Abstract
A rate control method for multi-layered video coding, a video encoding apparatus and a video signal processing system employing the rate control method. In the rate control method for multi-layered video coding, encoding statistical information is generated based on the result of encoding input video data on a first layer. A second rate controller generates a plurality of quantization parameters to be used when encoding is performed on a second layer, based on the encoding statistical information and/or region of interest (ROI) information. Target numbers of bits that are to be respectively assigned to regions of a second layer are determined based on the encoding statistical information and/or ROI information, and the input video data is encoded at the second layer, based on the target numbers of bits.
