[linux-dvb] Origin of datarate limitation?

["Sven Karlsson" <svenka@it.kth.se>]

Hi All,

I've read at numerous places that there is a datarate limitation on the
parts of the TS that can be read from the AV711x via the PCI bus. I also
understand that the Nova does not have that limitation and that the Nova
does not have any hardware MPEG playback capabilities although it is based
on the AV711x.

Could someone (possibly yet again ;-)) clarify the origins of the data rate
limitation on MPEG capable cards? It appears to me that this could be a
firmware issue. Is that so? Are there any efforts focusing on patching the
firmware or otherwise remove the datarate limitation at the possible expense
of the MPEG capabilities?

I, for one, would gladly skip all MPEG capabilities of the board if I
instead could process and possibly record several channels at once. My DVB-C
card is sitting in my firewall/network server and I intend to send the MPEG
stream over my home lan to my other boxes which all of them are powerful
enough to decode MPEG-II streams in realtime.

Best regards
 Sven
