RtcpSourceDescriptionChunk Properties |
The RtcpSourceDescriptionChunk type exposes the following members.
Name | Description | |
---|---|---|
![]() | Cname |
A non-unique identifier of the host of an Ssrc in the form of user@computer (e.g.
alice@biloxi.com)
|
![]() |
The email address, e.g., "John.Doe@example.com".
| |
![]() | Loc |
Depending on the application, different degrees of detail are appropriate for this item.
For conference applications, a string like "Murray Hill, New Jersey" may be sufficient.
|
![]() | Name |
The real name of the Ssrc, e.g., "John Doe, Bit Recycler".
|
![]() | Note |
The following semantics are suggested for this item, but these or other semantics MAY be
explicitly defined by a profile. The NOTE item is intended for transient messages
describing the current state of the source, e.g., "on the phone, can't talk". Or, during
a seminar, this item might be used to convey the title of the talk. It should be used
only to carry exceptional information and SHOULD NOT be included routinely by all
participants because this would slow down the rate at which reception reports and CNAME
are sent, thus impairing the performance of the protocol. In particular, it SHOULD NOT
be included as an item in a user's configuration file nor automatically generated as in a
quote-of-the-day.
Since the NOTE item may be important to display while it is active, the rate at which
other non-CNAME items such as NAME are transmitted might be reduced so that the NOTE item
can take that part of the RTCP bandwidth. When the transient message becomes inactive,
the NOTE item SHOULD continue to be transmitted a few times at the same repetition rate
but with a string of length zero to signal the receivers. However, receivers SHOULD also
consider the NOTE item inactive if it is not received for a small multiple of the
repetition rate, or perhaps 20-30 RTCP intervals.
|
![]() | Phone |
The phone number SHOULD be formatted with the plus sign replacing the international
access code. For example, +1 908 555 1212 for a number in the United States.
|
![]() | Priv |
Gets or sets the priv.
|
![]() | PrivPrefix |
Gets or sets the priv prefix.
|
![]() | Ssrc |
The Ssrc of this chunk.
|
![]() | Tool |
A string giving the name and possibly version of the application generating the stream,
e.g., "videotool 1.2". This information may be useful for debugging purposes and is
similar to the Mailer or Mail-System-Version SMTP headers. The TOOL value is expected to
remain constant for the duration of the session.
