Ellipse 1000 (ELP1000) 对于通过 IP 和传统 ATM/PDH/SDH 网络进行固定回传应用是一个理想的选择；作为一款专业、高品质的编码器，Ellipse 1000 为高质量视频传输提供了有效的比特率利用。Ellipse 1000 对馈入视频可同时以 MPEG-2 标清 4:2:0/4:2:2 和 MPEG-4 AVC 标清 4:2:0 格式进行编码压缩，提供了一条从 MPEG-2 CBR 到 MPEG-4 AVC CBR 编码方式的平滑和经济有效的迁移路径。Ellipse 1000 还可以通过 firmware 升级至 MPEG-4 AVC 高清，从而使其成为可用的最通用的编码器之一，并进一步扩展其迁移路径。经过现场验证、易于使用的 Ellipse 1000 可以经济有效地独立运行，而无需外接复用器或 PSI 发生器。
