| 摘 要： | 随着电视节目的增加,数字移动接收已成为可能。而架设新的天线对已有的满负荷运行发射塔来说不是一件易事。用双工器将模拟电视与数字电视共用一副天线发射时也存在一些问题。本文就CMMB手持电视与模拟电视发射共用天线问题进行探讨。

| Abstract: | Currently,with the increase of TV programs,digital mobile reception is possible. It is difficult to set up a new antenna for transmission tower which is at full capacity. There are also some problems with analog TV and digital TV that share an antenna by a diplexer. The paper discusses the problems about the community antenna of CMMB hand-held TV and analog TV. |
