High-definition video

High-definition video is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition, generally any video image with considerably more than 480 horizontal lines (North America) or 576 horizontal lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing.

History

The first electronic scanning format, 405 lines, was the first "high definition" television system, since the mechanical systems it replaced had far fewer. From 1939, Europe and the US tried 605 and 441 lines until, in 1941, the FCC mandated 525 for the US. In wartime France, René Barthélemy tested higher resolutions, up to 1,042. In late 1949, official French transmissions finally began with 819. In 1984, however, this standard was abandoned for 625-line color on the TF1 network.

Sound recording and reproduction

Sound recording and reproduction is an electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a small microphone diaphragm that can detect changes in atmospheric pressure (acoustic sound waves) and record them as a graphic representation of the sound waves on a medium such as a phonograph (in which a stylus senses grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a bigger loudspeaker diaphragm causing changes to atmospheric pressure to form acoustic sound waves. Electronically generated sound waves may also be recorded directly from devices such as an electric guitar pickup or a synthesizer, without the use of acoustics in the recording process other than the need for musicians to hear how well they are playing during recording sessions.

Ultra-high-definition television

Ultra-high-definition television (also known as 2160p, UHD-1, Super Hi-Vision, Ultra HD television, UltraHD, UHDTV, or UHD) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU).

The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840×2160 pixels.

Alternative terms

Ultra-high-definition television is also known as Ultra HD, UHD, and UHDTV. In Japan, 8K UHDTV will be known as Super Hi-Vision since Hi-Vision was the term used in Japan for HDTV. In the consumer electronics market companies had previously only used the term 4K at the 2012 CES but that had changed to Ultra HD during the 2013 CES. The Ultra HD term is an umbrella term that was selected by the Consumer Electronics Association after extensive consumer research.

Koch Entertainment

Koch Entertainment (now Entertainment One) was a North American film, television, & music distribution company. It was purchased by E1 Entertainment in 2005 and as of 2009 now operates under the name Entertainment One.

History

The company began in 1975 as part of Koch International originally of Tirol, later of Munich. Founded by Tirolean banker Franz Koch, Koch was an independent Austrian record label, recording studio, and music distribution company that specialized in German Folk Music and later popular classical music recordings. For over 20 years, the international arm of the company operated under the name Koch Entertainment, a music, film, and television distribution company that was started in 1987 by Franz's son Michael in New York. In 1988, the parent Austrian company Koch acquired Schwann Records from Schwann Verlag.

By 1991, Koch had become one of the first national independent distributors of domestic labels in the U.S. by offering an alternative to the traditional system of regional independent distribution or national major label distribution. In 1992, Koch was ranked #315 on Inc. Magazine’s list of America’s 500 fastest-growing private companies, and has since grown into an entertainment conglomerate. It acquired the specialist German label Schwann, Koch expanded into the Canadian market in 1995 by forming the Toronto-based Koch Entertainment Canada. In 1996, Koch International took over Discover, a budget label which had been set up by conductor Alexander Rahbari to challenge the dominance in the budget classical sector of Naxos. The new Koch Discover International was to be jointly controlled by Franz Koch and Rahbari. The Austrian parent Koch divested Schwann to Deutsche Grammophone's parent Universal Music GMbH in 2002.
