Content: Diepeveen built an error-correcting coder-decoder that was delivered in the summer of 1978. The decoder was included in the CD prototype player that was presented to the international press. To commemorate this breakthrough, Philips received an IEEE Milestone Award on March 6, 2009. This breakthrough was also appreciated by Sony and they started a cooperation with Philips that resulted in June 1980 in a common CD system standard. Philips as a whole took a turn for the worse and by the end of the 1980s bankruptcy seemed a very real possibility. Under research director Kees Bulthuis the position of long-term

Sony executive Norio Ohga, later CEO and chairman of Sony, and Heitaro Nakajima were convinced of the format's commercial potential and pushed further development despite widespread skepticism. As a result, in 1979, Sony and Philips set up a joint task force of engineers to design a new digital audio disc. Led by engineers Kees Schouhamer Immink and Toshitada Doi, the research pushed forward laser and optical disc technology. After a year of experimentation and discussion, the task force produced the "Red Book" CD-DA standard. First published in 1980, the standard was formally adopted by the

Content: on optical videodisc technology. In the interview by Tekla Perry for the IEEE Spectrum, May 2017, Immink explains that he got involved in the CD project at the end of 1979 when Sony and Philips had decided to jointly settle one design. Both Philips and Sony had shown prototype CD players to the press in 1978. The team at Philips, he says, "needed someone to do measurements of the two competing systems, the quality, how they coped with scratches, how they coped with imperfections of the disc. My job with the LaserDisc was finished, so I said, 'Sure, I could

Title: Magnavox
Content: read, 12 inch disc that would contain recorded video material. In the early 1980s, Philips worked with Sony to create a standard for optical audio discs (CDs), using the technology developed for the LaserDisc. Teamed with Sony, Philips used the Magnavox brand name to introduce the CD-DA standard and equipment for consumer audio with the Magnavox player sold in department stores while the Sony CDP-101 went to high-end audio stores. During the late 1970s the company released the Odyssey², also known as the Philips Videopac. In the early 1980s, Philips merged Sylvania, Philco and Magnavox into one division headquartered in

Title: CD player
Content: in 1970. Following litigation, Sony and Philips licensed Russell's patents (then held by a Canadian company, Optical Recording Corp.) in the 1980s. The Compact Disc is an evolution of LaserDisc technology, where a focused laser beam is used that enables the high information density required for high-quality digital audio signals. Prototypes were developed by Philips and Sony independently in the late 1970s. In 1979, Sony and Philips set up a joint task force of engineers to design a new digital audio disc. After a year of experimentation and discussion, the "Red Book" CD-DA standard was published in 1980. After their
