Some drives can read and write burn information onto a blank disc, while other drives can only read information. There are four different types of drives and discs that use different technologies:. A Blu-ray disc is a form of optical disc. Because they can hold so much more information, Blu-ray discs can provide high-definition audio and video for output on HD TVs and surround sound systems, while an ordinary DVD cannot.
Since Blu-ray discs are formatted in a way designed to be read by a blue-violet laser, which has a shorter wavelength than the conventional red lasers used by standard DVD players, Blu-ray discs cannot be read by an ordinary DVD player.
Blu-ray is an evolving technology. Sony licenses the technology to some other manufacturers, but Sony is the corporation that develops the technology and its standards. They are two separate technologies. The two disc formats are not compatible with one another. You will have to review the user's guides and specifications for both your computer and and for your television. The difference is mostly in the number of components and the types of cables you may need. When connecting to an external monitor, you may not care if your high-definition content can be displayed on it.
The external monitor may not even be capable of displaying such content. Additionally, when you connect your computer to a monitor, you may not care about the sound quality. If you are connecting to an HDTV, you might also wish to connect your computer to a surround sound system for a complete home theater experience.
You can do this in several ways. All of this depends on your equipment and what you have available. Likewise, if you have that same Xbox hooked up to a non-HDTV, the television will not be able to output the information in high definition. You will need the correct drivers to run your Blu-ray optical drive, and you will need audio and video codecs to be able to read the information on a Blu-ray disc. A codec is a method of encoding and compressing information, and then decoding and decompressing it for use.
This and other software should have arrived already installed on your notebook if it came with a Blu-ray drive, and updates for your system are always available at the HP Drivers and Downloads website. You should be aware that these types of discs are still extremely expensive, as demand has not yet driven down their cost.
The older your Blu-ray player is, the more likely it is that it won't be able to handle making legal copies of disc content to another device. The earliest Blu-ray players sold probably do not have a fully developed version of this system on them, and thus probably cannot make legal copies of content.
From your first mplayer output, you must find the codec used for the Blu-ray. It will be at the end of the line "Selected video codec". When this happens, aacskeys AUR will return this message:. This is part of the AACS protection scheme: editors are able to revoke old software player host keys that have leaked on the Internet and distribute the lists on newer commercial disc releases.
This is irreversible and cannot be fixed even after reflashing the drive. The only two ways to correct this would be:. Install aacskeys AUR. Try makemkv AUR , it may give you clearer error messages if nothing else.
If you have a supported drive, you may also look at flashing it with a custom firmware which allows the entire disc to be read without verification. This is referred to as enabling "LibreDrive" mode.
Options are explained a bit in discussion of the GUI wrapper which may help to determine when options like enc are required. Like any other firmware flash, be very careful - there is the possibility of bricking your device. Once flashed the change is persistent and the new firmware should allow media players like VLC to read the disc directly without makemkv's involvement.
For DVD, the libdvdcss package supplies the needed decryption libs. Users can employ to backup a commercial Blu-ray movie under Fair Use guidelines:. Related articles Optical disc drive. Note: The download provided is a. You may have to rename the file to end with. The content code can implement a fix for the distorted video so that licensed playback is still problem free. In this scheme, BD-J code on the disc actively looks for signs of protection being in place during playback.
When the BD-J code finds that the protection features are missing say, due to playing an unprotected copy, or when ripping tools are active in the background , playback is immediately stopped along with an on-screen message.
In addition to DRMs aimed at directly protecting content by encryption, the Blu-ray developers also considered some watermarking schemes. In the next section, we will be talking in detail about Cinavia, the audio watermarking scheme from Verance. If you are interested in learning more about content protection in Blu-rays, I strongly suggest perusing Chapter 4 of Blu-ray Disc Demystified.
For the consumer, this entails: 1. Protected storage Conditional access is applicable to cases where media travels over insecure channels such as satellite or cable.
