Problems solved by technology

The number of users supported by this method is not limited, but a program occupies multiple channels / channels, and there are very few programs to choose from
[0005] Therefore, the current video-on-demand technology generally has the disadvantages of supporting few users or selecting on-demand programs, and there is still a long way to go to provide universal humanized services.

Embodiment Construction

[0024] The technical solution for realizing the object of the present invention comprises the following steps:

[0025] a. Store a large number of video program files in the storage server of the front-end system of cable or wireless TV;

[0026] b. Select some programs in the front-end system as the pre-broadcast content for a certain period of time to form a pre-broadcast program list. In addition, during the pre-broadcast process, some programs selected earlier can be removed from the pre-broadcast program list at any time, and new ones can be added. program;

[0027] c. The front-end system generates a pre-broadcast EPG according to the pre-broadcast program list at any time, and broadcasts to the TV network. The pre-broadcast EPG includes the following contents: program name, program introduction, duration, file size, , ..., ;

[0028] d. The digital TV set-top box that supports program pre-broadcast receives the pre-broadcast EPG, and provides the user with the name an...

Abstract

This invention provides a method for realizing large scale digital TV video selections on one-way TV network, in which, a front server sends TV programs to the TV network by digital broadcast, users use the set top boxes of TV to receive and select digital broadcast of the related TV programs, the selected programs are buffer-stored on the hard disks of the set top boxes to be provided to users. This invented method can support large quantity of users to select programs not necessary to reform circuits.

Description

1. Technical field [0001] The invention relates to a digital TV transmission and reception technology, in particular to a method for realizing large-scale digital TV video-on-demand on a one-way TV network. 2. Background technology [0002] The main way to watch video programs now is to receive cable, wireless or satellite broadcasts through TV, which has the advantages of wide coverage and unlimited number of supported users, but it has its own weaknesses, such as fleeting, only passive order watch. Therefore, video on demand has attracted people's attention. Video on demand allows users to easily select programs and start playing from anywhere. At present, there are video-on-demand solutions based on various technologies: [0003] Video-on-demand based on computer networks has been very mature after a long period of development, but due to the limitation of network bandwidth, the number of online video-on-demand users is limited. In order to increase the number of supp...
