Operation
HKCTV is operated through two separate yet complementary networks, namely the wireless Multipoint Microwave Distribution System coaxial network (MMDS) and the wireline Hybrid Fibre coaxial network (HFC). The combined networks serve 1.70 million viewers, which take up 95% of the local households.
MMDS is a programming broadcasted through specific transmitters throughout Hong Kong. Broadcast signals are released from the transmitters to various "dishes" which are located on the rooftops of buildings, and are further transmitted to customers' televisions through the in-built coaxial cable.
The hybrid fibre-coaxial network consists of a fibre optic backbone which forms the base of the whole broadcast centre. It develops into smaller "branches" and penetrates into different areas in Hong Kong along the MTR tunnels, ending in customers' homes through the coaxial cable that the MMDS uses. This network enables high capacity which allows HKCTV to house over 31 channels as well as other telecommunication services.

Famous quotes containing the word operation:
“It is critical vision alone which can mitigate the unimpeded operation of the automatic.”
—Marshall McLuhan (1911–1980)
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
“Waiting for the race to become official, he began to feel as if he had as much effect on the final outcome of the operation as a single piece of a jumbo jigsaw puzzle has to its predetermined final design. Only the addition of the missing fragments of the puzzle would reveal if the picture was as he guessed it would be.”
—Stanley Kubrick (b. 1928)
