초록

본 논문에서는 UHD(Ultra High Definition) 방송 표준 수신기 검증을 위한 시험 스트림 제작 방법을 제안한다. 제안하는 시험 스트림은 비디오/오디오 시험 스트림, 시스템/자막 시험 스트림으로 구성된다. 비디오/오디오 시험 스트림은 HEVC (High Efficiency Video Coding) 비디오 표준 및 Dolby AC(Audio Coding)-3와 DTS(Digital Theater System)-HD(High Definition) 오디오 표준 시험에 사용 가능하며, 시스템/자막 시험 스트림은 PSIP(Program and System Information Protocol)과 자막 (Closed caption) 표준 수신기 검증 및 시험에 사용 가능하다. 개발된 HEVC 비디오 표준 시험 스트림은 신택스를 검증하기 위한 표준적합 시험 스트림과 에러 동작 검증을 위한 에러 시험 스트림으로 구분하여 제작하였다.

This paper presents a generation method of test streams for verifying conformance of an UHD broadcasting receiver including decoders for video and audio as well as parsers for PSIP and closed caption data. The proposed test streams for video/audio signals can evaluate conformance of HEVC, AC-3 and DTS-HD standards. Especially, test streams for HEVC video compression standard can be used for testing syntax compliance and error resilience for a HEVC decoder. Moreover, the proposed test streams for system/program and closed caption can be applied for verifying parsers for PSIP and CEA-708 standards.
