A novel compression algorithm incorporating the near-best wavelet packet transform is introduced for multi-modal signals in low bitrate telemonitoring applications. The method permits flexible control of the total bitrate subject to the constraints of the channel, and the allocation of the total bitrate to each of the constituent modes subject to the quality preferences of the observer. Its performance is demonstrated using polysomnograms with 4 different signal modes (ECG, EEG, BP and NT)
