9. What about videos recorded from the television? • A broadcast program, but not a cablecast program, may be recorded off-air and retained by a non-profit educational institution for 45 days. After 45 days it must be destroyed. • Off-air recordings must be used once during the first 10 days by individual teachers in the course of relevant teaching activities, and repeated once if necessary. • Off-air recordings may not be regularly recorded in anticipation of requests. • All copies of off-air recordings must include the copyright notice on the broadcast program as recorded. • Excerpts may be used in class, but the programs may not be altered or electronically combined with other work.
