Problems solved by technology

In order to reduce the bandwidth occupation, it is necessary to reduce the sending frequency of session messages. Since the RTT value is always changing, the measurement frequency is too low to make the measurement meaningless.
[0007] Therefore, the existing interactive multimedia transmission methods that currently exist are not very satisfactory in terms of robustness, reliability, and scalability, and cannot meet the needs of interactive multimedia applications on the market.

Abstract

A method for realizing interactive multimedia data transmission characterizes in containing steps of connecting characterizes in containing steps of connecting to new users to a tree-like structure in terms of self-organization, the steps of carrying out transmitting-receiving multimedia data according to data routing steps, the steps of quitting from the tree-like structure based on the self-repairing step then to dynamically regulate the tree-like structure.

Description

technical field [0001] The invention belongs to the technical field of multimedia network, in particular to a method for interactive multimedia data transmission. Background technique [0002] With the rapid development of network and multimedia technology, many interactive multimedia applications have emerged, such as teleconferencing systems, distance teaching systems, and online games. Thus, various types of multimedia data will be interactively transmitted on the network. However, the existing network is a very complicated situation. Users can either access the Internet through dial-up or access the network through a local area network. In this way, the bandwidth of user access varies greatly. For example, dial-up Internet access only has a bandwidth of 56K, while access through a LAN can have a bandwidth of 10M, 100M or more. Moreover, the performance of user terminals will also vary greatly. Users can be high-performance workstations, or handheld or embedded devices ...
