教你玩转MP3视频（MTV、AMV、MPV、SMV格式的概念与区别
教你玩转MP3视频（MTV、AMV、MPV、SMV格式的概念与区别由于各种原因，目前视频MP3播放器的存储容量大多在512MB 以下，加上屏幕小、电池续航时间有限以及支持的视频解码技术存在版权等因素的限制，所以视频MP3对目前主流的视频格式如RMVB、WMV和***I等视频格式大多不支持，厂商一般都为自己的视频MP3播放器开发了体积小、适于小屏幕MP3播放的特殊视频格式。
现在视频MP3播放器专用的视频格式还没有统一的标准，在视频MP3播放器的发展过程中，一些公司研发出了多种可用于视频MP3播放器播放的视频文件格式。
就目前而言，一款视频MP3播放器大多只支持一两种视频格式，再加上各种视频格式文件所能达到的文件大小、画质各不相同，所以有必要先来了解一下这些视频格式的基本知识。
这对于购买适合自已的视频MP3播放器有很大帮助。
下面就来看看目前不同视频MP3播放器支持的主流视频格式。
1.MTV格式：这是视频MP3较早支持播放的视频格式，也是目前最常见的视频格式。
但其缺点也很明显，文件体积大，一分钟的MTV 格式文件约占12MB的容量，而且画面质量也欠佳。
MTV视频格式正逐渐被表现更好的AMV视频格式所取代。
2.AMV格式：相对于MTV格式来说，AMV视频格式比MTV视频格式有着更好的压缩比例以及画面质量。
通过AMV转换工具转换出来的影音文件一分钟的容量约为1.8MB。
也就是说，256MB的MP3播放器可存放130分钟的AMV格式的电影，这样用户就可将一部电影从头看到尾，真正让视频MP3播放器成为“电影播放机”，所以AMV视频格式正被广泛应用。
3.MPV格式：MPV是由柯达、HP、LG、奥林巴斯、飞利浦、三星和索尼公司等多家消费电子厂商为消费类电子产品和数字成像技术（音频、图像和视频）制定的一个标准。
MPV格式文件是由音频流和运动图像构成的多媒体文件，音频流的格式仍然选用了当今流行的 MP3 音频编码格式。

Empire Compressor MKII 压缩器说明书
USER MANUALIntroductionWhen we released our original Compressor back in 2011, it quickly became a favourite among guitar and bass players alike who were searching for something more than the typical oversimplified controls found on most compressor pedals. Now, based on our users’ valuable feedback, we’ve taken everything great about our original Compressor and made it even better.On top of the full range of features and controls normally only seen in high end studio equipment, such as input and gain reduction metering, independent attack and release controls, a mix knob for parallel compression, and an external sidechain insert, we’venow added a ‘tilt’ tone eq control, and a selectable sidechain high pass filter built into the Compressor’s detection circuit. Oh, and the whole package is now half the size. Who doesn’t love a small package?!We hope the Compressor MKII becomes a favourite of yours as well, and sincerely thank you for choosing Empress Effects.- Steve BraggQuickstartAdded Control: Here’sa good starting pointfor adding consistencyand sustain to yourplaying whileretaining dynamics.Adjust the input levelso the gain reductionmeter shows 8dB ofgain reduction whenplaying your loudest.Chicken Pickin’: Thisone provides a nicecompressed countrysound. Adjust theinput for 10dB ofgain reduction whenplaying your loudest.TransparentCompression: Thiswill give you nicedynamic controlto level out yourplaying. The 2:1 ratiois very transparent.It won’t really soundcompressed as muchas just sweeteroverall.Limiter: This settingwill eat up your pickattacks and createa smoother sound.You’ll also get lots ofsustain out of this.LevelThe Basics of CompressionCompression can add consistency and sustain to your playing or it can be used to add notedefinition and other effects. It essentiallynarrows the difference between high and low audio levels by reducing the gain of any signalover the threshold.The ratio determines how much gainreduction will be applied to the signal once it crosses above the threshold. At a 4:1 ratio, for every 4dB of input signal above the threshold, there will be 1dB of output signal. A 10:1 ratio would output 1dB for every 10dB of inputsignal, etc.input: sets the level entering the compressor circuit. Higher levels result in more compression.attack: controls how quickly the compressor will reduce the gain when an incoming signal exceeds the threshold. Attack time increases as you turn the knob clockwise. Range: 50μs - 50msControls atrelease: controls how quickly theor as a boost for soloing.t a GlanceAttack controls how quickly the gain reduction will begin after a signal has crossed over the threshold. Release controls how long it takes for the Compressor’s gain to return to its initial level after the signal drops below the threshold.SidechainThe sidechain is the Compressor’s level detection circuitry. Based on the signal sent to it, it will determine how much gain reduction is applied. Typically that signal is a copy of the input signal, taken from some point in the audio path. In our case it’s taken after the gain reduction has occurred, which is known as ‘feedback’ style compression. It can be very useful to alter the sidechain signal in order to tailor how the compressor reacts.Sidechain High Pass FilterThe sidechain hpf (high pass filter) switch can be engaged to avoid triggering the compression with high energy notes inthe lowest octave, which helps avoid over-compressing and keeps the low frequencies sounding full while still controlling errant high notes that pop out.Sidechain connector jackThe sidechain connector jack on the back of the pedal allows you to alter the sidechain signal by inserting an external device, such as an EQ. You can also have an external audio source trigger the compression by sending audio in through the ring of the sidechain jack.The sidechain connector accepts a 1/8” TRS plug: Tip = send, Ring = return, Sleeve = ground.Parallel CompressionThe mix knob on the Compressor MKII allows for parallel compression. Parallel compression is achieved by blending a compressed audioSetting the bypass state on startup To change whether the Compressor starts up in the engaged or bypassed state, hold down the stompswitch while powering on the Compressor. The first red gain reduction led will flash to let you know you are in the advanced configuration mode. Press the stompswitch to toggle between states:gain reduction led 1 = bypassed at startup gain reduction led 2 = engaged at startup When finished, press and hold the stompswitch for 2 seconds to confirm and save your selection, and exit advanced configuration.signal with the uncompressed version of itself. It opens up a ton of possibilities. A great use of parallel compression is to really squash the compressed signal (so it sounds way too over compressed), then use the mix knob to blend in some of the uncompressed signal. The result is very natural sounding, but feels a lot more exciting, with more sustain and retaining a good attack. Try experimenting with it!SpecificationsInput Impedance:1MΩOutput Impedance: 2.2kΩFrequency Response(-3dB):20Hz - 20kHz Distortion:<0.1% Noise:-101dB Headroom:+15dBu Input Voltage:9VDC Required Current:100mAPower Input Connector:2.1mm Barrel ConnectorHeight (enclosureonly): 1.5”Height (includingcontrols): 2.5”Length: 4.8”Width: 2.6”Weight:1lbsPowering the Compressor MKIIGo to /power for a full list of compatible power supplies.

Polytec OFV-5000 Vibrometer Controller说明书
OFV-5000 Vibrometer ControllerOFV-5000Vibrometer Controller– Velocity Decoders– Displacement DecodersOFV-505/503Standard SensorsOFV-511/512Fiber-Optic SensorsM E A S U R I N G V I B R A T I O N SPolytec’s modular vibrometer controller is continually improving to meet the needsof advanced vibration measurement applications. The latest design adds digitalprocessing with a range of new features that make non-contact vibration analysiseven more precise, simple, flexible and rewarding.OFV-5000 Controller –The Soul of a Quality Vibrometer SystemOFV-5000 replaces the widely respected OFV-3001 modular controller. Its advantages include improved vibration resolution and dynamic range from new digital/analog decoders, remote focus and focus memory (with OFV-505), more capacity for a wider range of modules and digital filtering. Polytec Laser Doppler Vibrometers operate on the Doppler principle, measuring back-scattered laser light from a vibrating structure, to determi-ne its vibrational velocity and displacement. A vibrometer system is comprised of controller electronics and a non-contact standard-optic or fiber-optic sensor head. The controller provides signals and power for the sensor head, and pro-cesses the vibration signals. These are electroni-cally converted by specially developed decoders within the controller to obtain velocity and displacement information about the test structure. This information is provided by OFV-5000 in either analog or digital form, for further data evaluation.Functionality and FlexibilityModular ApproachA wide range of configurations offers optimalperformance for the task with maximum flexi-bility and expandability to meet future needs.Application-Specific ConfigurationBy selecting from a choice of different analogand/or digital decoders, performance can beprecisely tailored to match the demands ofthe application.Several compatible standard-optic and fiber-optic sensor heads are available to meet specificneeds for robustness, flexibility and ease-of-use.Upgradeable to Scanning VibrometerOFV-5000 is fully upgradeable to Polytec’snew 1-D and 3-D Scanning Vibrometersystems for full field vibration analysis.Remote Focus FunctionsAutofocus, remote focus and focus memoryare all possible with the OFV-5000 controllerused with the new OFV-505 sensor head.M O D U L A RV I B R O M E T E RS Y S T E MBusiness UnitLaser Measurement SystemsTel.+49(0)7243 604-178Tel.+49(0)7243 604-104*************Flexible Signal ProcessingThe OFV-5000 controller is designed to accept a choice of signal processing modules, each optimized for different frequency, velocity or displacement performance.Each module is therefore tuned for different measurement tasks by making the best use of the vibration information in the Doppler signal obtained by the sensor head.Various analog and/or digital decoder options seamlessly cover the entire velocity range up to ±10 m/s, displacements from the sub-nanometer to the meter range, and frequencies from DC to 20 MHz. Up to four decoders can be installed simultaneously to obtain the greatest possible flexibility. This flexibility also allows retrospective add-ons and modifications to meet future needs.Laser Vibrometry Expansion Options, using the OFV-5000 ControllerVibrometer Measurement SystemA system comprises an OFV-5000 controller,choice of decoder modules and a sensor head.A choice of standard single point andfiber-delivered single point sensors, or dual (differential) fiber sensors is available.Expansion to Scanning Vibrometer SystemsA system based on the OFV-5000 can be extended to a full scanning vibrometer system by adding other components.The Polytec Scanning Vibrometer (PSV) makes it possible to rapidly and automatically acquire vibration characteristics of complete surfaces,while the PSV-3D extends this to three-dimensional data acquisition and analysis. The Micro-Scanning Vibrometer and Micro Motion Analyser (MMA)have been developed to perform the same measurements on microstructures.Velocity Decoders Displacement Decoder Auxiliary DecoderDSP FilterSlot 1Slot 214-bit or16-bit FCDSP *Velocity or DisplacementVD-01–DD-100orDD-200–VD-05**DD-300–VD-02–––VD-02VD-06DD-500**LF-02VD-04–––VD-04VD-06DD-500**LF-02–VD-06DD-500**DD-400 or DD-300LF-02DD-300Table of Decoder Combinations*Instead of the internal displacement decoder, a DD-600 I&Q demodulator for external PC-based signal processing can also be installed (VibSoft-VDD)**from 2004 onwardsDisplacement DecodersDD-100 and DD-200 analog 14 bit dis-placement decoders take phase information from the Doppler signal to provide direct displacement signals, not derived from the velocity information. They may be used in conjunction with velocity decoders toprovide full vibration characterization of the test structure.Alternatively, OFV-5000 accepts the DD-500A further option is the DD-600 I&Q demodulator. This is designed to allow processing of the digital signal with the PC-based VibSoft-VDD package. This pro-vides the highest resolution and dynamic range of all the displacement decoder options.DD-300 and DD-400 decoders are designed for use in the Auxiliary Slot. The highfrequency DD-300 measures between 50 kHz and 20 MHz. The VD-400 employs an analog integrator.DSP FilterThe DSP based adaptive filter module significantly improves the signal-to-noise ratio of the vibration signal by suppressing random and non-periodic noise forfrequencies ranging from DC to 20 kHz. The adaptive filter can only be used inconjunction with the digital decoder VD-06.Selection and Combination of Signal DecodersThe OFV-5000 controller has four internal slots to accept up to four different signal decoders, depending on the desired measure-ment ranges. Two are specifically designated for velocity decoders and one is for the displacement decoder. An Auxiliary Slot is provided to take a further optional velocity or displacement decoder.sales or application engineer who will help you to select the appropriate decoders and VibSoft Software.Velocity DecodersThe VD-01 velocity decoder offers the highest linearity for frequencies up to 50 kHz. The VD-02 has an extended range up to 1.5 MHz. The VD-04 3-range decoder is required if the DD-400 analog integrator displacement decoder is selected. VD-05 is intended for use in the Auxiliary Slot, and with a frequency response to 10 MHz is par-ticularly well suited for ultrasonics applications.For the very best precision in the low velocity region (up to 500 mm/s), we recommend the VD-06 digital decoder.Decoders can be used together. For example VD-02 used together with VD-06 will give the greatest dynamic range and optimal frequency and velocity performance. Alter-natively, a DD-400 displacement integrator with VD-04, plus VD-06 will give velocity and displacement.Outputs analog On the front: Velocity out, Displacement out, DSP out, Auxiliary out; On the back: Signal level out Interface RS-232Ambient temperature +5 °C to +40 °C Storage temperature –5 °C to +60 °CPower supply Switch mode power supply with wide range input 100 ... 240 V Display Outputs digitalIlluminated graphics LCD with menu assistance S/P-DIF optical and electricalRelative humidity 20 % to 80 %, non-condensingWeight9.7 kgDimensions [W x H x L]450 mm x 360 mm x 145 mm (19” housing)OFV-5000 Technical DataGeneral Specifications Standard single point sensor heads OFV-505, OFV-503 (also OFV-303, OFV-353)Fiber optic sensor headsOFV-511, OFV-512Sensor Head Compatibility Polytec GmbH Polytec-Platz 1-776337 Waldbronn GermanyTel.:+49(7243) 604-0Fax:+49(7243) 69944E-Mail:*************LambdaPhotometrics Ltd.Lambda House, Batford Mill HarpendenHertsfordshire AL5 5BZ Great BritainTel.:+44(1582)764334Fax:+44(1582)712084E-Mail:*******************.uk Polytec PI, S.A.32 rue Delizy93694 PANTIN Cédex FranceBusiness UnitLaser Measurement Systems Tel.+49(0)7243 604-178Tel.+49(0)7243 604-104*************OFV-505/503 Vibrometer Sensor HeadOFV-5000Vibrometer Controller – Velocity Decoders– Displacement Decoders OFV-505/503 Standard Sensors OFV-511/512Fiber-Optic SensorsM E A S U R I N G V IB RA T I O N SPolytec Laser Doppler Vibrometers are used to precisely measure mechanical vibrations, quickly, easily and free from cross-talk or feedback problems.

The data latch section of Q4014 also receives serial dividing data from microprocessor Q1009 on CNTL Unit 1, which causes the pre-divided VCO signal to be further divided by 11,240 - 15,240 in the programmable. divider section, depending upon the desIred receive frequency, so as to produce a 10-kHz or 12.5 kHz derivative of the current VCO frequency. Meanwhile, the reference divider section of Q4014 divides the 12.8 MHz crystal reference by 1280 (or 1024) to produce the 10-kHz (or 12.5-kHz) loop reference.

MPU-2说明书概述
MPU-2型恒功率晶闸管中频电源控制板使用说明书小芯片六脉波1、概述MPU-2恒功率晶闸管中频电源控制板主要由电源、调节器、移相控制、保护电路、相序自适应电路、启动演算电路、逆变频率跟踪、逆变脉冲形成、脉冲放大及脉冲变压器组成。
其核心部件采用高性能、高密度、大规模专用MPU集成电路，使其电路除调节器外，其余均实现数字化，整流触发器部分不需要任何调整，具有可靠性高、脉冲对称度高、抗干扰能力强、反应速度快等特点，又由于有相序自适应电路，无需同步变压器，所以，现场调试中免去了调相序、对同步的工作，仅需把KP 晶闸管的门极线接入控制板相应的接线端上，整流部分便能投入运行。
逆变采用扫频式零压软启动方式，启动性能优于普通的零压软启动电路。
并设有自动重复启动电路，可防止中频电源偶尔的启动失败，使启动成功率达到100%。
频率跟踪电路采用的是平均值取样方案，提高了逆变的抗干扰能力，而且仅需取样中频电压信号，而无需槽路电容器的电流信号，免去了外接中频电流互感器、确定取样电流相位的烦恼。
因此，在调试和使用现场中，也不会由于中频输出线或取样电流互感器的相位接反，而产生中频电源不能启动的问题。
逆变电路中还加有逆变角调节电路，可以自动调节负载阻抗的匹配，达到恒功率输出，可以制成“快速熔炼”的中频电源，达到节时、节电、提高网侧功率因数的目的（此功能也可被送掉）。
逆变部分的主要电路均在MPU-2大规模集成电路的内部，亦是数字电路。
MPU-2控制板全板仅有7只集成电路、6只晶体管、6只微调电位器、32个引出端子，安装十分方便，适用于各种晶闸管并联谐振中频电源。
MPU-2控制板在设计中征求了多方面的意见，采取了有效措施，使得调试极为方便，大多数参数的都由电路内部自动设定，需要用户调整的只有6只电位器的参数设定，所以具有极强的通用性和互换性。
