Satellite trucks usually travel with a production truck, which contains video cameras, sound equipment and a crew. A satellite truck has a large satellite dish antenna which is pointed at a communication satellite, which then relays the signal back down to the studio. Satellite communication allows transmission from any location that the ...
In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
Mechanical TV usually only produced small images. It was the main type of TV until the 1930s. Vacuum tube television, first demonstrated in September 1927 in San Francisco by Philo Farnsworth , and then publicly by Farnsworth at the Franklin Institute in Philadelphia in 1934, was rapidly overtaking mechanical television.
Cable transport is a broad class of transport modes that have cables. They transport passengers and goods, often in vehicles called cable cars . The cable may be driven or passive, and items may be moved by pulling, sliding, sailing, or by drives within the object being moved on cableways .
Since analog transmission of video is scan line-based, the same number of horizontal lines is always transmitted. However, several factors impede the ability to display fine detail within a line: The camera or other source of material. The storage and processing of the picture. The transmission of the TV signal e.g. broadcast by radio or by cable.
With the advent of metal–oxide–semiconductor field-effect transistors (MOSFETs), integrated circuit (IC) chips, microprocessors, and microelectronic devices, many more individual picture elements ("pixels") could be incorporated into one display device, allowing graphic displays and video.
Detail view of an LED display with a matrix of red, green and blue diodes The 1,500-foot (460 m) long LED display on the Fremont Street Experience in Downtown Las Vegas, Nevada, is currently the largest in the world. A LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) as pixels for a video display.
Many motion blur factors have existed for a long time in film and video (e.g. slow camera shutter speed). The emergence of digital video, and HDTV display technologies, introduced many additional factors that now contribute to motion blur. The following factors are generally the primary or secondary causes of perceived motion blur in video.
