一种视频水印嵌入的方法及条件接收模块
摘要：
本发明实施例公开了一种视频水印嵌入的方法及条件接收模块，无需对压缩视频流进行编解码操作，减少计算量，提高视频图像的质量。本发明实施例包括：从传输流中提取某一时间段的压缩视频流；生成预置规格的视频水印；在压缩视频流中，确定出满足预置规格的视频帧，将压缩视频流中的视频帧替换成所述视频水印；或者，在压缩视频流中，确定出满足预置规格的视频场，将压缩视频流中的视频场替换成视频水印。
摘要（英）：

The embodiment of the invention discloses a video watermark embedding method and a condition receiving module. The encoding and decoding operation on compressed video streams is not needed, the calculation amount is reduced, and the video image quality is improved. The method disclosed by the embodiment of the invention comprises the steps that compressed video streams in a certain time period are extracted from a transmission stream; video watermarks in preset specifications are generated; in the compressed video streams, video frames meeting the preset specifications are determined, and the video frames in the compressed video streams are replaced into the video watermarks; or in the compressed video streams, video fields meeting the preset specifications are determined, and the video fields in the compressed video streams are replaced into the video watermarks.
