Abstract: Systems, methods, and apparatuses are provided for concealing errors in video data. It is detected whether a slice group in a picture contains errors. When the slice group contains errors and the picture is not a first intra-picture following a channel change, the slice group in the picture is replaced with a slice group of a most recent intra-coded picture. When the slice group contains errors and the picture is the first intra-picture following the channel change, the slice group is replaced with black pixels.

Abstract: A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.

Abstract: Schemes for rewinding a HITS stream in video recorder and playback systems are presented herein. Reference pictures are stored for a group of pictures, allowing subsequent pictures to be decoded from the reference pictures. The foregoing significantly reduces the number of picture decodes required to display a HITS stream in reverse order.

Abstract: A matrix converter includes a plurality of switches that electrically connect a multi-phase input voltage source to a multi-phase load; and a controller to output pulse-width modulated (PWM) switching signals to control the switches to produce a multi-phase output voltage from the multi-phase input voltage source. The controller outputs the PWM switching signals by modulating a carrier signal with a time-varying signal having a frequency determined from a desired output frequency for the output voltage.
