乍一看,起初还以为是一张声卡,但后来看到卡上的连接埠输出设计,才知道这是一张TV卡。一直以来,TV卡都有一个“银盒子”,这是TV调谐器的心脏.以“银盒子”覆盖着TV调谐器的原因,为的不是保持机密,而是防止干扰内里滤波的调谐线路,全因普通电脑用的TV调谐器,是很易受到千扰的;因此制作TV卡。调谐器部分就要使用金属壳包围。虽然如此,TV卡与电脑主机内的其它装置由于太过密集,用以上方式,仍不能完全避过高频千扰,这也是一般TV Box较TV卡有较佳接收力的原因。不过,Fly TV Platinum用上新的TV调谐器后,不仅无需再用“银盒子”,还可得到更佳接收表现。
At first glance, at first thought it was a sound card, but then saw the card on the port output design, we know it is a TV card. TV cards all along have a “silver box,” the heart of the TV tuner, which covers the TV tuner in a “silver box,” not to keep secrets but to prevent tuning lines that interfere with internal filtering, All TV tuner used by ordinary computer is very susceptible to interference; TV card production. The tuner section is surrounded by a metal shell. However, the TV card and other devices in the host computer are too dense. In the above manner, the high-frequency interference can not be completely avoided. This is also why the general TV box has a better receiving power than the TV card. However, Fly TV Platinum with a new TV tuner, not only do not need to use the “silver box”, but also get a better reception performance.
