communicates with the end user's media player to determine
the optimum speed for delivery.
mono Mono is a single audio channel for lowest bitrate consumption.
MPEG Moving Picture Experts Group. A family of international
standards used for coding audio/video information into
digital format. Currently, MPEG-2 is the standard for digital
video formats and MP3 for strictly digital audio formats.
non-interlaced
video content
Describes video content within a given frame that does not
consist of distinct imagery data fields. (e.g. computer
monitors)
noise removal Removes video artifacts such as white noise from video
signals.
NTSC National Television Systems Committee. Is a standard format
adopted by the FCC for television broadcasts in the United
States, Japan, Canada, and Mexico. Specifications: 525 lines of
resolution per frame at 30 fps.; 60 Hz field frequency; requires
a 6 MHz analog channel for transmission.
PAL Phase Alteration Line. Is the standard format for television
broadcasts in Germany, Great Britain, South America,
Australia, and most of Western European and Asian countries.
PCM Pulse Code Modulation. Is a sampling technique for digitizing
analog signals, especially audio signals. PCM samples the
signal 8000 times a second; each sample is represented by 8 bits
for a total of 64 kbps. There are two standards for coding the
sample level. The Mu-Law standard is used in North America
and Japan while the A-Law standard is use in most other
countries.
resolution A synonym for sharpness in regards to imagery detail, it is
measured in lines or pixels.
sampling rate Sampling rate determines the sound frequency range
(corresponding to pitch), which can be represented in digital
waveform. The range of frequencies represented in a
waveform is often called its bandwidth.
saturation Is chromatic purity: freedom from dilution with white.
smoothing Smooths out image if you find video content is too fine and on
the grainy side.
