products as below, users can consult and use it to learn about technology
that pertains to MicroVideoSoft products. |
ASF
Advanced Streaming Format (formerly Active Streaming Format).
A Microsoft file and data stream format for multimedia data
including audio, video, still images, and other data types.
Also referred to as Windows Media format..

AVI
AVI stands for Audio Video Interleave. This is a container video
format that specifies certain structure how the audio and video
streams should be stored within the file. AVI itself doesn't
specify how it should be encoded (just like the streaming format
ASF), so the audio/video can be stored in very various ways.
Most commonly used video codecs that use AVI structure are M-JPEG
and DivX. AVI contains code called FourCC which tells what codec
it is encoded with.

DVD
DVD stands for Digital Video Disc. A standard VCD records video
data in MPEG-1 format. On the other hand, a standard DVD records
video data in MPEG-2 format. A DVD player or a computer equipped
with a DVD drive is required to play DVDs. Almost all DVD players
also play VCDs.

SDK
A software development kit (SDK or "devkit") is typically a
set of development tools that allows a software engineer to
create applications for a certain software package, software
framework, hardware platform, computer system, video game console,
operating system, or similar platform. It may be something as
simple as an application programming interface in the form of
some files to interface to a particular programming language
or include sophisticated hardware to communicate with a certain
embedded system. Common tools include debugging aids and other
utilities often presented in an IDE. SDKs also frequently include
sample code and supporting technical notes or other supporting
documentation to help clarify points from the primary reference
material.

Video
Video is made up of an electro-magnetic signal that that can
travel through electronic devices like cables, antennas, satellite
dishes and TVs. Sent from its source, video has a certain amount
of information in it that makes up the video picture. However,
when that signal travels through a sending device it can also
pick up additional information from other electro-magnetic sources.
This is what is called interference or static (for those of
you who use bunny-ear antennas on your TV, you know what I mean).
What makes the difference between Analog and DV video is the
way the video signal is interpreted on the sending and receiving
ends of all that electro-magnetic communication.

WMA
WMA is acronym for Windows Media Audio. WMA files contain perceptually
encoded sound data. The frequencies that humans cannot perceive
are removed, although some audio purists say they can tell the
difference between a high bit-rate WMA and a Wave file.A WMA
file can be as much as 20 times smaller than an equivalent WAV
file.

MPEG
MPEG stands for 'Moving Pictures Experts Groups'. It is a group
working under the directives of the International Standards
Organization (ISO) and the International Electro-Technical Commission
(IEC). MPEG is a committee of experts from the audio, video
and computer industries developing an evolving series of standards
for compression of moving images.

SWF
SWF stands for 'Shockwave Flash'. It is a partially open file
format for multimedia and especially vector graphics developed
by Adobe (formerly Macromedia). Intended to be small enough
for publication on the web, SWF files can contain animations
or applets of varying degrees of interactivity and function.
SWF is also sometimes used for creating animated display graphics
and menus for DVD movies, and television commercials.
