　　To make the technology as simple as possible, Sony, HP, and other vendors are finally creating software that can be used across all their devices—be it PCs, TVs, or set—top boxes.

　　為了讓科技盡可能的簡單，索尼、惠普和其他銷售者最終開發(fā)了可以在所有裝置上使用的軟件——不論是個人電腦、電視機或是數(shù)字解碼器——這種軟件就是機頂盒。

　　句首的不定式短語To make the technology as simple as possible作全句的目的狀語;

　　主句為Sony, HP, and other vendors are finally creating software…;

　　定語從句：關(guān)系代詞that引導的定語從句that can be used across all their devices修飾先行詞software，that在從句中作主語，并且使用了被動語態(tài);

　　第一個破折號后面是對across all their devices的具體說明，注意這里采用了whether…or…引導的讓步狀語從句省略whether的特殊形式be it PCs, TVs, or set;

　　第二個破折號后top boxes是對software的最終闡釋，我們?nèi)サ糁虚g讓步狀語作的分隔成分，可以連接全句為Sony, HP, and other vendors are finally creating software that can be used across all their devices—top boxes。
