Self-adaption video transmission system and method of cell terminal network

Abstract

The embodiment of the invention discloses a self-adaption video transmission system and method of a cell terminal network. The system comprises a first decoder, a first coder, a network state estimation module, a second decoder, a first buffer region and a second buffer region, wherein the first decoder is used for converting the format of a received analog video signal into a digital signal format; the first coder is used for coding a received high-definition digital video signal in an FGS (Fine Granular Scalability) manner; the network state estimation module is used for an estimation algorithm which is used for determining which frame dropping policy is adopted for the first buffer region according to relevant information, of network bandwidth, sent by the second buffer region; and the second decoder is used for decoding a video code stream provided by the second buffer region and converting the video code stream into digital television signals to be used by a home user. By implementing the invention, uniform video signal coding and smoother cell video signal transmission are realized, so that the problems that the user cannot watch the television and the like due to blockage of the video signals are avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a district-end network self-adaptive video transmission system and method. Background technique [0002] With the rise of the digital home informatization industry and the continuous attempts of different management development models, the mode of taking the community as the smallest management unit has been recognized by most people, and has become the development direction of digital home informatization in Guangdong. Therefore, the community is used as the unit object. Research and development of digital home technology is necessary. [0003] In modern digital life, video experience accounts for a large proportion of home entertainment, and all aspects of people are inseparable from the influence of visual effects. However, due to the limitations of hardware resources and transmission lines, it is not All TV users in the entire community can play high-definition video ...

AI Technical Summary

Problems solved by technology

[0004] Now the community is used to jointly manage the digital TV network and other signals of the community users. If too many users operate the network at the same time, some users will not be able to use functions such as video on demand, and even cause large-scale network congestion.
