To solve this question, the user needs to understand the concept of signalling methods and how information can be transmitted.

The correct answer is:

The Answer is: B - Two

Explanation:

Information can be transmitted via two signalling methods:

1. Analog Signalling: Analog signalling involves the transmission of information via continuous signals. An example of analog signalling is voice communication over the telephone.

2. Digital Signalling: Digital signalling involves the transmission of information via discrete signals. Digital signals can be transmitted using different techniques such as amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK). Digital signalling is used in computer networks, mobile phones, and other digital devices.

Options A, C, and D are incorrect because information can be transmitted via two signalling methods, not one, four, or five.

All options A-D are valid transmission media: wires (copper), coaxial cable, radio waves (wireless), and fiber optics. Since the question asks which is NOT an example, and all listed options ARE examples, 'None of the above' is the correct answer.

Air Crash Investigation (also known as Mayday) is showcased on National Geographic Channel, which is the correct answer. This documentary series investigates aviation accidents and incidents. While Discovery Channel airs similar content, this specific series is primarily associated with National Geographic.

Colors TV channel is a joint venture between Viacom (now ViacomCBS) and Network 18 Group in India. This partnership brought Viacom's content library to Indian television. Options A, B, and C incorrectly list other media companies.

C is correct because STAR in Star TV Network stands for 'Satellite Television Asian Region'. This accurately describes what the network is - a satellite television service for the Asian region. Option A uses 'Space' incorrectly, option B uses 'Telecast' instead of 'Television', and option D incorrectly uses 'Artic' instead of 'Asian'.

STAR TV stands for Satellite Television Asian Region. It was founded in 1990 and primarily serves Asian markets. The name reflects its satellite-based delivery technology and regional focus on Asia.

VSB (Vestigial Sideband) modulation is used for video transmission in TV broadcasting because it conserves bandwidth while maintaining picture quality. VSB removes one sideband almost completely and leaves a vestige (trace) of the other, making it more bandwidth-efficient than DSB or SSB for video signals.

Infrared (IR) propagation is used for remote controls because it's line-of-sight, low-power, and doesn't interfere with radio devices. IR signals are invisible to humans but reliably detected by receivers in TVs, AC units, and other appliances, making it ideal for short-range control.

The tendency of TV viewers to switch channels during advertisements is called 'surfing' or 'channel surfing'. The term emerged in the 1980s with the popularity of remote controls, making it easy to quickly browse through channels. 'Switching', 'jumping', and 'rolling' are not the standard terms used in media studies for this behavior.

IPTV stands for Internet Protocol Television, a system where television services are delivered through the internet using IP rather than traditional terrestrial, satellite, or cable formats. This technology enables digital TV services over broadband networks. The other options are fabricated or incorrect expansions.

Nielsen provides ratings for TV, radio, and books (through Nielsen BookScan), but does NOT provide ratings for fashion. Fashion is not one of the media or entertainment categories that Nielsen tracks with their ratings systems.

Nielsen primarily uses electronic measurement methods like People Meters and Set Meters for TV ratings, along with paper diaries (not 'dairy' - likely a typo) for some local markets. They do not collect data through letters from households, which would be impractical for real-time ratings.

Nielsen divides the US market into 210 DMAs (Designated Market Areas), which are geographic regions used for measuring television viewership and local media ratings. Each DMA represents a specific television market.

Nielsen collects TV ratings data through People Meters (electronic devices), Set Meters (attached to TVs), and Diaries (manual household logs). They don't use letters from households as a formal data collection method - this would be unreliable and non-standardized. Household letters are not a systematic ratings measurement methodology.

Vijay TV (now Star Vijay) was acquired by Star Network around 2001 and became one of the most popular Tamil entertainment channels. The other options are incorrect - Tamizhan TV, Pogo TV, and Win TV were not acquired by Star.
