摘要： A method and system for bit rate control during encoding of multimedia data are disclosed. A change in complexity of a multimedia picture relative to complexity associated with one or more multimedia pictures in a multimedia sequence is determined. A complexity associated with a multimedia picture is determined based on number of bits and an average quantization associated with the multimedia picture. A bit rate is adjusted for encoding the multimedia picture based on the change in complexity of the multimedia picture. The bit rate is increased on determining an increase in complexity of the multimedia picture and is decreased on determining a decrease in complexity of the multimedia picture. Utilization of additional bits during the increase in the bit rate and saving of bits during the decrease in the bit rate are compensated during adjusting of bit rates for encoding subsequent multimedia pictures in the multimedia sequence.

摘要翻译： 公开了一种用于多媒体数据编码期间比特率控制的方法和系统。 确定多媒体图像相对于与多媒体序列中的一个或多个多媒体图像相关的复杂度的复杂度的变化。 基于与多媒体图像相关联的比特数和平均量化来确定与多媒体图像相关联的复杂度。 基于多媒体图像的复杂度的变化，调整比特率以对多媒体图像进行编码。 在确定多媒体图像的复杂度的增加时，比特率增加，并且在确定多媒体图片的复杂度的降低时减少。 在调整用于对多媒体序列中的后续多媒体图像进行编码的比特率时，补偿比特率降低期间比特率增加和比特率保存期间附加比特的利用。
