Abstract
The overall aim of this paper is transmission of Moving Picture Expert Group (MPEG) video stream over a Bluetooth channel, using Transformation method. The MPEG Variable Bit Rate (VBR) data sources are Unpredictable and have substantial variations in bit rate, which could result in data loss and image quality degradation. A transformation method is introduced so that the controller may adjust itself to the current state of the system under control. A traffic-shaping buffer is used to prevent excessive back-to-back transmissions of MPEG VBR data sources. A rule-based fuzzy (RBF) controller regulates the average arrival rate to the traffic-shaping buffer to prevent either overflow or starvation of the buffer on a Group Of Picture (GOP) by GOP basis. The computer simulation results show that the use of the Transformation Control reduces excessive delay and data loss at the hostcontroller-interface, as compared with a conventional VBR video transmission and a rule-based fuzzy controller (RBF) in Bluetooth.
