Abstract: The variable bitrate coding method according to the invention comprises an iterative process including a first coding pass and a second prediction pass. The coding pass allows for a picture coding of a sequence with a constant quantization stepsize (and quality) and the prediction pass allows for a matching of the stepsize to the wanted target bitrate. After some iterations, a last step allows for a finer adjustment of said stepsize with respect to said target bitrate.

Abstract: The variable bitrate coding method according to the invention comprises an iterative process including a first analysis pass and a second prediction pass. The analysis pass allows for a picture coding of a sequence with a constant quantization stepsize (and quality) and the prediction pass allows for a matching of the stepsize to the wanted target bitrate. After some iterations, a last step allows for a finer adjustment of said stepsize with respect to said target bitrate.

Abstract: The variable bitrate coding method according to the invention comprises an iterative process including a first analysis pass and a second prediction pass and followed by a last control step for adjusting said stepsize with respect to said target bitrate. According to the invention, a picture re-arrangement step is provided between the analysis and prediction steps of one iteration, in order to encode with an improved quality the picture sequence. Application: MPEG-2 encoders for storage media with limited capacity.

Abstract: An apparatus and method for enlargement of soft tissue, such as breast, including a vessel or dome configured to fit over the tissue which is to be enhanced or enlarged. The dome or vessel has a sealing cushion of elastic material which surrounds and encompasses the perimeter of the base of the vessel. The cushion includes a fluid compartment which is compressible. The fluid compartment is deformable such that when the vacuum is applied to the sphere, the seal material and compartment deform, isolate, and diffuse the pressure on the skin. The apparatus also includes a vacuum pump with a power source, a pressure sensor to regulate the pressure, or vacuum provided by the pump. The dome also includes a valve mechanism for controlling the ingress and egress of the vacuum to the interior of the dome. This valve will automatically close so that the pump may be removed from the dome and the pressure or vacuum therein be maintained.
