In this paper, a robust super-resolution method for video transmission over wireless channels is proposed based on the 3-D SPIHT coding algorithm under the wavelet framework. Firstly, a simplified estimator is presented to estimate the lost wavelet coefficients adaptive to the different packet loss condition. And then, in order to enhance the resolution of the image, a convex set which extracts the detail information hidden among the adjacent images is constructed by taking advantage of the correlation of wavelet coefficients. The experimental results show that the robust method outperforms the traditional methods on the aspect of PSNR, especially when the packet loss rate is high.
