User may configure the following previously fixed-value parameters:
Transport Stream ID - Configures the transport stream ID number used Program Specific Information (PSI) tables in the stream.
MPEG Program Number - Configures the MPEG Program used in all PSI tables for this stream.
PMT, Video, and Audio PIDs:
• Configures the Packet Identifier (PID) used to transmit all Program Map Tables in the stream.
• Configures the PID used to transmit Video and associated data.
• Configures the PID used to transmit audio and associated data.
All PIDs are displayed in Hex format. If you type a decimal format into the field, the GUI will automatically convert
your decimal format to a Hex value. PIDs are expressed in both decimal & hex formats to the right of the entry field.
Audio Language Descriptor - Configures the ISO 639 audio language. Use 3-character "Alpha-3" code for this setting.
Audio Language Descriptor 2 - Configures the ISO 639 audio language. Use 3-character "Alpha-3" code for this
setting.
Dual Audio Enable - Selections are either Enable or Disable the second audio channels. The SDI audio channels
used in the encoder are 0 & 1 for the primary audio and 2 & 3 for the secondary audio. The Analog audio inputs
do not support SAP.
P-Frames per GOP - Specifies total number of P frames in a Group-of-Pictures (GOP).
B-Frames between I/P- Specifies number of B frames between each I or P frame in a GOP.
Video GOP (Group of Pictures) Settings
Native Res. Advanced Settings: When streaming H.264 HD stream the default P-Frame per GOP is 14
and the default B-Frame between I/IP is 3, which gives you a default Total GOP Length of 60.
SD Only Advanced Settings: When streaming MPEG-SD stream the default P-Frame per GOP is 4 and
the default B-Frame between I/IP is 2, which gives you a default Total GOP Length of 15.
Service Info Type:
If Service Info Type is set to "DVB (NIT+SDT)" it also enables the fields:
• DVB Network Name - Specifies the "Network Name" in the DVB NIT table.
• DVB Service Name - Specifies the "Service Name" in the DVB SDT table.
• DVB Provider Name - Specifies the "Provider Name" in the DVB SDT table.
If Service Info Type is set to "ATSC (MGT+VCT)":
• VCT Short Name: 7-letter name for the channel.
Major Channel Number / Minor Channel Number: Specifies the two-part channel number in the VCT, typically
displayed in the format major-minor, for example "2-1".
DiffServ / DSCP -
Configures the value of the differentiated services code point (DSCP) field in the IPv4 header for
the video output stream. The format of this field is specified by IETF RFC2474, but actual values are specified by
several related RFCs. The encoder does not support explicit congestion notification (ECN) which makes use of the
lower 2 bits of this header field.
VLAN PCP / QoS - Configures the value of the Ethernet-frame level Priority Code Point in the IEEE802.1q VLAN
tag as specified by IEEE 802.1p. This setting only applies when the SFP video network has VLAN tagging enabled.
These values should be left at their default values unless the user has a specific reason to change them.
