Abstract
A video encoder controlling rate of each frame in a current frame set (Group of Picture, GOP), and method thereof. The video encoder comprises a frame grouping device, a GOP initialization device, and a GOP encoding device. The frame grouping device allocates a target bit budget Rto the current frame set. The GOP initialization device is coupled to the frame grouping device, and estimates a first quantization parameter QPbased on the target bit budget Rand complexity of the current frame set. The GOP encoding device is coupled to the GOP initialization device, and encoding a frame in the current frame set with the second quantization parameter QPto generate output data.
