Error-Resilient Delivery Of Region Of Interest Video Using Multiple Representation Coding

Video delivery over wireless and cellular networks can be severely impaired due to bandwidth limitations and also due to the presence of burst losses and signal-loss intervals. This paper proposes unequal protection of Region of interest (ROT) encoded videos for transmission over low-bitrate and error-prone channels. Here, a flexible and interactive ROT is introduced in a low-complexity, and standard-compliant fashion to encode the critical regions within each frame at a higher quality as compared to the background. Further, the reconstruction fidelity of the high-quality ROT is improved by unequally protecting the ROT using an error-resilient video delivery scheme known as Multiple Representation Coding (MRC). Simulation results indicate that the proposed strategy can facilitate a graceful recovery of the ROT in the presence of burst and signal losses.
