Embodiment Construction

[0027] The features, nature and advantages of the present invention will become more apparent after the following description in conjunction with the accompanying drawings and embodiments.

[0028] Firstly, a structural diagram of a specific embodiment according to the design scheme of the present invention will be described with reference to FIG. 1 . The present invention requires that, as in the scheme disclosed in CN 1127265, within a certain frequency band, the program information of multiple columns is compressed and played repeatedly and intermittently. Signals can be provided to multiple on-demand servers at the next level; the last-level on-demand server is connected to user terminals, and one last-level on-demand server is connected to multiple user terminals.

[0029] Refer to the structure of the existing cable TV network, which is also in the form of classification. Taking the cable TV network in Shanghai as an example, it includes a municipal-level broadcast cente...

Abstract

The invention includes multi levels program ordering servers. One of next higher level ordering server can provide signal to multi ordering servers in next lower level. The lowest level ordering server is connected with multi client-side terminals. The ordering method includes following steps: offering index information; receiving program ordering information from user terminal; looks up and finds the ordered content in each level ordering servers; renews program list; ends display and renews list. The invention can compress program in multi columns, and make repeating and intermittence display.

Description

technical field [0001] The invention relates to a method and a system for ordering on the network, in particular to an ordering method and system for a cable TV network. Background technique [0002] In the cable TV network, the demand for video on demand will be more and more. In reality, the biggest bottleneck in implementing video-on-demand in a wired network is that when the number of video-on-demand users exceeds a certain amount, the network bandwidth will be congested. Therefore, the video-on-demand service cannot be widely promoted in practical applications. [0003] The current direction of TV network development is to achieve real two-way on-demand. If the amount of programs in the future will become larger and tend to be "massive", using the current cable network will not be able to achieve two-way on-demand. In the known technology, Chinese Patent Publication No. CN 1127265, mentioned in the patent titled "Digital Compression Broadcasting Method and Receiving M...
