Table 3 Experimental scenarios of the JVCE under consistent set of parameters of video compression while varying several parameters of video encryption (Foreman video)
Scenario | 1 | 2 | 3 | Extended-1 |
|---|---|---|---|---|
Coefficient type | AC | DC | DCAC | AC |
Coefficient encryption | xor_enc | sign_enc & xor_enc | sign_enc | xor_enc |
Motion vector encryption | Â | One of all possible combinations | ||
Option for xor range | Â | Small | Small, large | |
Input video | Foreman video (QCIF format, 300 frames) | |||
Compression parameters | GOP : 30, QP : 25, Others : default | |||
