net.sourceforge.jaad.mp4.boxes.impl.ProgressiveDownloadInformationBox

All Implemented Interfaces:

Box

public class ProgressiveDownloadInformationBox
extends FullBox

The Progressive download information box aids the progressive download of an ISO file. The box contains pairs of numbers (to the end of the box) specifying combinations of effective file download bitrate in units of bytes/sec and a suggested initial playback delay in units of milliseconds. The download rate can be estimated from the download rate and obtain an upper estimate for a suitable initial delay by linear interpolation between pairs, or by extrapolation from the first or last entry.
