video coding complexity in the frame, intra-frame buffer level and the use of location-based buffer rate control

摘要

in the video encoding bit rate of the sequence of frames comprises a series of inter-frame are separated by an intraframe An apparatus and method for controlling, the coded frames are identified in the video buffering device before the transmission of the coded frames (validated), the method comprising: measuring the frame complexity of the sequence of frames, each of the interframe in contrast, the distance between the inter frame and then in relation to the interval between the intra-frame to calculate a target buffer level in said video buffer unit (calculating) step, for each inter frame, the inter-frame and the next intra-frame with respect to the target frame size to control a bit rate in the video encoding of the measured frame complexity, the current buffer in the video buffering device level and the sequence of steps for calculating the frame and the calculated target buffer level of the video buffer device to include the step of using the calculated target frame size. ; video coding, frames, a buffer, a bit rate
