ZEC Adding RIST Streams

this enables the broadcaster to receive an rist stream rist seeks to provide reliable, high performance media transport by using udp at the transport layer to avoid the inefficiencies of tcp, then layering on top forward error correction and retransmits to add the reliability inherently absent from udp zec supports rist streams from any compliant rist device zixi supports the following rist profiles simple profile – the rist simple profile provides best in class packet protection, as well as support for multi link bonding and seamless switching main profile – the rist main profile builds upon the features of the simple profile to provide backwards compatibility, while opening the door for additional features, including the use of industry standard dtls with a variety of available cyphers to ensure the most up to date protection, while being flexible to accommodate local legal regulations support for pre shared keys is also included, which makes rist main profile compatible with one to many environments such as satellite or multicast distribution contact your zixi representative to learn more about interoperability testing between zec and 3rd party devices more details about rist can be found at www rist tv http //www rist tv/ to add a rist stream in the zec navigation menu, click the inputs tab in the menu bar, click new input the add a new input stream window is displayed enter the unique stream id note this must be identical (case sensitive) to the stream name configured in the sending zixi broadcaster or mediaconnect select the maximum concurrent connections to this stream from the max outputs drop down list default unlimited select the show in matrix check box to display this stream in the matrix (see zec using the matrix docid\ ofxethpsuo9eimqpwfzea ) default selected select rist for the input stream options will vary depending on whether you select the main profile or the simple profile rist main profile inputrist simple profile input specify the stream parameters (see the input stream parameters table docid\ ra5 syzb5mvqa5l1qiv3d below) if you want to enable encryption , select this checkbox (see input stream parameters table docid\ ra5 syzb5mvqa5l1qiv3d ) for more information, see zec encrypting an input stream docid\ qern0zffbaztl vrw4rn if you want to configure the recording parameters , specify them in the respective fields (see input stream parameters table docid\ ra5 syzb5mvqa5l1qiv3d ) click ok the “input added” message appears at the top of the screen the rist stream is added to zec and now appears in the list of streams available in the zec inputs ui input stream parameters table parameter description stream parameters profile select one of the following rist profiles that matches the input stream simple profile (default) main profile simple profile parameters local port specify the port to listen on this port must be open on all firewalls between the zec and other devices it is communicating with multicast ip if multicast, type the multicast ip address (or leave blank in the case of unicast) ssm source specify the source ip for a source specific multicast remote port specify the remote port in the source rist device default 0 (any port) type select one of the following protocol types from the drop down list rtp rtp + smpte 2022 fec bind to ip select from the drop down list the local ip address to be used for this input, or select any to enable any ip to be used max bitrate \[kbps] specify the maximum expected bitrate for memory allocation recommended 2x the actual bitrate, which will prevent buffer overruns (especially with vbr streams) default 8000 note – overflows will typically occur when the max bitrate isn’t sufficient max latency \[ms] specify the maximum latency of the stream in milliseconds default 1000 dejitter buffer \[ms] a buffer size used to de jitter rtp and udp inputs for rtp, packet timing is fixed according to packet arrival times and rtp timestamps for udp, dejittering is only based on arrival times default 0 assuming that the timestamps in the rtp are accurate, this feature is helpful when the encoder generates an accurate timestamp on the stream, but the arrival is jittery/bursty in case of jitter, specify a higher value than the rtp input jitter to view the jitter level of the input stream, create the input and select it on the inputs screen;
