| Extended RTP Header for Sent ROI | O | This information element requests the MRFP to pass on the ROI extended RTP header for carriage of predefined and/or arbitrary ROI information as defined by RFC 5285 and TS 26.114. | ||
| Predefined ROI Sent | O | This information element requests the MRFP to support the RTCP feedback message capability for "Predefined ROI" type toward the ROI-sending client, expressed by the parameter "3gpp-roi-predefined", as described in TS 26.114. | ||
| Predefined ROI Received | O | This information element requests the MRFP to support the RTCP feedback message capability for "Predefined ROI" type toward the ROI-receiving clients, expressed by the parameter "3gpp-roi-predefined", as described in TS 26.114. | ||
| Arbitrary ROI Sent | O | This information element requests the MRFP to support the RTCP feedback message capability for "Arbitrary ROI" type toward the ROI-sending client, expressed by the parameter "3gpp-roi-arbitrary", as described in TS 26.114. | ||
| Arbitrary ROI Received | O | This information element requests the MRFP to support the RTCP feedback message capability for "Arbitrary ROI" type toward the ROI-receiving clients, expressed by the parameter "3gpp-roi-arbitrary", as described in TS 26.114. | ||
| Notify CLUE Message Received Event | O | This information element requests a reporting of the received CLUE message. | ||
