XLD is an optical disc format developed by Theorysonic in collaboration with El TV Kadsre. It is a variant of designed to enhance some of the LD features and improve on its flaws. Unlike LaserDisc, it can deliver around 720 lines of video, with a higher quality video and audio than standard LaserDisc and added multi-channel support of 10 channels, 2 analog (stereo) and 8 digital, allowing for surround sound, dubs or commentary. The XLD-ROM, used in some Drillimation arcades, Theorysonic LaserPower and high-end UNIX workstations, has the size of 3 to 16GB. Theorysonic has also released a XLD/XLD-ROM external addon for TheoryDesks. Many XLD players have backwards compatibility with regular LaserDiscs and CDs and high-end ones even have a TVD drive underneath the XLD/LD/CD drive bay. The format was more popular in the El Kadsreian Islands and Japan than the rest of the world, with the exception of Norway and United Kingdom. Many of home video companies such as El TV Kadsre Home Entertainment and Viva Video, as well as labels like Naisuka Records began to distribute the format.
