We propose a very simple scalable video coding (SVC) system based on the H.264 baseline profile codec. The proposed SVC algorithm can offer three levels of the temporal and spatial scalability - QVGA@15fps, QVGA@30fps, and VGA@30fps. The proposed system achieves the temporal scalability by encoding every other picture as the non-reference P-picture, so that the base layer codec dealing with the QVGA@15fps sequence is fully-compatible with the satellite-digital multimedia broadcasting (S-DMB) system in Korea. In addition, the same decoder can reconstruct the QVGA@30fps sequence when it receives the bits representing the non-reference pictures. For the spatial enhancement layer, the encoder follows the standard H.264 baseline profile except the inter-layer intra prediction. To reduce the computational burden of the encoder, the enhancement layer encoder may skip the motion estimation procedure by interpolating the motion field with that of the base layer. Simulation results show that the proposed system yields less then about 12% of loss in the reconstruction picture quality compared with the anchor H.264 JM encoder. The proposed SVC system still has a room for improvement of coding efficiency by trading with the computational complexity, so that lots of further works are required.
