SONY D1 VIDEO TAPE CONVERSIONS IN OXFORD OXFORDSHIRE UK
D-1 or 4:2:2 Component Digital is a SMPTE digital recording video standard, introduced in 1986. It started as a Sony and Bosch - BTS product and was the first major professional digital video format.
D-1 or 4:2:2 D-1 (1986) was a major feat in real time, broadcast quality digital video recording. It stores uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format with 8 bits, along with PCM audio tracks as well as timecode on a 3/4 inch (19 mm) videocassette tape. The uncompressed component video used enormous bandwidth, 173 Mbit/sec (bit rate), for its time. The maximum record time on a D-1 tape is 94 minutes.
AMPLEX D-2 VIDEO TAPE CONVERSIONS IN OXFORD OXFORDSHIRE UK
D-2 is a professional digital videocassette format created by Ampex and introduced at the 1988 NAB (National Association of Broadcasters) convention as a composite video alternative to the component video D-1 format. Like D-1, D-2 stores uncompressed digital video on a tape cassette; however, it stores a composite video signal, rather than component video as with D-1. While component video is superior for advanced editing, especially when chroma key effects are used, composite video is more compatible with most existing analog facilities.
PANASONIC D-3 VIDEO TAPE TRANSFERS IN OXFORD
D-3 is an uncompressed composite digital video videocassette format invented at NHK, and introduced commercially by Panasonic in 1991 to compete with Ampex's D-2. It uses half-inch metal particle tape at 83.88 mm/s (compare to D-2's 19 mm and 131.7 mm/s). Like D-2, the composite video signal is sampled at four times the color subcarrier frequency, with eight bits per sample. Four channels of 48 kHz 1620 bit PCM audio, and other ancillary data, are inserted during the vertical blanking interval.
PANASONIC D-5 HD VIDEO TAPE TRANSFERS IN OXFORD
D-5 is a professional digital video format introduced by Panasonic in 1994. Like Sony's D-1 (8-bit), it is an uncompressed digital component system (10-bit), but uses the same half-inch tapes as Panasonic's digital composite D-3 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.
