DVB-T usage on an 'average PC'

, posted: 1-Apr-2008 19:16

Just if anyone is interested, below is a screen of the CPU usage on what i'd describe on a fairly 'average' PC (it's more a 'bitser' that I use as a media PC)

See the difference between the HD TV3 feed (nearly going 100% CPU) and the SD C4 feed. TV3 looks by no means perfect, but it's not overly stuttery.


CPU usage


PC Spec:
Core 2 Duo E6300
Hauppauge HVR900
Radeon 9600XT 256MB


Software:
MediaPortal SVN Build 2008-03-26
Windows XP SP2
Using FFDShow video filter (build rev1920_20080328_sse)

That is why a video card with H.264 acceleration is essential for DVB-T in New Zealand. Using PowerDVD Ultra's H.264 codec with hardware acceleration with a supported video card and that will drop down to around 5% - 10% CPU usage on all channels.

sbiddle - fair point and I totally agree.  Was merely pointing out that it is possible without a brand new video card etc.  I probably will upgrade either that or my main PC (that has a 7300GS) in due course, but right now I have other financial priorities
