电视机energy star测试中有个Power Overhang State，标准上是这么描述的： Power Overhang State: A limited-duration power state within On Mode that is intended to facilitate a product’s rapid return to full On Mode functionality or provide time for the product to perform functions required for safe shutdown (e.g. operation of cooling fans) after being switched into a low power state by the user. 我们开始的时候以为是没有信号的状态，后来有人说overhang应该是电视机的一种功能，不知道大家都是怎样理解的呢？ 谢谢拉：）
