broadcast quality video
(foldoc) | broadcast quality video
Roughly, video with more than
30 frames per second at a resolution of 800 x 640 pixels.
The quality of moving pictures and sound is determined by the
complete chain from camera to receiver. Relevant factors are
the colour temperature of the lighting, the balance of the
red, green and blue vision pick-up tubes to produce the
correct display colour temperature (which will be different)
and the gamma pre-correction to cancel the non-linear
characteristic of cathode-ray tubes in television receivers.
The resolution of the camera tube and video coding system
will determine the maximum number of pixels in the picture.
Different colour coding systems have different defects. The
NTSC system (National Television Systems Committee) can
produce hue errors. The PAL system (Phase Alternation by
Line) can produce saturation errors.
Television modulation systems are specified by ITU CCIR Report
624. Low-resolution systems have bandwidths of 4.2 MHz with
525 to 625 lines per frame as used in the Americas and Japan.
Medium resolution of 5 to 6.5 MHz with 625 lines is used in
Europe, Asia, Africa and Australasia. {High-Definition
Television} (HDTV) will require 8 MHz or more of bandwidth.
A medium resolution (5.5 MHz in UK) picture can be represented
by 572 lines of 402 pixels. Note the ratio of pixels to lines
is not the same as the aspect ratio. A VGA display (480n
lines of 640 pixels) could thus display 84% of the height of
one picture frame.
Most compression techniques reduce quality as they assume a
restricted range of detail and motion and discard details to
which the human eye is not sensitive.
Broadcast quality implies something better than amateur or
domestic video and therefore can't be retained on a domestic
video recorder. Broadcasts use quadriplex or U-matic
recorders.
The lowest frame rate used for commercial entertainment is the
24Hz of the 35mm cinema camera. When broadcast on a 50Hz
television system, the pictures are screened at 25Hz reducing
the running times by 4%. On a 60Hz system every five movie
frames are screened as six TV frames, still at the 4%
increased rate. The six frames are made by mixing adjacent
frames, with some degradation of the picture.
A computer system to meet international standard reproduction
would at least VGA resolution, an interlaced frame rate of
24Hz and 8 bits to represent the luminance (Y) component. For
a component display system using red, green and blue (RGB)
electron guns and phosphor dots each will require 7 bits.
Transmission and recording is different as various coding
schemes need less bits if other representations are used
instead of RGB. Broadcasts use YUV and compression can reduce
this to about 3.5 bits per pixel without perceptible
degradation. High-quality video and sound can be carried on a
34 Mbaud channel after being compressed with ADPCM and
variable length coding, potentially in real time.

compressed video
(foldoc) | video compression
compressed video
Compression of sequences of images. Video compression
algorithms use the fact that there are usually only small
changes from one "frame" to the next so they only need to
encode the starting frame and a sequence of differences
between frames. This is known as "inter-frame coding" or "3D
coding".
MPEG is a committee producing standards in this area and
also the name of their standard algorithm. H.261 is
another standard.

full-motion video, Online Media.

digital video disc

DVD
DVD-R
DVD-ROM
(DVD, formerly "Digital Video Disc") An optical
storage medium with improved capacity and bandwidth compared
with the Compact Disc. DVD, like CD, was initally marketed
for entertainment and later for computer users. [When was it
first available?]
A DVD can hold a full-length film with up to 133 minutes of
high quality video, in MPEG-2 format, and audio.
The first DVD drives for computers were read-only drives
("DVD-ROM"). These can store 4.7 GBytes - over seven times
the storage capacity of CD-ROM. DVD-ROM drives read existing
CD-ROMs and music CDs and are compatible with installed
sound and video boards. Additionally, the DVD-ROM drive can
read DVD films and modern computers can decode them in
software in real-time.
The DVD video standard was announced in November 1995.
Matshusita did much of the early development but Philips made
the first DVD player, which appeared in Japan in November
1996. In May 2004, Sony released the first dual-layer drive,
which increased the disc capacity to 8.5 GB. Double-sided,
dual-layer discs will eventually increase the capacity to 17
GB.
Write-once DVD-R ("recordable") drives record a 3.9GB DVD-R
disc that can be read on a DVD-ROM drive. Pioneer released
the first DVD-R drive on 1997-09-29.
By March 1997, Hitachi had released a rewritable DVD-RAM
drive (by false analogy with random-access memory). DVD-RAM
drives read and write to a 2.6 GB DVD-RAM disc, read and
write-once to a 3.9GB DVD-R disc, and read a 4.7 GB or 8.5 GB
DVD-ROM. Later, DVD-RAM discs could be read on DVD-R and
DVD-ROM drives.

full-motion video
(foldoc) | full-motion video
(FMV) Any kind of video that is theoretically
capable of changing the entire content on the screen fast
enough that the transitions are not obvious to the human eye,
i.e. about 24 times a second or more. In practise most {video
encoding} relies on the fact that in most video there is
relatively little change from one frame to the next. This
allows for compression of the video data.
The term is used, chiefly in computer games, in contrast to
techniques such as the use of sprites that move against a
more-or-less fixed background.

(Or "graphics card",

especially an IBM PC, containing the necessary {video

adapters vary in the resolution (number of pixels) and
number of colours they can display, and in the refresh rate
they support. These parameters are also limited by the
monitor to which the adapter is connected. A number of such
display standards, e.g. SVGA, have become common and
different software requires or supports different sets.
