T/AI 102-2018 AVS Interoperability Test Specification

Scope

Scope: This standard applies to the interoperability and compliance of AVS/AVS+/AVS2 encoders, transcoders, multiplexers, decoders, digital TV receivers, and other devices in the broadcasting and television field. Other types of equipment may refer to this standard for implementation. Main technical content: This standard specifies the technical requirements and evaluation methods for AVS interoperability testing. This standard replaces T/AVS 102-2015 "AVS Interoperability Test Specification". Compared with T/AVS 102-2015, the main technical changes are as follows: - New normative references have been added to the document, including "GB/T 33475.2-2016 Information Technology - High-Efficiency Multimedia Coding - Part 2: Video", "GB/T 33475.3-2018 Information Technology - High-Efficiency Multimedia Coding - Part 3: Audio", and "T/AVS 105-2017 AVS2 4K Ultra-High-Definition Encoder Technical Requirements and Measurement Methods" (see Chapter 2); - Abbreviations for AVS2, UDP, and UHDTV have been added (see 3.2); - IP input and output interfaces have been added to the interface requirements (see 5.2); - AVS2 video parameters have been added to the video parameter requirements (see Table 9); - Requirements for room-temperature load testing have been added (see 5.6) and the testing method for room-temperature load testing has been revised (see 6.7); - Appendix B has been modified to include scoring levels for overall image quality degradation, test result determination, and recording forms (see Appendix B).
