Slice groups for post-compression region of interest encryption in H.264/AVC and its scalable extension

作者：

Highlights：

• For medium and high bit rates, slice groups reduce drift with low overhead.

• The introduced all-grey base layer simplifies encryption by avoiding drift.

• Containing inter-layer drift can be reduced to containing temporal drift.
