3 FEC (Forward Error Correction) Functions
The FEC (Forward Error Correction) function can correct errors on streaming data.
With this function, even when loss or error of data occurs during distribution, they
are corrected so as to play back the content properly. In order to use the FEC
function, the stream server also has to support the FEC function.
The FEC settings for the MediaEdge-STB3 can be assigned using the Web console
([Local Settings] > [Network] > [FEC mode]).
- The default FEC setting is [Enable].
- When the FEC is set to [Enable], the MediaEdge-STB3 checks whether the
delivered stream supports the FEC mode. If it does, the MediaEdge-STB3 starts
playback using the FEC mode. If the delivered stream does not support the FEC
mode, the MediaEdge-STB3 starts playback without using the FEC mode.
- When the FEC is set to [Disable], MediaEdge-STB3 always starts playback
without using FEC mode.
Warning:
- The maximum bitrate to properly execute playback in FEC mode is 15Mbps when the
TS packets stored in RTP is between 7 and 31. (25Mbps if the TS packets stored in
RTP is larger than 32)
- When FEC mode is enabled, longer playback delay may occur depending on the
settings of the stream server (i.e., ES packets stored in RTP, FEC parameters, etc.)
Setting a higher value to TS packets or FEC parameters increases the burden on
internal memory, consequently, causing playback errors.
[Stream server that supports FEC mode]
