Apparatus and method for controlling variable bit rate in real time |
摘要 |
An apparatus and method for controlling a variable bit rate in real time are provided, including an encoding unit for performing a predetermined image conversion on present video data to be encoded and for encoding the video data into a variable bit rate by quantizing the conversion result, and a variable bit rate controller for allocating an overall bit estimate of the video data to be stored in a system to each frame according to a variation in video recording time, for detecting the complexity of frames based on a difference between pixels of the encoded video data and for determining a quantization factor using the detected complexity.
