[QUOTE="FenMP, post: 608562, member: 103768"] Hi sdf, first of all thank you for your reply. (As you know people read the posts, only some want to reply, but only a few finally does it) The reason why I wanted hardware encoding was for recording (but I see now that I might be wrong about it!!!). This is the way I see it: [LIST=1] [*]You receive the DVB-T signal in "whatever format" and you want to save it to the HDD (record the tv). [*]You want to record it either as MPEG4 (DivX or Xvid) or H264, but the CPU needs too much processing power to do it. [*]But if you have a hardware encoder that supports those formats then you might free some CPU cycles. [/LIST] Examples of what I think. [COLOR="Red"]ATTENTION!!![/COLOR] THIS NUMBERS ARE [U][B][FONT="Arial Black"]NOT REAL FIGURES [/FONT][/B][/U]they are just rough numbers [U]of how [B]I think[/B] the system works[/U]. (I dont want to create any misunderstandings). So please correct me if Im wrong and point me in the right direction towards what Im looking for, Thanks :) [CODE] Harware Recording RECORDING DVB-T RECORDING HDTV Encoder Format Usage Usage TV Card CPU TV Card CPU NO MPEG-4 40% 40% 55% 75% NO H.264 40% 70% 55% 110% MPEG-4 MPEG-4 80% 5% 100% 12% MPEG-4 H.264 40% 70% 55% 110% H.264 MPEG-4 40% 40% 55% 75% H.264 H.264 80% 5% 100% 15% Both MPEG-4 60% 3% 80% 8% Both H.264 70% 5% 99% 10%[/CODE] As you can see in the table before, the more quality the signal has the more resources it requires.
