Sony's D1 format was the first major professional digital video format, introduced in 1987.
D1 stored uncompressed digitized component video, encoded at YUV 4:2:2 using the CCIR 601 raster format, along with PCM audio tracks as well as timecode. Uncompressed component video uses enormous bandwidth, and a simpler D2 system soon followed.
It used a 19mm (3/4") cassette tape format, and also stores PCM audio tracks as well as timecode.
D1 was notoriously expensive and the equipment required very large infrastructure changes in facilities which upgraded to this format. Early D1 operations were plagued with difficulties, though the format quickly stabilized and was renowned for its superlative image quality.
D1 is still in some usage as of 2003, and many of the technologies introduced with this format are still common to more recent digital videotape formats.
Panasonic's D5 format has similar specifications, but was introduced much later.
D1 creates leading edge technology products for the world market.
The PoP device is also simple to install, plugging in as a peripheral to the user's home computer.
We have a very diverse range of ground breaking products which includes a network attached disk imaging device, an integrated home media centre and the PoP device – the world’s most advanced and secure internet payment system.
