Simple Profile

Simple Profile in this context is one of the video encoding layers available inMPEG-4 standard and is probably the most widely used.

Popular MPEG-4codecs such asDivX andXviD use Simple Profile and alsoAdvanced Simple Profile for video encoding.

Simple Profile is intended for use with low powered CPUs. As a result noB Frames are allowed. B frames, or Bidirectional-Predictive Encoded frames require two reference frames to be decoded, compared to the single referenceFrame required for P frames. Since ASP isn't designed with this hardware limitation in mind it supports B frames.

SimpleProfile is suited primarily for applications such as mobile phones and video conferencing where quality is less important than size. Video encoded to Simple Profile specifications is suitable forMuxing into a3GP Container for use on a 3G mobile phone network.
