Dolby Pro Logic
Dolby Pro Logic is a surround sound processing technology developed by Dolby Laboratories, designed to decode soundtracks encoded with Dolby Surround. The terms Dolby Stereo and LtRt (''Left Total'', ''Right Total'') are also used to describe soundtracks that are encoded using this technique. Dolby Stereo—also known as Dolby MP (''Motion Picture'') or Dolby SVA (''stereo variable-area'')—was developed by Dolby in 1976 for analog movie theater, cinema sound systems. The format was adapted for home use in 1982 as Dolby Surround when VCR#Stereo Sound and HiFi, HiFi capable consumer VCRs were introduced. It was further improved with the Dolby Pro Logic decoding system after 1987. The Dolby MP Matrix was the professional system that encoded four channels of film sound into two. This track used by the ''Dolby Stereo'' theater system on a 35mm optical stereo print and decoded back to the original 4.0 Surround. The same four-channel encoded stereo track was largely left unchanged a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Height Channel
Height channels are audio channels in surround sound multichannel audio. Height channels are located above the listening area and increase the sound field beyond the horizontal plane. Two systems that use height channels, Dolby Pro Logic#Dolby Pro Logic IIz, Dolby Pro Logic IIz and DTS (sound system)#DTS Neo:X, DTS Neo:X, which matrixes a front left and front right height out of the front left and front right channels. According to Dolby, non-directional ambient effects such as rain and wind are mapped to the height channels. This is similar to what is mapped to rear surround channels. In 2002, Dolby premiered a master of ''We Were Soldiers'' which featured a Sonic Whole Overhead Sound soundtrack. DTS-HD is a format which supports virtually any amount (over 2000) discrete channels for which a demonstration of an 11.2 system using four height channels was given at a Consumer Electronics Show. Tomlinson Holman's 10.2 surround sound, a format currently under development, uses 12 or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Command Component System
''Dimensia'' ( ) was RCA's brand name for their high-end models of television systems and their components (tuner (radio), tuner, VCR, CD player, etc.) produced from 1984 to 1989, with variations continuing into the early 1990s, superseded by the ProScan model line. After RCA was acquired by General Electric in 1986, GE sold the RCA consumer electronics line to Thomson SA which continued the Dimensia line. They are significant for their wide array of advanced features and for being the first television receiver systems to feature a built in computer, somewhat of an early incarnation of a smart TV, but without internet access (see Technological convergence). In 1985, RCA released the Digital Command Component System, a fully integrated audio system that permitted the full functionality of Dimensia audio components without a Dimensia monitor. The name "Dimensia" actually dates back to the early 1970s when RCA used the term for an enhanced spatial stereo effect which they called "Dim ...

Video Game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, game controller, controller, computer keyboard, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with Sound, audio complement delivered through loudspeaker, speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides Touch, tactile sensations). Some video games also allow microphone and webcam inputs for voice chat in online gaming, in-game chatting and video game livestreaming, livestreaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and PC game, comp ...

Negative Feedback
Negative feedback (or balancing feedback) occurs when some function (Mathematics), function of the output of a system, process, or mechanism is feedback, fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances. Whereas positive feedback tends to instability via exponential growth, oscillation or chaos theory, chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to List of types of equilibrium, equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing, can be very stable, accurate, and responsive. Negative feedback is widely used in Mechanical engineering, mechanical and electronic engineering, and it is observed in many other fields including biology, chemistry and economics. General negative feedback systems are studied in Control engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In mechanical and control engineering, a servomechanism (also called servo system, or simply servo) is a control system for the position and its time derivatives, such as velocity, of a mechanical system. It often includes a servomotor, and uses closed-loop control to reduce steady-state error and improve dynamic response. In closed-loop control, error-sensing negative feedback is used to correct the action of the mechanism. In displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. Following a specified motion trajectory is called servoing, where "servo" is used as a verb. The ''servo'' prefix originates from the Latin word ''servus'' meaning slave. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jim Fosgate
James M. Fosgate (December 5, 1937 – December 7, 2022) was an American inventor, engineer and businessman. The self-taught son of a television and radio repairman, Fosgate invented the first car amplifier in 1973 and founded Fosgate Electronics, now called Rockford Fosgate. After his departure from Rockford Fosgate in 1981, Fosgate remained active in the audio world, running Fosgate Laboratories and leading the team that created Dolby Pro Logic II. Fosgate was also the developer of one of the finest quadraphonic decoders, the TATE II 101A (see Stereo Quadraphonic for details), in collaboration with Peter Scheiber and Martin Willcocks, which was superseded by his 3601 decoder. Audio career Collaborating with four channel matrix pioneer Peter Scheiber early on gave Fosgate's company the edge to become one of the leaders in the Dolby Surround market.
