Systems and methods of motion detection on encrypted or scrambled video data streams are provided. Some methods can include identifying macroblock size information for an encrypted/scrambled video data stream and using the identified macroblock size information to determine a presence of motion in the encrypted/scrambled video data stream without decrypting and descrambling the encrypted/scrambled video data stream.

System and method of motion detection on encrypted or scrambled video data streams

Devices, methods, and systems for detecting motion in a high resolution video are described herein. One method includes dividing an image frame of a high resolution video into a number of blocks, determining whether motion is present in each of the blocks, and identifying, within each block in which motion is determined to be present, pixels in which motion is present.
