What is the frequency of power in the United Kingdom?
-
25Hz
-
30Hz
-
50Hz
-

Which of the following is not a broadcast standard?
-
PAL
-
NTSC
-
SECAM
-
MPEG
Correct Answer
A. MPEGExplanation
MPEG is not a broadcast standard. PAL, NTSC, and SECAM are all analog television broadcast standards used in different parts of the world. MPEG, on the other hand, is a compression format used for digital video and audio. It is commonly used for storing and transmitting video files, but it is not a standard for broadcasting television signals.Rate this question:

Which provides a clearer image?
-
Progressive
-
Interlaced
Correct Answer
A. ProgressiveExplanation
Progressive scanning provides a clearer image compared to interlaced scanning. In progressive scanning, the entire frame is displayed at once, with each line being displayed sequentially. This results in a smoother and more detailed image, as there is no flickering or visible scan lines. On the other hand, interlaced scanning displays only half of the lines at a time, alternating between odd and even lines. This can lead to visible scan lines and a less clear image, especially during fast motion or when viewing on larger screens.Rate this question:

What is the frequency of power in the United States?
-
25Hz
-
30Hz
-
50Hz
-
60Hz
Correct Answer
A. 60HzExplanation
The frequency of power in the United States is 60Hz. This means that the alternating current supplied to households and businesses in the US changes direction 60 times per second. The standard frequency of 60Hz is used in North America, Central America, and parts of South America, while other regions, such as Europe and Asia, typically use a frequency of 50Hz. The frequency of power is important as it determines the performance and compatibility of electrical devices and appliances.Rate this question:

Why is digital editing better than analogue editing?
-
Files remain in tact
-
Transfer is quicker
-
No data is lost in transfer
-
Digital transitions are easier to accomplish than analogue
-
All of the above
Correct Answer
A. All of the aboveExplanation
Digital editing is better than analogue editing because it offers several advantages. Firstly, files remain intact during the editing process, ensuring that the original data is preserved. Secondly, the transfer of digital files is quicker compared to analogue methods, saving time and increasing efficiency. Additionally, no data is lost during the transfer of digital files, ensuring that the quality and integrity of the content is maintained. Lastly, digital transitions are easier to accomplish than analogue transitions, providing more flexibility and creative possibilities.Rate this question:

Bluray uses a blue coloured laser because...
-
The disks look more exciting
-
You can make the data smaller and fit more on a disc
-
Red lasers are copyrighted by the CD/DVD format makers
-
All of the above
Correct Answer
A. You can make the data smaller and fit more on a discExplanation
The correct answer is "You can make the data smaller and fit more on a disc." Blu-ray uses a blue coloured laser because it has a shorter wavelength compared to red lasers used in CDs and DVDs. The shorter wavelength allows for more precise reading and writing of data, which enables the data to be stored in smaller pits on the disc. This, in turn, allows for higher data density and the ability to fit more information on a single disc.Rate this question:

Correct Answer
A. Kilobits per secondExplanation
kbps stands for kilobits per second. In this context, it refers to the rate at which data is transmitted in a DAB radio broadcast. Kilobits per second is a unit of measurement used to quantify the speed or rate of data transfer in digital systems. It indicates that 128,000 bits of data are transmitted every second in a DAB radio broadcast.Rate this question:

What is the framerate of PAL video?
-
24fps
-
25fps
-
27.9fps
-
29.97fps
Correct Answer
A. 25fpsExplanation
PAL video has a frame rate of 25fps. PAL (Phase Alternating Line) is a video standard used in Europe, Australia, and parts of Asia. It has a higher resolution and a slightly slower frame rate compared to the NTSC video standard used in North America and Japan. The frame rate of 25fps ensures smooth motion and is compatible with the power frequency of 50Hz in PAL regions.Rate this question:

How much more detail does 1080p provide than PAL.
-
2 times
-
3 times
-
4 times
-
6 times
Correct Answer
A. 4 timesExplanation
1080p provides four times more detail than PAL. This is because PAL has a resolution of 576i, which means it has 576 lines of interlaced resolution, while 1080p has a resolution of 1080 progressive lines. Therefore, the number of lines in 1080p is four times greater than in PAL, resulting in a much higher level of detail.Rate this question:

What is the framerate of NTSC video?
-
24fps
-
25fps
-
27.9fps
-
29.97fps
Correct Answer
A. 29.97fpsExplanation
NTSC (National Television System Committee) is a video standard used in North America and some other countries. The framerate of NTSC video is 29.97fps. This is a non-integer value because it was derived from the original black and white NTSC system, which operated at 30fps. However, to accommodate color information, the framerate was slightly reduced to 29.97fps. This framerate is commonly used for broadcast television and DVD video in NTSC regions.Rate this question:
