This video on Pensacola real estate property and homes for sale
made me wonder what is the history digital and internet video? I was
really curious about waterfront video ...anyway. Starting in the late
70s to the early 80s, several types of video production equipment-
such as time base correctors (TBC) and digital video effects (DVE)
units (two of the latter being the Ampex ADO, and the NEC DVE) were
introduced that operated by taking a standard analog video input and
digitizing it internally. This made it easier to either correct or
enhance the video signal, as in the case of a TBC, or to manipulate
and add effects to the video, in the case of a DVE unit. The digitized
and processed video from these units would then be converted back to
standard analog video.
Later on in the 1970s, manufacturers of professional video
broadcast equipment, such as Bosch, RCA, and Ampex developed prototype
digital videotape recorders in their research and development labs.
Bosch's machine used a modified 1" Type B transport, and recorded
an early form of CCIR 601 digital video. None of these machines from
these manufacturers were ever marketed commercially, however.
Digital video was first introduced commercially in 1986 with the
Sony D-1 format, which recorded an uncompressed standard definition
component video signal in digital form instead of the high-band analog
forms that had been commonplace until then. Due to the expense, D-1
was used primarily by large television networks. It would eventually
be replaced by cheaper systems using compressed data, most notably
Sony's Digital Beta cam, still heavily used as a field recording
format by professional television producers.
Consumer internet digital video first appeared in the form of
QuickTime, Apple Computer's architecture for time-based and streaming
data formats, which appeared in crude form around 1990. Initial
consumer-level content creation tools were crude, requiring an analog
video source to be digitized to a computer-readable format. While
low-quality at first, consumer digital video increased rapidly in
quality, first with the introduction of playback standards such as
MPEG-1 and MPEG-2 (adopted for use in television transmission and DVD
media), and then the introduction of the DV tape format allowing
recording direct to digital data and simplifying the editing process,
allowing non-linear editing systems to be deployed cheaply and widely
on desktop computers with no external playback/recording equipment
needed. The widespread adoption of digital video has also drastically
reduced the bandwidth needed for a high definition television signal
(with HDV and AVCHD, as well as several commercial variants such as
DVCPRO-HD, all using less bandwidth than a standard definition analog
signal) and Tapeless camcorders based on flash memory and often a
variant of MPEG-4.
