对于具有CMMB模块的移动终端要求当前端发送紧急广播时,支持CMMB的终端应能强行切换紧急广播,这要求移动终端必须对紧急广播系统有很好的支持能力,但是在现网环境条件下极少会发送紧急广播,这就给现网条件下测试手机电视的紧急广播功能带来了极大的困难。本文针对这一难题给出了一种行之有效的解决办法。
For a mobile terminal with a CMMB module to request that the current terminal send an emergency broadcast, the terminal supporting the CMMB should be able to forcibly switch the emergency broadcast. This requires that the mobile terminal must have good supportive capability for the emergency broadcast system. However, in the current network environment, Few will send emergency broadcasts, which will bring great difficulties to the emergency broadcast function of testing mobile TV under the current network conditions. This article gives an effective solution to this problem.
