Embodiment Construction

[0033] In order to make the solution of the present invention more clear and complete, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Aiming at the problems of network congestion and server busyness caused by insufficient network bandwidth in the traditional technology when ordering digital TV programs, the present invention proposes a digital TV program ordering system and an ordering method; Obtain resources in a unified way for users within the area where the portal server is located to order. The user terminal records the user's browsing behavior. When the user needs to order, the recording result is sent to the portal server. The customary program list allows users to order the programs they are interested in. The scientific division of labor between the portal server and the user terminal greatly shortens the two-way interaction time, and because there is no direct interaction between each user...

Abstract

The invention relates to a digital television program on demand technology, and discloses a digital television program on demand method, which solves the problems of network congestion and server busyness caused by insufficient network bandwidth in digital television program on demand in the prior art. Key points of the technical scheme can be summarized as that: a way of realizing direct interaction between a user terminal and a front-end server for resource on demand in the prior art is abandoned; and a portal server uniformly acquires resources from the front-end server as an intermediate bridge, locally caches the acquired resources, and transmits a program list according to browsing habits of a user, and the user selects own favorite program for on demand according to the program list. In addition, the invention discloses a digital television program on demand system, which is applied to bidirectional network reconstruction.

Description

technical field [0001] The invention relates to digital television program on-demand technology, in particular to a digital television program on-demand system and an on-demand method. Background technique [0002] Traditional digital TV program playback adopts a one-way transmission mode, that is, the broadcast TV front-end server (hereinafter referred to as the front-end server) broadcasts digital TV programs through various frequency points, and the user receiving terminal (hereinafter referred to as the user terminal) passively receives the program, which will cause users There is no subjective selectivity for TV programs; with the development of digital TV networks, two-way networks are highly respected by users, and the front-end server and user terminals use two-way networks for two-way interaction, that is, users can order their favorite programs at any time. The user terminal can also record the user's resource on-demand status at any time and feed it back to the fr...
