DICOM PS3.22 2021e - Real-Time Communication

6.2.2 RTP Payload

The RTP Payload for audio and video Flows shall follow [SMPTE ST 2110-20] and [SMPTE ST 2110-30], respectively.

The RTP Payload for DICOM Metadata Flows (audio, video and rendition) shall follow [SMPTE ST 2110-10].

The RTP Payload for DICOM Metadata Flows consists of a DICOM dataset compliant with real-time communication.

The DICOM dataset is made of three parts:

Note

The receiver cannot process information received from a sender until it receives DICOM Metadata including the static part, so it has to be sent at least every second in order to avoid a longer wait by the receiver when "connected" to a sender.

The transmission rate of DICOM audio flows will be typically of the range of 48kHz. The transmission rate of DICOM video flows will be typically of the range of 60Hz. The transmission rate of the DICOM Rendition Metadata Flow shall be at least 1Hz. It may be appropriate to use a higher frequency if there is a need for tight synchronization of associated Flows from a device (e.g., two videos of a stereo pair).
