METHOD AND APPARATUS FOR RATE CONTROL ACCURACY IN VIDEO ENCODING AND DECODING
摘要:
Methods and apparatus are provided for rate control accuracy in video encoding and decoding. An apparatus includes a video encoder for encoding image data using rate control. The rate control involves estimating a quantization step size and adjusting a rounding offset. The rounding offset is capable of being non-constant during the encoding.
