A data bus bridge circuit and method are provided for coupling a slave device with a data bus in a system in which data words are transferred between a master device and the slave device over the data bus. Upon receipt, a set of tables are populated using data within the requests. The first decoding process and the second decoding process are appropriately switched according to each coded image signal. An image history is then accessed to obtain a last known good point in time image of the application. Objects containing certain elements or related elements may be associated to form an information group, to which information management policies may be applied as a group. At least one operational resource to perform a transformation of an audio information is estimated based at least in part on the obtaining the operational capacity.
