Problems solved by technology

At present, this technology is still under research. The use of this technology solves the problem of bandwidth limitation to a certain extent, but it also raises new problems, such as how to adjust each link under the limited bandwidth allocated by each operator. The data transmission rate above, so that the data can reach the server at the fastest speed, and at the same time, the reliability of data packet transmission and other issues should also be considered

Embodiment Construction

[0053] The present invention is applicable to the scene of real-time multimedia data transmission. For example, the data source S needs to send the collected real-time multimedia data to the destination server D. Using the method proposed in the present invention, the data source S first establishes connections with networks belonging to different operators, and sends the data to each server D in a segmented manner. The relay server in the network, and then the relay server sends it to the destination server through the network edge router through a dedicated line.

[0054] The networks belonging to different operators may be of the same type or of different types. Taking three networks as examples, they may all be Wi-Fi TM , Wi-MAX TM wireless network or mobile network such as CDMA, GSM, or one of the networks is Wi-Fi TM network, while the other two networks are CDMA networks, or the three networks are GSM network, CDMA network, Wi-MAX TM The internet.

Abstract

The invention relates to a multi-link concurrent access multimedia data transmission method. The present method that using a single operator to provide transmission bandwidth can not support the high quality and real time transmission of multimedia service. The invention provides a multi-link concurrent access multimedia data transmission method which includes the server information acquisition, the segmentation of the data to be transmitted, the data transmission, and priority distinguished data transmission and data protection. Wherein, the data transmission includes an alternative test cycle and a data cycle; in the test cycle, the transmitting equipment test the performance of the data transmission link and the access link; in the data cycle, the transmitting equipment transmits data at each link according to the test result of the test cycle, thereby making full use of the link bandwidth resource and avoiding the link congestion. The multi-link concurrent access multimedia data transmission method of the invention adopts the transmission type by distinguishing the priority of different data at different priority; thereby ensure the transmission reliability of the high priority data.

Description

technical field [0001] The invention belongs to the field of multimedia data transmission, and relates to a method for transmitting multimedia data to a server with real-time requirements, specifically a method for simultaneously accessing multiple wireless networks, and transmitting the collected multimedia data to a server in real time in a concurrent manner. A high-speed data transmission method for a multimedia service server. Background technique [0002] The continuous improvement of network transmission speed enables the realization of real-time multimedia services. For example, some reporters transmit the data of on-site interviews to the server providing multimedia services in real time through the wired network, so users can watch the latest on-site reports at the first time by accessing the multimedia service server. . Real-time transmission of multimedia data to the server is the basic prerequisite for users to enjoy real-time services. However, due to the limit...
