MGW Ace Encoder HEVC Encoding and Streaming Appliance
User Manual, Version 2.1 40
• QP Range Min - Minimum quantization (compression) value (range is 1-51, default is
16). When a minimum value is set, the encoder will not use a lower value than specified.
This setting is mainly relevant for content with minimal movement where bit rate
allocation can be reduced.
• QP Range Max - Maximum quantization (compression) value (range is 1-51, default is
44). When a maximum value is set, the encoder will not use a higher value than specified.
This setting is specifically relevant in motion-intensive scenes where higher bit rate
allocation is needed.
• Initial Delay (ms) - The delay for incoming PTS/DTS relative to PCR (range is 50-500,
default is 96). This setting enables the control of buffering within the receiver / decoder.
• Maximum Delay - Maximum duration threshold before Access Units (AU‘s) are
multiplexed together. This setting minimizes high bitrate variations (range is 1-1000,
default is 192).
• 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 1 PID – A unique identifier of the audio service within the transport stream. Up to
two Audio services can be available per a transport stream. Default: 1242.
• Audio 2 PID – A unique identifier of the audio service within the transport stream. Up to
two Audio services can be available per a transport stream. Default: 1243.
• KLV 1 PID – A unique identifier of the KLV (Key Length Value) metadata service within
the transport stream. Default: 497.
• KLV 2 PID – A unique identifier of the KLV (Key Length Value) metadata service within
the transport stream. Default: 498.
• DVB Mode – Select this check box to comply with DVB standard. At a low bitrate
(<1Mbps), enabling DVB mode may result in an increased bitrate.
• RTSP - Server Port – RTSP Server port (default is 554)
• Encryption - AES Key - AES key value available when "Encryption" box is selected. A
default key fills the text box.
