ENCODING RATE CONTROLLER IN A VIDEO ENCODER FOR IMPROVING IMAGE QUALITY BY THE CONTROL OF A REAL-TIME VARIABLE BIT RATE, A VIDEO DATA TRANSMISSION SYSTEM HAVING THE SAME AND A METHOD THEREFOR TO IMPROVE DISPLAY IMAGE QUALITY

摘要

The invention discloses improved in real-time variable bit rate controls the code rate controller of video encoder of picture quality, video-frequency data transmission system and it includes method. If the property of code rate controller and video-frequency data transmission system, code rate, and be not necessarily based on coding result and define distortion and previous image and bit is distributed to the relationship of present image, then present image is different from previous image. Picture is unrestricted, is not suitable for a bit, according to the variation picture of quantization size, adapting to different characteristics in the case where not using added bit, and quantization size is arranged. Therefore, when the identical real-time variable bit rate control method encoded in video data is decoded to show on a monitor, there is the effect that display quality can be improved.
