NODESTER
Device Configuration
Nodester enables users to target a desired outcome (high quality or low latency) to suit their
network properties through the configuration of the connected Nodestream devices. To
successfully achieve this, it is important to have a solid understanding of resolution, framerate,
bitrate and latency and their relationship with each other.
•
Resolution
Number of pixels contained in each frame
•
Framerate
Number of frames per second
•
Bitrate
Amount of data per second
•
Latency
Time taken for data to be sent from the source to the destination
The technical limits of the connected network needs to be considered when configuring a
connection as this determines the maximum bitrate available and initial latency. A target bitrate
cannot be achieved if the network cannot support it.
Below are examples of setting relationships and how they may impact the connection
Resolution
•
A higher resolution requires more bitrate, while a lower resolution requires less bitrate
•
Increase resolution if higher quality is desired
•
Decrease resolution if lower latency is desired
Frame-rate
•
A higher framerate requires more bitrate, while a lower frame-rate requires less bitrate
•
Increase framerate if a smoother stream is desired
•
Decrease framerate if higher image quality or lower latency is desired
Bit-rate
•
Bitrate live on a decoder shows the current bitrate utilisation of the connection, adjust the
target bitrate to suit. For best results, set target bitrate to 80% of available bitrate
•
If the target bitrate is greater than the bitrate live, stream quality will be affected
Latency
•
Increasing latency allows data more time to correctly transfer from an encoder to a decoder
•
Increase latency if higher quality is desired
•
Decrease latency if less delay is desired
•
Devices must be online to allow configuration. Some setting may only be available when the device
is connected to another.
•
Audio connections will be affected if all available bandwidth is consumed by video streams
