Hello all,<br />
<br />
Please see my attempt to answer the following question:<br />
<br />
Q) Calculate the STORAGE REQUIRED (in megabytes) for a 10 minute QCIF<br />
video source assuming 4:2:0 format i.e. assume that the colour components<br />
are sub-sampled by a factor of 2 in each of the X (horizontal) and Y (vertical)<br />
directions. <br />
<br />
A) Assuming the following: 176 * 144 resolution, frame rate 8.33 Hz, 8 bits/pixel we would have:<br />
<br />
Luminance component : 176 * 144 * 8 * 8.33 = 1.7 MB<br />
Chrominance componet : (176 / 2) * (144 / 2) * 8 * 8.33 = 0.4MB<br />
<br />
Therefore total storage of approx 2.1MB required.

The Math / Science topic primarily includes discussions of mathematics, physics, statistics and economic analysis, but also biology, chemistry and other sciences.

Math / Science

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

Displays / Monitors

A digital camera or digicam is a camera that encodes digital images and videos digitally and stores them for later reproduction. Most cameras sold today are digital, and digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. Digital and film cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.  Digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing.
