The first commercial television systems were black-and-white ; The beginning of color television was in the 1950s.
A practical television system needs to take luminance, chrominance ( in a color system ), synchronization ( horizontal and vertical ), and audio signals, and broadcast them over a radio transmission.
The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.
The first was the American NTSC ( National Television Systems Committee ) color television system.
A color television system is identical except that an additional signal known as chrominance controls the color of the spot.
The same basic format ( with minor differences mainly related to timing and the encoding of color ) is used for PAL, NTSC and SECAM television systems.
Currently, Federko is a television color commentator for Fox Sports Midwest during Blues broadcasts.
Veteran sportscaster Gary Thorne is the current lead television announcer, with Jim Hunter as his backup along with Hall of Fame member and former Orioles pitcher Jim Palmer and former Oriole infielder Mike Bordick as color analysts.
* The NTSC color broadcast system was engineered by RCA to be backward compatible with black-and-white NTSC television sets.
The idea of transmitting a color television signal with distinct luma and chrominance components originated with Georges Valensi, who patented the idea in 1938.
( t ) he use of two channels, one transmitting the predominating color ( signal T ), and the other the mean brilliance ( signal t ) output from a single television transmitter to be received not only by color television receivers provided with the necessary more expensive equipment, but also by the ordinary type of television receiver which is more numerous and less expensive and which reproduces the pictures in black and white only.
Previous schemes for color television systems, which were incompatible with existing monochrome receivers, transmitted RGB signals in various ways.
If the color burst signal were visible on a television screen, it would appear as a vertical strip of a very dark olive color.
Use was prevalent in televisions because transistors were slow to achieve the high power and frequency capabilities needed particularly in color television sets.
The first portable color television, the General Electric Porta-Color, was designed using 13 tubes, 10 of which were Compactrons.
Eisenhower was the first president to appear on color television.

color and video
* A replacement card for the original TRS-80 compatible video card, software compatible to the original one, but with added color and very high resolution capabilities.
The video card also supported 16 foreground and 16 background colors per character, by providing one byte per character position ( 2K ) of " color ram ".
One nibble of such a byte then controlled the foreground color, and the other nibble controlled the background color, a system very similar to the Sinclair ZX Spectrum, in fact in the 256x192 mode the display mode was virtually identical to the video of the Sinclair ZX Spectrum.
This video card would also support fast scrolling of high resolution color screens for games, because it had the indirection of the character pointers, so it was possible to quickly scroll the high resolution display, ( or use other effects ) by simply manipulating the 1920 / 1024 bytes of text video instead of the 24. 576 bytes of high resolution video memory.
From left to right: end of a video scan line, front porch, horizontal sync pulse, back porch with color burst, and beginning of next line
CRTs are still popular in the printing and broadcasting industries as well as in the professional video, photography, and graphics fields due to their greater color fidelity, contrast, and better viewing from off-axis ( wider viewing angle ).
For example, a digital video ( using a DV codec ) of a sports event needs to encode motion well but not necessarily exact colors, while a video of an art exhibit needs to encode color and surface texture well.
Chrominance ( chroma or C for short ) is the signal used in video systems to convey the color information of the picture, separately from the accompanying luma signal ( or Y for short ).
In composite video signals, the U and V signals modulate a color subcarrier signal, and the result is referred to as the chrominance signal ; the phase and amplitude of this modulated chrominance signal correspond approximately to the hue and saturation of the color.
Typically, the chrominance bandwidth is reduced in analog composite video by reducing the bandwidth of a modulated color subcarrier, and in digital systems by chroma subsampling.
In the PAL system, the color subcarrier is 4. 43 MHz above the video carrier, while in the NTSC system it is 3. 58 MHz above the video carrier.
The presence of chrominance in a video signal is indicated by a color burst signal transmitted on the back porch, just after horizontal synchronization and before each line of video starts.
Chrominance is represented by the U-V color plane in PAL and SECAM video signals, and by the I-Q color plane in NTSC.
This is called the color depth ( CD ) of the video.
An example video can have a duration ( T ) of 1 hour ( 3600sec ), a frame size of 640x480 ( WxH ) at a color depth of 24bits and a frame rate of 25fps.
In fact the same formula is valid for uncompressed video because in that case one can assume that the " compression " factor is 1 and that the average bits per pixel equal the color depth.
His work, as important as it was in its own right, was a part of a continuum of progress in communications and electronics that since his time has brought forward color television, the personal computer, the Internet, cable and satellite radio and TV, personal mobile phones, audio, video and computing, digital stereo radio on both the medium wave and VHF-FM bands, and digital high definition television on VHF, UHF, cable and satellite.

color and cameras
Before 1941, commercially successful color processes used special cameras loaded with black-and-white separation stocks rather than color negative.
Kinemacolor ( 1908 – 1914 ), Technicolor processes 1 through 4 ( 1917 – 1954 ), and Cinecolor used one, two or three strips of monochrome film stock sensitized to certain primary colors or exposed behind color filters in special cameras.
Technicolor introduced a color reversal stock, called Monopack, for location shooting in 1941 ; it was ultimately a 35 mm version of Kodachrome that could be used in standard motion picture cameras.
Although it is a deep and pure red color, spots of laser light are so intense that cameras are typically overexposed and distort their color.
A Casio 1. 8 in color TFT LCD, which equips the Sony Cyber-shot DSC-P93A digital camera | digital compact cameras
Some full color digital images are processed using a variety of techniques to create black and whites, and some manufacturers produce digital cameras that exclusively shoot monochrome.
* The vast majority of color digital cameras use a Bayer filter, resulting in a regular grid of pixels where the color of each pixel depends on its position on the grid.
In most digital cameras, the sensor array is covered with a patterned color filter mosaic having red, green, and blue regions in the Bayer filter arrangement, so that each sensor element can record the intensity of a single primary color of light.
RCA cameras and studio gear, particularly of the TK-40 / 41 series, became standard equipment at many American television network affiliates, as RCA CT-100 (" RCA Merrill " to dealers ) television sets introduced color television to the public.
Typical RGB input devices are color TV and video cameras, image scanners, and digital cameras.
Paramount took this concept a step further, using old Stein cameras that were originally meant for an aborted early 1930s color process.
Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green, due to the bayer pattern allocating more pixels to the green channel, mimicking the human eye's increased sensitivity to green light.
) In the digital world, however, green has become the favored color because digital cameras retain more detail in the green channel, and it requires less light than blue.
Infrared thermography color thermal imaging cameras ( used in formal energy audits ) can quickly document the negative thermal impact of roof-angled glass or a skylight on a cold winter night or hot summer day.
The sRGB color space standard used with most cameras, PCs, and printers does not use a simple power-law nonlinearity as above, but has a decoding gamma value near 2. 2 over much of its range, as shown in the plot to the right.
The advent of high-quality color videotape recorders and portable video cameras coincided with the DIY ethos of the New Wave era, enabling many pop acts to produce promotional videos quickly and cheaply, in comparison to the relatively high costs of using film.
Video from black-and-white or color cameras is fed into processors that analyze the changing characteristics of the video image as vehicles pass.
The TV camera consisted of a vidicon tube, 25 and 100 mm focal length lenses, shutters, polarizing filters ( as opposed to color filters used on the previous Surveyor cameras ), and iris mounted nearly vertically and surmounted by a mirror that could be adjusted by stepping motors to move in both azimuth and elevation.
