Media Identification Code
The Media Identification Code (MID) is used on DVD-R, DVD+R and DVD-RAM discs to identify the manufacturer and to assist the DVD burner to select the best write strategy for the inserted media. The technology is inherited from the ATIP code used on CD-R discs. If the DVD burner recognizes the discs it means that the disc has been tested by the drive manufacturer to achieve the best possible burn using an optimal write strategy. The strategy is stored in the firmware. Writing to a disc with no MID code or a code that is not recognized can result in inaccurate recording and data read-back problems. Displaying the MID The following programs can be used to display the contents of the MID With Windows * instalDVDInfoProby Nic Wilson (full 14-day trial available without any adverts) * instalDVDIdentifierby Kris Schoofs (freeware) With Linux Ubuntu and other Linux systems have dvd+rw-tools The DVD (common abbreviation for Digital Video Disc or Digital Versatile Disc) is ...

DVD-R
DVD recordable and DVD rewritable are optical disc recording technologies. Both terms describe DVD optical discs that can be written to by a DVD recorder, whereas only 'rewritable' discs are able to erase and rewrite data. Data is written ('burned') to the disc by a laser, rather than the data being 'pressed' onto the disc during manufacture, like a DVD-ROM. Pressing is used in mass production, primarily for the distribution of home video. Like CD-Rs, DVD recordable uses dye to store the data. During the burning of a single bit, the laser's intensity affects the reflective properties of the burned dye. By varying the laser intensity quickly, high density data is written in precise tracks. Since written tracks are made of darkened dye, the data side of a recordable DVD has a distinct color. Burned DVDs have a higher failure-to-read rate than pressed DVDs, due to differences in the reflective properties of dye compared to the aluminum substrate of pressed discs. Comparing recordab ...

DVD+R
The DVD (common abbreviation for Digital Video Disc or Digital Versatile Disc) is a digital optical disc data storage format. It was invented and developed in 1995 and first released on November 1, 1996, in Japan. The medium can store any kind of digital data and has been widely used for video programs (watched using DVD players) or formerly for storing software and other computer files as well. DVDs offer significantly higher storage capacity than compact discs (CD) while having the same dimensions. A standard DVD can store up to 4.7 GB of storage, while variants can store up to a maximum of 17.08 GB. Prerecorded DVDs are mass-produced using molding machines that physically stamp data onto the DVD. Such discs are a form of DVD-ROM because data can only be read and not written or erased. Blank recordable DVD discs ( DVD-R and DVD+R) can be recorded once using a DVD recorder and then function as a DVD-ROM. Rewritable DVDs (DVD-RW, DVD+RW, and DVD-RAM) can be recorded and e ...

DVD-RAM
DVD-RAM (DVD Random Access Memory) is a DVD-based disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998. In May 2019, Panasonic, the only remaining manufacturer of DVD-RAM discs, announced that it would end production of DVD-RAM media by the end of that month, citing shrinking demand as the primary motivation. Panasonic made its discs under its own brand name and also under the Verbatim brand. Cartridge types Format DVD-RAM works by means of phase change technology which was chosen instead of magneto-optical technology (an already existing rewritable solution at the time) because it doesn't require a magnetic head and therefore it represented reduced complexity and costs. Phase change technology uses laser light to heat the surface of a phase changing alloy and allows it to go from a crystalline to a ...

CD-R
CD-R (Compact disc-recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs. History Originally named CD Write-Once (WO), the CD-R specification was first published in 1988 by Philips and Sony in the Orange Book, which consists of several parts that provide details of the CD-WO, CD-MO (Magneto-Optic), and later CD-RW (ReWritable). The latest editions have abandoned the use of the term "CD-WO" in favor of "CD-R", while "CD-MO" was rarely used. Written CD-Rs and CD-RWs are, in the aspect of low-level encoding and data format, fully compatible with the audio CD (''Red Book'' CD-DA) and data CD (''Yellow Book'' CD-ROM) standards. The Yellow Book standard for CD-ROM only specifies a high-level data format and refers to the Red Book for all physical format and low-level code de ...

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dvd+rw-tools
dvd+rw-tools (also known as growisofs, its main part) is a collection of open-source DVD and Blu-ray Disc tools for Linux, OpenBSD, NetBSD, FreeBSD, Solaris, HP-UX, IRIX, Windows and OS X. dvd+rw-tools does not operate CD media. The package itself requires another program which is used to create ISO 9660 images on the fly. This is provided by mkisofs (from the cdrtools package) or genisoimage (from the cdrkit package) or a symbolic link xorrisofs to xorriso (from the libisoburn or GNU xorriso package). Released under the GNU General Public License, dvd+rw-tools is free software.

Content ID
Content ID is a digital fingerprinting system developed by Google which is used to easily identify and manage copyrighted content on YouTube. Videos uploaded to YouTube are compared against audio and video files registered with Content ID by content owners, looking for any matches. Content owners have the choice to have matching content blocked or to monetize it. The system began to be implemented around 2007. By 2016, it had cost $60 million to develop and led to around $2 billion in payments to copyright holders. By 2018, Google had invested at least $100 million into the system. Overview Content ID creates an ID File for copyrighted audio and video material, and stores it in a database. When a video is uploaded, it is checked against the database, and flagged as a copyright violation if a match is found.More about Content ID YouT ...
