A video conversion method for frame rate reduction. Video data comprising at least one I-frame and a plurality of B- and P-frames is provided. The B- and P-frames are converted to P-frames using a first image processing method, thereby leaving the I-frame and a plurality of P-frames. A frame rate reduction operation is implemented based on the converted frames using a second image processing method.

Video conversion methods for frame rate reduction

A computer housing includes a shell having a side opening, a first side wall and a second side wall, and a support bracket rotatably mounted on the shell and having a head portion, a tail portion, and a support portion. Thus, when the support bracket is rotatable to a closed position, the tail portion of the support bracket is rested on the second side wall of the shell, and the support portion of the support bracket is received in an inside of the shell, and when the support bracket is rotatable to an open position, the tail portion of the support bracket is detached from the second side wall of the shell, and the support portion of the support bracket is detached from the inside of the shell.

A transcoder system for adaptively reducing frame rate is provided, which can change audio-visual stream of a GOP (group of picture). Each picture in the GOP consists of a plurality of macroblocks. The transcoder system includes a switching device, a variable length decoder, a motion vector compensation device, a memory and an encoder/decoder. The motion vector compensation device can compute output motion vectors respectively for the macroblocks in accordance with input picture types, so video data of I-, P- and B-pictures without complete reduced frame-rate transcoding in the prior art can be avoided. Therefore, video transcoding for pictures can be performed completely and quickly to thus reduce required transcoding computation and further increase transcoding speed.
