一、前言 对于广播电台外的节目制作和新闻中继等,为了从现场以无线传送节目素材,可采用现场拾取装置(Field Pick—up Unit,FPU)。随着近年来发送设备和传输方式数字化的进展,关于FPU数字化的问题也正在进行研讨。 特别是对马拉松和长距离接力赛跑等中继,为了从移动中继车传送素材,可采用800MHz频 I. INTRODUCTION For program production and news relay outside the broadcasting station, a Field Pick-up Unit (FPU) may be used to wirelessly transmit program material from the scene. With the progress of digitization of transmission equipment and transmission methods in recent years, the issue of digitization of FPU is also under discussion. Especially for marathons and relay relay long distance relay, in order to transfer material from the mobile relay car, you can use the 800MHz frequency
