Cinema Digital Sound

Background
Cinema Digital Sound was the first digital sound format, developed by Eastman Kodak and Optical Radiation Corporation. Its shortcomings, including lack of an analog backup in case of the digital soundtrack's failure, led to its early demise.

Only logo (June 15, 1990-July 10, 1992)


Logo: All that's known of this logo is the few frames with a black background with a black/lavender gradient stripe with white text reading "Cinema Digital Sound" in it. Above is "The Following Presentation Will Surround You In", and below is "Six Discrete Channels Of Crystal Clear Digital Sound".

FX/SFX: Unknown.

Music/Sounds: Unknown.

Availability: Extinct. The only solid evidence of this logo's existence is a picture of a human hand holding in it a 70mm strip with a few frames visible and light reflecting off of the strip. It appeared before screenings of CDS-encoded films. It may still exist in the hands of private collectors.
