MGW Diamond
Multi-Channel HEVC and H.264 Portable Encoder
User Manual, Version 1.6

NOTE:
To minimize the end-to-end latency, the initial delay can be reduced to lower values. Such change may
impact video quality or encoder bitrate regulation. It is then recommended to allow either a higher bitrate
or a higher MuxRate Overhead.
•
Maximum Delay
(ms)
-
Maximum duration threshold before Access Units (AU‘s) are
multiplexed together. This setting minimizes high bitrate variations (range is 1-1000).
•
Latency Monitoring
–
Enable to allow end-to-end latency monitoring when decoding the
stream with MGW Ace Decoder. Latency can be monitored within MGW Ace Decoder web
interface or via HTTP command.
If enabled, Timecode input is not captured from SDI input anymore.
•
To ensure accurate Latency Monitoring, system date must be synchronized to an NTP server. Ensure to
correctly configure the NTP server in System/Date and Time section on both MGW Diamond and MGW Ace
Decoder.
•
When Latency Monitoring is enabled, SDI timecode (VITC) is no more embedded.
•
PMT PID
–
A special identifier of the PMT within the transport stream. The PMT (Program
Mapping Table) describes the various services and their PIDs within the transport stream.
Default: 1240.
•
Video PID
–
A unique identifier of the video service within the transport stream. Only a
single video service is available per a transport stream. Default: 1241.
•
PCR PID
–
A special identifier of the PCR data within the transport stream. The PCR
(Program Clock Reference) data contains clocking information for synchronization between
various services. Default: 1241.
•
Audio PID
1
–
A unique identifier of the first audio service within the stream. Up to two
Audio services can be available per a transport stream. Default: 1242.
•
Audio PID
2
(not available)
–
A unique identifier of the second audio service within the
stream. Up to two Audio services can be available per a transport stream. Default: 1243.
•
KLV PID 1
–
A unique identifier of the KLV (Key Length Value) metadata service within
the transport stream. Default: 497.
•
KLV PID 2
(not available)
–
A unique identifier of the KLV (Key Length Value) metadata
service within the transport stream. Default: 498.
•
KLV Sampling
–
Check the box to sample the KLV frames according to the encoding
framerate configured. KLV frames are sampled and synchronized with each encoded frame
and transmitted over UDP TS according to MISB 0605.6/0604.4 and STANAG4609
