In its stereoscopic 3D activities, 3ality produces as much as 10TB of data each day, which it archives to a Quantum Corp. tape robot with LTO-4 media. The studio recently produced the U2 3D film, which premiered at the Sundance Film Festival.

In addition to higher resolution digital formats, broadcasters need to repackage content into other forms: breaking news stories, videos of news events and Web content, which increases storage capacity needs. According to Jim Casabella, director of advanced technology at ABC Owned Television Stations Group in Burbank, CA, an average-sized television station has approximately 30 to 40 non-linear edit systems and 100 desktop edit clients. If that same television station broadcasts about 200 news stories a day, the capacity necessary for those news stories will be 30TB in SDTV and 120TB in HDTV (see "The post-production process," below).

Once production is done, archiving of the finished project is required, which adds to the need for more storage capacity, albeit of a different type. Casabella has spent the last three years on a project for digitizing and preserving the organization's legacy archives using an EMC Corp. Documentum system for archiving his legacy data.

"We share media files among 450 business units," says Casabella. "In our legacy archive, we have over 30 years' worth of content on tape, which has to be digitized over the next 10 years or be lost forever. ABC Owned Television Stations have about 7 million news stories to archive requiring about 2PB of storage. Disney [The Walt Disney Co., which owns the ABC Television Group] itself has around 6 million hours of video tape, requiring about 300PB of storage to archive."
