1. Set the result C to the empty set.<br />
2. For each pair of capability descriptors (d1, d2), where d1 is from C1 and d2 is from C2,<br />
derive the permutations of alternative sets, s1 and s2. For each such permutation, where s1 is<br />
from d1 and s2 is from d2, intersect s1 and s2 (written as s=s1 ^ s2) and add s to C.<br />
3. Remove duplicate entries from C.<br />
6.2.4 S<strong>IP</strong>/DMIF Address Conversion Model<br />
6.2.4.1 MPEG-4 DMIF Address Definition<br />
DMIF address is an URL that allows the DMIF layer at the originating DMIF to parse the<br />
network address in order to establish a session with the designated target DMIF and subsequently<br />
locate a service entity to enable it. Optionally the DMIF URL can be used to locate the source of an<br />
Elementary Stream in MPEG-4. The DMIF URL follows the generic syntax for new URL schemes<br />
defined in RFC1738 [182].<br />
The DMIF URL on <strong>IP</strong> network consists of the following:<br />
xdmif://:@:/ or<br />
<br />
6.2.4.2 S<strong>IP</strong> Address Format<br />
A S<strong>IP</strong> address can be either a S<strong>IP</strong> URL or any URI. The BNF of a S<strong>IP</strong> address is given below<br />
for reference:<br />
S<strong>IP</strong>-Address = (name-addr | addr-spec)<br />
name-addr = [display-name] “”<br />
addr-spec<br />
= S<strong>IP</strong>-URL<br />
S<strong>IP</strong>-URL = ”sip:” [ userinfo ”@” ] hostport url parameters [headers]<br />
userinfo = user [ ”:” password ]<br />
hostport = host [ ”:” port ]<br />
host<br />
= hostname | <strong>IP</strong>v4address<br />
url-parameters<br />
= *(”;” url-parameter)<br />
url-parameter = user-param | ...<br />
6.2.4.3 Converting S<strong>IP</strong> Address to DMIF URL<br />
S<strong>IP</strong> address can be converted to DMIF URL facially. S<strong>IP</strong>-URL is copied verbatim to DMIF<br />
URL without any additional or supplement information.<br />
