1.1 is a electronic medium for the recording, copying, playback, broadcasting
and display of moving visual media.
2 kinds of video:
2.1 there are two types of video that are the digital and analog video.
2.1.1 the digital video: characterized by having
a discontinuous range of value,
2.1.2 the analog video: is characterized by
having a continuous range of value.
3 what are the diferrences between digital video and analog video:
3.1 There are 2 categories: Analog and Digital videos. The differences between Analog and Digital are that in
analog, information is translated into electric pulses of varying amplitude. In digital technology, translation
of information is into binary format (zero one) where each bit is representative of two distinct
4 4.What are the format of the digital video?
4.1 Digital video comprises a series of orthogonal bitmap digital
images displayed in rapid succession at a constant rate. In the
context of video these images are called frames. We
measure the rate at which frames are displayed in frames per
second (FPS). Since every frame is an orthogonal bitmap digital
image it comprises a raster of pixels. If it has a width of W
pixels and a height of H pixels we say that the frame size is
WxH. Pixels have only one property, their color. The color of a
pixel is represented by a fixed number of bits. The more bits
the more subtle variations of colors can be reproduced. This is
called the color depth (CD)of the video.
