Optimized Packetization of H.264 SVC Bitstreams for MIMO Wireless Video Streaming

Wireless video transmission over multiple-input multiple-output (MIMO) systems is a challenging theme. Eigen beam-space division multiplexing (E-SDM) is an optimal beamforming technique in terms of channel capacity when the transmitter and receiver can share channel state information. E-SDM sorts the channel quality from the highest signal-to-noise ratio (SNR) to the lowest one. This paper presents the video transmission scheme for H.264 scalable video streams over MIMO E-SDM with optimized packetization. The proposed method controls the ratio of a base layer and enhancement layers contained in a packet. The result shows that the optimized ratio is obtained when a packet consists of the lowest base layer ratio. This ratio provides the 39.9 dB of peak-signal-to-noise ratio after decoding while no frame can be decoded with the other ratio at SNR of 10 dB.
