As a consequence, the ATSC digital television standard states that for i signals, SMPTE "C" colorimetry should be assumed unless colorimetric data is included in the transport stream. Color encoding[ edit ] For backward compatibility with black-and-white television, NTSC uses a luminance - chrominance encoding system invented in by Georges Valensi. The three color picture signals are divided into Luminance derived mathematically from the three separate color signals Red, Green and Blue which takes the place of the original monochrome signal and Chrominance which carries only the color information. This process is applied to each color source by its own Colorplexerthereby allowing a compatible color source to be managed as if it were an ordinary monochrome source.
It specifies a An RS video frame contains lines and is displayed 60 times per secondfor a total of 15, lines, or Of these lines, only the odd or even lines are displayed with each frame.
A total Rs 170 60 frames per second allows 30 frames per second, or a Hz update of each line. The video signal encodes light intensity as a function of position.
Position is represented by time and light intensity by voltage. This signal lso included horizontal and vertical synchronization information. RS was the original "black-and-white" television signal definition, per EIA. The original standar defined a 75 ohm system and a 1. Signal level speficiations form RS were: To minimize flicker apparent at 30 Hz, the video signal is "interlaced", so that for each frame, first odd and then even scan lines are displayed.
Each frame is composed of two fields, one consisting of The Hz field rate was chosen to avoid interference from ac current fields. Original RS is strictly a timing specification for monochrome video signals.
Monochrome RS Video Black and white monochrome cameras are the simplest. They have single output cable which carries an RS video signal.
RS signal contains both image and timing information. The image is sent one line at a time, encoded using analog variation. The timing information consists of horizontal synch signals at the end of every line, and vertical synch pulses at the end of each field.
There are also so-called horizontal and vertical blanking periods at the end of each line and field respectively, during which no image information is sent. The non-displayable lines in each field constistute the vertical blanking period. The RS standard specifies an image with lines, of which the first are displayable.
The image information is actually sent in what is known as "interlaced" mode: The odd lines 1, 3, 5, Each set of lines constitutes a "field". Fields are sent at a rate of 60 per second, which means that the entire image frame is refreshed 30 times a second.
The reason for the interlaced format was to reduce perceptual flicker in the image displayed on a TV. Horizontal resolution depends on the camera and other video system components.
Since it is an analog signal, the exact number is not critical; it just limits the detail that can be resolved. The horizontal resolution of an analog video image is limited by the signal quality, as determined by all hardware--the video camera, storage medium if usedintervening cables and circuitry, and display technology.
Black and white cameras and CRT display tubes can resolve detail approaching or exceeding video lines. Typical resolution specs are on the order of elements per line. This empirically defined quantity is the number of pairs of black and white parallel lines that could be counted across the display monitor at the limit of detection by a human observer.
The intensity information available in the video signal is limited by the dynamic range the range of light intensities that can be detected and the signal-to-noise ratio. The dynamic range is generally determined by the video camera.
The aspect width to height ratio for typical RS signal rectangle is 4: The vertical resolution of video is limited to pixels, as determined by the number of scan lines. Digitizing RS video A typical digital image produced by video digitization would have a resolution of horizontal X vertical pixel resolution and would have individual pixels with a 5: If you want square pixels, you have to digitize pixels for each of the lines.
A fairly standard policy is to digitize lines at pixels per line just leave out few scanlines and pixels from horizonal lines.
Square pixels can simplify image spatial analysis and editing operations.A perfect five stars are given for this Sennheiser RS Digital Wireless Headphone with Dynamic Bass and Surround Sound.
