Problems solved by technology
However, the situation of mobile user terminals is seldom considered, such as different display resolutions of user terminals, different networks of users, and videos of different qualities with the same name on the server. Many factors will affect the quality of video-on-demand for mobile users.
For example, when a user orders a high-definition video, the display resolution of the user terminal is very low. Not only does the user not have the high-definition experience of the video, but the high-definition video may occupy a large amount of bandwidth, resulting in the terminal video not being able to watch smoothly.

Embodiment Construction
[0025] Relevant technical content and detailed description of the present invention, cooperate accompanying drawing to illustrate as follows:
[0026] The system mainly includes four parts: mobile terminal query interface, video server query system, mobile operator data query system, server on-demand system. like figure 1 shown. The mobile terminal query interface provides a user input and output interface; the user inputs a video-on-demand name and sends a viewing request, and the video query interface outputs video information corresponding to the video name or prompts the user that the video name does not exist, and obtains the user's terminal ID at the same time;
[0027] The video server query system queries the video of the specific name input by the user in the video server, and returns corresponding video information to the query interface of the mobile terminal;
[0028] The mobile operator data query system queries the mobile terminal's screen display resolution an...

The invention provides video on demand system and method based on a mobile user terminal. The video on demand method comprises the following steps of: firstly, sending a watching request and a video name by a user to the on demand system through a phone terminal, and synchronously acquiring a terminal ID (Identity) of the user; secondly, querying a video demanded by the user from a server by the system to acquire corresponding name and type of the video; thirdly, querying a mobile operator database by the system to acquire user terminal information; and fourthly, returning the video suitable for the user by the system according to the user terminal and the on demand video information, and providing online watching for the user by the server. The invention has the advantages of providing the video information suitable for user watching according to the conditions of different mobile user terminals, not only being capable of providing video on demand services with high quality for the user, but also effectively saving bandwidths and providing the services for more users at the same time.
Description
technical field [0001] The invention belongs to the field of mobile Internet, and mainly relates to providing videos suitable for users to watch according to the display resolution of mobile user terminals and network conditions. Background technique [0002] A video-on-demand service is a commonly used network service. In the mobile Internet, some ordinary network video-on-demand technologies are still used at present, and the service quality of mobile Internet users is not high, and the user terminal experience is poor. [0003] The main reason is that the existing video-on-demand system mainly considers optimizing the service quality of the server, such as video quantity, video size, network bandwidth, and the number of people who support simultaneous video-on-demand. However, the situation of mobile user terminals is seldom considered, such as different display resolutions of user terminals, different networks of users, and videos of different qualities with the same n...
