Another feature of heterogeneous networks is their fluctuating bandwidths. To improve compression ratio, traditional video coding schemes tend to use coarse quatization accuracy, which results in the degradation of visual quality.
异构网络的另一特点是不同网络间带宽变化较大,为了提高视频数据的压缩效率,传统视频编码方法往往采用粗糙的量化以满足带宽瓶颈的限制,其代价是主观视觉质量的下降。
