Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like figure 1 and figure 2 As shown, the invention of this application technology captures the real-time program information arranged linearly by program time, connects the program management of the content directory tree structure and the vertical time linear program management through dynamic data links, and expands the application field of VOD. Make audio and video assets have both content directory attributes and time linear attributes, maximize the utilization rate, improve user interaction experience, and freely switch between broadcast-style passive reception and supermarket-style active selection of audio and video modes to meet the needs of different user groups Usage requirements. First define some names:

[0031] Continuous broadcast: VOD on-demand program arranged linearly in time

[0032] Ordinary on-demand: traditional...

Abstract

The invention discloses a video on demand method and a video system. The video on demand method comprises the following steps of: transmitting a media asset file of a content production system to a broadcast server of a continuous broadcast system, wherein the continuous broadcast system is a video on demand system which is arranged in a time way; adding a unique asset identifier ContentID into the media asset file, generating a grogram list which is arranged via to time line according to the name, duration and asset identifier ContentID of the media asset file, and correlating the program list arranged via the time line with a corresponding media asset file, wherein the asset identifier ContentID is a description field in a service operation management system; introducing the program list which is arranged via the time line into the service operation management system, and releasing and presenting to the outside; and when a user accesses, making the service operation management system respond correspondingly according to the description field. According to the system and the method, real-time program information of which the program time is arranged linearly is captured, and program management of a contents directory tree structure is correlated to longitudinal time linear program management through dynamic data chaining, so that the user requirements of different user groups are met.

Description

technical field [0001] The invention relates to the field of digital television broadcasting, in particular to a video-on-demand system and method. Background technique [0002] VOD (Video on Demand) system is based on a two-way network and provides users with video on demand services. Compared with the broadcasting of traditional TV channels, VOD is more personalized, easier to operate, and has more diverse choices. When there are more program choices, the management, arrangement and presentation of programs become more and more important. [0003] The currently widely used VOD program management mode is that program assets are classified according to content attributes, arranged in a directory tree structure, and presented online to users for selection. However, such a program management presentation mode also has the disadvantage of ambiguous directivity, which weakens VOD's guiding function for users. Contents of the invention [0004] Aiming at the above-mentioned ...
