Question

What could be the likely cause when VIDEOJET decoder 7000 (VJD-7513) displays ‘Error Discontinuity in network stream!’ message?

Hardware:

• VIDEOJET decoder 7513 operating on firmware version 10.40.0061

Symptom: “Error: Discontinuity in network stream!” appears randomly on the monitor/s connected to the VIDEOJET Decoder 7000 (7513).

Answer

This message is shown when there is video packet loss on the streaming camera.

If the camera is streaming in UDP mode and there is packet loss during the transmission, this message will appear on the video display of the decoder as it could not decoded the stream due to missing packets.

If the camera is streaming in TCP mode and there is packet loss during the transmission, the camera will re-attempt to transmit the missing packet again if it is a minor network issue.

Therefore, you should request to the network team to check the logs on the network switch port and find out why is network packet lost between camera network port and decoder network port.
