Why is the 7.1 optional but but not standard on BD? - Blu-ray Forum

Rivera213 · 01-15-2007, 11:36 PM

As the thread says, why is it only optional & not standard to have Dolby 7.1 sound on the Blu-Ray disc, but IS standard on the HD-DVD.

The Blu-Ray has more sound capacity i've been told so why isn't it at least stndard?

To me, the sound is the eason why i am a blu-ray supporter (cos it has more potential than HD-DVD).

Can anyone help me out?

7.1 is optional on both formats, at the request of the studio's I would imagine.

I thought it was standard on HD-DVD.

My bad.

What if you were to record onto a 50GB Bd-R, would that be 7.1 capable cos the player i've seen can play Full HD 1920x1080 & 7.1 audio & as a guitar player, later down the line i wanna record my playing & sound is more important than video as long as it's HD, but i was told BD kills the HD-DVD potentially in the sound area?

To make your own 7.1 recording you would need a Blu-ray burner for the PC with studio quality hardware and software.
The home Blu-ray recorders coming late this year will be able to record 5.1 from network ATSC broadcasts.

Or in his case, DVB.

The DVB consortium announced future support for the MPEG-4 codec in broadcasting for Digital TV in Europe as well as in countries using the DVB Digital TV broadcast solution

This brings up the possibility of 1080p broadcasting for Europe starting 2009 onwards.

This means that you would be able to record MPEG-4 broadcasts and burn those recorded content to any Blu-ray media.

Sorry lads, i'm completely lost.

I'm a complete NOOB i'm afraid.

So i can't record from the camera (professional quality which can shoot full HD) onto a BD-R 50GB with 7.1 Sound?
