Design and implementation of layer architecture software modules for LCD TV systems

Due to the need of compatibility between software and hardware modules of a LCD TV system, we propose a software design with layer architecture for a LCD TV system. With the layer architecture, we need only modify the device driver layer for the different chip sets and the user interface layer for the different operating systems. With this advantage we can shorten the product design cycle for the different chip sets by the reusing most of the previous software modules. To reduce the design complexity of the LCD TV system, we adopt the mechanism of the state/event matrix and message queue instead of the complicated state machine design to control the TV system operation.
