A mobile communication device and a data reception method implemented thereby are provided. In an implementation, each of a plurality of remote control devices is associated with a respective client device in an audio visual system. A second device includes a lever for moving the front edge of the panel in a vertical direction. A wheel is positioned in association with said frame and pedals configured to interact with the wheel, and the frame is configured to pivot about the first mounting point and second mounting point in response to leaning by the user. Then, in response to a received request that indicates a category, the CRS determines and provides indications of one or more content items that each have a corresponding category that matches the indicated category. Once a task declares its lack of a future need to access a shared data, the synchronizing logic allows that shared data to be accessed by other tasks that have indicated their need to access the same.
