Production teams originally sent two tapes to the channels; a primary copy and a backup copy. However, due to the tight filming schedules, a 70-minute episode might arrive at the broadcasting station on seven separate tapes in ten-minute installments. It happens that while the episode is being broadcast, the crew would be still shooting the last minutes or cutting the rest of the episode. During the airing of the nineteenth episode of "Man from the Equator", screens countrywide went black for 10 minutes. Actor Kwon Sang-woo was openly complaining that he was still shooting "Queen of Ambition" 30 minutes before the last episode began airing. In South Korea, some production teams still do planning and scheduling manually, instead of using dedicated software.
