general id the unique (alphanumeric) name of the zixi broadcaster server typically host name this field is editable machine local time shows the current time for the machine web server port the port number of the web server administration you can configure this parameter to any legal port number which is supported by your firewall default 4444 admin user name the user name of the administrator the administrator is authorized to modify all parameters in the system as well as manage all the outputs and inputs on the server admin password the password of the administrator enable read / write

select this checkbox to enable an "observer" user this type of user can read throughout all of the screens you can modify the user name (i e , enter another name instead of observer) and password enable https administration enables secure https connection to the server for administration enabling https requires the relevant certificates and private keys to enable https, click on the checkbox and upload the required files root folder displays the configured root folder you can modify the root folder by modifying the broadcaster info xml, which is located in the zixi broadcaster installation folder (\<broadcaster installation folder>\zixi\broadcaster\\) tr101 analyzer mode select the mode in which the tr101 analyzer will operate none – no tr101 analysis atsc – based on the advanced television systems committee recommendations dvb – based on the digital video broadcasting specifications enable audio levels in matrix select this option to enable audio level display in matrix view when not selected, the audio levels display will be turned off https and dtls streaming certificate to enable dtls automatic encryption, click on the checkbox and upload the required files note if you want to create a self signed certificate for a standalone broadcaster, see the section below on creating a self signed certificate certificate uploaded (for dtls enabled) if no certificate has been uploaded, click upload and navigate to the file location note this is the same certificate as the https certificate private key uploaded (for dtls enabled) if no private key has been uploaded, click upload and navigate to the file location private key pasphrase (for dtls enabled) enter the private key passphrase for your dtls account ssl setup status displays the status of the ssl certificate upload process incomplete – the ssl setup process is incomplete ok – the ssl setup process is complete server ports port the port that is used to handle traffic the port direction and type are determined by selecting the relevant checkboxes adding additional ports may be necessary when there is a chance that the isp will block a certain port click '+' to add additional ports ip enter the ip address of the nic interface the default enables any ip address to use high performance networking, select a blue colored ip address push input select this option if you want to enable push input through this port pull output select this option if you want to enable pull output through this port dtls select this option to activate dtls automatic encryption of the streams + (add ports) click + to add additional ports note for each port, you can select whether or not to activate dtls encryption this enables streaming of non encrypted streams on one port and encrypted streams on a separate port limits select to configure thresholds for generating an alarm cpu \[%] the cpu utilization threshold if this limit is exceeded, the cpu indicator at the top of the screen will appear in red, and an alarm will be generated in the event log default 90 memory \[%] the memory utilization threshold if this limit is exceeded, the memory indicator at the top of the screen will appear in red, and an alarm will be generated in the event log default 90 max disk quota \[%] the maximal percentage of the disk capacity that can be used default 85 gpu \[%] the gpu utilization threshold default 0 input bandwidth \[kbps] bandwidth utilization threshold for input streams default unlimited output bandwidth \[kbps] bandwidth utilization threshold for output streams default unlimited 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 menu enable audio levels in matrix checkbox count per pid statistics on push/pull inputs checkbox pull outputs stream thinning latency \[ms] creating a self signed certificate there are various ways to obtain ssl/tls certificates, but for a standalone broadcaster, you can also create a self signed certificate using openssl openssl may already be installed on your system, but if not, you can see a list of av available binaries to install at https //github com/openssl/openssl/wiki/binaries https //github com/openssl/openssl/wiki/binaries during the creation of your certificate, you will be prompted for the following information a passphrase for the certificate be sure to remember what it is! the two letter code for your country (such as us or fr) if you don't know the code, you can look it up at https //knowledge digicert com/general information/ssl certificate country codes https //knowledge digicert com/general information/ssl certificate country codes the full state or province name within that country (such as massachusetts) the locality name, typically a city such as boston organization name, such as zixi organizational unit name, such as documentation your name or a fully qualified domain name (fqdn), such as zixi com your email address once openssl is installed, you can create a certificate by running a command like this // sample command see openssl help for options // note that the pem files will be created in the directory where you run this command openssl req x509 newkey rsa 2048 keyout selfsigned key pem out selfsigned cert pem after the pem files are created, you can upload them and enter the passphrase in the broadcaster settings as described above
