One of the elements that SDP uses is called UTF-8 which helps to detail the use of characters in machine language.

SDP helps to specify the broadcast methods along with the format and time definition of the session. SDP applies to session announcement, session invitation and different aspects of session initiation for multimedia sessions. The IETF describes SDP as general protocol applied to sets of multimedia senders and receivers.

Much of the technique for this type of conferencing involves multicasting, and SDP helps to provide consistent standards and guidelines to these types of technology uses.
