From A for AGF Videoforschung to Z for zapping, the most important technical terms in video research are explained here.
Audio matching is a technical method for measuring audiovisual content. In the AGF Panel with the UMX measurement system, it has been used in the panel households since 08/01/2012 to survey the television usage of panel members. Under the audio matching method, audio signals in the television set are captured in the form of audio patterns and continuously checked against programmes stored in a server. Matching signals are then assigned to a TV broadcaster. If content cannot be clearly assigned to a broadcaster (for example, if the programme is broadcast simultaneously on several channels), additional information such as the regional reception spectrum or infrared codes are used to make the assignment.Back to list
A kwa AGF Videoforschung hadi Z kwa zapping, maneno muhimu zaidi ya kiufundi katika utafiti wa video yanaelezwa hapa. Kuambatana kwa sauti ni njia ya kiufundi ya kupima maudhui ya sauti na kuona. Katika Jopo la AGF, mfumo wa kipimo cha UMX umekuwa ukitumiwa katika nyumba za jopo tangu tarehe 8 Januari 2012 ili kuchunguza matumizi ya televisheni ya wanachama wa jopo. Katika njia ya kulinganisha sauti, ishara za sauti katika televisheni zinapigwa kwa namna ya mifumo ya sauti na mara kwa mara kukaguliwa dhidi ya programu zilizohifadhiwa katika seva. Kisha ishara zinazolingana hutolewa kwa mtangazaji wa televisheni. Ikiwa maudhui hayawezi kupewa wazi kwa mtangazaji (kwa mfano, ikiwa programu hiyo inatangazwa wakati huo huo kwenye vituo kadhaa), habari za ziada kama vile wigo wa mapokezi ya kikanda au nambari za infrared hutumiwa kufanya mgawo.
