The Yamaha DSP-1 is a processor of early home theater surround sound equipment, produced in 1986. [1] The DSP-1 (referred to by Yamaha as a Digital Soundfield Processor) allowed owners to synthesize up to 6-channels of surround sound from 2 channel stereo sound via a complex digital signal processor (DSP).
Devices designed for Enigma2 (i.e. satellite receivers, set-top boxes and IPTV receivers, often simply called boxes) are equipped with one or more DVB-S, DVB-C and DVB-T tuner(s) (unless they are pure IPTV receivers), a Remote control receiver and an Ethernet and/or Wi-Fi network adapter. To receive coded/scrambled programs the box may be ...
An integrated receiver/decoder (IRD) is an electronic device used to pick up a radio-frequency signal and convert digital information transmitted in it. Consumer IRDs [ edit ]
When the receiver/decoder interprets the sign using the same logic as the encoder, it can be called a “preferred reading” (Meagher 185). [ 6 ] In the oppositional position (the least symmetrical decoding position), “the viewer recognizes the preferred reading that has been constructed by producers, but rejects it in its totality ...
The ASI output of a DVB Integrated Receiver/Decoder (IRD). It carries the entire MPEG transport stream being received from a DVB satellite feed entering the RF input (far left side in picture). Asynchronous Serial Interface, or ASI, is a method of carrying an MPEG Transport Stream over 75-ohm copper coaxial cable or optical fiber. [1]
The code-rate is hence a real number. A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.
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) must agree ahead of time on a decoding convention. Popular conventions include: Request that the codeword be resent – automatic repeat-request.
Repetition codes are one of the few known codes whose code rate can be automatically adjusted to varying channel capacity, by sending more or less parity information as required to overcome the channel noise, and it is the only such code known for non-erasure channels.
