- Abstract
- Resent studies [1]-[3] have indicated that a significant improvement in wireless video throughput can be achieved by Cross Layer Design with Side-information (CLDS) protocols. In [18], for real-time video streaming over wireless LANs the optimal rate prediction architecture under CLDS (ORPA CLDS) was developed. In [18], we showed that an accurate source and channel coding rate prediction can be achieved by utilizing the video quality models and the distribution of channel prediction error process under CLDS. To optimally utilize ORPACLDS, the video quality function for rates exceeding the channel capacity (i.e., video rate-distortion function) should be taken into consideration. To this end, in this paper we propose an empirical model for video rate-distortion. To deduce the generic video ratedistortion model, actual Scalable Video Coding (SVC) [20] and Low Density Parity Check (LDPC) code [17] were used. The outstanding performance of ORPACLDS in accordance with the video rate-distortion model is exhibited by using a comprehensive set of IEEE 802.11b wireless traces. © 2008 IEEE.
