To achieve this, the luminance signal must be low-pass filtered, dulling the image. In composite video, the signals co-exist on different frequencies. The luminance signal carries horizontal and vertical sync pulses in the same way as a composite video signal. This signal contains two color-difference components. Y is the luma signal, which carries the luminanceВ вЂ“ or black-and-whiteВ вЂ“ of the picture, including synchronization pulses.Д¬ is the chroma signal, which carries the chrominanceВ вЂ“ or coloring-inВ вЂ“ of the picture. The S-video cable carries video using two synchronized signal and ground pairs, termed Y and C. It eliminates the final mixing of C with Y and subsequent separation at playback time. To retain that quality in the final image, it is desirable to eliminate as many of the encoding/decoding steps as possible. To play back composite video, the Y and C signals must be separated, and this is difficult to do without adding artifacts.Д®ach of these steps is subject to deliberate or unavoidable loss of quality. The resulting Y and C signals are mixed together to produce composite video. This signal is then bandwidth-limited to comply with requirements for broadcasting. The phase and amplitude of the signal represent the two original signals. The first step is to combine the Pb and Pr to form the C signal, for chrominance. To recover the original RGB information for display, the signals are mixed with the Y to produce the original blue and red, and then the sum of those is mixed with the Y to recover the green.ДЄ signal with three components is no easier to broadcast than the original three-signal RGB, so additional processing is required. Once the Y signal is produced, it is subtracted from the blue signal to produce Pb and from the red signal to produce Pr. This signal closely matches a traditional black and white television signal and the Y/C method of encoding was key to offering backward compatibility. The first of these signals is called Y, which is created from all three original signals based on a formula that produces an overall brightness of the image, or luma. The image is originally captured in RGB form and then processed into three signals known as YPbPr. Standard analog television signals go through several processing steps on their way to being broadcast, each of which discards information and lowers the quality of the resulting images.

The first model was manufactured from 1887 to 1902. Minor design changes were made to these revolvers over the years, resulting in several different design models, as termed by collectors. They were known as 'The New Departure' to reflect the company's new approach to designing revolvers. These top-break revolvers were designed for fast reloading and concealed carry as the hammer was internal and would not snag on drawing the revolver from a pocket. They were most often produced with a 2-inch, 3-inch, or 3.5-inch barrels but some 6' barrelled versions are known to exist. 38 Safety Hammerless models were produced from 1887 (1888 for the 32) to just before World War II.
