DVB Remultiplexer 1-to-2

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
• Management of PSI/SI tables (automatic tables generator) according to ETS300 468 and ISO 13818-1
• Configurable via a RS232 link
• Service filtering and insertion
• Full PCR re-stamping
• External or internal output mux rate
• Statistical service in bandwidth 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
• Full synthesizable RTL design (not delivered) for easy customization
• Netlist version available for ISE 10 and later
