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.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a video-on-demand method and system based on digital TV middleware. Background technique [0002] With the overall translation of analog TV to digital TV and the two-way transformation of the network, the development model centered on digital TV has gradually become the most suitable way to realize the digital family in our country. In this development model, with digital TV middleware technology as a guarantee, users can also perform various forms of interactive value-added services when watching high-definition digital TV programs. As one of the value-added services of the broadcasting and TV industry, digital TV video on demand has fundamentally changed the viewing mode of traditional TV media, making watching TV no longer a passive demand, but a kind of autonomy of TV viewers choose. [0003] In the era of rapid development of middleware technology, multimedia technolo...
