2. If we ignore the audio data in a video file, a video file is just a collection of many individual frames (i.e., images). What is the main reason that a video file can achieve a much higher compression ratio than a file that contains a single image file?
a) Elaborate the frame types in video compression. b) Explain the Motion compensation technique in Video compression.
How much does the efficiency of one way of encoding differ from that of another approach? Which one is now being extensively depended upon, and why is that the case in this particular scenario?
MP3 encoding Explain in your own words what is meant by masking effects in acoustics and what role they play in MP3 compression.
Video compression techniques allow for the creation of several copies of a video with varying degrees of quality. To what end are you using this strategy?
A video frame displayed onscreen consists of many pixels, with eachpixel, or cell, representing one unit of video output. A videodisplay’s resolution is typically specified in horizontal and verticalpixels (such as 1920 3 1080), and the number of pixels onscreen issimply the product of these numbers (1920 3 1080 5 2,073,600 pixels).A pixel’s data content is one or more unsigned integers. For ablack-and-white display, each pixel is a single number (usuallybetween 0 and 255) representing the intensity of the color white.Color pixel data is typically represented as one or three unsignedintegers.When three numbers are used, the numbers are usually between 0 and255, and each number represents the inten- sity of a primary color(red, green, or blue). When a single number is used, it represents apredefined color selected from a table (palette) of colors.Motion video is displayed onscreen by copying frames rapidly to thevideo display controller. Because video images or frames require manybytes…
Which is NOT a characteristic of human hearing exploited in MP3 compression? The presence of a loud low frequency sound can make it difficult or impossible to hear a higher frequency sound occurring at the same time. The omnidirectional characteristic of low frequency sounds allows two low frequency channels to be combined, as with a home theater system that uses a single subwoofer speaker. O A single channel for sound above 5000 Hz is usually sufficient because it is difficult to perceive the directional source of higher frequencies. O Most people can't hear sounds below 20Hz.
