Manual Routing Mapping Restrictions
In the bulleted list below, the SEM identifies a GigE input transport stream based on the physical GigE interface and receive UDP Port. The following restrictions apply to the routing of programs and transport streams:
• A GigE input program from a specific input transport stream can only be mapped to one output. This means that a program received on a UDP port on a specific GigE interface cannot be mapped to multiple outputs.
• A GigE input transport stream can only be passed through to one output.
This means that an input transport stream received on a UDP port on a specific GigE interface cannot be passed through to multiple outputs.
• If a GigE input stream is being passed through to an output stream, no programs on that input can be mapped to an output.
• If a GigE input program is being mapped as a wild card (input program number 0), no other programs from that input stream can be mapped to the same output stream.
• If a program is pre-encrypted (and the pre-encrypted check box is selected), the input ECM PID and input PMT PID must be on different PIDs.

PAT TS ID The output transport stream ID to use for the output PAT in this output transport stream when in manual routing mode. This parameter takes immediate effect.
Changing this setting will cause all programs already mapped to be deleted and re-added. This will result in a momentary glitch in the video stream.
*GigE Tx Multicast Interface Identifies the specific GigE interface (1 or 2) used as the output. When a GigE output stream’s destination IP address is a Multicast IP address, this setting defines the physical GigE interface that will be used. Singlecast and broadcast GigE outputs use the network stack’s routing table (based on destination IP address) and the user defined static routing table to determine which physical GigE interface to use.
Output IP Address For GigE 1–3, it specifies the output IP address on which to place data when in manual routing mode.
It is used with IP based output interfaces. The Output IP address must be a valid class A, B, C, or D address. Additionally, the output IP address and UDP port for each GigE output must be unique for each output stream. The same output IP address can be used for multiple GigE outputs, but each output stream must then have a unique UDP port.
This parameter takes immediate effect.

SEM UDP Mapping Example
In this mode, the sixteen-bit UDP port number is generated using the output transport stream, UDP port offset value, and the output program number. The UDP port number will always be an even number.
The UDP port bit fields are:
• UDP port bits 15 through 13 are the UDP port offset value.
• UDP port bits 12 through 9 are the output transport streams 1 through 16 (transport stream 1 is represented by 0x0 and transport stream 16 is represented by 0xF).
• UDP port bits 8 through 1 are the output program numbers 1 through 256 (program number 1 is represented by 0x0 and program number 256 is represented by 0xFF).
• UDP port bit 0 is always zero.
In general, the UDP port calculation is:
UDP Port = Offset + 512 * (Output Transport Stream – 1) + 2 * (Program Number – 1)
Typical UDP mapping example with port offset value of 0 is provided in Table 4-39:
