摘要
论文研究了一种新颖的基于片上系统(SOC)的多通道接收平台。它可对来自地面、卫星和有线等媒体的多路数字电视节目同时解码,并把它们转换成模拟基带信号。论文还讨论了基于计算机控制模型的实现,特别是时间片分配算法。该研究为我国模拟电视向数字电视转换的过程中,实现模拟接收机对数字电视节目的接收问题提供了一个低成本方案。
In this paper a novel receiver platform based on system-on-chips for multi-channel DTV program/services is researched.It can decode several programs from different transmission media such as terrestrial,satellite and cable simultaneously and convert them to analogue baseband signals.The implementation of computer control model is also discussed especially for the allocation of time slice.This research provides a low-cost scheme for the analogue receiver to obtain digital television program/service.
