Smart Preset Bandwidth Testing

After you press a Smart Preset button such as Talking Head, Action, Low Latency, or Reliable (not all products have all these options), the Automatic Bandwidth Negotiation process sends signals to the Streambox Decoder, and receives signals in return, measuring the speed and return time of the data exchanged in order to find out much bandwidth the Encoder can deliver while still giving low-latency performance. ABN cycles through numerous possible settings for the LDMP Transport to find a setting that exceeds a Minimum threshold for bitrate, and falls below a maximum threshold for latency.

ABN typically cycles through about 5 possible levels of settings at most. More typically only 1 or 2 cycles is needed.

NOTE: It is recommended that the user does not press the Accept button unless the Encoder is being used under known, static network conditions.

The ABN period is 45 seconds by default, but that may be changed in the ABN settings. Streambox does not recommend that you change the ABN period unless you are absolutely confident that you can manually select the best settings using the Next and Accept buttons.
