An Introduction to RTCP (Real-Time Transport Control Protocol)

What does it do?

If you are looking for the answers to the above questions, you come to the right place.

This post provides details about RTCP.

Now, it’s possible for you to continue to read this post.

What Is RTCP?

RTCP refers to Real-Time Transmission Control Protocol.

It is a protocol that works withReal-Time Protocol(RTP) to monitor data transmission on large multicast networks.

RTCP transmits statistics and control data, while RTP transmits data.

RTCP statistics typically include bytes sent, packets sent, packets lost, and round-trip latency between endpoints.

Such information can be sourced for adaptive media encoding (codec) and detection of transmission failures.

Allows non-intrusive session quality monitoring if the session is transmitted over a multicast online grid.

RTCP provides canonical endpoint identifiers (CNAMEs) to all session participants.

CNAMEs establish unique identities of endpoints across utility instances (multiple uses of media tools) and third-party monitoring.

Provides session control functionality.

RTCP is a convenient way to contact all session participants, whereas RTP itself is not.

RTP is only transported by media sources.

Receiver Report

Passive participants are those that do not send RTP packets and use Receiver reporting for them.

This report is used to inform senders and other receivers about the quality of service.

After the receiver receives the RTP message, these absolute timestamp details help the receiver to synchronize processing.

This is very important in audio-video transmission to find relative timestamps.

Source Description Message

Sources send source description messages at regular intervals to provide some additional information about themselves.

It contains details about the source name, its mail ID, contact number, or source controller.

Bye Message

To kill the stream, the source sends a message called a goodbye message.

Feeds are used to announce departures from meetings.

This message is a direct announcement from other sources stating that there is no source.

It can be used to combine different media files.

It can be used to extend the bang out of utility.

Here is all the information about the RTCP.
