Zusammenfassung: | A method of disarming and reconstructing an encoded video stream to nullify malicious agents potentially embedded in the encoded video stream comprises decoding a received encoded video stream to obtain a decoded video stream, extracting, from the encoded video stream, encoding information calculated by an originating encoder to create the encoded video stream, adjusting the encoding information by replacing one or more quantization parameters defined in the encoding information with respective adjusted quantization parameter(s) calculated based on a random selection of a value from a range of quantization parameter values, encoding the decoded video stream using the adjusted encoding information to produce a modified encoded video stream and transmitting the modified encoded video stream.
一种消除和重构编码视频流以使潜在地嵌入在所述编码视频流中的恶意代理无效的方法,包括:对接收到的编码视频流进行解码以获得解码的视频流,从编码的视频流提取由发起编码器计算的用以创建编码的视频流的编码信息,通过用基于从量化参数值的范围中的随机选择值所计算的一个或多个相应的调整的量化参数替换在编码信息中定义的一个或多个量化参数来调整编码信息,使用调整的编码信息对解码的视频流进行编码以产生修改的编码的视频流,以及传输修改的编码的视频流。 |
