They are Videoplus numbers, see http://tallyho.bc.nu/~steve/videoplus.html They say nothing about when the adverts occur. In the UK, a coloured square appears in a corner of teletext page 888 (subtitles page) at the start and end of a block of adverts. In theory this could be used to remove the adverts from a recording.
