Mark Krivosheev
Mark Iosifovich Krivosheev (July 30, 1922 – October 16, 2018) was a Soviet and Russian engineer and academic who made pioneering contributions to the development of television technology as a head of television study groups at CCIR and ITU-R. He was a key figure in establishing Rec. 601 and Rec. 709 technical standards for digital television broadcasting. Early life and career Krivosheev was born in 1922 in the Soviet Union. As a student at the Moscow Technical University of Communications and Informatics in 1945, he participated in broadcasting the first post-war television program in Europe. In 1946, he designed a scanning unit for displaying new standard 625-line television images for the first time. After graduating in 1946, Krivosheev joined the , where he led the broadcast studio since 1947. On September 3, 1948, he broadcast the world's first 625-line television programme. Standardization work at ITU Krivosheev began his decades-long involvement with the ITU's Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poltava
Poltava (, ; , ) is a city located on the Vorskla, Vorskla River in Central Ukraine, Central Ukraine. It serves as the administrative center of Poltava Oblast as well as Poltava Raion within the oblast. It also hosts the administration of Poltava urban hromada, one of the hromadas of Ukraine. Poltava has a population of History It is still unknown when Poltava was founded, although the town was not attested before 1174. However, municipal authorities chose to celebrate the city's 1100th anniversary in 1999. The settlement is indeed an old one, as archeologists unearthed an ancient Paleolithic dwelling, as well as Scythian remains, within the city limits. Middle Ages The present name of the city is traditionally connected to the settlement Ltava, which is mentioned in the ''Hypatian Chronicle'' in 1174.

Television Pioneers
Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting", which refers to an audio signal sent to radio receivers. Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was in ...

Technology And Engineering Emmy Awards
The Technology and Engineering Emmy Awards, or Technology and Engineering Emmys, are one of two sets of Emmy Awards that are presented for outstanding achievement in engineering development in the television industry. The Technology and Engineering Emmy Awards are presented by the National Academy of Television Arts and Sciences (NATAS), while the separate Primetime Engineering Emmy Awards are given by its sister organization the Academy of Television Arts & Sciences (ATAS). A Technology and Engineering Emmy can be presented to an individual, a company, or to a scientific or technical organization for developments and/or standardization involved in engineering technologies which either represent so extensive an improvement on existing methods or are so innovative in nature that they materially have affected the transmission, recording, or reception of television. The award is determined by a special panel composed of highly qualified, experienced engineers in the television indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDTV
High-definition television (HDTV) describes a television or video system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the standard video format used in most broadcasts: Terrestrial television, terrestrial broadcast television, cable television, satellite television. Formats HDTV may be transmitted in various formats: * 720p (): 921,600 pixels * 1080i () interlaced scan: 1,036,800 pixels (≈1.04Mpx). * 1080p () progressive scan: 2,073,600 pixels (≈2.07Mpx). ** Some countries also use a non-standard CTA resolution, such as : 777,600 pixels (≈0.78Mpx) per field or 1,555,200 pixels (≈1.56Mpx) per frame When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television). The increased resolution provides for a cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
625 Lines
625-line (or CCIR 625/50) is a late 1940s European analog standard-definition television resolution standard. It consists of a 625-line raster, with 576 lines carrying the visible image at 25 interlaced frames per second. It was eventually adopted by countries using 50 Hz utility frequency as regular TV broadcasts resumed after World War II. With the introduction of color television in the 1960s, it became associated with the PAL and SECAM analog color systems. A similar 525-line system was adopted by countries using 60 Hz utility frequency (like the US). Other systems, like 375-line, 405-line, 441-line, 455-line and 819-line existed, but became outdated or had limited adoption. The modern standard-definition digital video resolution 576i is equivalent and can be used to digitize an analogue 625-line TV signal, or to generate a 625-line compatible analog signal. History At the CCIR Stockholm Conference in July 1948 a first 625-line system with an 8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raster Scan
A raster scan, or raster scanning, is the rectangular pattern of image capture and reconstruction in television. By analogy, the term is used for raster graphics, the pattern of image storage and transmission used in most computer bitmap image systems. The word ''wiktionary:raster, raster'' comes from the Latin word ''wiktionary:rastrum, rastrum'' (a rake), which is derived from ''wiktionary:radere, radere'' (to scrape); see also rastrum, an instrument for drawing musical staff lines. The pattern left by the lines of a rake, when drawn straight, resembles the parallel lines of a raster: this line-by-line scanning is what creates a raster. It is a systematic process of covering the area progressively, one line at a time. Although often a great deal faster, it is similar in the most general sense to how one's gaze travels when one reads lines of text. In most modern graphics cards the data to be drawn is stored internally in an area of semiconductor memory called the framebuffer. ...

Digital Television
Digital television (DTV) is the transmission of television signals using Digital signal, digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format (4:3) of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same Bandwidth (signal processing), bandwidth as a single analog channel, and provides many new features that analog television cannot. A digital television transition, transition from analog to digital broadcasting began around 2000. Different digital television broadcasting st ...
