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.

Guy Ritchie

Guy Stuart Ritchie (born 10 September 1968) is an English filmmaker known for his crime films. He left secondary school and got entry-level jobs in the film industry in the mid-1990s. He eventually graduated to directing commercials. He directed his first film in 1995, a 20-minute short which impressed investors who backed his first feature film, the crime comedy Lock, Stock and Two Smoking Barrels (1998). He then directed another crime comedy, Snatch (2000). His next two films, the romantic comedy Swept Away (2002) and the crime drama Revolver (2005) were not commercial or critical successes. The next crime drama, RocknRolla (2008), received mixed reviews and a modest box office return. In 2009, he directed his first films in the action mystery genre, with Sherlock Holmes (2009) and its sequel Sherlock Holmes: A Game of Shadows (2011). Both films were major box office successes, and the two films received positive, and moderately positive reviews, respectively.

Early life

Ritchie was born in Hatfield, Hertfordshire, the second of two children of Amber (née Parkinson) and Captain John Vivian Ritchie (b. 1928), former Seaforth Highlanders serviceman and advertising executive. John's father was Major Stewart Ritchie, who died in France, in 1940, during World War II. John's mother was Doris Margaretta McLaughlin (b. 1896), daughter of Vivian Guy McLaughlin (b. 1865) and Edith Martineau (b. 1866), this last by whom she shares close common ancestors with Catherine, Duchess of Cambridge. The McLaughlins have a pedigree going back to King Edward I of England. Ritchie's mother, Amber, later married a baronet. His father's second marriage was to Shireen Ritchie, Baroness Ritchie of Brompton, a former model and later Conservative politician and life peer.
