(For details on each episode's original airdate, see List of Star Trek: The Original Series episodes.) Leonard Nimoy hosted a second run from December 28, 1998 to March 24, 1999, but not all the episodes were broadcast because the show was abruptly cancelled before completion. Remastered edition In September 2006, CBS Domestic Television (now known as CBS Media Ventures, the current rights holders for the Star Trek television franchises) began syndication of an enhanced version of Star Trek: The Original Series in high definition with new CGI visual effects. Under the direction of Star Trek producer David Rossi, who consulted with Mike and Denise Okuda, the visual and special effects were recreated to give Star Trek: The Original Series a more modern look. Special attention was given to such elements as the Enterprise, alien planets and their images depicted from space, planets seen from orbit, alien spacecraft, and technology such as computer readouts, viewscreen images, and phaser beams. The restoration and enhancement was performed by CBS Digital. All live-action footage was scanned in high definition from its first-generation 35 mm film elements. While it was possible to retouch and remaster some visual effects, all new exterior ship, space, and planet shots were recreated under the supervision of Niel Wray, a recent visual-effects Emmy nominee. As noted in the "making of" DVD feature, first-generation "original camera negatives" were used for all live-action footage, but not for external shots of the ship and planets. Notable changes include new space shots with a CGI Enterprise, and other new models (for example, a Gorn ship is shown in "Arena"), redone matte background shots, and other minor touches such as tidying up viewscreens. A small number of scenes were also recomposed, and sometimes new actors were placed into the background of shots. The opening theme music was also re-recorded in digital stereo. The first episode to be released to syndication was "Balance of Terror" on the weekend of September 16, 2006. Episodes were released at the rate of about one a week and broadcast in a 4:3 aspect ratio. Despite the HD remastering, CBS chose to deliver the broadcast syndication package in Standard Definition (SD TV). The HD format was made commercially available through Blu-ray, or by streaming and download such as iTunes, Netflix, and Xbox Live. While the CGI shots were mastered in a 16:9 aspect ratio for future applications, they were initially broadcast
