HOWTO: Leverage PVR350 Hardware MPEG encoding?

Matio · 2005-10-17, 10:53

Hi all,

this may be a dump question, so please bear with a NEWBIE. I tried to find the answer searching in the forum, but did not succeed.

Within my HTPC I have two TV cards: a PVR 350 and a Cinergy DVB-T 1200.

Now, the PVR350 has hardware MPEG encoding built-in. I'd assume that this implies that - due to the fact the decoding is done by hardware - the MPEG encoding does not impact the CPU, right ?

So, how can I benefit from this? Is it possible to re-direct the MPEG encoding for the DVB-T card to be done by the PVR350?

Can it be as simply as setting the HAUPPAUGE PVR350 MPEG Codec as the default for watching TV?

Any help would be appreciated...

Regards,

Matio

The PVR350 has a hardware encoder so it does lower the cpu usage a lot. It does not have any part in the decoding process and is left to the codec. DVB-T cards do not need mpeg encoding because the digital stream comes already in mpeg2 format.
