CBS Digital was initially using a Teranex system and Discreet's Inferno to restore footage from the series, working at 1080/24p resolution. Recently, the studio opted to switch to MTI Film's Correct digital mastering system to handle the restoration services. The Correct system takes a different approach than simply painting out scratches and defects. It uses a series of filters that allow the operator to draw a box or lasso around a defect, which then disappears.

CBS represents the first broadcast client for MTI Film (www.mtifilm.com).
