RTP

Real-Time Transfer Protocol (RTP) consists of Events and Thresholds associated with the RTP network protocol for delivering audio and video over IP networks.

ID	*Name*	*Event Error*	*Description*
231	UDP/RTP Protocol Mismatch - expected vs actual	UDP/RTP Protocol Mismatch	When scanning/adding a channel, the input for the transport protocol is set either as RTP or UDP, this event is triggered if the transport protocol is different from the configured.
300	Packet loss - detected by RTP sequence number on any source	RTP Packet loss	Packet loss is based on the RTP sequence counter. This event is triggered when there is a packet loss in any source.
301	Packet loss - detected by RTP sequence number on main source	RTP Packet loss (A)	This event is triggered when there is a packet loss in the main source.
302	Packet loss - detected by RTP sequence number on second source	RTP Packet loss (B)	This event is triggered when there is a packet loss in the secondary source.
303	Source is down (one or both of the 2022-7 sources are down – Video/Audio/Anc)	2022-7 Link Down	This event is a combination of multiple events. It is triggered if the main or secondary content is down.
304	Main Video Flow, High inter-arrival time max value (IAT above threshold)	IAT-max (A)	IAT is the time measured between consecutive packets of the same flow. The time difference between each packet should be constant. If not, the IAT creates a burst on the network, causing the network overloading. If the time difference is greater than configured in the threshold, this event is triggered.
305	Second Video Flow, High inter-arrival time max value (IAT above threshold)	IAT-max (B)	IAT is the time measured between consecutive packets of the same flow. The time difference between each packet should be constant. If not, the IAT creates a burst on the network, causing the network line's overloading. If the time difference is greater than configured in the threshold, and there are multiple flows in this network line, this event is triggered.
306	Audio checksum error	Audio Checksum Error	The checksum error is for AES audio under 2022-6. This event is triggered if the checksum is wrong.
307	Video Flow RTP-PTP offset	Video RTP-PTP Offset	The difference between the PTP clock and the clock value on the RTP headers are measured. This event is triggered if the value is above the configured threshold.
308	Frame alignment to PTP	Misalignment to PTP	This event is valid for 2110-20 and 2022. It is triggered when frame misalignment is above the configured threshold. This event is not affected by the RTP timestamp value.
309	Wrong RTP 2110 Video Payload type	RTP Video Payload error	This event is triggered when the payload type in the RTP header differs from the expected value in the channel configuration.
310	Audio Flow RTP-PTP offset (2110-30/31)	Audio RTP-PTP Offset	Measuring the difference between the PTP clock and the clock value on the RTP headers should be completely aligned. If not, this event is triggered if the value is above the configured threshold.
311	Ancillary Flow RTP-PTP offset (2110-40)	ANC RTP-PTP Offset	Measuring the difference between the PTP clock and the clock value on the RTP headers should be completely aligned. If not, this event is triggered if the value is above the configured threshold.
312	Main Audio Flow, High inter-arrival time max value (IAT above threshold)	Audio IAT-max (A)	Triggers an event for a measured IAT value above the Max configured value.
313	Second Audio Flow, High inter-arrival time max value (IAT above threshold)	Audio IAT-max (B)	Triggers an event for a measured IAT value above the Max configured value.
314	Main Ancillary Flow, High inter-arrival time max value (IAT above threshold)	ANC IAT-max (A)	Triggers an event for a measured IAT value above the Max configured value.
315	Second Ancillary Flow, High inter-arrival time max value (IAT above threshold)	ANC IAT-max (B)	Triggers an event for a measured IAT value above the Max configured value. Triggers an event for a measured IAT value above the Max configured value.
316	Video Source is down (one or both of the 2022-7 sources are down)	Video Link Down	This event is valid only for sources over RTP. It is triggered when the video flow is not active, either one or both. The extra information describes the missing path. (A, B, A+B)
317	Audio Source is down (one or both of the 2022-7 sources are down)	Audio Link Down	This event is valid only for 2110 sources over RTP. It is triggered when the video flow is not active, either one or both. The extra information describes the missing path. (A, B, A+B)
318	Ancillary Source is down (one or both of the 2022-7 sources are down)	Ancillary Link Down	This event is valid only for 2110 sources over RTP. It is triggered when the video flow is not active, either one or both. The extra information describes the missing path. (A, B, A+B)
322	Wrong RTP 2110 audio Payload type	RTP Audio Payload error	Triggered when the payload type in the RTP header differs from the expected value in the channel configuration.
323	Wrong RTP 2110 ancillary Payload type	RTP ANC Payload error	Triggered when the payload type in the RTP header differs from the expected value in the channel configuration.
