CBS Sports drafts Dalet for sports production

The CBS Sports division is using a DaletPlus NewsWire system from Dalet Digital Media Systems to manage scripts and rundowns for their most popular sports programs. The system was used for the Super Bowl and will again be put into operation for live coverage of the upcoming March Madness college basketball tournament.

The system's advanced rundown management includes comprehensive control over teleprompters and automatic live updates, with the ability to modify copy and on-air scripts on the fly.

When on the road covering events such as college basketball, the Dalet application enables network operators to work remotely on a wide area network (WAN), as well as quickly synchronize all their remote systems and the main server at CBS headquarters in New York. Keeping all the systems in sync offers the crew both backup security and streamlined production processes in the facility and onsite.
