It also implements the <code>CaptureDevice</code> interface which further specializes the <code>DataSource</code> to handle data capturing. <p> A capture <code>DataSource</code> contains an array of <code>SourceStream<code>'s. These <code>SourceStreams</code> provide the interface for the captured data streams to be read. <p> The formats of the captured data can be manipulated by the <code>FormatControl</code> objects. There is one <code>FormatControl</code> per each capture stream. These controls can be obtained by the <code>getFormatControls</code> method. <p> A few methods from the <code>DataSource</code> are re-defined to support semantics of capture devices.<P><DL><DT><B>Since: </B><DD>JMF 2.0</DD><DT><B>See Also: </B><DD><A HREF="../../../javax/media/protocol/DataSource.html"><CODE>DataSource</CODE></A>, <A HREF="../../../javax/media/protocol/SourceStream.html"><CODE>SourceStream</CODE></A>, <A HREF="../../../javax/media/control/FormatControl.html"><CODE>FormatControl</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#connect()">connect</A></B>()</CODE><BR> Initialize the capture device.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#disconnect()">disconnect</A></B>()</CODE><BR> Close the capture device.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/media/CaptureDeviceInfo.html">CaptureDeviceInfo</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#getCaptureDeviceInfo()">getCaptureDeviceInfo</A></B>()</CODE><BR> Return the <code>CaptureDeviceInfo</code> object that describes this device.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/media/control/FormatControl.html">FormatControl</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#getFormatControls()">getFormatControls</A></B>()</CODE><BR> Returns an array of <code>FormatControl</code> objects.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#start()">start</A></B>()</CODE><BR> Start the data capture.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/CaptureDevice.html#stop()">stop</A></B>()</CODE><BR> Stop the data capture.</TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="getCaptureDeviceInfo()"><!-- --></A><H3>getCaptureDeviceInfo</H3><PRE>public <A HREF="../../../javax/media/CaptureDeviceInfo.html">CaptureDeviceInfo</A> <B>getCaptureDeviceInfo</B>()</PRE><DL><DD>Return the <code>CaptureDeviceInfo</code> object that describes this device.<DD><DL><DT><B>Returns:</B><DD>The <code>CaptureDeviceInfo</code> object that describes this device.</DL></DD></DL><HR><A NAME="getFormatControls()"><!-- --></A><H3>getFormatControls</H3><PRE>public <A HREF="../../../javax/media/control/FormatControl.html">FormatControl</A>[] <B>getFormatControls</B>()</PRE><DL><DD>Returns an array of <code>FormatControl</code> objects.
