Video on demand method and system

Abstract

The invention discloses a video-on-demand method, which includes: the video-on-demand center divides the entire video-on-demand network into several small network nodes, and each network node corresponds to a unique number, which can be used as a service group information, and identifies the sending end information and service group information to establish a corresponding relationship, the user end sends an on-demand short message to the video-on-demand center, the on-demand short message includes the sender identification information and video-on-demand information, and the video-on-demand center finds the The service group information corresponding to the information, and the video program corresponding to the video-on-demand information is sent to the client through the network node corresponding to the service group information. The invention also discloses a video-on-demand system and another video-on-demand method. The invention can reduce the amount of data that the user needs to input in order information, and can prevent the user from being adversely affected by errors in the order information.

Description

technical field [0001] The invention relates to the field of video-on-demand, in particular to a video-on-demand method and system. Background technique [0002] Video on Demand (VOD, Video On Demand) means that users send video on demand information to the video on demand center through the network, telephone, SMS, etc., and the video on demand center sends corresponding video programs to the user receiving end according to the content of the video on demand information. You can watch your favorite video programs at the receiving end. [0003] Among them, the use of short messages for video-on-demand is not limited by time and region, which can be more convenient for users to use. see figure 1 , which is a flow chart of video on demand using SMS, the specific steps are as follows: [0004] Step 101, the user selects his / her favorite video program; [0005] Step 102, the user transmits user information, service group information, and video program information to the vide...

Problems solved by technology

However, because the interaction method of short messages is relatively simple, and the amount of information that can be transmitted by short messages is very small, there is generally no way to systematically consider the design of short message formats.

However, for VOD business, it is necessary to send a lot of information through short messages at one time, such as user information, service group information, video program information, etc. These information are all in the form of numbers or letters, which is very troublesome to input and extremely error-prone. , users and VOD centers are difficult to find, which may cause unnecessary trouble

[0008] For example, the digital number of the user's user group is 12538, but the user enters the user group number as 13538 due to negligence when inputting, if the user group 13538 does not exist, the VOD center returns a wrong message, and the user only needs to re-enter and send again; If the user group 13538 exists, the video-on-demand center will send the video program requested by the user to the network node where the user group 13538 is located, so that the user cannot receive the video program requested by himself, resulting in financial losses and losses for the user. waste of network resources

[0009] Text messages need to be encoded, sent, and decoded during sending. In this process, the original meaning may be changed due to abnormal reasons, which may cause ambiguity in the understanding of the video-on-demand center, and thus make wrong judgments, which will also cause unnecessary losses to users.
