Abstract
In a multi-channel system, a transmitting encoder includes an adaptive quantizer for each channel, an adaptive bit-allocator operating common to all channels using an update algorithm, and a multiplexer which rearrange signals responsive to bit-allocation information which in turn is not transmitted. At the receiving decoder, bit-allocation information is recovered by logic using the transmitter update algorithm. Four embodiments are disclosed.
