Digital Negative (DNG) is a patented, open, lossless raw image format developed by Adobe and used for digital photography.Adobe's license allows use without cost on the condition that the licensee prominently displays text saying it is licensed from Adobe in source and documentation, and that the license may be revoked if the licensee brings any patent action against Adobe or …

Some common multimedia file formats are not completely distinct container formats. Some are containers for specific audio and video coding formats, such as WebM, a subset of Matroska.Some are combinations of common container formats and audio and video coding profiles, such as AVCHD and DivX formats.Although sometimes compared to DivX products, …

The ASF container provides the framework for digital rights management in Windows Media Audio and Windows Media Video. An analysis of an older scheme used in WMA reveals that it is using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing function.

Image file formats are standardized means of organizing and storing digital images.An image file format may store data in an uncompressed format, a compressed format (which may be lossless or lossy), or a vector format. Image files are composed of digital data in one of these formats so that the data can be rasterized for use on a computer display or printer.

An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container …

An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter or card.. Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross or a kite.These shapes allow the envelope structure to be made by folding the sheet sides around a central rectangular area.

Preservatives and antioxidants may be incorporated into some food and drug products to extend their shelf life. Some companies use induction sealing and vacuum/oxygen-barrier pouches to assist in the extension of the shelf life of their products where oxygen causes the loss.. The DoD Shelf-Life Program defines shelf-life as The total period of time beginning with the date of …

MPEG-2 includes a Systems section, part 1, that defines two distinct, but related, container formats.One is the transport stream, a data packet format designed to transmit one data packet in four ATM data packets for streaming digital video and audio over fixed or mobile transmission mediums, where the beginning and the end of the stream may not be identified, such as radio …

In cryptography, PKCS #12 defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust.. A PKCS #12 file may be encrypted and signed. The internal storage containers, called "SafeBags", may also be encrypted and signed.

The original FAT file system (or FAT structure, as it was called initially) was designed and implemented by Marc McDonald, based on a series of discussions between McDonald and Bill Gates. It was introduced with 8-bit table elements (and valid data cluster numbers up to 0xBF) in a precursor to Microsoft's Standalone Disk BASIC-80 for an 8080-based successor of the NCR …
