| 摘 要： | 探讨了有线电视网络DVB和DOCSIS协议在数据传输业务中的融合问题，提出了DVB视频和DOCSIS数据带内、带外两种混合传输技术，并在双向HFC网上实现了基于DOCSIS回传信道的视频点播系统。下行方向利用DVB-C发送视频节目，上行利用DOCSIS回传信道传送用户点播信息，实现交互。同时提出了基于DVB／DOCSIS带内融合技术的机顶盒设计方案。

| Abstract: | The convergence of DVB and DOCSIS protocols in data transmission over HFC network is discussed. Two techniques called in band and out band convergence of DVB and DOCSIS protocols in data transmission are proposed. Based on these techniques, two kinds of interactive VOD systems are established. DVB C protocol is used in the downstream, while DOCSIS protocol is used in the upstream to send user's requests. A new Set Top Box model based on the technique of DVB/DOCSIS in band convergence is also proposed. |
