High Definition playback , PC specs please !

Post by s8n »

hi RB members , i am looking to get a new PC built in the future and one thing i want it to do is play Blu-ray Disc's without stuttering. Also i am going to get a HD Video Camera aswell that can hit MXP 24Mbps recording mode.


i have some questions though.........

when it says 24Mbps is that 24 Mega Bytes a second or Megabits a second ?

i have pulled from another Forum the below specs for PC's running HD content

what are users on this Forum using to playback Blu-ray Disc's on a PC and HD downloaded media for example Youtube/Vimeo and Torrents of stuff that are in HD format ?


chat soon

Mbps is megabits per second. As there are 8 bits to a byte, that means 3 MB/sec. When abbreviating things, a lower-case 'b' is "bit" and a capital is "byte".

For playback of Blu-ray, the more practical thing to look for is a video card that accelerates h.264 playback (the codec that Blu-ray uses). That'd be...well, most current models, though some may support more additional filtering/features than others.
If you intend to do 3D playback, you may need to step up to the most current models - offhand the Radeon 6750 and 6770 only actually added 3D Blu-ray support over their predecessors via a BIOS tweak.

This article may be of interest to you - though it only really deals with low end cards. Frankly though, most anything you get that's worthwhile for gaming will be as good or better for video.

Secondly, use software that supports that hardware acceleration.

If you're looking at pure CPU power, you don't have much to worry about unless you're shopping for a netbook or similar. Occasionally you might still run into a poorly encoded HD video file that gives problems. I've had few issues with the Athlon X2 4850e in my HTPC, which was a sub-$100 CPU when I bought it a little over three years ago. I don't use it for actual Blu-ray discs...but I've played Blu-ray rips on it and other downloaded HD video (fansubbed anime and such).

The most important thing is a graphics card AND a display that supports HDCP. Without either of those the only way you're going to be able to play blurays is if you rip them and transcode them, which takes time and space on your hard drive. Make sure you get a retail Bluray drive that comes with software, otherwise you may have a bluray drive but you'll have to pay money for some software to play the discs on the fly (otherwise you're going to have to rip them and transcode them...).

Most modern PCs will be able to play the actual content without a hitch, well as long as you aren't picking the bargain basement components out like a single core atom or something like that.
