The primary difference between DigiCipher 2 and DVB lies in how each standard handles SI <a href="/wiki/Metadata" title="Metadata">metadata</a>, or System Information, where DVB reserves packet identifiers from 16 to 31 for metadata, DigiCipher reserves only packet identifier 8187 for its <a href="/wiki/Program_and_System_Information_Protocol" title="Program and System Information Protocol">master guide table</a> which acts as a <i>look-up table</i> for all other metadata tables. DigiCipher 2 also extends the MPEG <i>program number</i> that is assigned for each service in a transport stream with the concept of a <a href="/wiki/Virtual_channel" title="Virtual channel">virtual channel</a> number, whereas the DVB system never defined this type of remapping preferring to use a registry of <i>network</i> identifiers to further differentiate <i>program numbers</i> from those used in other transport streams. There are also private non-standard additions to DVB that add virtual channel remapping using <i>logical channel numbers</i>. Also unlike DVB, all text used in descriptors can be compressed using standard <a href="/wiki/Huffman_coding" title="Huffman coding">Huffman coding</a> which saves on broadcast bandwidth and loading times. DigiCipher II uses <a href="/wiki/Dolby_Digital" title="Dolby Digital">Dolby Digital AC-3</a> audio for all channels, although MPEG-1 Level 2 audio is not supported.<sup id="cite_ref-auto_2-1"
