Encrypted Video Coding	Principle	Standard	Encryption Mechanism
H.264/AVC with Selective Encryption	Encrypts sensitive parts (e.g., motion vectors) while keeping the rest unencrypted.	H.264, AVC	AES-based selective encryption of specific bitstream elements
HEVC with Format-Compliant Encryption	Encrypts specific parts while maintaining standard-compliant streams.	HEVC	Format-compliant encryption of motion vectors or syntax elements
Perceptual Video Encryption	Degrades video quality while preserving basic playability for privacy preservation.	H.264, HEVC	Partial encryption of frames or quantization degradation
Motion-Compensated Encryption	Encrypts motion vectors or residual data to prevent content reconstruction.	H.264, HEVC	AES encryption of motion vectors or residual data
