Error Resilience
–
This setting defines HEVC encoder strategy to protect the stream from
being heavily corrupted at the decoder output when an error occurs in the transmission
link (Packet loss, Packet Corruption,…). Three steps are available: Off / Medium /High.
This mode can be used when error correction at the transport level (Zixi or Pro-MPEG)
cannot be activated due to latency concerns.
•
Closed Captioning
–
Enable CC
–
Closed captions are captured and embedded within
the stream when selected.
MGW Ace Encoder supports closed captions capture from SDI and Composite inputs
(CEA608/708 support). Captions are embedded within the Video Elementary Stream in
accordance to ANSI/SCTE128, ATSC A/72 standard [CC in HEVC User Data]
Closed captions can only be inserted when the encoding frame rate equals the video input framerate.
•
Encryption - AES Key -
AES key value available when "Encryption" box is selected. A
default key is provided.
•
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
–
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
–
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
standards. When unselected, all the KLV metadata frames are captured and transmitted
with the Video/Audio stream
•
DVB Mode
–
Select this check box to comply with DVB standard. At low bitrate (<1Mbps),
enabling DVB mode may result in an increased bitrate.
This parameter is then disabled in “ISR –
Low Bandwidth” profile.
•
RTSP
- Server Port
–
RTSP Server port (default is 554)
