Description

Video-on-demand asynchronous interaction method under cloud architecture environment

technical field

The invention belongs to the technical field of multimedia, and relates to an asynchronous interaction method for video on demand under a cloud architecture environment.

Background technique

Video on demand means that according to the requirements of the audience, the video on demand system that plays the program transmits the video content clicked or selected by the user to the requested user. That is, the corresponding video programs are played according to the user's needs, which fundamentally changes the shortcomings of the user's passive watching TV in the past. There are three mainstream video-on-demand systems: 1) NVOD, which can be called quasi-video-on-demand. Its method is: multiple video streams start sending the same content at regular intervals, and one video stream can be shared by multiple users. 2) TVOD, which can be called real video on demand, its method is: when a user makes a request, the video server will immediately transmit the video content that the user wants, if another user puts forward the same demand, the video server will immediately serve him Start another video stream with the same content. 3) IVOD, called interactive video on demand. It can not only support point-and-play, but also allow users to interactively control the video stream, realizing program play, pause, rewind, fast forward and automatic search.

In the existing video-on-demand system, viewers can only watch video resources passively, but cannot interact with other viewers. This invention comprehensively considers the viewers and the server providing video under the cloud architecture, and proposes a cloud architecture Method for asynchronous interaction of video on demand environment. After a novelty search, the applicant retrieved the following two patents related to the present invention, which belong to video interaction, and they are:

1. Video interaction method and system (application number: 201110041977.4)

2. A cloud-based audio and video interactive scheduling method and system (application number: 201110238519.X)

In Patent 1, the inventor proposed a method for a single mobile terminal to perform real-time video interaction with multiple mobile terminals through a relay server.

Step1: The viewer records the feedback video file and uploads it to the server under the cloud architecture;

Step2: The viewer submits the playback time of the current video to the server under the cloud architecture;

Step3: The server under the cloud architecture receives the feedback video file uploaded by the viewer and the playback time of the current video file;

Step4: The server under the cloud architecture stores the feedback video file in the server, and records the storage path of the feedback video file;

Step5: Use the video playback time point as the keyword, and insert the storage path of the feedback video file into the mapping table. The mapping table is stored in the database in the order of the keyword dictionary. If there are the same keywords in the database, add to the table of contents for the same keyword.

The server under the cloud architecture looks up whether there is a feedback video file at this time point in the mapping table according to the current playback time point, including the following steps:

Step1: The server under the cloud architecture obtains the playback time of the current video;

Step2: The server under the cloud architecture queries the database whether there is an item whose key is the current playback time point;

Step3: If the match is successful, return the content of the item with the current playback time point as the keyword, and the server will display the feedback video file resource matching the current playback time point on the VOD page according to the storage path of the feedback video file; if it matches If it is unsuccessful, it will return empty, and the VOD page will not display any feedback video file resources.

The viewer chooses whether to play the feedback video file synchronously according to different on-demand methods, and the on-demand methods include the following two types:

1) Pause the current video, and open a feedback video file resource selected by the viewer in a new window;

2) In the current on-demand page, one or more feedback video file resources selected by the viewer are played synchronously.

The viewer chooses whether to play the feedback video file synchronously according to different on-demand methods. The specific steps are as follows:

Step1: When the viewer watches the video, the server under the cloud architecture displays the feedback video file resources related to the current playback time point in real time on the video-on-demand page;

Step2: The viewer selects the feedback video file they want to watch;

Step3: The viewer chooses the on-demand mode;

Step4: The server under the cloud architecture decides to open the feedback video file in a new window or play the feedback video file synchronously under the current page according to the on-demand mode selected by the viewer.

Compared with the prior art, the present invention has the advantages that video viewers can interact asynchronously at different times and in different places without being restricted by traditional video-on-demand, only passively watching videos, or having to be in the same Real-time interaction within a time period increases the flexibility of interaction.
