GV7704
The GV7704 is a quad channel serial digital video receiver for High Definition component video. With integrated high performance cable equalizer technology, the GV7704 is capable of receiving HD video at 270Mbps and 1.485Gbps over 75Ω coaxial cable, or differentially over a 100Ω twisted pair cable.
The GV7704 integrates the High Definition Visually Lossless CODEC (HD-VLC™) technology, which has been developed specifically to reduce the transmission data rate of HD video over both coaxial and unshielded twisted pair (UTP) cable. This is achieved by encoding the HD video, normally transmitted at a serial data rate of 1.485Gbps, to the same rate as Standard Definition (SD) video, at 270Mbps serial data rate.
At 270Mbps, the effect of cable loss is greatly reduced, resulting in much longer cable transmission. For 75Ω coaxial cable, cable reach can be extended up to four times the normal reach when transmitting encoded HD at 270Mbps. In typical video over coaxial installations, cable distances of up to 500m are possible.
The GV7704 can also be configured to receive HD video over UTP cable, such as Cat-5e and Cat-6 cable, when HD-VLC encoded at 270Mbps.

无论您是在体育场的巨型屏幕上观看棒球比赛的动作回放、在大屏幕电视上观看电影，还是在笔记本电脑上播放视频，都期望获得高质量的视听 (AV) 体验。超高清串行数字接口 (UHD-SDI) 和高清多媒体接口 (HDMI) 是数字 AV 传输的两个标准。UHD-SDI 对通过同轴电缆或光纤传输未压缩和未加密的数字 AV 信号加以标准化。HDMI 是一种数字接口，用于将高清、高速数字多轨音频和未压缩视频信号从 HDMI 兼容源传输到视听显示器。尽管二者都可以将超高清 AV 信号从信号源传输到显示器，但 HDMI 更适合连接电脑、游戏机、蓝光/DVD 播放器、电视、投影仪等消费电子产品。 UHD-SDI 是专业室内/室外视频制作和电视广播等高端应用的首选，因为它支持远距离传输，并借助电缆两端的物理锁定机制实现可靠连接。UHD-SDI 同轴电缆可以将信号传输远达 300 英尺，而 HDMI 电缆即使在 50 英尺以内也会出现信号过渡衰减的问题。这两种接口可以通过 HDMI-SDI 或 SDI-HDMI 转换器一起使用。例如，如图 1 所示，HDMI 显示器用于 SDI 流的置信度监控，从而无需使用经过专门校准的 SDI 专用显示器。
