We successfully implemented an OpenStack-based cloud system...thanks to Red Hat’s full support.

Do-Sub Shim, production facility office director, Broadcast Facility Department, KBS


Korean Broadcasting Station (KBS), one of Korea's largest broadcast media institutions, used to rely on outdated analog tapes to edit videos and add multilingual subtitles. By moving to a private OpenStack® cloud using Red Hat® Enterprise Linux® OpenStack Platform, KBS cut subtitling time for its broadcasts in half and now delivers programs to its worldwide viewers faster than ever.

The path to success

Challenge: Cut subtitling time for global broadcasts to a multilingual audience

The Internet lets broadcast programs reach audiences across the world, but viewers need accurate subtitles in their language to understand the content they watch. If subtitles aren't available or there are delays in releasing the latest subtitled programs, viewers will switch to another station. KBS relied on analog tapes to edit videos and add multilingual subtitles. As a result, viewers often had to wait 3 weeks to view content, risking KBS's position as a broadcast leader.

KBS improves productivity of broadcast systems with Red Hat

Solution: Transition from analog to digital with a private cloud

To replace its analog tapes with a faster, more efficient process, KBS upgraded to a digital, cloud-based system using Red Hat Enterprise Linux OpenStack Platform. Instead of using a complicated, lengthy workflow to produce analog tapes and send them off to be subtitled and reviewed, KBS now digitally subtitles multilingual content directly on video.

“We successfully implemented an OpenStack-based cloud system, which is still new and unfamiliar technology in Korea, thanks to Red Hat’s full support,” said Do-Sub Shim, production facility office director of the Broadcast Facility Department at KBS.

Results: Add subtitles faster and for less cost

By cutting the time it takes to add multilingual subtitles to its broadcasts in half, KBS now delivers programs to its worldwide viewers faster than ever, gaining a larger, more loyal audience for Korean programming. Instead of negotiating a tedious, time-consuming editing process, staff complete editing faster and focus on staying competitive in the rapidly changing broadcast environment. KBS has also significantly reduced labor costs, anticipating savings of more than ₩700 million (about US$618,842) annually and a 40% decrease in total cost of ownership (TCO) over 5 years.

Our initial deployment has been so successful that we are considering adopting Red Hat Enterprise Linux OpenStack Platform for other systems throughout KBS.
