Television channel

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.

YouTube

YouTube is a video-sharing website headquartered in San Bruno, California, United States. The service was created by three former PayPal employees in February 2005. In November 2006, it was bought by Google for US$1.65 billion. YouTube now operates as one of Google's subsidiaries. The site allows users to upload, view, rate, share and comment on videos, and it makes use of WebM, H.264/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated and corporate media video. Available content includes video clips, TV clips, music videos, movie trailers and other content such as video blogging, short original videos, and educational videos.

Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program. Unregistered users can watch videos, and registered users can upload videos to their channels. Videos considered to contain potentially offensive content are available only to registered users affirming themselves to be at least 18 years old.

Middle East

The Middle East (also called the Mid East) is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the derived noun is Middle-Easterner. Formerly, the Eurocentric synonym Near East (as opposed to Far East) was commonly used. Arabs, Azeris, Kurds, Persians, and Turks constitute the largest ethnic groups in the region by population, while Armenians, Assyrians, Circassians, Copts, Druze, Jews, Maronites, Somalis, and other ethnic and ethno-religious groups form significant minorities.

The History of the Middle East dates back to ancient times, with the (geo-political) importance of the region being recognized for millennia. Several major religions have their origins in the Middle East, including Judaism, Christianity, and Islam; the Baha'i faith, Mandaeism, Unitarian Druze, and numerous other belief systems were also established within the region. The Middle East generally has a hot, arid climate, with several major rivers providing irrigation to support agriculture in limited areas such as the Nile Delta in Egypt, the Tigris and Euphrates watersheds of Mesopotamia, and most of what is known as the Fertile Crescent. Most of the countries that border the Persian Gulf have vast reserves of crude oil, with the dictatorships of the Arabian Peninsula in particular benefiting from petroleum exports. In modern times the Middle East remains a strategically, economically, politically, culturally and religiously sensitive region.
