MPEG
processes and preserves generic MPEG control tables, but discards MPEG
application-specific SDTs.
DVB
processes and preserves Digital Video Broadcasting (DVB) control tables. This
setting forwards the SDT on PID
17
through the demultiplexer.
None
discards all incoming SI/PSI tables. Use this SI mode when a streamer or data
carousel is providing the PAT and PMT
.
Transport Stream ID
This parameter sets the transport stream ID transmitted in the system information tables.
Base PID
Base PID
applies to Program 1 on this interface. When the
PID Map
operates in
Auto
, this
base value helps compute the first PID for a channel's program. Other PID mapping
conventions ignore this base PID value.
Carousel Rate
This parameter sets the data carousel bitrate for the interface (from
0
to
16,000,000
bps). If
the interface's carousel has streaming enabled, this bitrate governs the maximum transport
stream bandwidth that will be used by carousel data. The quantity, and rate of other
carousels on this interface may limit the maximum rate per carousel.
Carousel Stream
Data carousel streaming is enabled or disabled by this setting.
Enable
turns on carousel
handling. If a valid carousel file is present, and its activation time has arrived, the file's data
will be multiplexed into the interface's transport stream.
Disable
turns off carousel
streaming. Any existing carousel files are ignored, and the interface does not check for new
carousel files, nor is carousel data multiplexed into the transport stream.
PID Map
Use this control to specify whether PIDs in programs on this interface should be mapped
automatically or manually.
In the
Auto
setting, the module uses its own
Base PID
and the VC's program number to
determine a
Base PID
value for the program. It then assigns a group of 16 PIDs to the
program as described in
The
Base PID
is assigned to program number
1
.
In
Manual
mode, each VC specifies its own PID values, using the configuration values in
the VC's program group. MPEG defines a packet identifier as a 13-bit number, reserving 0
through 15 and 8191 (0x1FFF). The ATSC standard further reserves PIDs below 48.
Moreover, the ATSC program guide (PSIP) tables conventionally use PIDs at 7680 (0x1E00)
and above. The automatically assigned values avoid these ranges, and uses values from 32
to 7167 (0x1BFF).
Note:
In
Manual
mode, all PIDs for the interface must be unique. If a VC tries to use a PID
that has already been assigned on the same interface, the VC will declare a
Transmit
Channel Configuration Error
fault.
