WOWOW chooses SGI for full HD broadcasting system
Louise Duffy ©RapidTVNews | 14-12-2011 Japanese pay-TV broadcaster WOWOW has selected and integrated a content server from SGI that is forming the core of a full HD file-based programme broadcasting infrastructure system.
WOWOW is the first pay TV broadcaster in Japan to switch over to an entirely file-based programme broadcasting infrastructure system, and offers three full HD channels.
The overall programme broadcasting infrastructure system was developed jointly by SGI and Toshiba Corporation. Software products independently developed by SGI Japan are used on 16 SGI(R) Rackable standard-depth servers to import and search content, as well as to perform subtitle registration. SGI Japan also custom-designed the unique configuration of the content servers, which store the programme data used in the broadcasting system. The programmes, commercials, and other content, converted to file format, are stored with redundancy in a system capable of holding up to 5,000 hours of content, making it the largest capacity system of its kind in the Asia-Pacific region.
Hirohisa Tanabe, chief engineer in the Master Control and Transmission Department Engineering Division at WOWOW, said: "In conjunction with the start of operation of three full HD channels, WOWOW began considering broadcasting equipment updates as long ago as 2006.
"Based on industry trends, we decided to switch to a file-based programme broadcasting system. We have been receiving co-operation from SGI Japan since the initial stage of considering the switch to a file-based system, and have obtained satisfying results through SGI Japan's exemplary system integration. In the end, we are aiming to use an entirely file-based system for all programme data handled by the channel."
