Digital Replay System (DRS) is a cross platform application developed at the University of Nottingham. It allows data analysts to interrogate large heterogeneous data sets by supporting a synchronised playback of multimedia file types. DRS acts as a data repository, organiser, synchroniser, and visualiser allowing for a very rich level of digital record support. DRS additionally supports annotation, transcription and coding and with its facilities for import/export it can be combined with packages such as SPSS to support a wide variety of analysis types. Finally, DRS is a powerful tool for the graphical representation and analysis of recorded system log data, allowing databases and textual logs to be easily explored and visualised, and crucially used in conjunction and synchrony with other types of recorded data.
