==Audio and video payload types==

The technical parameters of payload formats for audio and video streams are standardised.{{Ref RFC|3551}}

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:.

* {{Sum RFC|31903551|ref=yes}}

* {{Sum RFC|4856|ref=yes}}

Additional payload formats and payload types are defined in the following specifications:

* {{Sum RFC|3190|ref=yes}}

* {{Sum RFC|6184|ref=yes}}

* {{Sum RFC|3640|ref=yes}}

* {{Sum RFC|6416|ref=yes}}
