Resource Interchange File Format (RIFF) is a generic file container format for storing data in tagged chunks. [2] It is primarily used for audio and video, though it can be used for arbitrary data. [3] The Microsoft implementation is mostly known through container formats like AVI, ANI and WAV, which use RIFF as their basis. [4]
A chunk is a fragment of information which is used in many multimedia file formats, such as PNG, IFF, MP3 and AVI. [1] Each chunk contains a header which indicates some parameters (e.g. the type of chunk, comments, size etc.). Following the header is a variable area containing data, which is decoded by the program from the parameters in the ...
A variable-length quantity (VLQ) is a universal code that uses an arbitrary number of binary octets (eight-bit bytes) to represent an arbitrarily large integer.A VLQ is essentially a base-128 representation of an unsigned integer with the addition of the eighth bit to mark continuation of bytes.
Overhead. This is the difference in file-size between two files with the same content in a different container. Support for advanced codec functionality. Older formats such as AVI do not support new codec features like B-frames, VBR audio or VFR video natively. The format may be "hacked" to add support, but this creates compatibility problems.
In chunked transfer encoding, the data stream is divided into a series of non-overlapping "chunks". The chunks are sent out and received independently of one another. No knowledge of the data stream outside the currently-being-processed chunk is necessary for both the sender and the receiver at any given time.
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
external sorting algorithm. External sorting is a class of sorting algorithms that can handle massive amounts of data.External sorting is required when the data being sorted do not fit into the main memory of a computing device (usually RAM) and instead they must reside in the slower external memory, usually a disk drive.
File formats often have a published specification describing the encoding method and enabling testing of program intended functionality. Not all formats have freely available specification documents, partly because some developers view their specification documents as trade secrets, and partly because other developers never author a formal specification document, letting precedent set by other ...
