Test stream generation for digital cable UHD broadcasting standard

摘要

This paper proposes a generation scheme of compliance test streams for verifying conformance of a digital cable UHD (Ultra High Definition) receiver including video and audio decoders as well as system and closed caption modules. The proposed test streams for video and audio decoders can test compliance with HEVC (High Efficiency Video Coding) standard and DTS(Digital Theater System)-HD(High Definition) specification. Especially, HEVC test steams include syntax compliance and error resilience test streams for HEVC video compression standard. Moreover, the proposed test streams for system and closed caption modules can be used for verifying parsers for PSIP (Program and System Information Protocol) and closed caption.
