Что (кто) такое lossless coding - определение

EXTENSION TO THE MPEG-4 PART 3 (MPEG-4 AUDIO) STANDARD

HD-AAC; Hd-aac; Scalable Lossless Coding

Lossless join decomposition

DECOMPOSITION OF A DATABASE RELATION SUCH THAT A NATURAL JOIN OF THE RESULTING RELATIONS YIELDS BACK THE ORIGINAL RELATION

Lossless-join decomposition; Lossless-Join Decomposition

In database design, a lossless join decomposition is a decomposition of a relation R into relations R_1, R_2 such that a natural join of the two smaller relations yields back the original relation. This is central in removing redundancy safely from databases while preserving the original data.

Coding region

PORTION OF A GENE'S DNA OR RNA, COMPOSED OF EXONS, THAT CODES FOR PROTEIN; COMPOSED OF CODONS, WHICH ARE DECODED, TRANSLATED INTO PROTEINS BY THE RIBOSOME; BEGINS WITH THE START CODON AND END WITH A STOP CODON

Coding sequence; Coding regions; Coding DNA sequence; Protein coding region; Protein coding sequence; Gene coding; Coding DNA; Protein-coding

The coding region of a gene, also known as the coding sequence (CDS), is the portion of a gene's DNA or RNA that codes for protein. Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene organization and evolution of prokaryotes and eukaryotes.

Coding conventions

STANDARDS AND GUIDELINES FOR WRITING CODE

Coding standard; Code convention; Coding standards; Code conventions; Trailing comma

Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language. These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventions, programming practices, programming principles, programming rules of thumb, architectural best practices, etc.

MPEG-4 SLS

MPEG-4 SLS, or MPEG-4 Scalable to Lossless as per ISO/IEC 14496-3:2005/Amd 3:2006 (Scalable Lossless Coding), is an extension to the MPEG-4 Part 3 (MPEG-4 Audio) standard to allow lossless audio compression scalable to lossy MPEG-4 General Audio coding methods (e.g., variations of AAC). It was developed jointly by the Institute for Infocomm Research (I²R) and Fraunhofer, which commercializes its implementation of a limited subset of the standard under the name of HD-AAC. Standardization of the HD-AAC profile for MPEG-4 Audio is under development (as of September 2009).

MPEG-4 SLS allows having both a lossy layer and a lossless correction layer similar to Wavpack Hybrid, OptimFROG DualStream and DTS-HD Master Audio, providing backwards compatibility to MPEG AAC-compliant bitstreams. MPEG-4 SLS can also work without a lossy layer (a.k.a. "SLS Non-Core"), in which case it will not be backwards compatible, Lossy compression of files is necessary for files that need to be streamed to the Internet or played in devices with limited storage.

With DRM, ripping of the lossless data or playback on non DRM-enabled devices could be disabled.

MPEG-4 SLS is not related in any way to MPEG-4 ALS (Audio Lossless Coding).
