One kind of time delay is the use of tiny loudspeaker that plays the video signal into a tiny glass chamber where a tiny microphone picks it up at the other end. Another is similar except that a thin glass fibre transmits the signal from the speaker to the microphone like a toy tin can and string telephone. Still others (CCDs, or charged coupled devices) use silicon chips with a chain of \u2018charged cells\u2019 so as to make the signal travel slower as is passes through. The circuits are arranged so that the video signal goes through both the apparatus described above and through a straight wire.  <\/p><div class=\"rqjqn6a0dc85241b3e\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 television-and-video -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"6549443290\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.rqjqn6a0dc85241b3e {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.rqjqn6a0dc85241b3e {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.rqjqn6a0dc85241b3e {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.rqjqn6a0dc85241b3e {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.rqjqn6a0dc85241b3e {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"kopiq6a0dc85241ac6\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.kopiq6a0dc85241ac6 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.kopiq6a0dc85241ac6 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.kopiq6a0dc85241ac6 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.kopiq6a0dc85241ac6 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.kopiq6a0dc85241ac6 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\">At the other end where the signals are mixed, when the current line is coming down the wire, the previous line is coming out of the delay appa- ratus.
