Remote controlled electronic volume controller

摘要

An electronic volume device of an invention includes a common volume I/O (371) for receiving an i-th common volume level DcomÄiÜ (i = 1 to N) on a common scale of N steps, a volume converter (373) for converting the DcomÄiÜ into a j-th unique volume level Dvol ÄjÜ on a unique scale of n steps; and a volume controller (372) for controlling an electronic volume based on the unique volume. The volume converter (373) includes a volume memory for storing an offset between the DcomÄiÜ and the Dvol ÄjÜ and a volume controller that controls at least one of the Dvol ÄjÜ and the offset such that the received Dcom agrees with the sum of the Dvol ÄjÜ and the offset and controls the Dvol ÄjÜ on a higher priority than the offset. <IMAGE>
