Abstract: The present invention discloses methods and systems of statistical video multiplexing to improve the performance of video encoding by minimizing delay while achieving high video quality. The video encoders used in the system are capable of calculating the complexity of underlying video sources and communicating the complexity to the multiplexer. Furthermore, the video encoders are capable of estimating the look-ahead complexity, i.e. the future complexity and communicating the future complexity values to the multiplexer. A processor associated with the multiplexer allocates bit rates for the video encoders according to the received complexity values and future complexity values. The bit rate information is then communicated to the video encoders. Each video encoder will then exercise its coding control parameters to regulate the resulting bit rate to be within or close to the allocated bit rate.

Abstract: A handheld input device that comprises a touchpad having at least partly transparent panel with front and back sides which respectively face a front space and a back space, front and back touch sensing surfaces formed respectively at the front and back sides to detect a plurality of front touch events and a plurality of back touch events respectively on the front and back sides, and at least one back illumination source, mounted in the handheld device to illuminate fingertips facing the back touch sensing surface at the back space.

Abstract: A hand-held input/control device designed and configured such that, when it is held by a user oriented with its operating surface facing away from the user, the user may view the operation of the manually operable control members deployed on that operating surface.
