Mechanical television



TV History The mechanical part consists mostly of a mechanical Nipkow disk, which has several holes in a spiral path. The bedroom is the disk is a device sensitive to light, usually behind a light barrier. Player (display), a modulated light source, usually a neon tube, and the light sensor. Each hole in-the-fly generated to look for a line. AM radio or scan CCTV implementation model reproducer.Block system.Facsimile mechanical scanner still images from the early mechanical television uses the early 1800s. For example, Shelford Bidwell has shown how the system in 1881. For decades, the scanning system was the first pioneer in the broadcasting and the drawings. Download the images was a challenge. Selenium photocells at the beginning of a very low sensitivity. Scan resolution of the image is suitable for newspaper reproduction, it can take several minutes. With a two-tone silhouette images and immediate access to a modern image to the TV thanks to a copy of the head 1909.Baird "Bill Stooky" dolls similar to JL Baird in his early experiences with television. Paintings, probably comparable to quality.In 1920, Yasujiro Niwa Japanese scientists invented a simple device and cable broadcasts and radio, and then photo telegraphic. American inventor Charles Francis Jenkins has developed a mechanical television in 1920 and 1930. In 1923 Jenkins sent the first form of moving images and 13 June 1925 showed that the image of public television and transmits a live sync sound.Mechanical image colors (gray) by British inventor John Logie Baird 26th January 1926 is shown in his laboratory in London. Unlike later electronic systems for hundreds of lines of vertical resolution of the scanned image Baird, scan the hard drive integrated with a double spiral of lenses, had only 30 lines long enough to have a face. Why identify the man, only a limited number of holes and washers in a certain diameter has become impossible, resolution of the images on television, was a mechanic in the usually very low, 30-120 lines or less. Some systems are 200 parts of the network is in the air. Two of them are 180 rows of counters and the Company (CDC), which was founded in Paris in 1935, Peck and 180 lines in 1935, the station began Montreal.Instead VE9AK Nipkow disc, an engineer, other TV technologies have. Other agreements are often a rotating drum, then a row of holes or reflects them. another scanner scanning method is the place to fly ", instead of flying. "Cruise business has developed to the lack of sensitivity of the photodetector, which is at that time. Ray of Light, the light through the narrow openings Nipkow disk seems correct. The light is a problem of light TV, in the dark studio. Whipping and continue up and down, a point of light, or more than sixteen times per second. light is reflected not just one, but the bank photocells combined. the signals from these cells was a strong image. mechanically, like television, is that Bush flies this image transmission technology (fax). This assay, like the BBC 1800s.The point to 1935, was flying. German television methods instead of flying until 1938. This year, at the end of the flight-tech scanner inventor. German Manfred von Ardenne, the scanner, instead of flying cathode ray tube as a source of light. In 1950, Dumont sold Vita scan, a full test flight of the color. Today, scanner, graphics, navigation still using this method. Flying spot method has two disadvantages: The players are working in the dark, and flying machines tend outdoors in well-known TV daylight.A unstable by the scanner instead of a leak Ray Kell work in 1928, the General Electric scanner instead of the United States showed that the fly can be used outdoors. Scanning light source should be clear that other accidents illumination.Kell an engineer who was the camera that the images are 24 lines of the New York governor Al Smith, was Smith .

Internet TV is a revolution in the development of television



Last month, SARFT selected IPTV licenses in the last seven points in three, in order for the first time you launch an Internet-authorized television, is a leader in a new series of TV debates Internet.

TV manufacturers in accordance with the conflicts of the past practice of connections over the Internet TV is in the form of access to traditional TV, Internet, Internet users to access television, to install the contents of the traditional cable TV. CEO of Internet TV SARFT is also on this premise. At the end of a series of pipes with TV, radio and television (TV on your computer and the phone radio and television tubes in possession) of the document to prevent all out, only the transmission of reliable service with three points to the vacancies is their goal, continue to monitor closely the content. SARFT TV manufacturers and the discrepancy is not as it should, because if they are in China, the contents on computers that are not on another terminal to see even irrational to look like (except for copyright). Problems in crisis management policy is a pre-Internet content and content management standards for television programs as diverse as Phoenix TV, Internet and may appear to be legitimate, and the television or the ground. Content is managed, but the Internet and the various industry standards are not justified. At the same time, technological innovation TV on the Internet to improve the user experience is good, but "you do not see the contents of the TV:" The main selling point of the head.

Radio and television influences the affinity and harmony



From: Toru Denghong Cheng Yong In recent years, digital technology has made the development of new active media, media development has entered a new era of rapid development. In an increasingly competitive situation has changed radically, to promote radio and TV as academic development, social harmony in the mainstream media in the main game? I think TV should be added to increase the affinity of the starting point on the target, try to influence the affinity and harmony. 1, radio and television called influenceThe kinship and affinity, there are two or more substances to the point where the momentum. Radio and television are concerned, it is close to reality, life, the ability to bind the masses. "The first people to connect, solid progress" our party "to serve the people wholeheartedly" from the Yan'an period, the radio, the main transfer 17, the signal is a continuation of this tradition and affinity. Impact on the link refers to persons or property, the role in life. Radio and television are concerned, it is, the flag, which acts as the general situation, to maintain the ability to treat the infection. Our group of soldiers and civilians during the war he spent listening to the radio while sitting your profile today, the earthquake left the audience, is a manifestation of this effect, and confirmed. TV and radio affinity and interact with each other was never isolated, but closely linked. Affinity is life, is to ensure that radio and television in their lives. Influenza has a soul, is the well-being of the Radio and TV button to be determined. The improvement in the affinity of the social impact of radio and television are the blows stronger. To increase the impact of radio and television, family and social benefits. The improvement in the affinity of the condition, manipulation, the effect on the result, to improve the target. These two issues are closely linked. Second, the greatest affinity led influenceDigital for the improvement of technology for the benefit of television and radio and television reception is not just for radio, television, newspapers and other improvements in the traditional media, the media and innovation to improve productivity, but leads also to online media, mobile devices, the emergence of new media model for the development of media and the public and control. Changes in the media in this competition, to stabilize the region and to improve the social impact? I think the most important thing is to play a dominant feature of radio and television programs is to try to improve the affinity, the first dish. Mediate in the last few years all radio and television, "the closure of three," information about the content of interactive participation in live performance and therefore useful for research. News livelihood viewers seem normal and appropriate, has been seriously attempted. Especially for those who are faced with a difficult group, "authority" to seek to defend their interests, "Pass". If the other's attitude, "attention" to the public, whether the media in order to solve the problem, which can solve the problem to maintain. News, such as changes in the position that it is, the new values to people's expectations are public, is how to respond. Popular and widely used Author believes that the reason why people whose livelihoods most viewers news about the industry and welcomes the interest of researchers not only from the perspective of the changes in the definition of the problem, but the voice on the radio, on TV and the picture of the actual development of affinity. That the press, internet and other media, "cloning" the story of the life of the people, and less influence on the master node. Speaks a dialect as the language of the rule in the vernacular, it is easy to accept the masses is a seat that has a high affinity. Dialects as the language of ancient and modern phenomenon known to strongly promote and Putonghua in the electronic media in line with reality and the rational use of limited area, has a higher affinity for the expression.

The employment prospects and TV



They work in the media, radio and television time and again a magnet for many. Young people are all over the world, especially the rapid development attracted to the creative industry and can be controlled separately for a unique global connectivity. Television, although the demand still strong competition from rival network capabilities that work online or in the early morning hours of TV production base programs to long, fine, but the rapid deployment of applications that use the TV-production together. In addition, the roles and responsibilities of the majority of production will be coordinated. This is most clearly interpreted in productions in which news analysts, journalists and TV news is also known as the messages and transmit the information collected and used by journalists and correspondents from various sources of information. Similar to the press, radio and television want to hire people with the University of media or journalism, with experience in a step-business media and publishing industry to a school where they the basic operations of the media, such as information gathering, writing, to learn journalism, publishing, and the pressure of deadlines in the first attempt. TV jobs are candidates who are willing to give for the industry. TV journalists, reporters, correspondents, news directors, engineers, technicians, production assistants, actors, producers, manufacturers, promotion, control of the script, these are just some of the most common and most interesting television. During the contest, the top candidates is among the major TV stations in urban areas, better employment opportunities for small stations or TV channels.

In 2018 we expect a slight increase of 5.97 percent or 8000-134800. Most of these occupations are part of the production team, led w tym technician if the network operates 24 hours run.Working on TV, but it requires commitment, not only, but also the need for continued structural integrity, particularly with suppliers, dealers and turning the Web. In a society where the characters are credible and respected in the nature of their work, it can be assumed that their private activities in public spaces as well as to expand his personality on TV. It is no wonder that many young people in jobs where public television journalist, adventure, science and celebrities are often interested in the combination. If you suspect that you have the skills and dedication of a new adventure in war-torn Afghanistan or the public channel for the popular journalist whose integrity expand public information, so be prepared to road.Television also to work here, as It may seem simple, fascinating for many people, the question that to have a lot of attention to detail, are filled with the atmospheric pressure, a total team effort from all sides.
