 如何识别联基产品：1. 产品的接头或线身上有FREEPORT商标。2. 线材的接头上有模具成型的EDA标志：3. 线身印字带有美国UL编号：E256295

 

功能特点
　　HDMI不仅可以满足1080P的分辨率，还能支持DVD Audio等数字音频格式，支持八声道96kHz或立体声192kHz数码音频传送。 　　HDMI支持EDID、DDC2B，因此具有HDMI的设备具有“即插即用”的特点，信号源和显示设备之间会自动进行“协商”，自动选择合适的视频/音频格式。 　　与DVI相比HDMI接口的体积更小，DVI的线缆长度不能超过8米，否则将影响画面质量，而HDMI远可传输15米。只要一条HDMI缆线，就可以取代多13条模拟传输线，能有效解决家庭娱乐系统背后连线杂乱纠结的问题。
产品特点:

 

1). 联基dp转HDMI线，支持音频与视频同步输出，显卡本身必须有数字音频功能.

 

2).联基dp转HDMI线，采用原装美国Parade芯片(PS8121E)，传输稳定、兼容、无得叹！

 

3).兼容性超好:独显与集成显卡，XP系统和WIN7系统都兼容.

 

4).支持HDMI所版本的高清电视、投影仪、显示器.

 

5).插头严格按照Dislplayort标准彩锁扣设计；支持热插拔.

 

6).加一个HDMI转DVI转接头可接DVI口显示器

 

注意事项

 

1、DP转HDMI产品芯片设计只能DP向HDMI转换；dp口在显示器不能用。

 

2、电脑DP没支持音频解决方案:用音频线连接电脑音箱或功放音响!(电视有模拟音频也可接电视)
Digital interface defined around DVI 1.0 that transmits video and audio on the same physical channel. 　　 Interface defined for use in the consumer market space. 　　zRequires separate licensing from that of DDWG’s DVI. 　　zAllows DVI/HDMI products to be sold in consumer products 　　 Supports the use of HDCP copy protection. 　　 Utilizes VESA’s Display Data Channel to read E-EDID from a display. 　　 Defines a different connector from that used on DVI. 　　 Supports optional CEC (Consumer Electronics Control), which allows high level control of all A/V products in a user environment. 　　DVI 1.0: The Physical Interface 　　 Digital Visual Interface (DVI) was developed by a group called the Digital Display Working Group or DDWG for the PC market. 　　 The interface is a high speed digital serial interface based on Transition Minimized Differential Signaling or TMDS. 　　zSource synchronous architecture. Uses a separate channel to transmit the clock. 　　zUsed to provide variable data rates to handle the various VESA supported display resolutions. 　　 A complete connection from the source to the sink devices uses three data channels (RGB/YCbCr) and a clock. 　　HDMI = DVI Audio 　　 Using the DVI physical link to transmit video/graphics 　　 Audio is added as a logical layer to the DVI phy. 　　zDigital audio processed into packets of data 　　zThese packets are scheduled for transmission during existing horizontal and vertical blanking times within a frame. 　　 In addition, HDMI implements a packet called an infoFrame. 　　zInfoFramesare structures defined in the EIA-861B specification 　　zEIA-861B is spec for DTV and uncompressed high speed digital interfaces. 　　What is HDMI Data? 　　 There are three categories of data that is transmitted via an HDMI link. 　　zVideo Data –Video pixel data (8b data encoded to 10b), and Guard Bands (fixed 10b pattern) 　　zData Island –Packet data, which can be either audio samples or Infoframes(TERC4 encoded, 4b encoded to 10b) as well as its own Guard Band (fixed 10b pattern). 　　zControl –Control period coding, in which we find HSYNC, VSYNC (2b to 10b encoding) and a Preamble (used to determine whether subsequent data is video or data island) 　　Transmission of Video/Graphics 　　 HDMI transmits 24bit pixel data via three separate channels. 　　 Pixel rates supported are 25MHz to 165MHz. 　　zThis is exactly the same as single link DVI 1.0 　　 Also supports video rates below 25MHz e.g. 13.5MHz for 480i NTSC signals. 　　zAchieves this through a “pixel-repetition”scheme. 　　 Can handle pixel data in RGB, YCbCr(4-4-4), YCbCr(4-2-2) formats. 　　zIn all cases 24 bits of data per pixel clock are transmitted. 　　Transmission of Audio 　　 Basic Audio is provided via an IEC60958 audio stream at 33kHz, 44.1kHz, or 48kHz. 　　zAccommodates any normal stereo audio stream. 　　 Optionally this stream can be sent as a single channel at 192kHz. 　　 Can support IEC61937 compressed formats as found in surround-sound, Dolby Digital, etc. at rates up to 192kHz. 　　Infoframes and HDMI 　　 EIA/CEA-861B specifies a special packet called an infoframe 　　 HDMI sources and sinks are expected to use two basic infoframes. 　　zAVI (Auxiliary Video Information) Infoframe 　　 Communicates Colorimetry, Picture aspect ratio, Pixel-Repetition factor, RGB or YCbCrindicator, and others specified within 861B standard. 　　zAudio Infoframe 　　 Communicates, Channel count, Coding Type, Sample size, Sample frequency, Channel allocation and other audio specific information. 　　 There are other types of infoframes that are supported by the 861B standard, but are optional with respect to HDMI specification.
