Embodiment Construction
[0028] 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.
[0029] combine first figure 1 Describe the structural diagram of a specific embodiment according to the design scheme of the present invention. The present invention requires that the same as the disclosed scheme of CN1127265, in a certain frequency band, compress the program information of multiple columns, and play it repeatedly and intermittently. Signals are 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.
[0030] 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 center, multiple district-lev...

The invention discloses a system for realizing on-demand broadcasting in the network. Within a certain frequency band, the program information of multiple columns is compressed and played repeatedly and intermittently. The server can provide signals 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. The invention also discloses a method for implementing on-demand in the network, which includes providing index information; receiving on-demand information from user terminals; sequentially searching and playing the on-demand content in all levels of on-demand servers; updating the list of on-demand programs; update list. The scheme can realize two-way real-time video-on-demand with a large amount of data in the cable TV network, which is in line with the development direction of the TV network, but the premise is that it does not guarantee that all users can enjoy their on-demand content from the beginning.
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. CN1127265, mentioned in the patent titled "Digital Compression Broadcasting Method and Receiving Me...
