Low delay content disarm and reconstruction (CDR) of live streaming video

Abstract:

A method of disarming and reconstructing an encoded video stream to nullify malicious agents potentially embedded in the encoded video stream comprising 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.
