Abstract: A web video phone swaps applications between a flash memory and a DRAM. The applications are encoded to execution codes by an application unit and stored in the flash memory. Upon power up, the web video phone displays on an LCD thereof a top level menu having a plurality of graphic icons each representing a specific one of the applications, and checks whether a user chooses one of the applications. If the user chooses one of the applications, it is checked whether the DRAM has another application being executed currently. If the DRAM has another application being executed currently, the application being executed currently is uploaded to the flash memory together with the data generated during execution of the application. Subsequently, the chosen application is downloaded from the flash memory to the DRAM and executed.

Abstract: An apparatus and method are provided for controlling the amount of image compression data which is to be encoded in an image compression system using a wavelet transform. The amount of data accumulated in a channel buffer is controlled by removing from the wavelet-transformed image data, data cells which contain a frequency band and having a spatial orientation to which human eyes are less sensitive. An estimation is made as to how much data will accumulate in the channel buffer, based on a cyclic integration of the rate at which data is input to the channel buffer. The estimation is compared to a set of predetermined thresholds to determine how much if any of the wavelet-transformed image data is to be removed. If the estimation indicates an overflow, data cells D23, D43, and D83 are removed from the wavelet-transformed image frame. After overflow has been avoided, only data cell D23 is removed. If the estimation indicates an underflow, no data cells are removed.
