We propose an efficient multiple-input multiple-output (MIMO) video broadcasting technique with low computational complexity that well serves different types of users residing inside the service area of a base station. We consider a video broadcasting scenario in which heterogeneous users with different display resolutions, different operating bit rates, and different numbers of receive antennas are present. Our proposed scheme adopts spatially scalable video coding, and makes use of both spatial diversity and spatial multiplexing techniques. We compare the performance of our proposed scheme with that of a non-scalable video transmission scheme. Simulation results show that our proposed video broadcasting scheme significantly outperforms the non-scalable video broadcasting strategy. The performance improvement is observed for both different types of users we consider.
