The Real-time Transport Protocol (RTP) specifies a general-purpose data format and network protocol for transmitting digital media streams on Internet Protocol (IP) networks. The details of media encoding, such as signal sampling rate, frame size and timing, are specified in an RTP payload format. The format parameters of the RTP payload are typically communicated between transmission endpoints with the Session Description Protocol (SDP), but other protocols, such as the Extensible Messaging and Presence Protocol (XMPP) may be used.
Audio and video payload types[edit]
- This memorandum describes RTP, the real-time transport protocol. RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services.
- Oil well head systems consume two-thirds of the electricity used by the industry in general, ensuring significant savings. The use of oil well head systems is a trend in the industry worldwide, as well as in.
- It can be used for media-on-demand as well as interactive services such as Internet telephony. R TP was developed by the Internet Engineering Task Force (IETF) and is in widespread use. The RTP standard actually defines a pair of protocols: R TP and R TCP.
RFC 3551, entitled RTP Profile for Audio and Video (RTP/AVP), specifies the technical parameters of payload formats for audio and video streams.
The standard also describes the process of registering new payload types with IANA; additional payload formats and payload types are defined in the following specifications:
- RFC3551, Standard 65, RTP Profile for Audio and Video Conferences with Minimal Control
- RFC4856, Media Type Registration of Payload Formats in the RTP Profile for Audio and Video Conferences
- RFC3190, RTP Payload Format for 12-bit DAT Audio and 20- and 24-bit Linear Sampled Audio
- RFC6184, RTP Payload Format for H.264 Video
- RFC3640, RTP Payload Format for Transport of MPEG-4 Elementary Streams
- RFC6416, RTP Payload Format for MPEG-4 Audio/Visual Streams
- RFC2250, RTP Payload Format for MPEG1/MPEG2 Video
- RFC7798, RTP Payload Format for High Efficiency Video Coding (HEVC)
- RFC2435, RTP Payload Format for JPEG-compressed Video
- RFC4587, RTP Payload Format for H.261 Video Streams
- RFC2658, RTP Payload Format for PureVoice Audio Video
- RFC4175, RTP Payload Format for Uncompressed Video
- RFC7587, RTP Payload Format for the Opus Speech and Audio Codec
Payload identifiers 96–127 are used for payloads defined dynamically during a session. It is recommended to dynamically assigned port numbers, although port numbers 5004 and 5005 have been registered for use of the profile when a dynamically assigned port is not required.

Well, after years of rejecting offers from developers to buy the site, the owners have finally made the decision to sell. The Facebook post also noted that Covid-19 has impacted business operations.
Applications should always support PCMU (payload type 0); previously, DVI4 (payload type 5) was also recommended, but this was removed in 2013 by RFC 7007.

- ^The 'clock rate' is the rate at which the timestamp in the RTP header is incremented, which need not be the same as the codec's sampling rate. For instance, video codecs typically use a clock rate of 90000 so their frames can be more precisely aligned with the RTCP NTP timestamp, even though video sampling rates are typically in the range of 1–60 samples per second.
- ^Although the sampling rate for G.722 is 16000, its clock rate is 8000 to remain backwards compatible with RFC 1890, which incorrectly used this value.[1]
- ^Because Opus can change sampling rates dynamically, its clock rate is fixed at 48000, even when the codec will be operated at a lower sampling rate. The
maxplaybackrate
andsprop-maxcapturerate
parameters in SDP can be used to indicate hints/preferences about the maximum sampling rate to encode/decode. - ^For aptX, the packetization interval must be rounded down to the nearest packet interval that can contain an integer number of samples. So at sampling rates of 11025, 22050, or 44100, a packetization rate of '4' is rounded down to 3.99.
