ASF, abbreviate for Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format), is a Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. It is a part of the Windows Media framework and therefore playing ASF videos under a Windows operating system with built-in WMP is quite easy.
However, if you want to watch ASF files on Mac, then you are going to have to download VLC media player to view it - You could not open the video in QuickTime by default. What if this for iOS device? As we know, Apple iOS devices only accept video ended with .mp4, .mov and .m4v extension. Obviously, there isn't straightforward way to go, you will need to convert your ASF videos into the broad compatibility of MP4 (or mov/m4v) that will play on your Apple TV, iPhone, iPad etc.
