Abstract

Video transmission requires the delivery of video content to a broad range of end users with different bandwidth and resource constraints. One solution to transmitting video over bandwidth-constrained channels is to transmit a low-resolution version of video as a trade off for the bit-rate. In this paper, we proposed an arbitrary downsizing algorithm. This algorithm can downsize the frame to arbitrary size and process it directly in DCT domain. Experimental results show that the proposed method can achieve a comparable performance. Compared with the existing methods, this algorithm is not only applicable to intra coding frame but also inter coding frame. This is one of the crucial features of this method.
