Digital-S 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. Video quality is generally very high; at standard definition, D-9's quality is comparable with Digital Betacam. 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
