Editing Videotex (section)

===Japan===

Research in Japan was shaped by the demands of the large number of [[Kanji]] characters used in Japanese script.  With 1970s technology, the ability to generate so many characters on demand in the end-user's terminal was seen as prohibitive.  Instead, development focussed on methods to send pages to user terminals pre-rendered, using coding strategies similar to [[facsimile machine]]s.  This led to a videotex system called [[Captain (videotex)|Captain]]  ("Character and Pattern Telephone Access Information Network"), created by [[Nippon Telegraph and Telephone|NTT]] in 1978, which went into full trials from 1979 to 1981.  The system also lent itself naturally to photographic images, albeit at only moderate resolution. However, the pages typically took two or three times longer to load, compared to the European systems. [[NHK]] developed an experimental teletext system along similar lines, called CIBS ("Character Information Broadcasting Station"). Based on a 388×200 pixel resolution, it was first announced in 1976, and began trials in late 1978.  (NHK's ultimate production teletext system launched in 1983).
