The video quality (approximately 3 MHz of luma bandwidth for CED [1]) was comparable to or better than a VHS-SP or Betamax-II video, but sub-par compared to LaserDisc (about 5 MHz of luma bandwidth). CED players were intended to be "low-cost" because they cost around half as much to manufacture as a VCR and had fewer precision parts. [ 18 ]
Video High Density (VHD) was an analog video disc format storing up to 60 minutes per side, predominantly marketed by JVC in Japan. In contrast to the optical LaserDisc format, the VHD format was read with a physical stylus. Facing numerous competing formats outside Japan, the reach of VHD remained very limited.
A LaserDisc player is a device designed to play video and audio (analog or digital) stored on LaserDisc.
