Abstract

The invention provides a mobile video smooth-switching method based on a repeater station and relates to a video transmitting technology of a mobile internet; the method solves the problems that a mobile device is switched among different wireless network coverage areas, and the video transmission is not interrupted and is smooth in the address changing process of network layers; the main technical characteristics are that: a gateway of the mobile internet or a node directly connected with the gateway is used as a transmitting node for buffering and transmitting the video, smooth switching ofthe mobile video is realized by the operations of probability detection of the mobile device switching, video storage of the transmitting node, starting and switching detection, video transmission, rebuilding video connection of the mobile device, and closing the video transmission; the mobile video smooth-switching method can be used for video application of the mobile internet such as mobile video on demand, mobile video conferences, mobile TV and the like.

Description

technical field [0001] The invention relates to a mobile Internet video transmission technology, which belongs to the technical field of computer network, communication network, mobile communication and multimedia communication, and is especially suitable for mobile Internet, third-generation mobile communication network, and fourth-generation mobile communication network. Video delivery technology. Background technique [0002] With the development of Internet service quality assurance technology and Internet multimedia application technology, Internet video transmission and application technology have developed rapidly, and video applications on the Internet have gradually become a mainstream application. Internet television (IPTV), Internet video-on-demand, and network video interactive conferences have been widely popularized. [0003] With the development of mobile Internet technology and third-generation mobile communication (3G) technology and the popularization of a...
