It carries no encoding-specific parameters or timing information global to the presentation. <p> <h3> Comparing different formats </h3> Not all of the attributes in a <code>Format</code> object have to be specified. This enables selected attributes to be specified, making it possible to locate a supported <CODE>Format</CODE> that meets certain requirements without needing to find an exact match. <p> Two methods are provided for comparing <code>Formats</code>. The <code>equals</code> method returns <CODE>true</CODE> if two <CODE>Format</CODE> objects are exactly the same--they're the same type and all of their attributes are the same. The <code>matches</code> method relaxes the comparison, comparing only the attributes that are explicitly specified in the <CODE>Format</CODE> you are comparing.<P><DL><DT><B>Since: </B><DD>JMF
