“5.12”汶川大地震后,迅速恢复的信息通讯,让灾区群众及时、准确地了解到来自外界的信息.并成为确保灾区安定和救灾、重建工作顺利进行的重要条件。在有线广播电视网络遭受重创的情况下,广播电台和地面数字电视广播系统发挥了极其重要的作用。 After the May 12 earthquake in Wenchuan, the rapidly restored information and communication made the people in the disaster-stricken areas timely and accurately understand the information from the outside world and became an important condition for ensuring the smooth progress of stability, disaster relief and reconstruction in the disaster-hit areas. Radio and terrestrial digital television broadcasting systems have played an extremely important role in the wake of the cable television networks’ devastation.
