Hi8 (high-band Video8) is a consumer analog recording videocassette for camcorders based on the 8 mm video format developed by Sony, and introduced in 1989. The name is an improvement on the original Video8 format and mainly competed with Super-VHS.
==Overview== Hi8 uses improved recorder electronics and media formulation to increase the recorded bandwidth of the luminance signal. The FM carrier frequency range was increased from 4.2 to 5.4 MHz for regular Video8 (1.2 MHz bandwidth) to 5.7 to 7.7 MHz for Hi8 (2.0 MHz bandwidth). However, chroma signal bandwidth (color resolution) was not increased.
