针对手机、平板等移动终端在观看视频时屏幕大小受限，为了不影响便携性要求，且获得大屏幕视觉效果，提出一种Android平台的多移动终端拼接显示技术。在Android平台下，对视频进行切割，将切割后的图像，经过H.264进行编解码。利用RTP协议传输切割后的图像，对扩屏后的图像采用自适应三次样条插值算法调整分辨率。通过对比，扩屏后的图像经过自适应三次样条插值算法调整分辨率后，视觉效果明显优于其他方法的图像。实验结果表明，对于MP4格式的1080p视频，将其切割为每秒18帧进行传输，这样即可流畅的播放视频；其次，通过对比几种插值算法，本实验采用自适应三次样条插值，保证了扩屏后图像的清晰度。

Aiming at the mobile terminals such as mobile phone and pad, while watching the video, the screen size limited. In order to obtain larger screen visual effects and the requirements without affecting, in this paper, a multi-screen mosaicing displaying technology based on Android platform is proposed. Firstly,video segmentation is pro-cessed,the segmentation images are encoded and decoded by using H.264 compression and transmitted by using RTP protocol. More clear images are achieved by applying adaptive cubic spline interpolation technique.By contrast,the adap-tive cubic spline interpolation is better than other methods. The results show that smooth playback of video can be achieved by cutting the MP4 fomat of 1080p video to 18per second for transmission. And the adaptive cubic spline in-terpolation can ensure the clarity of the screen image expansion.
