介绍了小波变换在静态图像压缩、实时连续媒体流等多媒体业务中的应用,并结合ADV611芯片提出一套音视频数据采集压缩的方案。为进一步提高媒体服务质量,在本方案中根据实际情况提出了帧间压缩和码率控制两种解决方法。
The application of wavelet transform in multimedia services such as still image compression and real-time continuous media streaming is introduced. A set of audio and video data acquisition and compression scheme is proposed based on ADV611 chip. In order to further improve the service quality of the media, two solutions of inter-frame compression and rate control are proposed in this solution according to the actual situation.
