Audio Decoder
An audio codec is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. In software, an audio codec is a computer program implementing an algorithm that compresses and decompresses digital audio data according to a given audio file or streaming media audio coding format. The objective of the algorithm is to represent the high-fidelity audio signal with minimum number of bits while retaining quality. This can effectively reduce the storage space and the bandwidth required for transmission of the stored audio file. Most software codecs are implemented as libraries which interface to one or more multimedia players. Most modern audio compression algorithms are based on modified discrete cosine transform (MDCT) coding and linear predictive coding (LPC). In hardware, audio codec refers to a single device that encodes analog audio as digital signals and decodes digital back into analog. In other words, it contains bot ...

Binary Decoder
In digital electronics, a binary decoder is a combinational logic circuit that converts binary information from the n coded inputs to a maximum of 2n unique outputs. They are used in a wide variety of applications, including instruction decoding, data multiplexing and data demultiplexing, seven segment displays, and as address decoders for memory and port-mapped I/O. There are several types of binary decoders, but in all cases a decoder is an electronic circuit with multiple input and multiple output signals, which converts every unique combination of input states to a specific combination of output states. In addition to integer data inputs, some decoders also have one or more "enable" inputs. When the enable input is negated (disabled), all decoder outputs are forced to their inactive states. Depending on its function, a binary decoder will convert binary information from n input signals to as many as 2n unique output signals. Some decoders have less than 2n output lines; in ...

Codec
A codec is a device or computer program that encodes or decodes a data stream or signal. ''Codec'' is a portmanteau of coder/decoder. In electronic communications, an endec is a device that acts as both an encoder and a decoder on a signal or data stream, and hence is a type of codec. ''Endec'' is a portmanteau of encoder/decoder. A coder or encoder encodes a data stream or a signal for transmission or storage, possibly in encrypted form, and the decoder function reverses the encoding for playback or editing. Codecs are used in videoconferencing, streaming media, and video editing applications. History In the mid-20th century, a codec was a device that coded analog signals into digital form using pulse-code modulation (PCM). Later, the name was also applied to software for converting between digital signal formats, including companding functions. Examples An audio codec converts analog audio signals into digital signals for transmission or encodes them for storage. A receiv ...

Instruction Decoder
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other c ...

Quadrature Decoder
An incremental encoder is a linear or rotary electromechanical device that has two output signals, ''A'' and ''B'', which issue pulses when the device is moved. Together, the ''A'' and ''B'' signals indicate both the occurrence of and direction of movement. Many incremental encoders have an additional output signal, typically designated ''index'' or ''Z'', which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated ''alarm'') that indicates internal fault conditions such as a bearing failure or sensor malfunction. Unlike an absolute encoder, an incremental encoder does not indicate absolute position; it only reports changes in position and, for each reported position change, the direction of movement. Consequently, to determine absolute position at any particular moment, it is necessary to send the encoder signals to an '' incremental encoder interface'', which in turn will "track" and report the enc ...

Video Decoder
A video decoder is an electronic circuit, often contained within a single integrated circuit chip, that converts base-band analog video signals to digital video. Video decoders commonly allow programmable control over video characteristics such as hue, contrast, and saturation. A video decoder performs the inverse function of a video encoder, which converts raw (uncompressed) digital video to analog video. Video decoders are commonly used in video capture devices and frame grabbers. Signals The input signal to a video decoder is analog video that conforms to a standard format. For example, a standard definition (SD) decoder accepts (composite or S-Video) that conforms to SD formats such as NTSC or PAL. High definition (HD) decoders accept analog HD formats such as AHD, HD-TVI, or HD-CVI. The output digital video may be formatted in various ways, such as 8-bit or 16-bit 4:2:2, 12-bit 4:1:1, BT.656 (SD) or BT.1120 (HD). Usually, in addition to the digital video output bus, a v ...

Decoder (band)
Decoder was an American post-hardcore band formed in 2010 in Florida. The group consisted of former members of the bands Versa, Polyenso, and Of Machines. Decoder were signed to Rise Records and released one album. The group performed mellow and slow tempoed post-rock and ambient-influenced instrumentals coupled with screamed vocals and heavy percussion. On March 1, 2012, the band changed their name from Decoder to Lead Hands, settling a lawsuit of the group's original name due to a band from New Jersey of the same name. However, shortly after the name change to Lead Hands, the band disbanded. History Inception and signing to Rise Records (2010) Decoder was an idea that came about when drummer Brent Guistwite, formerly of Of Machines, and Jack Burns, formerly of Oceana parted ways with their respective bands. They had the style and concept for the music decided before they approached Keith Jones, formerly of Oceana, and Spencer Pearson, formerly of VersaEmerge, to be the b ...

Decoder (duo)
Decoder is the collective stage name of drum and bass/jungle producers Darren Beale and Mark Caro. Biography Beale started his career in 1991 using various aliases creating some old school hardcore tracks. He continued with fine tuning the deep jungle sounds under the Orca and Koda aliases on Lucky Spin Records and its sister label, Deejay Recordings, releasing "Tranquility to Earth" in 1994. In 1995 he first used the Decoder pseudonym, pioneering the dark or 'tech step' style of drum & bass, often on Mark Caro's label Tech Itch Recordings. 1997 saw release of Decoder's ''Decoded EP''. Decoder's releases appeared on various labels, including Breakbeat Culture with Markee Ledge as Decoder & Substance, Tech Itch Recordings, BS1 Records, Hard Leaders, 31 Records and Audio Couture.

Decoder (film)
''Decoder'' is a 1984 West German film directed by Muscha. It is a cyberpunk and counter-cultural film roughly based on the writings of William S. Burroughs, who also acts in the film. Bill Rice plays Jaeger ("Hunter"), an agent of the government in charge of suppressing dissidents, while FM Einheit plays a burger shop employee who discovers that by changing the background music from pleasantly calming to industrial "noise" music, he can incite riots and a revolution against the looming power of the government. ''Decoder'' was made on a small budget, and was written by Muscha, Klaus Maeck, Volker Schäfer, and Trini Trimpop. Nevertheless, the project was able to attract a number of notable people within the countercultural and industrial music "scenes" to perform in it. Actors included Burroughs, Genesis P-Orridge, Christiane Felscherinow, and bands included Soft Cell, Psychic TV, Einstürzende Neubauten, and The The. The film was considered "oddly forgotten", and for nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoding Methods
In coding theory, decoding is the process of translating received messages into codewords of a given code. There have been many common methods of mapping messages to codewords. These are often used to recover messages sent over a noisy channel, such as a binary symmetric channel. Notation C \subset \mathbb_2^n is considered a binary code with the length n; x,y shall be elements of \mathbb_2^n; and d(x,y) is the distance between those elements. Ideal observer decoding One may be given the message x \in \mathbb_2^n, then ideal observer decoding generates the codeword y \in C. The process results in this solution: :\mathbb(y \mbox \mid x \mbox) For example, a person can choose the codeword y that is most likely to be received as the message x after transmission. Decoding conventions Each codeword does not have an expected possibility: there may be more than one codeword with an equal likelihood of mutating into the received message. In such a case, the sender and receiver(s) mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
