VIDEO 8-HI FORMAT (IEC60B(Sec)191)
The high band version of Video 8 retains the same footprint on tape, with embedded track finding and following, and a down-converted chroma sub-carrier. Significantly higher luminance frequencies are recorded on tape with almost double the frequency deviation of Video 8, yielding increased resolution and reduced chrominance-luminance cross-talk. There are no longitudinal tracks but an option records time code on the helical tracks between the video and PCM audio data.
