| 7. | Moreover , a newly mpeg - 4 has become mature and a necessary basic standard for the implication of streaming media . with the high compress rate , high mutual ability and flexible scalable ability ; mpeg - 4 has a bright future for use in streaming media 另一方面,新一代的音视频压缩标准mpeg - 4不断走向成熟,成为视频应用的不可或缺的一个基础标准,它具有的高压缩率、强交互能力和灵活分级能力,使之在网络流媒体特别是视频点播中拥有广阔的应用前景。 |
| 8. | At present . the jpeg stationary picture compressing standard has a good compressing effect on middle and high compressing rate . but there exists a serious diamond effect at low compressing rate . on the side , jpeg standard can not very well make the needs transmitting mages by networks at low compressing rate 目前的jpeg图像压缩标准,在中高码率上压缩效果较好,然而在低码率的情况下,重构图像存在严重的方块效应,不能很好地适应网络传送图像的需要。 |
