D-9 or Digital-S
Digital-S
as it was originally known, is a professional digital video videocassette format created by JVC
JVC
in 1995. It is a direct competitor to Sony's Digital Betacam. Its name was changed to D-9 in 1999 by the SMPTE.[1] It was used to a small extent in Europe and Asia and saw some use in the US, notably by the Fox news channel,[2] but was a commercial failure compared with Digital Betacam. It was superseded by high definition tapeless formats.

Technical details[edit] D-9 uses a tape shell of the VHS
VHS
form factor, but the tape itself uses a much higher quality metal particle formulation. The recording system is digital and for video uses DV compression at a 50 Mbit/s bitrate. Video

is recorded in 4:2:2 component format at a variety of standard definition resolutions, in either 4:3 or 16:9 aspect ratios. Audio is recorded as 16-bit/48 kHz pcm with up to four separate channels.[3] Video
Video
quality is generally very high; at standard definition, D-9's quality is comparable with Digital Betacam.[4] HD recording[edit] For high definition video recording, JVC
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.[5] D-9 HD, based on specifications, would have been higher quality than Sony

SR; no objective tests were made comparing these formats. It is not clear whether this proposed format was ever manufactured or sold.[6] Additional information[edit] Although D-9 uses the same video codec (DV) as MiniDV, the video bitrate of D-9 is significantly higher than that of the "prosumer" format. DVCPRO
DVCPRO
achieves bitrate parity with D-9 and D-9 HD, but has a slower tape speed, making it less reliable. Some of the D-9 television studio gear is capable of recording with Sel-Sync or pre-read and is provided with four-channel audio like Digital Betacam. Serial digital interfaces (SDI) are also provided. A dockable recorder, the JVC BR-D40, attached to a variety of cameras, and there was a one-piece camcorder, the JVC
