HDMI转YPBPR; HDMI转VGA;视频转换器
价格:400.00
视频转换器HDFURYPRO是一款为:老式LCD-TV,CRT,三枪投影机,DLP\LCD投影机,以及没有HDMI接口的各种显示设备,HDFURYPRO将为这些设备提供***无损的HDMI信号转换,以致完成数字向模拟信号的0损失桥接。产品介绍输入接口:HDMI1、HDMI2输出接口:VGA(RGBHV)、YPBPR(色差分量)输入模式:480I/P、576I/P、720P、1080I/P输出模式:YPBPR:480I/P、576I/P、720P、1080IVGA:VGA、XGA、SVGA、SXGA、UGA(***高可以支持到1920X1080对应分辨率)音频接口:L/R立体声输出、SPDIF数字光纤输出操作指南输入波动开关:H1、H2当拨动开关对准H1时,表示当前输入模式为HDMI1通道,将HDMI线材插入HDMI1端口,就可以享受***视频输出了;同理,将开关对准H2时,表示当前输入通道为HDMI2,请将需要的HDMI线插在HDMI2接口上。输出拨动开关:VGA、YUV(YPBPR)当波动开关对准VGA时,表示当前输出为VGA通道;当波动开关对准YUV时,表示当前输出为YPBPR通道。LED:蓝色,表示当前处于通电工作状态电源电压:直流DC5V(切忌不要将高于5V的电源插入HDfuryPro电源孔)产品附件:HDfuryPro主机一台、电源适配器一个、说明书一份、YPBPR线一条、音频线一条FAQ:1:HDfuryPro是个什么产品?——HDfuryPro是一款为只有VGA或者YPBPR接口的显示设备,桥接HDMI设备的高清视频转换器。HDMI通过HDfuryPro以后,转换成VGA或者YPBPR的高清晰信号,通过显示设备的接口重现影像。2:HDfuryPro的显示效果和市场是的VGA-BOX有什么区别?哪个更好?Q:HDfuryPro是专门针对***用户或者发烧级用户而设计开发的产品,只局限于高清影音系统里,因此,HDfuryPro追求的是***的显示效果,追求的是高清的享受,而不是和普通VGA-BOX那样追求价格,不注重高清的本质,那个更好,不用说了。3:HDfuryPro和市场上的HDMI转VGA/YPBPR的线材有什么区别?Q:市场上有不少HDMI转VGA的线材,或者转YPBPR的线材,且里面带有芯片处理,但是,是不是带有芯片就一定是好东西呢?NO。HDfuryPro采用的是国际***大型芯片设计公司设计的***的HDMI芯片,而不是山寨电视机里面用的低端低成本的HDMI***芯片。HDfuryPro里面的YPBPR输出芯片,采用世界***为***的三电平同步处理技术,这是这些转换线材或者同类产品无法做到的(该芯片价格极高,这让很多把利益放在***位的商家望而止步)。4:HDfuryPro和市场上价格昂贵的HDfury2有什么区别,为什么HDfury2价格这么高?Q:HDfuryPro和HDfury2相比,输入端多一路HDMI接口,因为现在有多台HDMI设备的人比比皆是;输出端采用的处理方式不一样,HDfuryPro采用分离的处理集成电路,HDfury2采用一颗芯片完成VGA和YPBPR输出功能(这个可以这样解释:HDMI传输为什么要用差分19针座子传送,而YPBPR为什么只用Y/PB/PR三条线传输?因为高清的信号频率极高,如果把信号放在一起,容易产生相互辐***扰,影响画质;同样,在VGA和YPBPR输出中,传输的都是HDMI输入进来的高速高频率的信号,如果放在一起,肯定要产生不必要的串扰,纵然是增加成本,如果是发烧产品,或者***产品,一定是要分开;如果单从产品成本的角度考虑,肯定用一颗芯片更经济,利润更大)。价格方面,两个原因:***、HDfuryPro之所以那么便宜,是因为设计师不是一个单纯的商人,更希望有更多的人能用上HDfuryPro;第二、HDfury2因为采用很老的芯片,目前已经停产多年,原厂不再供货,只能通过市场上购买积压货或者旧货,物以稀为贵,当然成本自然增加,所以售价很高。5:HDfuryPro为什么需要外接电源?而HDfury2则可以不用电源?Q:HDfuryPro采用的是真正的高清视频信号处理芯片,既然是高清晰的信号,运行起来肯定需要好散功率,为什么电脑CPU会发热严重,为什么微软的XBOX360会屡次三红,就是因为他里面芯片内核工作频率高,运行速度快,同样,1080P的数字高清信号在芯片里面运行,不发热或者不耗电,那才真是稀奇的事情呢?除非........这就是一个***产品和一个普通产品之间的差距。6:HDfuryPro的HDCP采用什么样的存放方式?HDfuryPro的HDCP采用芯片内置的方式,确保一颗芯片一个HDCP编码,因为内置,就让那些逃避叫HDCP专利费的人翻版盗用,同时,因为一对一的编码,不会造成因为HDCP盗版而无法让HDMI内部的高清晰影音画质受到影响。7:什么叫三电平同步简单的解释:可以兼容不同设备的YPBPR接口,三电平同步让HDfuruPro兼容性独领***。详细解释请参考下面:TheadventofHDTVhasbroughtanumberofnewconceptsandtechnologieswithit.Oneoftheconceptsputintopracticeistri-levelsync.Tri-levelsyncsolvessometraditionalproblemsfoundwithbi-levelsync.Althoughtri-levelsyncispreferablewiththenewtelevisionsystem,westillfindourselvesinterfacingtosystemscapableofhandlingonlybi-levelsync.Therefore,theneedexiststoconvertfromtri-leveltobi-levelsynconoccasion.ThisTechCornerwillacquaintthereaderwiththenewtri-levelsyncformatanditsrelati***hiptobi-levelsync.Bi-LevelSyncBi-levelsynchasbeenthestandardsynchronizationsignalingmethodforallformsofvideoincludingcomputervideo,compositevideo,S-video,andcomponentvideo.Bi-levelreferstotwolevels.Forsync,thismeansapulseh***ingtwovoltagelevels(ahighandlowlevel,relativelyspeaking),hencethename.Systemsusingbi-levelsyncareedgetriggered.Typically,thenegative-going,leadingedgeofthepulsetriggersthesynchronizationprocess(Figure1).Displaysystemsmust"look"forthisnegativegoingedgeinordertoidentifythemomentintimewhentore-synctherasterscanprocess.Mostwillrecallthatcomputergraphicca***sometimesoutputpositive-goingsync.Positive-goingsyncsignalthedisplaythatthegraphicslineratehaschangedtoanewformat.Lookingforthesyncpulsehasalwaysbeenoneofthe"trickiest"oftasksforthedisplaysignalprocessor.Itrequirescarefulbiasingofthesyncprocessingcircuitrysothatthesyncpulseismadeasdistinguishableaspossiblefromtheothervoltagelevelswithinthevideosignal.Aspartofthevideosignal,bi-levelsyncintroducesanunwantedDCcomponent(Figure2).Inprocessingofcomposite,S-video,orcomponentvideotheDCcomponentisnottootroublesomeandcaneasilybemanagedaspartofthenormalsyncseparationroutine.Whenbi-levelsyncisintroducedontoRGBvideochannels,theprocessismorecomplex.Insomesystems,syncisintroducedonthegreenchannelonly.Thisrequiresthatthesyncseparationprocessbeultraclean;inmostcases,however,itisnot.Usuallyaverynarrowsyncpulseremains.Residualsyncresultsfromincompleteremovalofthesyncinformationfromavideoprocessingchannel.SyncistypicallyimposedonthegreenchannelinRGsBsystems.Highdefinitioncomponentvideosignalscontainsynconeachchannel.DependingontheperformancecharacteristicsoftheDCrestorationcircuitrywithinthevideoprocessingchannel,someorallofthesyncpulsemaynotberemovedfromthegreenchannel.ResidualsynccausesthegreenchanneltobiasincorrectlywithrespecttoredandblueatthedisplayCRT,thuscausingacolorshift.EveninRGBsystemswheresyncisintroducedonallthreechannels,thereissomedifficultywithmaintainingc***istentprocessingbetweenthethreechannels.Again,***allDCshiftsintheblacklevelcausedbyresidualsynccandisturbthecolorbalanceorgainsofthevideochannels.Asignificantamountofpowerisusedbythebroadcasttran***ittertosendthesyncpulse.Polarityofthevideosignalisdesignedtominimizetheamountofpowerusedtotran***itsync.And,whileweh***enottran***ittedanalogversi***ofhighdefinitiontelevisionterrestrially,earlytestingdoneduringHDTVdevelopmentdem***tratedaneedtoimprovethemanagementofsynchr
