Videotapes
These VHS / NTSC videotapes are convenient for use in the classroom or laboratory. All you need is a standard VHS videocassette player (VCP or VCR) and a television monitor.
Videodiscs
Each videodisc from JCE Software is a 12-in., single- or double-sided, CAV-type video laserdisc in NTSC format. Videodiscs may be operated from any CAV-type laserdisc player using a handheld remote control keypad or a barcode reader interfaced to the laserdisc player.
