Binary, Greyscale, True colour, Red-green-blue (RGB)
Greyscale, True colour, Red-green-blue (RGB), Indexed
Binary, Greyscale, True colour, Red-green-blue (RGB)

- 5. Multiple Choice
Statements below are related to image quality. Which one is incorrect?
Resolution is number of pixels to represent a single image.
Colour Depth is number of colours per pixel which also represents number of colours supported.
Higher resolution image can represent picture with more detail or display in larger dimension.
Image size = resolution x colour depth
- 6. Multiple Choice
Digital audio quality can be increased by increasing the following:
Bits per sample
Sampling rate
Compression ratio
Number of channels
- 7. Multiple Choice
All the following statements are correct about video, except:
Video is captured and recorded as a sequence of images.
Each image captured from video is known as frame.
Digital video is recorded as ordered sequence of analogue still image or frame.
Recording and playback speed of video is measured in frame per second (fps).
- 8. Multiple Choice
Video compression is performed to reduce the size of stored video and data rate. Which of the following statement is correct?
Video stream can be compressed because it contains temporal redundancy that can use intra-frame compression.
Video stream can be compressed because it contains spatial redundancy that can use inter-frame compression.
MPEG-1 produces compressed data rate of 1.5 Mbps.
Compressed data rate of MPEG-2 format is 2-4 Mbps.
- 9. Multiple Choice
Below are three important technologies contribute towards the advancement of multimedia applications, except:
Knowledge-Based Intelligence Technology
Networking Technology
Coding and Compression Technology
Storage and Computation Technology
- 10. Multiple Choice
Below are the reasons we need compression, except:
Multimedia data is good in quality.
Limited network bandwidth.
Limited storage space.
Increasing resolution, sampling rate, more bits per pixel, will help improve media quality at the expense of increasing media size.
