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.

Takeshi's Castle

Takeshi's Castle (風雲！たけし城, Fūun! Takeshi-jō, literally Showdown! Takeshi Castle) was a Japanese game show that aired between 1986 and 1990, on the Tokyo Broadcasting System. It featured the Japanese actor Takeshi Kitano (also known as Beat Takeshi) as a count who owns a castle and sets up difficult challenges for players (or a volunteer army) to get to him. The show has become a cult television hit around the world. A special live "revival" was broadcast on April 2, 2005, for TBS's 50th anniversary celebrations.

Original Takeshi's Castle

The original show involved between 100 and 142 contestants whom General Tani (Hayato Tani) "forced" into a series of physical challenges, eliminating many of the contestants. Each show finished with a "Final Showdown" in which Count Takeshi (Kitano) was faced by the remaining contestants. In early episodes they would storm the castle set itself in a short-range water gun assault. Later episodes introduced carts with paper rings, and eventually lasers and light-sensitive targets. If the contestant's gun penetrated the paper ring or hit the sensor on Takeshi's cart, against such weapons as a large water gun and a laser-armed plane, Takeshi's cart was deactivated, the castle was "taken" and the game "won". The player who stopped Takeshi won one million yen (which, at the time, was roughly equivalent to $8,000 US or £5,000 sterling). However, there were only nine winners during the show's run.
