| Real Time Transport Stream
Demultiplexer(Tuner) for real time forwarding of selected programs
(PIDs) from Complex Multiprogram Transport Streams. Ideal for pulling
out only selected programs from complex satellite feeds.

Professional
Grade Linux Based Transport Stream Multiplexer / Remultiplexer for
Combining 2-4 Single or Multiprogram Transport Streams. Supports
4 DVB ASI inputs and either ASI or SMPTE 310M output. Also serves
as a static PSIP Table Inserter when configured with a SMPTE 310M
output or SI table inserter when configured with ASI output. Can
be configured to reconfigure SI or PSIP tables in real time. Now
able to mux one stored stream on HD in addition to 4 live streams
resulting in 5 streams being muxed.

Professional Grade Linux Based
Transport Stream Multiplexer / Remultiplexer for Combining 2-8 Single
or Multiprogram Transport Streams. Supports 8 DVB ASI inputs and
either ASI or SMPTE 310M output. Also serves as a static PSIP Table
Inserter when configured with a SMPTE 310M output or SI table inserter
when configured with ASI output. Can be configured to reconfigure
SI or PSIP tables in real time. Now able to mux one stored stream
on HD in addition to 5-8 live streams resulting in 9 streams being
muxed.

|
|
| Table |
Function |
| MGT(Master Guide Table) |
Describes the PSIP tables present |
| TVCT(Terrestrial Virtual Channel Table) |
Lists the virtual channels being sent |
| STT(System Time Table) |
Conveys the current UTC time |
| EIT(Event Information Table) |
Provides basic "EPG" information, including start
time, title, and length, The EIT also includes:
- AC-3 Audio Descriptor
- Caption service descriptor
- content ID descriptor
- Redistribution control descriptor |
| RRT(Rating Region Table) |
Conveys information on the content advisory rating system
in use. (Not required in some areas) |
| ETT(Extended Text Table) |
Provides extended description of PSIP events, i.e. storyline,
performers, etc. |
| Other PSIP Tables of Interest |
| DCCT(Directed Channel Change Table) |
Instructs receivers to change from a given channel to another
over a given time period. This change may be unconditional or
based on geographic, demographic, or other selection criteria. |
| DCCSCT (Directed Channel Change Selection
Code Table )(Optional) |
Provides updates to genre, state, and country codes. |
