The multi object video delivery results in a challenging new bit-allocation, rate-control, and losses protection problem. In this paper, we investigate the use of a FEC-based error control mechanism for error control in multiobject video system, as MPEG-4. Our goal is to achieve object-based unequal error protection, thus assigning different level of protection to the video objects, in order to improve the perceptual video quality at the receiver. We use the dynamic programming approach to optimally select the level of protection to apply to each object. Our results demonstrate that, the video distortion at the receiver can be significantly reduced.
