Video information transmission method

Abstract

The invention discloses a video-on-demand (VOD) information stepped transmitting method. When packaging and compressing video, audio and text information, a VOD server respectively packages and compresses video information, audio information and text information in each time unit segment in the playing sequence, where the packages in the same time unit segment have the same time mark and are respectively transmitted in the priority of: text package, audio package and video package, and when an on-demand terminal receives the above packages, the packages with the same time mark are decompressed and synthesized to be played on the on-demand terminal. Thus, an online VOD system has higher intelligent processing ability, and can achieve better on-demand effect on the condition that various servers and network bandwidth resources are not stable, especially applied to cellphone's streaming media.

Description

technical field [0001] The invention relates to the field of network transmission of video information, in particular to a method for optimizing and processing video-on-demand information under the condition that server resources are tight and network communication conditions are unstable. Background technique [0002] Nowadays, the information network has spread to every corner of the society, and network technology has been closely related to our work and life. Through more and more developed network technology, we can easily exchange files, voice and text chat with anyone anywhere. Human needs and technological progress always complement each other. With the development of broadband network technology, the technology of obtaining text and voice information through the network has become increasingly mature. Obtaining video information through the network has become the general trend, and video on demand is a very important form. . However, video-on-demand takes up more s...

Problems solved by technology

However, in the current various video compression algorithms and transmission technologies, the video, audio and text information packets of the same playback time unit segment are processed and transmitted together. Although the processing process is relatively simple, the existing problems are: For the three types of information, audio and text, the occupation rate of server and network bandwidth resources is from large to small, and the difference in resource occupation is very obvious, that is, the resource occupation rate of video information is much greater than that of audio information, while audio information Information occupies much more resources than text information, but for users who watch video on demand, its importance is opposite. When the network environment is not good and users make choices, users have the highest requirement for the accuracy of text information dissemination Basically, it is required that the transmission of text information must be accurate, followed by audio information, and it is enough to hear clearly. For video information, it is acceptable to discard some data
