Abstract

The embodiment of the invention discloses a digital television middleware-based video-on-demand method and system. The video-on-demand method mainly comprises the following steps of: initiating a video-on-demand request to a management server by utilizing a set-top box according to coding of a remote controller; initiating a video playing request to a video server by utilizing the management server; creating an on-demand flow and returning data to the management server by utilizing the video server, wherein the data content comprises related information such as a server IP (Internet Protocol) address, a port and flow control word information, IPQAM (Internet Protocol-Quadrature Amplitude Modulation) frequency point information, port information and the like; sending the server IP address, port and flow control word information and the IPQAM frequency point information and port information to the set-top box by utilizing the management server; and after the information is received by the set-top box, creating an LSCP (Lightweight Stream Control Protocol) link with the video server to decode and play. Through the video-on-demand method and system which are provided by the embodiment of the invention, the delay problem in NVOD (Near Video on Demand) is solved and the real on-demand effect is realized to ensure that a person can select favorite movies and other programs from a network at any time and immediately play.
