DVB Remultiplexer 1-to-1

Description

The MVD DVB remultiplexer 1-to-1 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 or pass through of the current NIT.
• Regeneration of PSI/SI tables PAT and SDT.
• 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 / 1 SPI output
• Adapt an MPEG TS mux rate into another by filtering complete services
• Management of PSI/SI tables (automatic tables generator) according to ETS300468 and ISO 13818-1
• Configurable via a RS232 link
• Service filtering and insertion of custom NIT
• Full PCR re-stamping
• Master/Slave control of output mux flow
• Statistical service bandwidth estimation
• Maximize output payload bandwidth thanks to smoothing FIFO
• Smoothing FIFO can be implemented as block RAM or external Synchronous SRAM memory
• Configurable size of the smoothing FIFO
