With this module, DVI based devices such as Computers (Mac/PC) with S/PDIF or analog stereo audio can readily connect to HDMI™ Display. The HD610 is not only a format converter but also an audio embedder, it will embed digital or analog audio into HDMI™ output and sync it with video.• 1x AT-HD610 unit• 1x 5V DC locking power supply unit (110/240v universal)• 1x User’s manual1.Turn on the AT-HD610. Connect the HDMI™ display to HDMI OUTPUT .2.Dial the rotary control MODE counterclockwise () from 0 to 7.3.The green STATUS LED will be bright and then dark to indicate the EDID learning is complete.4. Dial the rotary control MODE clockwise () from 7 to 0. DO NOT let the rotary control arrow pass 6, which will erase the just learned EDID and reset to default EDID.1. Only HDMI™ enabled TV sets with underscan/overscan* support, the full active video can be accurately displayed. Some HDMI™ HDTV sets may not support this feature. If underscan/overscan* is NOT supported, the top, bottom, left and right border of the active video may be screened, and the S/PDIF audio may not sound right.2. Analog stereo audio can merely support 2-channel audio. This version does NOT support 8-channel analog audio applications.3. S/PDIF audio input can support 2 out of the 8-channel audio input.4. S/PDIF only supports 48kHz audio sample rate. Other than this rate, the input digital audio should be adjusted to 48kHz in order to get audio signal correctly sent.*The underscan mode displays the full video frame, which reveals content on the edge that is recorded. In overscan, the field monitor zooms in to the area that would be visible on most televisions. Set the field monitor to underscan if your video will be viewed on a computer monitor or shown with a projector and also to look for light stands, micro-phones, and other unwanted objects on the edges of your shot. Set it to overscan to see how the video will look on a television.•Silicon Image Chip-Sets allow 99.99% compatibility with all the AV gear (we only use Best)•HDMI™ and HDCP 2.0 compliant •DVI video bandwidth up to 165MHz • Coaxial S/PDIF and Stereo analog audio input supportedINTRODUCTIONPACKAGE CONTENTSEDID LEARNINGNOTICEFEATURESModel NameAT-HD610TechnicalRole of usageConverter HDMI™ complianceHDMI™DVI complianceDVI 1.1HDCP complianceYes Video bandwidthSingle-link 165MHz (4.95Gbps)Video support1080p60, WUXGA 1920x1200@60Hz, UXGA 1600x1200@60Hz Audio supportStereo audio (analog and digital)PCB stack-up4-layer board (impedance control – differential 100W ; single 50W )Input TMDS signal1.2 Volts (peak-to-peak)Input DDC signal5 Volts (peak-to-peak, TTL)ESD protection[1] Human body – ±19kV (air-gap discharge) & ±12kV (contact discharge)[2] Core chipset – ±8kV Input1x DVI + 1x RCA + 1x 3.5mm Output1x HDMI™HDMI™ connectorType A (19-pin female)DVI connectorDVI-D (29-pin female digital only)RCA connectorCoaxial S/PDIF digital audio (PCM 48kHz)3.5mm connectorAnalog stereo audio Control switch2-pin DIP switch for mode selection MechanicalHousingMetal enclosure Dimensions [L x W x H]Model125 x 95 x 25mm (4.9” x 3.7” x 1”)Package175 x 270 x 80mm (6.9” x 10.6” x 3.1”)Weight Model350g (12 oz)Package815g (1.8 lbs)FixednessWall-mounting housing and latch-locking power jack Power supply5V DC Power consumption4 Watts (max)Operation temperature0~40°C (32~104°F)Storage temperature-20~60°C (-4~140°F]Relative humidity 20~90% RH (no condensation)SPECIFICATIONS1.

dvi转hdmi原理

dvi转hdmi原理

dvi转hdmi原理DVI(Digital Visual Interface)是一种数字视频传输接口,而HDMI(High-Definition Multimedia Interface)则是一种高清晰度多媒体接口。

DVI转HDMI是指将DVI接口的信号转换为HDMI 接口的信号,以便在高清电视、显示器或投影仪等设备上播放高质量的视频内容。

DVI接口最早出现在计算机领域,用于连接计算机和显示器。

它能够传输数字信号,提供较高的图像质量和分辨率支持。

然而,DVI 接口没有声音传输功能,只能传输视频信号。

为了解决这个问题,HDMI接口应运而生。

HDMI接口不仅可以传输高质量的视频信号,还可以传输音频信号,从而实现音视频一体化。

由于DVI和HDMI接口之间存在一些差异,因此需要使用DVI转HDMI的转接器或转换线缆来进行连接。

转换过程主要涉及以下几个方面的信号转换:1. 视频信号转换:DVI接口和HDMI接口都支持传输高清晰度视频信号,但信号格式略有不同。

DVI接口使用RGB(红绿蓝)格式传输视频信号,而HDMI接口则使用RGB或YCbCr(亮度和色度)格式传输。

转换器会将DVI接口的RGB信号转换为HDMI接口所需的RGB或YCbCr信号。

2. 音频信号转换:DVI接口没有内置的音频传输功能,而HDMI接口可以同时传输视频和音频信号。

因此,在DVI转HDMI的转换过程中,需要通过其他方式传输音频信号,例如使用额外的音频线缆或通过计算机的音频输出接口。

3. 数字模拟信号转换:DVI接口可以支持数字信号和模拟信号的传输,而HDMI接口只支持数字信号传输。

因此,在进行DVI转HDMI的转换时,需要将DVI接口的数字信号转换为HDMI接口所需的数字信号。

为了实现DVI转HDMI的转换,转接器或转换线缆通常会采用一些电路和芯片来处理信号转换和传输。

这些电路和芯片能够解析DVI 接口的信号,并将其转换为与HDMI接口兼容的信号。

The service enables installers and IT managers to deploy and manage thousands of devices in the amount of time it would ordinarily take to manage a single device.For more information, visit

目 前, 常 见 的 数 字 视 频 接 口 方 式 有 LVDS、 DVI 及 HDMI 等。 LVDS 是一种低压差分信号接 口, 其 支 持 速 率 仅 有 230Mbit / s ( 即 SXGA 分 辨 LVDS 视频接口无法提供内容保护机 率) ; 而且, LVDS 视频接口主要应用在便携系统 制。因此, 不适用于大尺寸高分辨率的 的小尺寸显示器上, 桌面显示器。 DVI / HDMI 视 频 接 口 可 达 到 相对 于 LVDS, UXGA 分辨率, 高于高清电视所需分辨率。 同时, DVI 可由 HDCP 实现内容保护功能, 而 HDMI 自 DVI / HDMI 视频接口 身包含 HDCP 内核。 因此, 已 广泛应用于 DVD 播放器 、 有线 / 卫星电视机顶

考虑到 DVI / HDMI 的图像分辨率较高, 必须 保证 TMDS 发送芯片与 FPGA 之间的传输带宽在 100MHz 以上, 因此 FPGA 的运行速率要足够快。 同时因 FPGA 和外围设备之间的交互比较多, 所 以要求 FPGA 有足够多的引脚。 由于采用的晶体 振荡器的时钟频率为 27MHz, 无法满足传输速率 所要求的 100MHz 以上, 因此需要 FPGA 内部带 为满足转换器的脱机工作, 需要 有锁相环。此外, 保证 FPGA 具备配置芯片。 另外, 考虑到转换器 , FPGA 的占用面积和版本升级 要求 具有足够丰 富的内部资源。 综合 考 虑, 最 终 选 用 Cyclon4 系 列 型 号 为 EP4CE40 的 FPGA。该 FPGA 具有高速 LVDS I / O 端口, 其运行速率可达 640Mbit / s, 低速 LVDS I / O 端口的运 行 速 率 也 有 311Mbit / s; 共 有 484 个 引 其中包括 328 个可用引脚; 4 个锁相环; 支持 脚, 串行配置芯片; 逻辑单元有 39 600 个; 存储空间
