Enable Forward Error Correction (FEC) on a Stream
To enable FEC on a stream:
1. Navigate to
Encoder Configuration
>
Streams
.
2. Click the
Enable FEC
checkbox. Complete the FEC fields that appear as needed.
Forward Error Correction (FEC) is available for MPEG2TS streams only. FEC is configured
at the stream level and at the transmitter level. This topic explains how to configure FEC at
the stream level only. To configure it at the transmitter level see the Enable Forward Error
Correction (FEC) on a Transmitter topic.
FEC is a type of digital signal processing that improves data reliability by introducing a
known structure into a data sequence prior to transmission or storage. This structure enables
a receiving system to detect and possibly correct errors caused by noise and interference. As
the name implies, this coding technique enables the decoder to correct errors without
requesting retransmission of the original information. For detailed information about
VBrick's implementation of FEC see the Forward Error Correction (FEC) Theory of
Operation topic.
Overhead (%)
Controls the padding packet overhead as a percentage. Read-only
unless "Custom" Transport Stream Mode defined above. Range: 1–
500. See Advanced Transport Stream Settings for more information.
PTS-PCR Gap
(ms)
Controls the PTS-PCR Gap delay in milliseconds. Read-only unless
"Custom" Transport Stream Mode defined above. Range: 50–2000.
See Advanced Transport Stream Settings for more information.
Video PID
Range: 4–8190. Default = 33.
Audio PID
Range: 4–8190. Default = 36.
Metadata PID
Range: 4–8190. Default = 35.
PCR PID
Range: 4–8190. Default = 34.
PMT PID
Default = 66.
PCR Rate
• 10 per second (default).
• 25 per second.
Encryption
Enable Encryption
Note:
If using FEC you may choose to
Enable UDP Checksums
and you will also need
to set the
Max Packet Size
to 1500 bytes or less. Both of these parameters are located
on the Encoder Configuration > Programs page.
