    "abstract": "The Communications Laboratory, of the Australian Department of Communications and the Arts, has commenced a protection ratio measurement programme as a necessary precursor to the possible future introduction of digital terrestrial television (dttv) services into Australia. Protection ratios are used in the planning of terrestrial television and radio services to reduce the likelihood of unacceptable interference to a wanted service from other signals generated in the same area, in neighbouring areas or, under certain circumstances, in quite distant locations.",
