Identify the correct sequence of the following TV transmission technologies in the order of their emergence.
(A) DTH, VHF, Cable, Satellite Cable
(B) Satellite cable, VHF, DTH, Cable
(C) Cable, VHF, Satellite Cable, DTH
(D) VHF, Cable, Satellite Cable, DTH
Correct Ans: (D)
Explanation:
Television transmission has evolved significantly over the years, with different technologies emerging to improve broadcast quality and accessibility. The correct sequence of TV transmission technologies in the order of their emergence is VHF → Cable → Satellite Cable → DTH.
Firstly, VHF (Very High Frequency) was among the earliest television transmission methods, delivering analog signals over limited distances. It allowed TV broadcasts to reach households but had restrictions in terms of quality and coverage.
Next, Cable TV emerged as a revolutionary step, providing better reception and a wider variety of channels through wired connections. This technology reduced signal interference and improved viewing experiences.
Following this, Satellite Cable introduced a new level of broadcasting by enabling direct transmissions from satellites to cable operators, enhancing coverage across larger areas. It ensured that even remote regions could access high-quality TV content.
Finally, DTH (Direct-to-Home) technology revolutionized television broadcasting by allowing users to receive satellite signals directly through dish antennas. This method provided superior picture and sound quality, along with an extensive range of channels.
In conclusion, TV transmission has continuously evolved to enhance viewing experiences. The shift from VHF to DTH reflects technological advancements that have shaped modern broadcasting.
