那么从前需要安装无数个解码编码器才能播放电影和MP3文件的情况是否有所好转呢？

结果差别是巨大的：例如在iPhone上，h . 264格式的视频能播放10小时以上，但如果视频以软解码形式播放，不到五个小时电池就将完全耗尽。
The difference is striking: on an iPhone, for example, H.264 videos play for up to 10 hours, while videos decoded in software play for less than 5 hours before the battery is fully drained.
一旦碟片认为播放机是合法的而且没被破解，它就会允许解码和播放碟上的影片。
Once the disc decides the player is legitimate and hasn't been compromised, it allows the movie it contains to be decrypted for playback.
