摘要
IPTV作为三网融合的一种产物,以其技术上的独特优势赢得越来越多用户的认同和选用。由于IPTV业务与双向有线电视业务有一定的相似性,IPTV市场拓展受到成熟的有线电视市场制约,加上IPTV技术层面与监管政策层面的一些问题,IPTV的发展速度低于人们的预期。随着技术上的不断改进以及竞争环境的逐步改善,IPTV的发展进程将有所加快,IPTV将与有线电视、卫星电视、地面电视形成相互竞争、相互补充、相互促进的多频道传输新格局。
As the outcome of three networks conver gence, IPTV is becoming more popular because of its unique technical advantages. Sharing the similar business scope, the market promotion of IPTV is restricted by mature cable TV technology. The problems in regulation and rules also slow down its growth. With the technical innovation and the improvement of competition environment, IPTV is going to compete with cable TV, satellite TV and free-to-air TV, and form a new prospect of multi-channel transmission with mutual competition, mutual complementation and mutual promotion.
