摘　　要：目前，国内的移动通信行业已经正式立项开始综合研究470～698MHz频段的使用问题。在国内移动通信行业与广播电视行业的不断博弈与协作之下，融合型的视听内容传输平台或将成为长远的发展趋势之一。探讨了视听技术的四大发展趋势，并在此基础之上，探索这些传输方式对于地面无线接入网络（尤其是这两大类型的地面无线接入网络，即地面数字电视广播网络与无线移动宽带通信网络）的后续演进将会产生的影响，进一步地，提出分别从技术、成本与经济这3个角度考量融合型视听内容传输平台的思路。At present, the domestic mobile communications industry has officially started a comprehensive study of the use of fre- quency band 470 -698 MHz. In the domestic mobile communications industry and the radio and television industry continue to co- operate with the game, the integration of audio-visual content transmission platform or will become one of the long-term develop- ment trends. In this article, four development trends of audio-visual technology are discussed, and based on this, the impact of these transmission modes on the subsequent evolution of terrestrial wireless access networks is explored, especially these two types of terrestrial wireless access networks, namely terrestrial digital television broadcasting networks and wireless mobile broadband communication networks. Further, the idea of the integration of the visual content transmission platform from the three perspectives of technology, cost and economy are proposed respectively.
