SAP for Destination 1 and/or 2
Category An encoder can have a SAP Category string. This string consists of
one or more keywords separated by spaces. Each category keyword
represents a tag associated with the Encoder's video stream.
Decoders can be configured to display in their Program and Guides
only video streams tagged by specific category keywords or those
containing no keyword. The string(s), used by the Decoder, is set on
the Decoder/Network screen. Note: Characters are ASCII and are
case sensitive. The total of all keywords in the string is 36 characters
including spaces.
You can also use this field to filter the live streams shown in the
ETV Portal Server by source and client IP address by using the
following string:
IPMask=xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx
represents a bit mask. (This string is simply another keyword you
can use in addition to those described above.) The Portal Server will
parse the bitmask and send the live stream only to clients with a
masked IP address that matches the masked IP address of the
source VBrick. For example, a stream with a category
IPMask=255.255.0.0 from a VBrick with an address of 172.22.6.67
will be available to a client with an IP address
172.22.3.4 but not to
a client with an IP Address
172.16.3.4. There is no admin interface
to this feature on the Portal Server; you can use this filtering in
addition to the standard authorization features provided by the
Portal Server.

Name field for a description of replace characters (\h, \b or \f).

transmissions of SAPs (1 – 9999). If SAP Timing is variable, the actual
retransmit time as per RFC 2974 is reported back. Please refer to
Configuration: System > General.
Time to Live The number of hops (between routers) for which an IP packet is valid
on the network.
Type of Service The TOS (Type of Service) can be configured in the IP header to
establish SAP packet priority in the network.
SAP IP Address The receive IP address used to populate the Program Guide. This is
typically set to the Announce Program Guide SAP of the encoder.
