Adding UDP Outputs

this enables the broadcaster to send a udp stream the udp stream is not protected by the zixi protocol the udp streams can be one of the following types udp – plain udp rtp – real time transport protocol rtp + smpte 2022 fec smpte 2022 standard with forward error correction to create a udp output in the zixi broadcaster outputs page, click + new output the new output window is displayed new udp output type in the unique identifier for this output in the output name select an input stream to be made available on this output from the drop down list select the show in matrix check box to display this stream in the matrix (see using the matrix docid\ bp6mo9f2qbxmu6gurkog4 ) default selected select the log this stream checkbox if you would like to generate event logs for this output select udp specify the output parameters (see output stream parameters table docid\ abswejdsg6zgiqpwvouc1 below) in the host field, specify the ip address or url of the stream destination in the port field, specify the port of the destination if you want to specify billing codes to identify and differentiate traffic on a zixi broadcaster for billing purposes, select this checkbox ( see output stream parameters table docid\ abswejdsg6zgiqpwvouc1 below) if you want to remux the stream to cbr (used for professional irds) in order to avoid bandwidth waste or add null packets and adjust the stream clock (pcr) in order to make the stream cbr, select remultiplex/pad and configure the respective parameters ( see output stream parameters table docid\ abswejdsg6zgiqpwvouc1 ) click ok output stream parameters table parameter description output parameters host specify the destination ip address or url port specify the target udp port ttl specify the time to live (ttl) used mainly to limit the range (or “scope”) of a multicast transmission leaving it blank uses the default value specified by the operating system 204b ts packet enable this option if the stream has an mpeg ts that uses 204 bytes packets this will allow the udp packets to be aligned with mpeg ts packets smoothing \[mms] enables transmission of the output at the correct rate required when the receiving device is sensitive and can’t lock onto the stream (in such a case, the recommended latency is 100 1000 ms) rtp enables the use of the real time transport protocol smpte 2022 fec disables the fec or specifies the type of fec matrix to d1/ d2 this setting can be modified without interrupting an existing stream in the smpte 2022 fec standard, 1 d and 2 d parity codes are systematic fec codes of decent complexity that provide protection against bursty or random losses to enable smpte 2022 fec (forward error correction) select one of the following parity options from the drop down menu 1d (single dimension fec) smpte 2022 1d can fix a problem in one packet per row this means that the number of rows specified should consider the packet loss rate the shorter the row, the more error resilience can be achieved at the expense of the bitrate level however, longer rows increase the delay that the fec will add it is recommended to select this option when the packet loss is sporadic the stream will occupy the source port and two ports above it (e g , if the source port is 8988, it will occupy 8990) 2d smpte 2022 2d uses a table of packets, which includes rows and columns this option is more error resilient, but it increases the delay by (row column) packets and increases the bitrate with r+c packets per each table of r c packets it is recommended to select this option when packet loss is bursty the stream will occupy four ports above (e g , if the source port is 8988, it will occupy 8992) bind to ip select from the drop down list the local ip address to be used for this output, or select any to enable any ip to be used local port specify from which local port to source the stream, if desired (instead of randomly chosen by the operating system) billing codes billing codes are used to identify and differentiate traffic on a zixi broadcaster for billing purposes when a billing code is added to a source or target, zixi can track the traffic on that broadcaster input or output separately from other inputs and outputs on the same broadcaster billing codes are created by zixi personnel on the zixi customer portal for a particular organization billing code enter the billing code that corresponds to this stream the relevant billing can be obtained from the organization that received the billing code from zixi billing password enter the password that corresponds to this billing code remultiplex/pad select this checkbox to enable remuxing from vbr mpeg ts to mpeg ts cbr (used for professional irds) or padding with null packets mode select one of the following pad – adds null packets and adjusts the stream clock (pcr) in order to make the stream cbr remultiplex performs demux >mux and rebuilds the stream according to the parameters below target bitrate \[kbps] specify the cbr bitrate to target for the padded stream (pad) or a re multiplexed stream (remultiplex) pcr interval \[ms] select the frequency at which the program clock reference is inserted into the outputs transport stream default 90 buffer size \[ms] specify the maximal difference between dts and pcr relevant only for remultiplex mode no null packets select this option to re multiplex the stream to cbr but remove the null packets in order to maintain a low bitrate enable decryption select this checkbox to decrypt an encrypted stream decryption type if the stream has been encrypted, you can decrypt it through the output by selecting this checkbox and specifying the type of encryption that was used select automatic to decrypt a stream that has been encrypted using automatic encryption only if the stream has not been encrypted, select none (default) important notice if the stream has been encrypted, you must decrypt it in the output decryption key if the decryption type includes a key, enter the key to decrypt the stream during output advanced mode the fields discussed below are optional and available only in advanced mode to enter advanced mode add the url parameter ?advanced=1 to the zixi broadcaster url in your browser and press enter/return to reload the page note the advanced mode settings are generally intended for advanced users and special cases if you do not understand the settings, you should probably accept the default values general latency offset \[ms] specify the additional buffering time in milliseconds increasing this value can improve stream stability in unstable network conditions, but will increase end to end delay default 0 ms output parameters specify the differentiated services code point (dscp) value for the stream this 6 bit value (ranging from 0 to 63) is embedded within the ip header of the network packets to classify the traffic type and define its priority level across the network routing infrastructure ecn don't fragment max packet payload buffer fill time \[ms] remultiplex/pad restamp enable ifb/talkback port specify the port to listen on this port must be open on all firewalls between the zixi broadcaster and other devices it is communicating with
