    摘要: A video encoding apparatus and method using a pipeline technique with a variable time slot are provided. More particularly, a video encoding apparatus and method capable of shortening a video encoding time by variably adjusting lengths of time slots when an H.264 video encoding process is performed in a pipeline structure are provided. The video encoding apparatus includes a plurality of functional blocks that perform video encoding steps based on an H.264 standard for macroblocks configuring input digital video signals in a pipeline structure, and a controller that controls lengths of time slots configuring the pipeline structure based on done signals received from the plurality of functional blocks. Lengths of time slots can be adjusted according to operation times of video encoding steps using done signals generated from functional blocks, thereby preventing unnecessary power consumption and delays when using a fixed-length time slot.
