Configuration Process
‘HybridPorts’ Files
The ‘HybridPorts’ files serves 3 purposes:
• It identifies the ports that form the core and their connections.
There are IN and OUT commands for the core ports.
• It identifies the ports that have certain attributes that affect DHP.
These attributes are
• Input ports that have the “force embedder” attribute (EO command).
• Output ports for which DHP emits video only (VO command).
• Input and output ports that belong to tielines (TL command).
The commands that specify these attributes (EO, VO, and TL) must appear in the HybridPorts
file after the core commands.
• It specified the maximum number of embedded audio channels in NV8500 router inputs.
Use the CHANNELS command. (The CHANNELS command can appear anywhere in the file.)
You can refer to the sample initialization files (located in the C:\nvision of the NV9000 system
controller in which DHP resides) for further information.
Core Ports
There are two kinds of commands that you can (and must) write in the file.
IN ‹port-A› ‹type› ‹port-B›
OUT ‹port-B› ‹type› ‹port-A›
These commands must be paired. Port-A must be identical in both commands of the pair and
port-B must be identical in both commands of the pair. If there is a mismatch, DHP will return an
error report in its log file:
C:\nvision\envy\userlocal\logs\HybridSVC.log
If the error is severe, the DHP service will not run.
The ports are video port numbers in the range supported by the router. Please refer to the port
enumeration drawings, RF0272 through RF0276.
The recognized values for ‹type› are
1 — re-embedder
2 — disembedder
