Embodiment Construction

[0031] The embodiment of the present invention provides an on-demand control method that comprehensively utilizes unicast technology and multicast / broadcast technology, realizes video-on-demand services that users watch on demand, and reduces the cost of servers and network bandwidth at the same time. application as an example.

[0032] The implementation principle of the embodiment of the present invention is shown in Figure 3, assuming that the nVOD server at the head end outputs n (n>=1) multicast channels of video programs, and on each multicast channel, the video programs are broadcast in the form of IP multicast After being sent to the network, each multicast channel plays a video program in a loop, and the start times of the n channels are sequentially staggered for a certain period of time. The network can be a metropolitan area network of a city, or a backbone network between cities, or can be directly linked without network equipment. The client device joins a certa...

Abstract

The related video order-control method based on monocast and MBMS comprises: when user orders video menu, it selective adds into the nearest MBMS channel to receive menu data even use monocast technology if necessary. This invention combines advantages of monocast and MBMS business, and reduces cost for server and network bandwidth.

Description

technical field [0001] The invention relates to media playing technology, in particular to a video-on-demand control method, a client device and a switching control device. Background technique [0002] The development of traditional analog TV to digital TV has laid a foundation for the flexible processing of TV programs, and various novel services have emerged one after another. The characteristics of the initial broadcast TV service are one-way (the user has no service interaction with the head end) and broadcast type (many users watch the same program). However, people's requirements are getting higher and higher. People hope to see the programs they want to watch, not necessarily the ones currently broadcast; See; people want to be able to fast-forward and rewind as they please, not necessarily from the beginning to the end. [0003] In order to meet this demand, a video on demand VOD (Video on Demand) technology has emerged. The implementation principle of VOD techno...
