Multimedia Quiz (V,U,T,X,W)

What is the key difference between multimedia and hypermedia?

• Multimedia involves only audio and video, while hypermedia includes only images and text

• Hypermedia is an extension of multimedia that incorporates interactivity and linking capabilities

• Multimedia can only be used for entertainment, whereas hypermedia is used for education

• Hypermedia is a static form of multimedia

In multimedia applications, which software tool is primarily used for vector graphics creation?

• Adobe Photoshop

• Adobe Illustrator

• Final Cut Pro

• VLC Media Player

What is the primary advantage of using the YUV color model in video processing?

• It requires less storage compared to RGB

• It enhances brightness levels

• It prevents aliasing in images

• It is only used in digital photography

In analog video, which of the following is responsible for synchronizing the display of frames?

• Refresh rate

• Frame rate

• Sampling rate

• Quantization

Which of the following is a key characteristic of a progressive scan in digital video?

• Displays each frame in two interlaced fields

• Uses alternating fields for frame display

• Displays the entire frame in a single pass

• Reduces frame rate significantly

Why is chroma subsampling commonly used in video compression?

• To improve color accuracy

• To reduce bandwidth and file size

• To enhance contrast ratios

• To eliminate motion blur

Which of the following compression techniques is NOT lossless?

• Run-Length Encoding (RLE)

• Huffman Coding

• JPEG Compression

• Arithmetic Coding

What is the primary principle behind Huffman coding?

• Assigning fixed-length codes to symbols

• Assigning shorter codes to frequently occurring symbols

• Replacing symbols with predefined dictionary values

• Dividing images into blocks for compression

What is the primary advantage of lossless compression algorithms?

• They reduce file size without any quality loss

• They achieve higher compression ratios than lossy methods

• They are faster than lossy compression methods

• They work only on grayscale images

What is the main reason Arithmetic Coding achieves higher compression efficiency compared to Huffman Coding?

• It assigns non-integer bit-length codes

• It replaces symbols with fixed-length codes

• It uses tree structures for encoding

• It ignores statistical frequency of symbols
