Abstract
In this paper, a temporally adaptive layered video coding technique employing the 3-D subband coding (SBC) is proposed. By using the R-D performance measure, the input video is divided adaptively into temporal layers, according to the temporal activity. Then, while the base layer is encoded by H.261, the enhancement layer is encoded by the 3-D SBC technique. From the simulation results, the proposed technique shows about 1 dB PSNR gain over the conventional layered coding techniques, including the twin-H.261, even under heavy ATM network loading.
