Quiz On Technical Aspects Of Broadcast Production!

The resolution refers to the number of dots or pixels in a given area. When the resolution is higher, it means that there are more dots or pixels packed into that area, resulting in a more detailed image. This is because a higher resolution allows for a greater level of precision and clarity in capturing and displaying visual information.

Widescreen has an aspect ratio of 16:9, which means that the width of the screen is 16 units and the height is 9 units. This aspect ratio is commonly used in modern televisions and computer monitors, as it provides a wider and more immersive viewing experience compared to the older standard aspect ratio of 4:3.

The correct answer is Digital Audio Broadcasting (DAB). DAB is a digital radio technology that allows for the transmission of audio signals in a digital format. It provides improved sound quality and a wider range of stations compared to traditional analog radio broadcasting. Digital Audio Broadcast (DAB) is not a correct acronym for this technology.

DVB stands for Digital Video Broadcasting. This term refers to the transmission of digital television signals over various mediums such as satellite, cable, or terrestrial networks. The DVB standard ensures efficient and high-quality delivery of audio, video, and data services to viewers.

MPEG stands for Motion Picture Experts Group. The term "experts" refers to a group of individuals who are knowledgeable and skilled in the field of motion picture technology and standards. The MPEG group is responsible for developing and maintaining standards for audio and video compression and transmission, which are widely used in the digital multimedia industry.

The correct answer is DVB-S. DVB-S stands for Digital Video Broadcasting - Satellite, which refers to the transmission of digital television signals via satellite. This technology allows for the delivery of high-quality video and audio content to viewers through satellite receivers. DVB-S is commonly used for direct-to-home broadcasting, where signals are received by individual satellite dishes installed at homes or businesses.

A standard frame has an aspect ratio of 4:3. This means that the width of the frame is 4 units and the height is 3 units. The aspect ratio is a ratio of the width to the height of the frame. In this case, the width is 4 units and the height is 3 units, so the aspect ratio is 4:3.

The frequency of power in the United Kingdom is 50Hz. This means that the alternating current in the electrical grid changes direction 50 times per second. The choice of 50Hz frequency is a standard used in many countries, including the UK, as it allows for efficient transmission and distribution of electricity.

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.

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.

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.

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.

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.

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.

PAL is higher in resolution than NTSC. The PAL system has a higher number of vertical lines, resulting in a higher overall resolution compared to the NTSC system. This higher resolution allows for a clearer and more detailed picture quality.

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.

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.

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.

Analogue television ceased broadcast in the UK in 2013. This means that after this year, analogue television signals were no longer transmitted, and viewers had to switch to digital television in order to continue watching TV.

NDE stands for Non-destructive Editing. This term refers to a method of editing digital files without permanently altering the original data. It allows for making changes to the file while preserving the integrity of the original content. This is particularly useful in fields such as photography or video editing, where it is essential to maintain the highest quality of the original file while making adjustments.
