Introduction

Interpretation of the core content of the standard

GA/T 2000.250-20XX standard establishes a code system for video coding formats dedicated to the public security system, and uses a 2-bit sequential code to standardize the identification of 8 mainstream coding formats:

Code	Coding format	Technical characteristics	Typical application scenarios
01	SVAC1.0	my country's independent standard, supporting intelligent analysis of metadata	Public security video surveillance network system
07	HEVC/H.265	50% compression rate improvement	4K/8K ultra-high-definition video storage

Key Technology Comparison

SVAC2.0 Technical Advantages

Compared with 01-SVAC1.0 version, 08-SVAC2.0 in the standard:

Support HDR/WCG wide color gamut video
Add digital watermark anti-tampering function
Decoding complexity reduced by 30%

Standard Evolution Background

This standard is mainly formulated to solve:

Different manufacturersSystem compatibility issues caused by inconsistent video encoding formats
Standardization of new intelligent encoding formats (such as AV1) is lagging behind
Format standardization requirements for video evidence in forensic identification

Implementation suggestions

The construction of public security information systems should:

New systems should give priority to SVAC2.0 encoding
Existing systems should achieve standard compatibility through transcoding middleware
Video analysis platforms need to support parallel decoding of multiple encoding formats
