Private Sessions 5. Private sessions will typically be conveyed by encrypting the session description to distribute it. The details of how encryption is performed are dependent on the mechanism used to convey SDP - see [4] for how this is done for session announcements. Obtaining Further Information about a Session 5. Categorisation 5. SDP supports a categorisation mechanism for sessions that is capable of being automated. Internationalization 5. However, to assist in compact representations, SDP also allows other character sets such as ISO to be used when desired.

Internationalization only applies to free-text fields session name and background information , and not to SDP as a whole. SDP Specification 6.

However, since the total bandwidth allocated to all SAP announcements is strictly limited, the encoding is deliberately compact. Also, since announcements may be transported via very unreliable means e. This also allows rapid discarding of encrypted announcements for which a receiver does not have the correct key. It also will be case-significant unless a specific field defines otherwise.

In general, session-level values are the default for all media unless overridden by an equivalent media-level value. Some lines in each description are required and some are optional but all must appear in exactly the order given here the fixed order greatly enhances error detection and allows for a simple parser. Some attributes the ones listed in this document have a defined meaning but others may be added on an application-, media- or session-specific basis.

The sequence CRLF 0x0d0a is used to end a record, although parsers should be tolerant and also accept records terminated with a single newline character.
