AA VN MATRIX to a multicast group al decoder CIA VN MATRIX decoder M Vw VN MATRIX decoder 5 a A RTP EE el Any number of decoders be part of the multicast group The source encoder uses RTP to send data to a multicast group The source does not need to know the IP address of any decoders that use that source RTP provides very low latency which is important for video transport Unlike other protocols RTP packets include a time stamp Therefore if packets are received in the wrong order they can easily be sorted into the correct order for display or discarded if the time stamp is out of date However because RTP is a connection less protocol data delivery is not guaranteed Where data packets are lost e g due to excessive network traffic VN MATRIX carefully manages the data stream to minimize any image disruption Page 16 1458GB issue 6 VN MATRIX User Guide Section 1 Introduction Unicast RTP Like Multicast RTP this method uses a real time variation of UDP protocol called RTP This method can be used where the network infrastructure does not support multicast traffic Typically this should be used as a point to point configuration i e single source to single display but can be used for up to four displays SOURCE DISPLAY VN MATRIX RUN Ris VN MATRIX decoder encoder A RTP Encoder se

VN MATRIX units are connected via their own independent network then follow the guidelines below for choosing your IP Addresses However if you intend connecting your VN MATRIX units to an existing network you will need to advise the network administrator and ask them to allocate suitable addresses to you On an independent network you can in theory use just about any addresses you wish However it is generally recommended that you use the Class C format i e from 192 0 0 1 up to 223 255 255 253 Remember that there are two rules for choosing IP Addresses e the network identifier must be the same for each address and e the host identifier must be unique for each address Applying these rules to Class C addresses it can be seen that the first three decimal values of your IP Addresses must all be the same while the last value is used to uniquely identify each device The following is an example of a valid Class C addressing scheme IP Address 208 132 180 41 208 132 180 42 208 132 180 43 NOTE The host identifiers e g 41 42 and 43 in the above example need not be sequential or in any particular order However it is recommended that you group the numbers for simplicity The following is an example of an invalid Class C addressing scheme IP Address 208 132 180 41 192 157 180 42 209 100 123 43 NOTE These are invalid because the network identifier for each address is not the same even though each IP Address i
