Abstract
Abstract An efficient coding signal processor for encoding information signals input in a sequence of block units in a manner of unifying an amount of information at a unit of N frames (N / 1), which includes a block activity calculator (7, 7c) for calculating a block activity for every block of the information signals in a present frame, a frame activity calculator (20) for calculating a frame activity from the block activity of the block in the preceding frames, a code amount allocator (11, 11c) for allocating an amount of codes for every block in the encoding process using the predicted frame activity, and a code amount allocation controller (24, 24c) for controlling the amount of codes to be allocated for every block up to a preselected bit rate by monitoring the amount of codes allocated by the code amount allocator for the period of one frame. <IMAGE>
