Approach to video transmission wireless technology

Video transmission over dynamic channels like 2.4 GHz wirelesstechnology is unpredictable, because of interferences caused by otherwireless devices in the same ISM (industrial, scientific and medicine) frequency band and/or general channel noises. Transmitting moving picture expert group (MPEG) video stream over wireless technology also presents a challenge, as MPEG demands large bandwidth. Considering these issues, an intelligent transmission is introduced in this research so that the controller may adjust itself to the current state of the wirelesschannel in order to sustain MPEG video quality during the communication process.

A neural-fuzzy controller and a rule-based fuzzy controller are implemented in the design to monitor input – output of a traffic shaping buffer and offer suitable parameters for the MPEG encoder for video transmission over the network. Matlab computer simulation results show that the proposed method reduces data loss and improves image quality as compared with traditional MPEG video transmission over 2.4 GHz wireless technology.
