Method for receiving video data and system for distributing video data

Abstract

The invention provides a method for receiving video data and a video data distributing system. The method is as follows: the receiving mode of receiving the video data is selected, wherein the receiving mode is the data broadcasting mode in which the video data circularly broadcasted on a front end of data broadcasting service by a video broadcasting network and the P2P mode in which the video data are acquired from a new media platform or a user terminal storing the video data by a wideband network; and, the video data are acquired by utilizing the selected receiving mode. When the user needs the video service, the video data can be acquired by receiving the broadcasting data; in addition, the video data can also be acquired from other users having the video data in the P2P mode, thereby overcoming the defects existing in prior art, meeting the needs of more users and providing high quality video service for users.

Description

technical field [0001] The invention relates to multimedia information communication technology, in particular to a method for receiving video data and a video data distribution system. Background technique [0002] At present, personalized and interactive video services are new economic growth points, but because video services consume a lot of bandwidth resources and server resources, especially programs in high-definition format, the system scale is limited. [0003] The existing video distribution system in the prior art is based on data broadcasting technology. For example, the invention patent application with the publication number CN1264976A and the title of the invention is a data broadcasting system for digital video broadcasting, which discloses a data broadcasting system, as shown in Figure 1 . In this system, the video content is pushed to the user end in the way that the service front end circulates a large amount of data at a high speed in a digital video bro...

Problems solved by technology

[0005] The method for users to receive digital video broadcasting is single; and the function of the video broadcasting system is single, which is not conducive to the development of large-scale video service business, and it is difficult to provide interactive video services; although the transmission capacity of data broadcasting is relatively large, the data transmission required For example, based on the data video broadcasting (DVB) transmission rate of 38Mbps, it takes at least 30 minutes for the user terminal to receive a set of 8G high-definition movies

Therefore, as the number of video programs requested by users increases, the amount of corresponding data increases, making it impossible for each user's service request to get a quick response, so that the time for users to wait for receiving data increases, which lacks flexibility.
