- informs the user about the status of an RTP connection. Therefore this menu item is just available if an RTP connection is active at 
. Furthermore system version x.2.0.93 (or later) must be installed.
Note:
x = 2 for CENTAURI and x = 3 for CENTAURI II, MERKII and GANYMED 1102
RTP statistics dialog:
Items:
| • | Input Bit rate (IBR) Bit rate of payload data plus header (usually IEE802.3+IP+UDP+RTP) received by the decoder. This data is measured every second and the results are shown in the red graph in the upper right chart. |
| • | Output Bitrate (OBR) Bit rate of payload data plus header (usually IEE802.3+IP+UDP+RTP) sent by the encoder. This data is measured every second and the results are shown in the green graph in the upper right chart. |
| • | Received Jitter (RCVJ) Jitter of the data received by the decoder according to rfc 3550 (www.ietf.org/rfc/rfc3550.txt). Here jitter describes a variation of the reception period between two adjacent packets. This value can help to set the right reception buffer at item audio delay in menu item Settings/Network. This data is measured every second and the results are shown in the purple graph in the lower right chart. |
| • | Sequence Errors Number of the packets received in the wrong order meanwhile the last minute. At RTP usually some sequence errors can be corrected automatically depending on the set audio delay (menu item Settings/Network). If a sequence error can not be corrected any more it becomes a lost packet (see below). This data is measured every second. |
| • | Lost Packets Number of the lost packets meanwhile the last minute. Without FEC (=Forward Error Correction) any lost packet means a data loss. This data is measured every second. |
| • | Media Delivery Index (MDI) The Media Delivery Index displays the DF (=Delay Factor) and the MLR (=Media Loss Rate) in the format [DF:MLR]. An exact description of the meaning of MDI is described in application note 24 on Mayah Website (www.mayah.com/content/download/pdfs/appnotes/centauri/a_n_e_024.pdf). This data is measured every second. |
| • | Listeners Number of listeners of a RTP connection (but at most RTP connections ‘0’ is displayed). This data is measured every second. |
| • | Input/Output diagram This diagram shows the time characteristics of the input bit rate (red graph) and the output bit rate (green graph). X-axis: seconds Y-axis: kbps Note: This diagram can be saved as a bitmap file or meta file by right mouse click on it. |
| • | Receive Jitter diagram This diagram shows the time characteristics of the receive jitter. X-axis: seconds Y-axis: ms Note: This diagram can be saved as a bitmap file or meta file by right mouse click on it. |
Special mouse features:
| • | Right mouse button: A right mouse click on the ‘Input/Output Bitrate chart’ or ‘Received Jitter chart’ enables to save the referring graph as a bitmap file or a meta file. |
