ProHD BR-EN900 HEVC Encoding and Streaming ApplianceUser Manual, Version 2.2 43Error Correction SettingsZixi™The Zixi protocol supports two modes: Zixi Broadcaster Server and Point-to-point streamingdirectly from the JVC encoder to the JVC decoder appliance. Zixi sessions can be protected by apassword. Protected sessions ensure that only authorized encoders/decoders participate in thesesessions.• Password: If a password was set on Zixi™ server, enter the password for streaming. Ifno password was set on the Zixi™ server, no password is required. When connectingdirectly (point-to-point) to a decoder, a password is not applicable.• Latency: Enter a latency value in milliseconds to be used for correcting errors. Theminimal latency to be used must be higher than 3 times the RTT value (Round Trip Time)between the encoder and the targeted decoder. RTT value is available in Zixi ChannelStatistics window after the Zixi channel has been started. Additionally, higher latencyincreases tolerance to network errors (range 0-6000 milliseconds). The actual errorcorrection rates depend also on the stream bit-rate. On average, 500ms latency yieldsprotection of up to 6% of network errors. 6000ms latency yields protection of up to 30%of network errors.• When using a Zixi latency lower than 500ms, FEC data protection is enabled resulting in an increased total outputbitrate up to 50%. Ensure the transmission link bandwidth is dimensioned for such bitrate.• If Zixi latency is set to 0, no data protection is achieved. Use this value to analyze the quality of your transmissionlink. Transmission link statistics are reported within the Zixi Statistics Channel (Dashboard).Check the Zixi Statistic information window to monitor the packet loss of the transmissionlink used and set the latency accordingly.• Enable ABR (Adaptive Bitrate): Select the check box to allow either JVC decoder orBroadcaster Server to automatically change the encoding bit-rate while streaming. Whenselected, the channel total bit-rate will automatically be optimized, based on networkperformance and statistics from the Zixi stream recipient, to ensure smooth, artifacts-freeplayback.• Minimum Bit-Rate: Set the minimum bit-rate allowed while in dynamic mode• Maximum Bit-Rate: Set the maximum bit-rate allowed while in dynamic mode.
