摘要

尽管在提供数字视像和其他宽带DTH服务方面有延迟，但目前正在部署新的高容量卫星网络。本文介绍了一种为54 MHz宽Ku波段卫星传输系统开发的数字机顶盒，采用相干QPSK解调，总比特率为90 Mbps，总数据速率为54 Mbps，每个卫星转发器能够提供8个高质量的视频音频节目，并具有EPG(电子节目指南)等附加数据服务。低速(高达38.4 Kbps)异步数据和MPEG2 PSI(节目特定信息)和DVB SI(数字视频广播系统信息)数据表。

Consumer MPEG2 multimedia digital satellite receiver

In spite of the delays in availability of digital video and other broadband DTH services, new and high capacity satellite networks are currently under deployment. This paper presents a digital set-top box developed for 54 MHz wide Ku band satellite delivery systems with coherent QPSK demodulation with a total bit rate of 90 Mbps and aggregate data rate of 54 Mbps which is able to provide 8 high quality video-audio programs per satellite transponder with additional data services like EPG (Electronic Program Guide), low speed (up to 38.4 Kbps) asynchronous data and MPEG2 PSI (Program Specific Information) and DVB SI (Digital Video Broadcasting System Information) data tables.
