D-9 HD

A high definition digital component format based on D9. Records on 1/2-inch tape with 100 Mbps video.

For high definition video recording, JVC developed an extension to D-9 called D-9 HD, using twice the number of recording heads to record a 100 Mbit/s video bitstream at resolutions of 720p60, 1080i60 and 1080p24. This variant can also record 8 channels of PCM audio at 16 bits and 48 kHz. The higher data rate and increased tape speed mean that the recording time of any given cassette would be halved. D-9 HD, based on specifications, would have been higher quality than Sony HDCAM but lower than Sony HDCAM SR; no objective tests were made comparing these formats. It is not clear whether this proposed format was ever manufactured or sold.
