<P> The information in the upper right - hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals . The top drawing shows the typical signal that occurs at the start of a picture . The picture is made from this signal, which traces the picture as a series of vertical lines, similar to analog television (in which the picture is a series of horizontal lines). Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the "picture lines," about 8 milliseconds, is noted . The drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition . Immediately below this is a drawing of an entire picture raster, showing that there are 512 (2) vertical lines in a complete picture . Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly . A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction . Color images were represented by three images in sequence, one each for red, green, and blue components of the image . A color image of the spectrum of the sun was included for calibration purposes . </P> <P> The drawing in the lower left - hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11 . It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given . The drawing containing two circles in the lower right - hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that the time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for the time given on the cover and in the decoded pictures . </P> <P> Much like the Pioneer Plaque, controversy surrounded the complexity of the record and its accompanying stylus . </P> <P> Blank records were provided by the Pyral S.A. of Creteil, France . CBS Records contracted the JVC Cutting Center in Boulder, Colorado to cut the lacquer masters which were then sent to the James G. Lee Record Processing center in Gardena, California to cut and gold plate eight Voyager records . After the records were plated they were mounted in aluminum containers and delivered to JPL . </P>
