Blighty is a British English slang term for Britain, deriving from the Hindustani word vilāyatī (विलायती) (pronounced bilāti in many Indian dialects and languages), from Persian vilayet and ultimately from Arabic wilayah, originally meaning something like "province". In India the term came to refer to Europe, and more specifically Britain.

The term was more common in the latter days of the British Raj, and is now more commonly used as a term of endearment by the expatriate British community or those on holiday to refer to home.

In their 1886 Anglo-Indian dictionary, Hobson-Jobson, Sir Henry Yule and Arthur C. Burnell explained that the word came to be used in British India for several things the British had brought into the country, such as the tomato (bilayati baingan, whose literal translation is "foreign aubergine") and soda water, which was commonly called bilayati pani ("foreign water").

During World War I, "Dear Old Blighty" was a common sentimental reference, suggesting a longing for home by soldiers in the trenches. The term was particularly used by World War I poets such as Wilfred Owen and Siegfried Sassoon. During that war, a Blighty wound — a wound serious enough to require recuperation away from the trenches but not serious enough to kill or maim the victim—was hoped for by many, and sometimes self-inflicted.

A television channel is a physical or virtual channel over which a television station or television network is distributed. For example, in North America, "channel 2" refers to the broadcast or cable band of 54 to 60 MHz, with carrier frequencies of 55.25 MHz for NTSC analog video (VSB) and 59.75 MHz for analog audio (FM), or 55.31 MHz for digital ATSC (8VSB). Channels may be shared by many different television stations or cable-distributed channels depending on the location and service provider.

Depending on the multinational bandplan for a given region, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well. Channel numbering is also different. Digital television channels are the same for legacy reasons, however through multiplexing, each physical radio frequency (RF) channel can carry several digital subchannels. On satellites, each transponder normally carries one channel, however small, independent channels can be used on each transponder, with some loss of bandwidth due to the need for guard bands between unrelated transmissions. ISDB, used in Japan and Brazil, has a similar segmented mode.
