World Channel
WORLD Channel, also branded as WORLD, is an American digital multicast public television network owned and operated by the WGBH Educational Foundation. It is distributed by American Public Television and the National Educational Telecommunications Association and features programming covering topics such as science, nature, news, and public affairs. Programming is supplied by the entities, as well as other partners such as WNET and WGBH. It is primarily carried on the digital subchannels of PBS member stations. Background In 2004, the John S. and James L. Knight Foundation granted PBS funds to develop a public affairs network, Public Square, given the change in broadcasting to digital thus allowing stations to broadcast multiple channels. (Public Square was also a name previous given to a proposed civic series in early 2000s.) The Knight Foundation announced a challenge grant to PBS to launch this network on December 14, 2004 at the Digital Futures Initiative Summit. PBS would ...

Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

480p
480p is the shorthand name for a family of video display resolutions. The p stands for progressive scan, i.e. non-interlaced. The ''480'' denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio ( 640) or a horizontal resolution of 854 or less (848 should be used for mod16 compatibility) pixels for an approximate 16:9 aspect ratio ( 853.). Since a pixel count must be a whole number, in Wide VGA displays it is generally rounded up to 854 to ensure inclusion of the entire image. The frames are displayed progressively as opposed to interlaced. 480p was used for many early plasma televisions.CNET Glossary - 480p Standard definition has always been a 4:3 aspect ratio with a pixel resolution of at 60 Hz for NTSC regions, and 720 or for PAL regions (1024 wide for widescreen displays). However, standard definition defines a 15.7k Hz horizontal scanrate, which means that interlacing has to be used for those resol ...

1080p
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projector ...

Aspect Ratio (image)
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as ''16:9'', sixteen-to-nine. For the ''x'':''y'' aspect ratio, the image is ''x'' units wide and ''y'' units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. Some common examples The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1.The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' ''American Cinematographer Manual'' (Many widescreen films before the 1970 SMPTE revision used 2.35:1). Two common videographic aspect ratios are 4:3 (1.:1), the universal video format of the 20th century, and 16:9 (1.:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspect ra ...

Display Resolution
The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays. It is usually quoted as ', with the units in pixels: for example, ' means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight". One use of the term ''display resolution'' applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels creating ...

Digital Subchannel
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main digi ...

Multiplex (TV)
A multiplex or mux (called virtual sub-channel in the United States and Canada, and bouquet in France) is a grouping of program services as interleaved data packets for broadcast over a network or modulated multiplexed medium. The program services are split out at the receiving end. In the United Kingdom, a terrestrial ''multiplex'' (usually abbreviated ''mux'') has a fixed bandwidth of 8 MHz CODFM of interleaved H.222 packets containing a number of ''channels''. In the United States, a similar arrangement using 6 MHz 8VSB is often described as a ''channel'' with ''virtual sub-channels''. Pay television multiplexes In regards to television, the term multiplex is often used to refer to a single broadcaster offering multiple channels of programming as a single bundle to its subscribers. The term is most synonymous with premium television services, such as those devoted to films (where the term evokes the symbolism of multiplex cinemas) or sports; for instance, film services may ...

Create (TV Network)
Create is an American digital broadcast public television network broadcast on digital subchannels of PBS member stations. The network broadcasts how-to, DIY and other lifestyle-oriented instructional programming 24 hours a day. History Create was launched on WGBH-TV DTV/Comcast Cable and WLIW DTV/Cablevision digital services, WNET's sister station, in 2004. Create was launched nationally on January 9, 2006. In 2009, APT started looking for a national network underwriter, while seven stations had found local underwriters that covered their network fees. Ten stations at this time were inserting local programming. With rating data becoming available with more experience handling multicast channels and greater licensing fees, some public TV stations were changing their channel lineup. Some were dropping a network off a channel and programming it independently. A well-known station, WETA-TV, dropped Create on its .2 channel for an independent how-to channel in January 2012.
