Some even believe conditions are ripe for the United States to vault over the international competition in a field seen as vital to economic success in the 1990s and beyond..
“We’ve got a tremendous opportunity to leapfrog limited technology and really develop a television of the future．”said W.Russell. Neuman，a director of communication research at the media 1abotatory of the Massachusetts Institute of Technology.
Experts say the main reason for hope is that the Japanese and Europeans, with an early lead, may be locked into a technology that could become antiquated.

盡管美同在制造具有逼真圖象的電視機(jī)角逐中起步緩慢，但越來越多的科學(xué)家和工程師認(rèn)為美國(guó)有希望卷土重來。

馬薩諸塞理工學(xué)院媒介研究所通訊研究部主仟組曼說，“我們具有極好機(jī)會(huì)，跳越技術(shù)的限制，真正研制出未來的電視?！?br>專家們認(rèn)為，之所以有希望，其主要理由是“
日本人和歐洲人早期雖居領(lǐng)先地位．也許會(huì)被可能變得老化的技術(shù)拖住后腳，該技術(shù)是以模擬信號(hào)為基礎(chǔ)的，由攝像機(jī)模擬觀測(cè)到的景物與聲響并將其變?yōu)檫B續(xù)的電子波......
