What is RTCP value?

What is RTCP value?

This 32-bit value uniquely identifies each member in a session. Report blocks: Report block is the standard terminology for an RTCP reception report. RTCP [1] encourages the stacking of multiple report blocks in Sender Report (SR) and Receiver Report (RR) packets.

What is RTCP packet?

RTCP is the Real-time Transport Control Protocol, which may be used as a lightweight companion to RTP to convey a number of statistics and other information about an RTP flow between recipients and senders.

What is RTCP RR?

The data transport is augmented by a control protocol (RTCP) to allow monitoring of the data delivery in a manner scalable to large multicast networks, and to provide minimal control and identification functionality. RTP and RTCP are designed to be independent of the underlying transport and network layers.

Is RTCP UDP or TCP?

Protocol dependencies UDP: Typically, RTCP uses UDP as its transport protocol. RTCP does not have a well known UDP port. Instead, the ports are allocated dynamically and then signaled using a different protocol such as SDP and H245.

What is the RTCP protocol used for?

RTCP is used in voice over IP (VoIP) and Internet Protocol Television (IPTV), streaming media and video conferencing. RTCP carries statistical and control data, while RTP delivers the data. RTCP statistics typically include the number of bytes sent, packets sent, lost packets and round trip delay between endpoints.

How does RTP and RTCP work?

RTP is the transport protocol for real-time data. It provides timestamp, sequence number, and other means to handle the timing issues in real-time data transport. RTSP is a control protocol that initiates and directs delivery of streaming multimedia data from media servers.

Does RTP use TCP or UDP?

RTP is generally used with a signaling protocol, such as SIP, which sets up connections across the network. RTP applications can use the Transmission Control Protocol (TCP), but most use the User Datagram protocol (UDP) instead because UDP allows for faster delivery of data.

Does RTCP use UDP?

RTCP uses a temporary port. It must be an odd-numbered port. It uses UDP port number which is the next higher odd number and that follows the port number which selected for RTP.

Can RTP use TCP?

RTP applications can use the Transmission Control Protocol (TCP), but most use the User Datagram protocol (UDP) instead because UDP allows for faster delivery of data.
