The duration of the WAV (22.05khz, 16 bit) Danish radio broadcast files in the testbed is approximately 20 minutes to 10.5 hours. This means some recordings cover a number of shows. The mpeg-2 video with Danish TV broadcasts in the testbed dataset are approximately 20 minutes to 17 hours, containing a number of shows. The mpeg-1 video with Danish TV broadcasts in the testbed dataset are approximately 10 minutes to 16 hours, again containing a number of shows. The metadata of the files are Radio or TV Channel ID, start time and end time (part of file names). The SB also has the program listings in a different collection. The recording start and end times are however usually 'a few minutes early' (just before the top of the hour) and 'a few minutes late', e.g. from 2 minutes to 9 am till 3 minutes past 10 am. Also the programs do not always start precisely at the announced time\! It would be nice to link the program listings to exact timestamps in the audio and video files, as this would make it possible to cut out single programs automatically when requested.\\
