摘要
IPTV的业务形式分为视频播放类基本业务和增值应用类扩展业务,扩展业务由IPTV扩展业务平台来集中提供和管理。Web已成为最普遍的信息交互媒介,基于Web的具有丰富交互体验和快速响应能力的RIA正日益风行。本文提出了IPTV增值业务由客户端形式向服务端RIA形式演进的建议,并研究了适于部署这种新型服务端形式增值业务的基于WebOS集成中间件的IPTV扩展业务平台体系结构。
RIA （rich Internet application）becomes more and more popular now, and RIA-based value-added service for IPTV is suggested for its rapid response, good interaction, easy development and deployment in this paper. Furthermore, architecture of a new IPTV extended service platform based on WehOS middleware was discussed, which is excellent in supporting IPTV RIA-based value-added service.
