输出传输 meaning in English

outgoing transmission

The focus is about the char device driver design used in the dvb receiving card and the drive development process in user space ; analyzing the dvb receiving system working principle and process under linux and providing a method to load the linux dvb receive card device drive into the linux kernel ; analyzing and implementing the firmware design of saa7146 chipset working with linux kernel and working characteristic in vrious working mode ; analyzing and implementing the frontend drive programing of the digital tv receive system ; realized the qam demodulation and the mpeg stream filter , so that the output stream can be used to playing on pc better . and this article designs an event management mechanism based on the mhp , which improve the linux dvb software system
重点研究了数字电视接收卡的字符设备驱动问题,阐述了用户空间开发驱动程序的过程;分析了linux下数字电视接收系统的工作原理和驱动程序开发过程,给出了linuxdvbapi接收卡设备驱动程序加载到linux内核中的方法;研究实现了saa7146芯片配合linux内核共同工作的固件设计和不同工作模式下的工作特性;研究实现了dvb接收系统中前端驱动程序的编写;设计实现了qam解调和mpeg流解复用,使输出传输流较好地用于pc播放;同时,本文所设计的一种符合mhp规范的中间件事件管理机制,优化了linuxdvb软件系统。
