图 1 为本发明实施例将视频釆集设备接入次世代网络的装置结构示意 图; 以及 图 2 为本发明实施例将视频釆集设备接入次世代网络的方法实现流程 图。 本发明的较佳实施方式
本发明实施例将视频釆集设备接入次世代网络的装置的结构如图 1 所 示, 包括: 设置模块、 接收模块、 格式确定模块和转换模块; 其中,
设置模块,用于从视频釆集设备中读取该视频釆集设备支持的图像格式, 根据所读取到的图像格式设置该视频釆集设备的釆集图像格式; 并存储釆集 图像格式;
这里, 设置模块在初始化本发明所述装置和视频釆集设备时工作, 为视 频釆集设备设置釆集图像格式, 即设定视频釆集设备所釆集图像对应的图像 格式为所设置的釆集图像格式;
其中, 所述视频釆集设备为普通家用视频釆集设备, 以其可支持的图像 格式区分, 常见的普通家用视频釆集设备有以下几种类型: 可支持 XGA、 SVGA, VGA, CIF和 QVGA等的普通家用视频釆集设备, 可支持 SVGA、 VGA, CIF和 QVGA等的普通家用视频釆集设备、可支持 VGA、 CIF和 QVGA 等的普通家用视频釆集设备, 可支持 CIF的普通家用视频釆集设备和可支持 QVGA的普通家用视频釆集设备;

这里, 如果釆集图像格式对应的像素高于 SVGA对应的像素, 会增加视 频釆集设备的工作负担, 因此, 当所确定的像素高于 SVGA时, 将视频釆集 设备的釆集图像格式设置为 SVGA;
存储模块, 用于存储釆集图像格式。
其中, 所述釆集图像格式为: SVGA、 VGA, CIF或 QVGA。
所述转换模块包括: 第一转换模块和第二转换模块、 接入模块; 其中, 第一转换模块, 用于在所述格式确定模块所得到的图像格式为 SVGA、 VGA或 QVGA时, 获取接收到的图像, 并对图像进行差值运算, 得到像素 为接近目标格式的图像(如:接近 4CIF的 768*576、接近 720P的 1280*1152、 接近 1080P的 1920*1440 ) 的图像; 并裁剪所得到的像素为上述三种的图像 的宽度, 分别得到图像格式为 4CIF、 720P或 1080P的图像;
第二转换模块, 用于在所述格式确定模块所得到的图像格式为 CIF, 且 所述次世代网络支持的图像格式为 4CIF时, 获取接收到的图像, 并对图像进 行差值运算, 得到图像格式为 4CIF的图像; 或

步骤 205: 将所接收到的图像由对应的图像格式转换为次世代网络支持 的图像格式 , 并将转换得到的图像输出至次世代网络;
其中, 所述次世代网络支持的图像格式为 4CIF、 720P、 1080P。
这里, 所接收到图像对应的图像格式为 SVGA、 VGA或 QVGA时, 所 述将所接收到的图像由对应的图像格式转换为次世代网络支持的图像格式具 体为:
