Decoding Zixi and Pro-MPEG Streams (HEVC and H.264)
Zixi™ protected streams and Pro
-MPEG protocol are not supported by open source free software
players such as VLC or MPC.
You may use VITEC MGW Ace Decoder (HEVC/H.264), VITEC MGW D265 Decoder (HEVC/H.264)
or Zixi Broadcaster. Pro-MPEG streams may be decoded by 3rd party decoders that support
SMPTE-2022 protocol.
Setting and Playing Zixi™ Channels
To send Zixi streams to the Zixi Broadcaster Server:
In the Channels page Target section:
1.
Enter the Zixi Broadcaster server's
IP address
and
Port
(see Target table above).
2.
Click
Error Correction Settings.
The
Zixi Settings
window opens. Enter the following
parameters:
•
Password:
Enter the password for streaming to a Zixi™ receiver (Server or a Stand
-alone
decoder).
NOTE
:
The password you enter must be identical to the password entered in the Zixi Broadcaster Web interface).
•
Latency:
Enter a latency value in milliseconds to be used for correcting errors. The
minimal latency value must be three times higher than the RTT (Round Trip Time) value
that is used between the encoder and the targeted decoder. RTT value is available in Zixi
Statistic window (see
The Dashboard Page
(on page 25) after the Zixi channel has been
started.
Additionally, higher latency increases tolerance to network errors (range 500-6000
milliseconds). The actual error correction rates depend also on the stream bit-rate. On
average, 500ms latency yields protection of up to 6% of network errors. 6000ms latency
yields protection of up to 30% of network errors.
Check the Zixi Channel Statistic window (see
The Dashboard Page
on page 25) to monitor
the packet loss of the transmission link used and set the latency accordingly.
•
Enable Dynamic Bit-rate Control:
Select the check box to allow either VITEC decoder
or Broadcaster Server to automatically change the encoding bit-rate while streaming.
