ISO and IEC have established related serial of standards, but it has not been paid enough attention inside China. This article summarized and selected some terminologies of color management for digital television based on our science and research projects, it contains more than 100 terminologies. We especially selected new terminologies appeared within recent years, as well as rare, unclearly defined and confusing items. We also proposed Chinese names for non-standard names. Every terminology is given its corresponding English name, then underneath each terminology, the first paragraph contains the definition and its associated standard if applicable, the other paragraphs are brief description, related data etc. We strive to use standardized description, accurate data, and hope it can provide references to standardize, manage and improve digital television picture＇s chroma performance.
