摘　　要：部队驻地大多远离城市,甚至在远离大陆的偏远海岛。针对这样的用户设计的小型化数字有线电视前端具有高集成度、高性能、低功耗、易维护的特点,已成功应用于西沙永兴岛。该前端在系统设计时采用了多种提高集成度的技术手段,使整个系统体积大大缩小,仅用1个机柜就实现了一个数字有线电视台的基本功能。In our country, many troops are stationed far away from cities, even in remote islands far from the mainland . The miniaturized Digital TV head-end designed for these users has the characteristics of high integration, high performance, low power consumption, easy maintenance, and it has been successfully applied in the Xisha Islands. The Digital TV head-end uses a variety of technical means of up integration in the system design, with which the whole system volume is greatly reduced, and with only one cabinet the basic function of a Digital TV station can be realized.
