ASI

the asi screen is used to configure the asi interface when there is an asi card in the machine you can use this screen to reverse the direction of the ports on the asi card the port numbers should correspond to the port numbers on your asi card field description asi output stuffing select this checkbox to achieve cbr (constant bitrate) by padding the asi stream with ts null packets asi output pll select this checkbox to enable a phase locked loop a phase locked loop or phase lock loop (pll) is a control system that generates an output signal whose phase is related to the phase of an input signal when selecting this option, the system will adjust the bitrate that is sent according to the fullness rate of the output buffer asi fix time select this checkbox to adjust input timestamps to local machine time initial buffer time \[ms] to avoid underflows, specify the output buffer size that will be filled before starting the transmission read buffer size \[b] specify the input read buffer to fill, before passing data to the application larger buffer size should be specified for higher bitrates; smaller buffer size will be more responsive and smoother in lower bitrate streams reversing the directions of the ports to reverse the direction of the ports from the settings page of the zixi broadcaster, click asi on the left hand side the various asi settings are displayed click the desired reset button to the right of the port that you want to reverse a confirmation window is displayed with the notification that the service must first be restarted before the direction is reversed field description available ports name specifies the port number used by the asi protocol data direction specifies the direction of the data being transmitted by the asi protocol
