Abstract: This invention is a new communication system in which multichannel broadcast digital services are distributed to each user with the broadcast services signal riding in the passband above a digital baseband signal. The system can deliver more than 1 Gbps additional bandwidth to each subscriber. The passband bandwidth will accommodate growth in downstream services including video on demand, higher speed web downloads including improved streaming audio and video, HDTV, interactive video, and personalized video. The invention requires only a single fiber path and a single optical receiver for each user or group of users. A single fiber, single optical receiver system is much less expensive than two systems, one transmitting baseband and the other passband. A single receiver is greatly cost beneficial to achieving economical fiber to the home.

Abstract translation: 本发明是一种新的通信系统，其中多通道广播数字业务被分配给每个用户，广播业务信号在数字基带信号上方通过通带。 该系统可以为每个用户提供超过1 Gbps的附加带宽。 通带带宽将适应下游业务的增长，包括视频点播，更高速度的网络下载，包括改进的流式音频和视频，HDTV，交互式视频和个性化视频。 本发明对于每个用户或用户组仅需要单个光纤路径和单个光接收机。 单光纤单光接收机系统比两个系统便宜得多，一个发射基带和另一个通带。 单个接收器对于实现经济的光纤到家是非常有益的。
