When you set up an MBR stream your content is encoded at every bit rate you specify.&nbsp; When a player receives an MBR stream, only the stream that is the most appropriate for current network conditions plays.&nbsp; The Windows Media server and player handle the process of selecting the appropriate stream, which is invisible to the user.&nbsp; You can only use CBR encoding when creating an MBR stream.</p> <p class=level_1_indented>You can encode MBR streams for both audio and video content; however, it is not necessary to use MBR encoding for both audio and video in a single stream.&nbsp; For example, you can stream audio at one bit rate and have multiple bit rates for the video portion of the stream.&nbsp; Also keep in mind that encoding an MBR stream uses more processing power.&nbsp; Select a range of bit rates that you think will meet the playback needs of the audiences you are targeting.</p> <p class=level_1_indented><u><b>Selecting Bitrates</b></u></p> <p class=level_1_indented>For files that will be streamed over a network, you must consider carefully what bit rates you should use.&nbsp; Under most circumstances you can add the bit rates of all of the streams in a file together to get a general idea of the available bandwidth required to stream the file.&nbsp; However, a certain amount of overhead is also required for each stream.&nbsp; This overhead is summarized in the following table:</p> <p class=level_1_indented> <TABLE style="BACKGROUND-COLOR: #ffffff; BORDER-COLLAPSE: collapse" id=table1 class=stats border=1 cellSpacing=0 borderColor=#111111 width=421 height=124> <TBODY> <TR> <TD bgColor=#c0c0c0 height=32 width=189><b>Bit Rate Range (Kbps)</b></TD> <TD bgColor=#c0c0c0 height=32 width=224><b>Additional Bandwidth Required for overhead (Kbps)</b></TD></TR> <TR> <TD height=12 width=189>10 - 16</TD> <TD height=12 width=224>3</TD></TR> <TR> <TD height=12 width=189>17 - 30</TD> <TD height=12 width=224>4</TD></TR> <TR> <TD height=12 width=189>31 - 45</TD> <TD height=12 width=224>5</TD></TR> <TR> <TD height=12 width=189>46 - 70</TD> <TD height=12 width=224>6</TD></TR> <TR> <TD height=12 width=189>71 - 225</TD> <TD height=12 width=224>7</TD></TR> <TR> <TD height=12 width=189>&gt;

The average available bandwidth for any given connection falls well short of the bandwidth capacity of the connection, because of network traffic and many other factors.</p> <p class=level_1_indented><u><b>Preserve ID3 Tags (file description details)</b></u></p> <p class=level_1_indented>By default, Digital Media Converter Pro retains metadata (like song titles and names of the artists) from your source file.&nbsp;
