With the deployment of the fourth generation communication networks, mobile video broadcast services are becoming one of the essential parts of users' daily lives. As an efficient way for mobile video transmission, digital broadcast scheme is faced with the challenge of cliff effect. A novel real-value scheme called SoftCast can eliminate the cliff effect, but not efficient in removing inter- frame correlation. The proposed scheme is similar to SoftCast, and to fully exploit the inter-frame redundancy, motion alignment is involved in the temporal wavelet transform. Then the dense constellation mapping of 64K quadrature amplitude modulation is utilized to maintain the real-value property for wireless transmission. Moreover, metadata is extracted from the previous processes and transmitted in the conventional mechanism to facilitate decoding. Simulation results verify the scalability and robustness of the proposed scheme in the mobile video broadcast applications. |
