The MVD N-SPTS to 1-MPTS
Multiplexer IP core performs ATSC or DVB standard mixing of up
to 32 incoming SPTS stream.
The input supports 188 to 255 byte frames with a maximum frequency of
13.5MHz for 108Mbits/sec.
The output is clocked from an MVD_DVBx core (in slave mode) or by
itself (in master mode) with a maximum frequency of 14 MHz for 112 Mbits/sec.
The rate conversion is made through a smoothing FIFO memory (1 BRAM: up
to 10 frames).
A 32-bit CPU interface is available for core control. By default the
core can start up without CPU initialization; in this case, no modification is done into the stream
(no conflict is managed, user must take care to incoming stream
- Drop-in module for
7-Series FPGAs in charge of mixing DVB/ATSCtables and payload for SPTS
- Incoming stream analysis,
captures ATSC/PSIP or DVB/PSI/SI sections, PMT sections and extracts
needed stream parameters
- A processor interface
allows to control the CORE configuration and to get basics information
such as incoming bitrate, outcoming bitrate, useful payload bitrate, current FIFO state, for the general purpose part. In addition, it
allows downloading PSIP/PSI/PMT tables, solving serviceID and PID
conflict between inputs
- The N-SPTS to 1-MPTS
Multiplexer manages the generation of output tables: new PAT, VCT, SDT,
updated MGT and PMTs (when required)
