Entertainment Industry Looks To Force Massive Copyright Changes Int'l (who WRITE the Treaties?)

I suspect it is the stuff they are putting on the dvds to stop them from being ripped.

Handbrake will take care of most DVDs.

More due to the way the encoding/decoding of the actual picture stream works in a DVD format vs. BluRay, the wavelength of the laser, etc.

Got it. Thanks.

Thanks. I hate Hollywood except when they put out good stuff. It’s completely insane how they put out all this garbage. I’m becoming a foreign film freak now. Bollywood is looking better and better. Have you ever seen “My Faraway/Bollywood Bride?”

I somehow doubt that Dick Wagner or Peter Tchaikovsky give a rat’s *** over how much of their music I download...

***but the public is told that the treaty negotiations are matters of national security and cannot be revealed.***

LOL

Is there anything that isn’t a matter of national security these days?

rat’s ***

I hold the rights to that phrase . Cease and desist or I will be forced to take steps .

Art was better before copyright.

That's because then the standard for judging art was beauty. Now it's just uniqueness.

This is all approximate, and most-common:

DVD:
Data Capacity: 8 GB (dual-layer)
Video encoding: MPEG-2
Max video quality: 9.8 Mb/s (most commonly 2-3 Mb/s with bursts to 6 Mb/s)
Max video size: 720 × 480 at 60 Hz (interlaced, IIRC)
Audio encoding: AC3 or DTS
Max audio quality: 24-bits/96 kHz lossy compressed standard, somewhat higher optional
Maximum video length: Less than two hours at maximum quality and resolution.

Blu-ray
Data Capacity: 50 GB (dual-layer)
Video encoding: MPEG-4 AVC
Max video quality: 40 Mb/s (commonly 20-30 Mb/s with bursts to 40 Mb/s)
Max video size: 1920×1080 at 24 Hz progressive (60 Hz interlaced)
Audio encoding: Many, including uncompressed HD audio at 8 Mb/s
Max audio quality: 24-bits/96 kHz lossless (no audio degradation due to compression) standard, up to 192 kHz optional.
Maximum video length: Over two hours at maximum quality and resolution.

Remember, the video encoding in Blu-ray is much more efficient, so you get better quality per-bit too, in addition to having a higher overall bitrate.

Max video size: 1920×1080 at 24 Hz progressive (60 Hz interlaced)

Good data, but 24 Hz frame rate interlaced at 60 Hz??? How does that work?

Lol, back to 24 fps, just like the good old, OLD days. :-)

Do you know how they dealt with the flicker at that rate back then? They flashed the image twice with a rotating shutter to preclude the persistence on the retina. The guy who thought of that was a genius.

Not True, there is a format called "3x DVD" which was a subset of the HD-DVD standard that could support approximately 100 minutes of 1080P encoded with the VC1 codec.

Physically the "3x DVD" is a on ordinary DVD, I believe the Blu-ray equivalent is called BD9.

Sadly these HD formats which were to find there way into dvd recorders were much too practical and consumer friendly to be allowed to live by the entertainment industry. Can't let Jack and Diane permanently record 24 in HD now can we...

Good data, but 24 Hz frame rate interlaced at 60 Hz??? How does that work?

The source can be 60 Hz interlaced or 24 Hz progressive.

24fps is perfect because that's what movies are filmed at. From source to Blu-ray without any messing about with telecine and odd frame duplication. A 120 Hz TV can do 24, 30 and 60 fps all without having to put odd numbers of frames. Quite a good picture when you go that route.

Yes, I just love how "national security" gives them more power to surveil you, yet gives you LESS to do so to them.
