There
is
no
“Table

functionality
with
ASI
Remux.
Ingress

are
copied
to

If
the
user
attempts
to
set
a
TMR
and
an
ASI
Input
Reserve
that
does
not
allow
enough
bandwidth
for
the
locally
encoded
service
(dependent
on
resolution
and
encoding
modules)
the
TMR
will
be
auto
calculated
to
allow
for
ASI
Reserve
and
minimum
value
allowed
for
locally
encoded
service

TMR

**TMR
and
locally

take
priority
over

Therefore
if

is
set
to
a
rate
that
does
not
allow

for

then
the

PID
Mapping
Terminology:
Transport
Stream
-
A
stream
of
188-byte
transport
packets
that
contains
audio,
video
and
data
belonging
to
one
(SPTS)
or
several
(MPTS)
programs.
PID
-
Packet
Identifier.
This
unique
integer
value
identifies
elements
in
the
transport
stream
such
as
tables,
data,
or
the
audio
for
a
specific
program
PAT
-
Program
Association
Table.
This
MPEG-2
table
lists
all
the
programs
contained
in
the
transport
stream
and
shows
the
PID
value
for
the
PMT
associated
with
each
program.
The
PAT
is
always
found
on
PID
0x0000.
PMT
-
Program
Map
Table.
This
MPEG-2
table
specifies
PID
values
for
components
of
programs.
The
Adtec
EN-3X
and
EN-100
encoders
have
an
ASI
input
available
for
the
ASI
remux
feature.
Further
information
can
be
read
about
ASI
Remux
in
the
ASI
Remux
article.
In
some
cases,
users
may
want
to
add
custom
PID’s
from
third
party
generators,
such
as
a
DVB
Subtitles,
into
the
main
video
programming.
With
a
custom
application,
the
standard
ASI
remux
feature
would
not
work
without
additional
configuration.
To
keep
the
system
open-ended
and
to
allow
any
type
of
special
passthrough
application,
we
have
allowed
the
user
to
configure
any
type
of
PID
passthrough.
Some
DVB
Subtitle
Generators
do
not
generate
MPEG
Transport
Stream
Tables
(PAT,
PMT).
In
order
to
associate
DVB
Subtitle
PIDs
with
the
desired
program
on
the
EN
output,
the
encoder
PMT
must
be
modified.
A
wiring
diagram
and
sample
PMT
view
can
be
seen
in
the
drawing
below.
