Co-sited Explanation: Deze zou ik onvertaald laten - een heel specifieke term uit de EXIF-specificatie over een vorm van sampling (het tegenovergestelde is centered/gecentreerd). http://www.tek.com/Measurement/App_Notes/25_15215/eng/25W_15... Een handige glossary met veel (technische) informatie over dit soort terminologie zegt het als volgt: Co-Sited Sampling – Co-sited sampling ensures that the luminance and the chrominance digital information is simultaneous, minimizing chroma/luma delay. This sampling technique is applied to color difference component video signals: Y, Cr, and Cb. The color difference signals, Cr and Cb, are sampled at a sub-multiple of Y, the luminance frequency – 4:2:2, for example. With co-sited sampling, the two color difference signals are sampled at the same instant, as well as one of the luminance samples. Co-Siting – Relates to SMPTE 125M component digital video, in which the luminance component (Y) is sampled four times for every two samples of the two chrominance components (Cb and Cr). Co-siting refers to delaying transmission of the Cr component to occur at the same time as the second sample of luminance data. This produces a sampling order as follows: Y1/Cb1, Y2/Cr1, Y3/Cr3, Y4/Cb3, and so on. Co-siting reduces required bus width from 30 bits to 20 bits. -------------------------------------------------- Note added at 1 hr (2007-10-03 08:20:08 GMT) -------------------------------------------------- Over de glossary: die blijkt uit drie delen te bestaan.
