Problems solved by technology
The existing solutions that can achieve higher transmission rates include: using advanced technology to increase the information transmission rate and minimizing auxiliary equipment (such as reducing relay stations), such as the application of optical fiber technology, electromagnetic wave transmission, etc., although these increase through physical means. The bandwidth of the communication line can increase the rate of information transmission, but the cost is higher
And because the increase in bandwidth is limited, reducing network congestion is also limited

Embodiment Construction
[0028] The network-based multimedia information optimization transmission method of the present invention is to carry out statistical analysis on the multimedia information in the network, obtain the distribution of data, and use the hidden algorithm, knapsack algorithm and transportation algorithm to hide part of the information in the image or sound and other objects for transmission. Concretely include the following steps (the flow chart is as follows figure 1 shown):
[0029] 1) Statistical analysis is carried out to the multimedia information in the network, according to the type of multimedia information, determine the carrier object that will be used for hiding information, calculate the information hiding amount (101) of each carrier object with hiding algorithm;
[0030] 2) Select the carrier objects whose information hiding amount is greater than the actual size of the smallest carrier object, and the sum of the information hiding amounts of these selected carrier o...

The invention discloses a multi-media information optimized transmission method based on a network, comprising the steps of: statistically analyzing multi-media information in the network to obtain distribution state of data; and hiding part of the information in an image or voice by a hiding algorithm, a knapsack algorithm and a transportation algorithm for transmitting. Compared with the prior art, the method provided by the invention adopts various algorithms to hide part of the information in the network in voice or image and the other substances can be used as carrier objects of the hidden information for transmitting, therefore, the multi-media data traffic in the network is reduced, and the data transmission speed can be effectively enhanced without adding other physical equipment. Because other physical equipment is not required so that the cost is low; and visual effect is not influenced when the hiding is recovered after the transmission by hiding.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a network-based multimedia information optimization transmission method. Background technique [0002] At present, there are many sources of information, such as radio, television, news agencies, publishers, governments and financial institutions, etc., as well as from industrial and commercial enterprises and individuals, and these information will increasingly use multimedia data such as images, texts and sounds. form to express. Multimedia technology realizes the integration of graphics, text and sound, and audio-visual integration, and develops towards the most natural way for human beings to accept and process information. By integrating image, sound and other information, it solves the friendliness of the human-machine interface and enables information technology to play an important role. Significant efficiency, and can provide information services to users in a way...
