的, 所显示的视频解 码器可供移动终端共享使用。
步驟 8, 移动终端接收到用户输入的远程视频解码模式选择信息后, 启 用远程视频解码模式;
具体地, 本步驟中, 移动终端的视频解码器模块为用户提供视频解码 模式选择功能, 其包括本地视频解码模式和远程视频解码模式; 当移动终 端接收到远程视频解码模式选择信息时, 移动终端切换至远程视频解码模 式, 当进一步接收到用户根据移动终端提供的视频解码器列表输入的远程 视频解码选择信息时,停止数字信号处理器( Digital Signal Processor, DSP ) 软件任务、 切断自身 DSP与 CPU之间的数据通信; 同时, 为了节省移动终 端的功耗, 可以选择将所述 DSP置于休眠状态。
步驟 9~10, 移动终端启动虚拟协处理器任务模块,接收 CPU发来的待 解码的视频数据块和解码命令, 并启动远程视频解码任务模块, 将数据块 和解码命令緩沖后发送给远程视频解码任务模块, 由远程视频解码任务模 块将待解码的视频数据块通过远程视频解码器的分布式程序接口, 调用该 视频解码器进行解码等处理;
具体地, 移动终端启动虚拟协处理器任务模块后, 虚拟协处理器任务 模块可以连续接收 CPU发送来的待解码的视频数据块和解码命令, 进行緩 沖处理等事务后, 发送给远程视频解码任务模块; 同时移动终端启动远程 视频解码任务模块, 远程视频解码任务模块接收虚拟协处理任务模块发来 的数据块和解码命令, 并将该解码命令转换成远程调用命令; 具体地, 远 程视频解码任务模块将虚拟协处理器任务模块发来的解码命令, 转换成对 视频解码器的分布式程序接口的远程调用命令, 并将远程调用命令与虚拟 协处理器任务模块发来的视频数据块进行绑定并打包, 将数据包发送至传 输适配任务子模块; 传输适配任务子模块对接收到的数据包进行无线协议 数据格式转化后, 发送至无线任务模块, 由无线任务模块将所述数据发送 至计算实体。
步驟 11~12,计算实体自身的无线任务模块将接收到的数据发送至视频 解码器; 视频解码器进行本地解码, 并返回帧数据流给移动终端; 具体地, 本步驟中, 计算实体的无线任务模块对接收到的数据进行格 式转换, 得到包含待解码的视频数据块和解码命令的数据包, 并发送至视 频解码器; 视频解码器从数据包中提取解码命令和数据块, 根据计算实体 当前的解码设置, 最终利用计算实体的 CPU进行软件解码, 或利用计算实 体的显卡进行硬件解码, 并将解码得到的帧数据流返回给移动终端。
步驟 13 , 移动终端处理接收到的帧数据流, 并通过本地的视频播放器 进行播放;
具体地, 移动终端的无线任务模块将接收到的帧数据流发送至传输适 配任务子模块, 传输适配任务子模块将无线协议数据格式的帧数据流转化 为虚拟协处理器任务模块可处理的数据格式后, 将转化得到的帧数据流发 送至虚拟协处理器任务模块, 由虚拟协处理器任务模块对接收到的帧数据 流进行緩沖加速等处理后, 将最终得到的数据提供给移动终端的视频播放 器, 通过该视频播放器调用移动终端本地的液晶显示屏(LCD ) 等硬件进 行播放。
另外, 当移动终端的 CPU检测到步驟 7中建立的移动终端和计算实体 之间的远程视频连接断开时, 会将远程视频解码模式切换为本地视频解码 模式, 关闭虚拟协处理器任务模块、 远程客户端子模块、 远程视频解码任 务模块及传输适配任务子模块等, 并启动 DSP软件任务, 唤醒 DSP; 其中, 远程视频连接断开可以是接收到用户输入的终止远程视频解码模式的消 息、 或是检测到移动终端不在所述计算实体的服务范围内、 或是计算实体 终止为移动终端提供远程视频解码服务等情况造成。
