问N H K当初设计高清电视的初衷是什么?回答大大出乎意料。70年代日本楼价飞涨,家居细小,逼迫大家在2米左右观看彩电,闪烁的扫描线令人头晕。N H K经过试验,发现增加一倍的扫描频率,并用有效像素填补其上的空白,就能让人容忍了。今天,虽然我们知道高清的带宽是标清的5倍,画面细腻逼真、晶莹剔透,高分辨平板也已梦想成真。但BSD的观看距离,始终没有跳出原来的框框。即使是47英寸的FullH D液晶,也只能在2米以内观看。中国人比日本人气派,客厅宽度往往超过6米。平板电视挂墙安装,使观看距离更恶劣。我将沙发向前挪了又挪,后方半个客厅空置了。为了拉长观看距离,有人提议用大屏幕投影,但除非是专业的三枪,否则一定扫兴而归。好消息是松下即将量产100英寸级别的PD P,才能满足BSD玩家的终极要求。
Q. What was the original intention of N H K to design HDTV? The answer was greatly unexpected. 70s in Japan soaring property prices, home small, forcing everyone to watch TV at about 2 meters, flickering scan line is dizzy. N H K has been tested to find it doubly tolerant to find that doubling the scan frequency and filling in blanks with valid pixels. Today, although we know that the bandwidth of HD is 5 times that of standard definition, the picture is vivid, crystal clear, and the high resolution tablet has also come true. But BSD’s viewing distance, never jump out of the original box. Even the 47-inch FullH D LCD can only be viewed within 2 meters. Chinese people are more Japanese than the Japanese, the living room width is often more than 6 meters. Wall-mounted flat-panel TVs to make viewing distance even worse. I moved the couch forward and backward, leaving half a living room behind. In order to extend the viewing distance, it was proposed to use large-screen projection, but unless it is a professional three shots, otherwise it will disappoint. The good news is that Panasonic is about to mass-produce a 100-inch level of PD P to meet the ultimate BSD player’s needs.
