Data sanitization

This article is originally from the IEEE Security and Privacy magazine, circa 2003. As such, some of the programs noted are out of date or obsolete. However, a number are still available and in use, and the basic concepts outlined are still valuable.

tv_remove_some_overlapping

TV_REMOVE_SOME_OVERLAPPING(1p)				User Contributed Perl Documentation			    TV_REMOVE_SOME_OVERLAPPING(1p)

NAME

       tv_remove_some_overlapping - Remove some overlapping programmes from XMLTV data.

SYNOPSIS

       tv_remove_some_overlapping [--help] [--output FILE] [FILE...]

DESCRIPTION

       Read one or more XMLTV files and write a file to standard ouput containing the same data, except that some 'magazine' programmes which seem
       to contain two or more other programmes are removed.

       For example, if 'Schools TV' runs from 10:00 to 12:00, and there are two programmes 'History' from 10:00 to 11:00 and 'Geography' from
       11:00 to 12:00 on the same channel, then 'Schools TV' could be removed.	A programme is removed only if there are two or more other
       programmes which partition its timeslot, which implies that it and these other programmes must have stop times specified.

       To avoid throwing away any real programmes, no programme will be discarded if it has content data other than title and URL.

       Filtering this tool won't remove all overlapping programmes but it will deal with the 'big magazine programme containing smaller
       programmes' data commonly seen from listings sources.

       --output FILE write to FILE rather than standard output
