Application program of scalable video information encryption device and method based on efficient video encryption

摘要

The device configured for encrypting video information includes a memory and a processor communicating with the memory. The storage unit is set to store the video information associated with the enhancement layer, which includes a first block and a second base layer, and the second base layer corresponds to the first block of the enhancement layer. The processor configuration is predicted by inter layer predictionThe first block in the expansion layer is based on the information derived from the second base layer. At least a part of the second block is located outside the reference area of the base layer, that is, the reference area, which can be used for interlayer prediction between the first block. The processor can encrypt or decode video information.
