The number of battery cells connected together in a main battery conductor path of a multiple cell battery system of an information handling system may be varied in real time based on one or more operating conditions (e.g., system load power consumption, battery cell failure, etc.) of the information handling system. Defective battery cells may be bypassed such that the defective battery system may continue to operate and power an information handling system at a lower voltage, e.g., either temporarily, permanently or temporarily until the user procures a suitable replacement battery system. Interconnection of cells of a non-defective multiple cell battery system may also be selectively re-arranged to vary battery system voltage at particular times or during particular information handling system operation modes.

A method and system for deinterlacing an interlaced video stream is presented. The method and system determines whether an interlaced video stream is a normal mode video stream or a special mode video stream. Special mode video streams, which interlaced video streams created from a progressive original video stream, are deinterlaced using special mode deinterlacing, which involves merging two fields to form a frame. Normal mode video streams are deinterlaced using normal mode deinterlacing, which involves converting a field into a frame using line repeating or some form of interpolation to generate the missing scan lines.
