Description
The MVD DVB remultiplexer 1-to-2 core is
a drop-in module for reducing the MPEG TS
rate by filtering services selected by an
external host controller.
- The remultiplexer is managed by
an external host via the RS232
link. The host is in charge to
read the statistical data and to
select the services to filter.
- Generation of a new NIT follows 3
possibilities:
- pass through of the
current NIT
- new one provided by the
host
- autogeneration of a
simple one with channel
numbering
- Regeneration of PSI/SI tables PAT
and SDT independtly of the
output.
- Large smoothing FIFO to optimize
the bandwidth of the output rate.

Features
- Drop-in module for
Virtex-5™, Virtex-4™
and Spartan™-3A_DSP FPGAs
- 1 SPI input / 2 SPI outputs
- Converts an MPEG TS mux rate into
2 independent MPEG TS mux rates

(automatic tables generator)
according to ETS300 468 and ISO
13818-1
- Configurable via a RS232 link
- Service filtering and insertion
- Full PCR re-stamping

estimation
- Optimize output mux rate thanks
to smoothing FIFO
- Smoothing FIFO is implemented as
block RAM (no need of external
component)
- Configurable size of the
smoothing FIFO
