| This paper aims at high-definition Studio environment control video systemchannel quality and source quality, to meet the high definition Studio technologystandards and content needs. The research tools are multi-waveform, high-definitioncamera and broadcast-quality HD monitor. This article was previously publishedunder research methods is to use multiple formats waveform monitor, analysis ofstudio video system structure, measurement and adjustment of high-definition Studiochannel node parameters. Author's innovative use of diamonds and eye-diagramfunction, adjustment of the SDI physical layer, so that the output signals quality iseffectively controlled. This article uses high-definition waveform monitor andbroadcast-quality HD monitor, measure and adjusts the brightness of the HDTVcameras, chroma, black level, detail level, as well as gamma curve, the realization ofhigh-definition Studio source quality control to meet the demand for HDprogramming.The study analyzes Beijing Television 600㎡ high definition studio, anddiscussed the demand of one famous TV program--. Authorstudies through practice, particularly to the current lack of Studio program, includingthe impact of engineering defects channel quality and affect the quality of HD sources.This article uses waveform monitoring and gamut range monitoring, high-definitioncamera and adjust the parameters of creativity. Of these, black gamma and skin detailfunction is the first time in the Studio making process. Combined with theoreticalknowledge and national standards, measured studio during the node program quality,analysis, through science and waveform diagram data analysis, obtaining optimalresults. Practice has proved, this article on HDTV studio video system channeltransmission made improvements, so that the studio video system withstood a longtime recording and large scale live events. With source quality control methods, theprogram quality has been significantly improved. Practical effects of this project werethe high praise. |
