Video Hi8 (short for high-band Video8). First demonstrated in February 1989, it initially received approval from ten other manufacturers - Aiwa, Canon, Fuji, Hitachi, Konica, Matsushita, Maxell, Ricoh, Sanyo, and TDK - later joined by Nikon, Samsung, Sharp, and TEAC. Japanese companies produced camcorders for other brands, such as Fisher and Siemens.
Hi8 utilized improved recording electronics and media composition to increase the bandwidth of the recorded luminance signal.
All Hi8 equipment can record and play back standard 8mm video. The reverse is generally not true, although some later 8mm systems recognize and play Hi8 recordings.
