基于网络的数字模拟混合电视接收系统的硬件设计与实现

介绍通过网络来播放数字电视和模拟电视的用户接收终端的解决方案。该方案基于Micronas的信道解调器和MPEG压缩编码芯片,可以支持NTSC、PAL、ATSC、QAM、DVB-T等模拟和数字多制式电视标准,以及Composite、S-Video、YPbPr等模拟视频信号,LR左右声道音频信号输入,通过以太网口或者PCI无线网卡与网络相连,将流媒体传输到网络上并由用户终端PC机解码播放。

Hardware Deign and Implementation of the Digital Analog TV Hybrid Network

This paper introduced settlement of the user terminals when the digital TV and the analog TV are broadcasted through the network.This settlement bases on the Micronas demodulator and MPEG encoder SOC chip Cypher7108 and supports the analog and digital multi-standards,such as NTSC,PAL,ATSC,QAM,DVB-T and so on,as well as the analog video signals as S-Video,YPbPr and the importing of the LR audio frequency.And through the Ethernet or PCI wireless network card,the streaming media can be uploaded and be played by the PC on the user-end.
