A system for monitoring a patient and treating the malfunctioning heart of the patient, either in an automatic mode or in a semiautomatic mode, includes means which derive at least one physiologic signal from or related to the patient's circulatory system representative of hemodynamic status. A feedback loop is implemented in a biventricular implant, in order to automatically or selectively optimize the patient's clinical hemodynamic status. Accordingly, the biventricular implant will be programmed to go through a series of AV delay, RV-LV timing and heart rate sequences which scan a preselected range of programmable values and apply those values to the patient's heart. Hemodynamic patient measurements will be recorded and preferably graphed over those applied values. The optimal AV delay, RV-LV timing sequence and pacing rate can then be selected either manually by a technician, physician or other operator, or automatically via the implant in order to secure the best personalized timing sequence for the patient. Preferably, the implant will also be capable of automatically recording hemodynamic information and adjusting intervals, in order to optimize hemodynamics without third party intervention. Also preferably, the automatic adjusting feature can be selectively programmed on or off using the device programmer, to control manual or automatic intervention.

A video compression method and apparatus uses an active decoder. The corresponding encoder can produce an encoded bitstream with a greatly reduced overhead by encoding a reference frame based on the structural information inherent to the image (e.g., image segmentation, geometry, color, and / or brightness), and then predicting other frames relative to the structural information. Typically, the description of a predicted frame would include kinetic information (e.g., segment motion data and / or associated residues representing information in previously occluded areas and / or inexact matches and appearance of new information, and portion of the segment evolution that is not captured by motion per se, etc.). Because the decoder is capable of independently determining the structural information (and relationships thereamong) underlying the predicted frame, such information need not be explicitly transmitted to the decoder. Rather, the encoder need only send information that the encoder knows the decoder cannot determine on its own.

A decoder decodes compressed video data wherein nonkey frames are decoded with reference to other frames from the video data that are reference frames. The decoder generates at least a part of a segmentation of the reference frames for use in decoding nonkey frames. A nonkey frame is regenerated using kinetic information about the current frame and the reference frame segmentation. Kinetic information might include segment translation information. Where the segmentation used in encoding the compressed video data can vary among a plurality of segmentation schemes, the decoder determines which segmentation scheme is used from selection indications in the compressed video data or from previously decoded video data. The decoder might also use partial segmentation information, segmentation hints, partial segment canonical information and / or canonical hints in its segmentation process. The decoder might also process segment-related metadata extracted the compressed video data.
