Hello students Welcome To CSE Study247 , Today I discuss about Multimedia MCQs-5 , that contain 20 Multiple Choice Question With Answer.
Q.1 In Real Time Interactive Audio Video, a sequence number on each packet is required for?
Real-time traffic
Real-time playback
Real-time pixels
Real-time frames
Explanation
Sequence numbers are used in real-time traffic to reorder packets that arrive out of order and to detect packet loss during transmission.
Q.2 Multimedia is widely used to special— to movies?
Attachment
Control
Combination
Effects
Explanation
Multimedia tools and software are used to create computer-generated special effects (VFX) in the film industry.
Q.3 A heavy video in a WBT may not load because of poor?
Signal
KBPS
Frequency
Bandwidth
Explanation
Bandwidth refers to the maximum rate of data transfer; if it is low, high-definition (heavy) videos will fail to load or stream properly.
Q.4 —– Are typical examples of static images?
Photographs
File
Messages
None of these
Explanation
Static images are those that do not move; photographs are a primary example, unlike animations or video clips.
Q.5 Before audio or video signals can be sent on Internet, they need to be?
Channelized
Digitized
Organized
None of these
Explanation
Internet communication is digital; therefore, analog audio and video signals must be converted into digital format (digitized) to be transmitted.
Q.6 Most common compression technique that is used to create CD-quality audio is based on perceptual encoding technique is called?
Perceptual Encoding
Predictive Encoding
MPEG
None of these
Explanation
Perceptual encoding is a compression method that removes parts of the audio signal that the human ear cannot hear, maintaining high quality at lower bitrates.
Q.7 Streaming stored audio/video, files are compressed and stored on?
Internet
Domain
Website
Server
Explanation
In streaming services, compressed media files are hosted on a central server which then sends the data to the client’s device.
Q.8 For speech, we need to compress digitize signals at?
256 Khz
128 Khz
64 Khz
None
Explanation
64 Kbps (often related to a 64 Khz sampling context in legacy systems) is the standard bit rate for a digital speech channel using Pulse Code Modulation.
Q.9 Adobe photoshop is a?
Vector Graphics Editor
Raster Graphics Editor
Both A & B
None
Explanation
Adobe Photoshop is primarily a raster graphics editor, meaning it works with pixel-based images rather than mathematical paths.
Q.10 Paintshop pro was originally published as a?
Vector Graphics Editor
Raster Graphics Editor
Both A & B
None
Explanation
PaintShop Pro is a popular software used for editing raster (pixel) graphics, similar to Adobe Photoshop.
Q.11 Block size in block preparation step of JPEG compression is?
4 x 4
8 x 8
16 x 16
None of these
Explanation
JPEG compression divides an image into 8×8 pixel blocks before applying the Discrete Cosine Transform (DCT).
Q.12 In Virtual Reality environment, the experience is typically?
75% Real
75% Virtual
50% Virtual
None of these
Explanation
Virtual Reality (VR) aims to replace the real world; in certain academic classifications, it is defined as being 75% virtual to distinguish it from mixed reality.
Q.13 Which of the following statement is right according to AR (Augmented Reality)?
Completely immersive virtual environment
The system AR real world scene
Both A & B
None of these
Explanation
Unlike VR which is fully immersive, AR overlays or augments virtual information onto the real-world scene that the user is currently viewing.
Q.14 Morphing means?
Changing position
Changing shape
Changing color
None of these
Explanation
Morphing is a special effect in animation and film that changes one image or shape into another through a seamless transition.
Q.15 We can divide audio and video services into?
2 broad categories
3 broad categories
4 broad categories
None of these
Explanation
The three broad categories are: Streaming Stored Audio/Video, Streaming Live Audio/Video, and Interactive Audio/Video.
Q.16 AR is considered 25% virtual and 75% Real?
True
False
Both A & B
None of these
Explanation
Augmented Reality (AR) keeps the user grounded in the real world (75%) while adding small layers of virtual elements (25%).
Q.17 HTTP client accesses Web server by using the?
SEND message
GET message
AUTO receive message
None of these
Explanation
The ‘GET’ method is the standard HTTP request used by a client (browser) to retrieve data from a web server.
Q.18 VR is a?
Partially immersive
Fully immersive
Semi immersive
None of these
Explanation
Virtual Reality (VR) is characterized as fully immersive because it uses headsets to block out the physical world and replace it with a 360-degree digital environment.
Q.19 In Real Time Interactive Audio Video, to prevent jitter, we can time-stamp packets and separate arrival time from the?
Frame Time
Playback Time
Pixels Time
None of these
Explanation
By using timestamps, a playback buffer can ensure that packets are played at the correct ‘Playback Time’ even if they arrive with variable delays.
Q.20 In block coding, we divide our message into blocks, which are called?
Code blocks
Packet blocks
Datawords
None of these
Explanation
In data communication and block coding, the original message units are referred to as datawords, which are then mapped into codewords.
