(2) Television reception a paratus, whether or not incorporating radio-broadcast receivers or sound or video record?ng or reproducing apparatus, for the display of signals (television sets). (3) Apparatus for the reception of television signals, without display capabilities (e-g., receivers of satellite television broadcasts). Monitors, pro'ectors and television sets utilize different technologies, such as CRT (cathode-ray tube), LCD (li uid c stal display), DMD (digital micromirror device), OLED (organic light emitting diode3 and p?sma, to display images. Monitors and projectors may be capable of receiving a variety of signals fiom different sources. However, if they incorporate a television tuner they are considered to be reception apparatus for television. (A) MONITORS OF A KIND SOLELY OR PRINCIPALLY USED IN AN AUTOMATIC DATA PROCESSING SYSTEM OF HEADING 84.71 This goup includes CRT and non-CRT (e.g., flat panel screen) monitors which provide a graphical presentation. of the data processed. These monitors are distinguishable fiom other types of monitors (see (B) below) and fiom television receivers. They include : (I) Those monitors which are capable of accepting a si a1 only from the central processing unit of an automatic data processin machine and, %refore, are not able to reproduce a colour image fi-om a corn osite vi eo signal whose waveform conforms to a broadcast D-MAC, etc.). They are fitted with connectors standard (NTSC, S E C ~ PAL, , characteristic of data processing systems (e.g., RS-232C interface, DIN or SUB-D connectors) and do not have an audio circuit. They are controlled by special adaptors (e.g., monochrome or graphics adaptors) which are integrated in the central processing unit of the automatic data processing machine. % (2) CRT monitors having a display pitch size starting at 0.41 mm for medium resolution, which gets smaller as the resolution increases. - (3) Those CRT monitors which, in order to accommodate the presentation of small yet welldefined images, utilize smaller dot (pixel) sizes and greater convergence standards than those applicable to the monitors described at (B) below and television receivers. (Convergence is the abili of the electron n(s) to excite a single spot on the face of the cathode-ray tube without isturbing any oft e adjoining spots.) 2' f? (4) CRT monitors whose video frequency (bandwidth), which is the measurement determining how man dots can be transmitted er second to form the ima e, is general1 15 MHz or greater. %hereas, in the case of t e monitors described at ) below, the andwidth is generally no greater than 6 MHz. The horizontal scanning equenc of these monitors varies according to the standards for various display modes, generally om 15 kHz to over 155 kHz. Many are ca able of multiple horizontal scannin frequencies. The horizontal scannin frequency o the monitors described at (B) be ow is fixed, usually 15.6 or z depending on the ap licable television standard. Moreover, the monitors of this 15.7 grou do not o erate in con ormity with national or international broadcast eequency stan ards for pu lic broadcasting or with frequency standards for closed-circuit television. P f, P d S g P r h r, The monitors of this group are characterised by low electromagnetic field emissions and they frequently incorporate tilt and swivel adjusting mechanisms, glare-free surfaces, flicker-free display, and other ergonomic design characterist~csto facilitate prolonged periods of viewing at close proximity to the monitor. (B) MONITORS OTHER THAN THOSE OF A KIND SOLELY OR PRINCIPALLY USED IN AN AUTOMATIC DATA PROCESSING SYSTEM OF HEADING 84.71 This oup includes monitors which are receivers connected directly to the video camera or recor er by means of co-axial cables, so that all the radio-fkequenc circuits are eliminated. They are used by television companies or for closed-circuit television &irports, railway stations, factories, hospitals, etc.). These apparatus consist essentially of devices which can enerate a point of light and display it on a screen synchronously with the source signa s. The Incorporate one or more ndeo amplifiers with which the intensity of the polnt can be variez They can, moreover, have separate inputs for red (R), green (G) and blue (B), or be coded in accordance with a particular standard (NTSC, SECAM, PAL, D-MAC, etc.). For reception of coded signals, the monitor must be equipped with a decoding device covering the separation o the R, G and B signals. The most common means of image reconstitution is e cathode-ray tu e, for direct vision, or a projector with up to three projection cathode-ray tubes; however, other monitors achieve the same objective by Qfferent means (e.g,, li uid crystal screens, diffraction of light rays on to a film of oil). These may be in the form of RT monitors or flat panel displays, e.g., LCD, LED, plasma. B f B a e (C) PROJECTORS Projectors enable the image normally reproduced on the screen of a television receiver or of a monitor to be rojected on an external surface. They may be based on CRT or flat panel (e.g., DMD, LCD, p asma) technology. P (D) RECEPTION APPARATUS FOR TELEVISION This group includes apparatus whether or not designed to incorporate a video display or screen, such as : (1) Receivers of television broadcasts terrestrial, cable or satellite which do not include a display device (CRT, LCD, etc.). sign s and convert them into a a modem for connection to the signal suitable for display. They Internet. These receivers are intended to be used with video recording or reproducin a paratus, monitors, projectors or televisions. However, devices which simply isolate higf -gequen?y television si als (sometimes called video tuners) are to be classified as parts in heading 85.2F (2) Television receivers for industrial use (e.g., for reading instruments at a distance, or for observation in dangerous localities). With this apparatus the transmission is often by line. (3) Television receivers of all kinds (LCD, plasma, CRT, etc.) used in the home (television sets), whether or not incorporating a radio-broadcast receiver, video cassette recorder, DVD player, DVD recorder, satellite receiver, etc. . PARTS Sub'ect to the general provisions regarding the classification of parts (see the General ~ x ~ ! a n a t Note o ~ to Section XVI), parts of the apparatus of this heading are classified in heading 8 29. The heading excludes, inter alia : (a) Video recording or reproducing apparatus (heading 85.21). h (b) Special purpose vehicles e.g., vans for broadcasting) permanently equipped with television receivers or other apparatus of this eading (generally heading 87.05). (c) Cinematographic projectors (heading 90.07) and image projectors of heading 90.08.
