Page 21: Latency And Gop
AFN Platform – User Manual Latency and GOP ● GOP Type has a direct correlation with Latency performance ● GOP Type options are 1 - IP frames, 2 - IBP frames, and 3 - IBBP frames ● For optimal latency performance GOP type should be set to 1 ●... -
Page 22: Afn Link Guide
AFN Platform – User Manual AFN Link Guide Terminology: ● AFN Link refers to the ability for an AFN Platform to accept a Transport Stream (TS) via TSoIP input and multiplex the incoming service(s) with other TSoIP inputs and the native service(s) that are being encoded by the AFN Video Encoder cards. -
Page 23: Setup Example
AFN Platform – User Manual Setup Example: Link a pair of 8 channel AFN chassis to create a transport stream with 16 services on ASI. ● User sets the output for the Upstream AFN ○ In this example it is 8 services with a mux rate of 85 Mb/s ●... - Page 24 AFN Platform – User Manual ● Available services will be displayed. ● These Network Input services will be available and are preceded by [Net]. ● The Services can be added to the mux to create a 16 channel MPTS.

Page 26: Turn Around Mode
AFN Platform – User Manual Turn Around Mode When AFN is configured for network inputs, they can be turned around to assigned outputs. Turn Around Mode is configured under the Edit Output button on the output pages. When Turn Around Mode is turned ON the user can select what input is to be passed along to the output. Turn Around Mode will just pass TS Mux Rate, Tables, and TSID information. -
Page 27: Srt Guide
AFN Platform – User Manual SRT Guide Terminology: ● Secure Reliable Transport - SRT is an open-source video transport protocol and technology stack that optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks. - Page 28 AFN Platform – User Manual devices on the same fast switch on a LAN, the RTT should be almost 0. Within the Continental US, RTT over the Internet can vary depending on the link and distance but can be in the 60 to 100 ms range. Transoceanic RTT can be 60-200 ms depending on the route.
- Page 29 AFN Platform – User Manual will require exchanging more control packets, as well as resending media packets, and therefore a higher percentage value. ○ **SRT Bandwidth Overhead should not exceed 50% ● Sample Bandwidth Overhead Calculation – As an example, the streaming video is at a bit rate of 1000 kbps and audio at 128 kbps.
