    适于六台 SVSI N 系列卡单元的 2RU 机架安装插件框架(含电源)

NMX-ENC-N2151 4K 编码器和 NMX-DEC-N2251 4K 解码器为用户提供业界功能最齐全的统合网络音视馈送解决方案,最高分辨率可达 4096×2160。JPEG2000 压缩使超高清媒体内容能够通过标准千兆以太网网络进行切换和馈送。下列情况下同步提供 NMX-ENC-N2151 编码器超高清信号:1)经 JPEG2000 压缩的 200-600Mbps 内容流经 RJ-45 接口或 SFP+ 端口;以及 2)未压缩内容(通过光纤 SFP+ 模块)流经小型可插式 (SFP+) 接口。通过第三层交换机,可将任何信源发送至任何数量的显示器。系统可扩展性仅受限于上行和堆叠接口带宽,但最多可同时处理 100 个超高清视频源。

所包含的标准功能有输出缩放(解码器)、双向串行、红外、嵌入式 7.1 音频和 IP KVM 扩展。NMX-ENC-N2151-C 和 NMX-DEC-N2251-C 结构均兼容高密度应用环境下的 NMX-ACC-N9206 插件框架。


NMX-ENC-N2151 和 NMX-DEC-N2251 相结合即可为需要高达 4K 分辨率的视频矩阵应用环境提供完美解决方案。常见应用环境包括教室、会议室、表演艺术中心和运动吧。
