As television broadcasting ritualeditThe Indian head test pattern became familiar to the large baby boom TV audiences in America from 1. United States national anthem. The Indian head was also used by the Canadian Broadcasting Corporation CBC in Canada in conjunction with its own monochrome test pattern, following the Canadian national anthem sign off in the evening, and during its final years in the late 1. SMPTE color bars. It was also used by Rhodesia Television RTV during British colonial times varying between Northern and Southern Rhodesia following the playing of God Save the Queen at closedown.

In Sweden the Indian head was used in test transmissions from the Royal Institute of Technology alongside the RMA Resolution Chart 1. Televerket and Chalmers University of Technology from 1. November 1. 95. 8 when it was replaced by the Sveriges Radio TV now Sveriges Television test card. It was also used in Brazil by Rede Tupi from its launch in 1. Brazilian television network to adopt colour television in 1. The Indian head pattern could variously be seen after sign off but while the station was still transmitting while transmitting prior to a typical 6 AM formal sign on or even during the daylight morning hours on newer low budget stations, which typically began their broadcast day with midday local programming around 1. AM. 3During the late 1. TV broadcast equipment required less adjusting. In later years the test pattern was transmitted for as little as a minute after studio sign off while the transmitter engineer logged required Federal Communications Commission USIndustry Canada transmitter readings, and then turned off the power. Towards the end of the Indian head TV era around the late 1. After an immediate transmitter power off, in lieu of the Indian head test pattern and its sine wave tone, a TV viewer heard a loud audio hiss like FM radio interstation noise and saw the video noise. Audio and video noise received on Indian head era TV sets respectively indicated the absence of analog aural and visual broadcast carriers. Consumer TVs typically did not have a no signal noise muting and blanking feature until the late analog TV period. When US broadcasters transitioned to color television, the SMPTE color bars superseded the black and white test pattern image. Generationedit. The RCA TK 1. C monoscope camera which generated the test pattern. The Indian head test pattern was not generated by pointing a camera at a card, as many older test patterns were. Rather, it was generated directly as a monochrome video signal by means of a monoscope tube, a specialized video camera tube with the pattern built into the tube. An RCA TK 1 test pattern generator monoscope is a 1. The monoscope tube is constructed similarly to a small cathode ray tube CRT, but instead of displaying an image, it scans a built in image, producing a video signal. The tube has a perfectly proportioned copy of the test pattern master art inside, permanently deposited as a carbon image on an aluminum target plate or slide. This perfect copy allowed all of the television studio and production control roomvideo monitors, and home television sets, to be identically adjusted for minimum distortions such as ovals instead of circles. When the monitor or TV set was correctly adjusted to show test pattern circles, the received pictures aspect ratio was exactly four units wide by three units high. Indian Head pattern with its elements labeled, describing the use of each element in aligning a black and white analog TV receiver. The graphic of the Indian and all of the patterns on the chart served specific purposes. With the chart many typical daily sometimes hourly adjustments on cameras, home, and studio monitors could be made. An experienced broadcast engineer could glance at the drawing of the Indian Chief and quickly know if everything was OK or if more careful adjustment was needed. Within the chart the tools necessary to adjust perspective, framing, linearity, frequency response, differential gain, contrast and white level brightness are all provided. The grid and circles were used for perspective, framing and linearity. The tapered lines marked with 2. The thin lines marked from 5. The gray bands emerging from the center off to the lower right and upper left were for differential gain, contrast, and white level. Only after the monitors were adjusted was an actual Indian head test pattern used. A cardboard mounted lithograph of the test pattern was typically attached to a rolling vertical easel in each TV studio, to be videographed by each studio camera during test time. Then the cameras were adjusted to appear identical on picture monitors, by alternately switching between and comparing the monoscope image and the test card image. Such adjustments were made on a regular basis because television system electronics then used hot vacuum tubes, the operating characteristics of which drifted throughout each broadcast day. Test patterns were also broadcast to the public daily to allow regular adjustments by home television set owners and TV shop repair technicians. In this regard, various features in the pattern were included to facilitate focus and contrast settings, and the measurement of resolution. The circular bullseyes in the centre and the four corners permitted uniform deflection yoke and oscillator amplitude adjustments for centering, pincushioning, and image size. The test pattern was usually accompanied by a 1,0. TV aural receiver was working. If the tone was pure sounding rather than a buzz or rattle, then transmitted speech and music would not be distorted. Hz is somewhat less annoying for technicians to hear for extended work periods. As a cultural iconeditAn actual Indian head test card, the pattern as printed on art grade white cardboard, was only of secondary importance to television system adjustment, but many of them were saved as souvenirs, works of found art, and inadvertent mandalas. By contrast, nearly all of the hard to open, steel shielded, vacuum glass monoscope tubes were junked with their hidden Indian head test pattern target plates still inside. The monoscope target plates were also small, a few inches in size, while the showy camera test cards were sized on the order of 1. The original art work for the Indian chief portrait was completed for RCAs research engineers by an artist named Brooks on August 2. The original portrait was done in pencil, charcoal, ink and zinc oxide. For about a year the Indian portrait was televised in the laboratory as the entire test pattern. It was later incorporated into the pattern of calibrated lines and shapes. The original portrait measures eight inches 2. Owl Cuddle Lovey Stitch.
