摘要：

Drift error is a critical issue in video scrambling which is widely used to protect privacy in surveillance video. However, how to improve video coding efficiency while preventing drift error in video scrambling has not been covered in most studies. Proposed is a prediction restricted scheme for H.264/AVC privacy protected video scrambling. Experiments show that the proposed scheme dramatically raises coding efficiency.
