From A for AGF Videoforschung to Z for zapping, the most important technical terms in video research are explained here.
The 0/1 method is one of two processing methods which the user can select for special analyses in the AGF evaluation software. Under this method, performance values are calculated independently of the viewing duration. When a usage occurs, the p-value is set to 1. Thus, the full weight of a person is always included in the analysis. A prefilter can be integrated that limits the groups of persons to 60-second consecutive viewers.
4G describes the fourth generation of mobile networks. Predecessors of the fourth generation include the first to third generation of mobile networks: 1G, 2G and 3G. While the 1G networks were still equipped with analogue transmission technology and only enabled simple telephone connections, 2G networks with digital transmission enable higher quality telephone connections at lower costs and the transmission of SMS messages. 3G (UMTS) was switched off in Germany in 2021. The fourth-generation networks are IP-based and enable high-speed data transmissions at any time and any place. The most widespread standard for 4G is LTE.
The newest generation of mobile networks allows for transmission speeds of up to 10 Gbit/s. 5G networks are currently being built out in Germany.
