DVI(数字视觉接口)和 HDMI(高清多媒体接口)已成为连接 PC
显示器和高清电视等数字显示设备的主导标准。 DVI 仅传输未压缩的视频数据,而 HDMI 可以通过单根电缆传输未压缩的数字视频和多通道音频。 HDMI 专为满足消费电子市场的独特需求而开发,提供了额外的增强功能,包括支持 YCbCr 色彩空间格式以及通过消费电子控制 (CEC) 协议实现的通用远程控制功能。支持 HDMI 的显示设备向后兼容基于 DVI 的 PC,因此用户可以在 HDTV 上显示 PC 内容。两种参考设计均已使用 LatticeECP3 视频协议板和 HDMI 夹层卡进行了验证。该参考设计由 HDMI 发送器和接收器内核组成,兼容 HDMI 和 DVI

DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface) have emerged as the dominant standards for connecting digital display devices like a PC monitor and HDTV. DVI only carries uncompressed video data, whereas HDMI can transfer both uncompressed digital video and multi-channel audio over a single cable. Developed specifically to address the unique requirements of the consumer electronics market, HDMI offers additional enhancements including the support of the YCbCr color space format, and the universal remote control capability through Consumer Electronics Control (CEC) protocol. HDMI-enabled display devices are backward-compatible with DVI-based PCs so users can display the PC contents on their HDTV. Both reference designs have been validated using the LatticeECP3 Video Protocol Board and HDMI Mezzanine Card. The reference design consists of the HDMI Transmitter and Receiver cores which are compatible with both HDMI and DVI physical layer protocols
