Panasonic D5 48

"D-5 is a professional digital video format introduced by Panasonic in 1994. Like Sony’s D1 (8 bit), it is an uncompressed digital component system (10bit), but uses the same half-inch tapes as Panasonic’s digital composite D3 format. A 120 min D-3 tape will record 60 min in D-5/D-5 HD mode. D-5 standard definition decks can be retrofitted to record high definition with the use of an external HD input/output box. The HD deck conversion does not allow for any error correction that exists on standard definition recordings, as the full bandwidth of the tape is required for the HD recording. D-5 HD uses standard D-5 video tape cassettes to record HD material, using an intra-frame compression with a 4:1 ratio. D-5 HD supports the 1080 and the 1035 interlaced line standards at both 60 Hz and 59.94 Hz field rates, all 720 progressive line standards and the 1080 progressive line standard at 24, 25 and 30 frame rates. Four 48 kHz 20 bit PCM audio channels, or eight 48 kHz 24 bit channels, are also supported. D-5 runs at different data rates for different formats 323 Mbit/s (1080/59.94i/8CH, 720/59.94p/8CH, 480/59.94i/8CH). 319 Mbit/s (576/50i/8CH); 300bit/s (1080/59.94i/4CH);720/59.94p/4CH, 480/59.94i/4CH);258 Mbit/s (1080/23.98p/8CH, 1080/24p/8CH);269 Mbit/s (1080/50i/8CH, 1080/25p/8CH, 576/50i/8CH)"
