The MC-DCT-based video coding has been generally used for its efficiency and easy implementation, but it is very vulnerable in error-prone environments. In this paper, we address an error-resilient video coding using multiple reference frame, based on the long-term memory motion compensated predicti

Block motion compensation (MC) is widely used in hybrid coding schemes. The presence of motion discontinuities inside the blocks introduces inefficiencies that reduce the performances of MC methods. Moreover the displaced frame difference (DFD) image shows block discontinuities. This fact is the mai
## Abstract Motion compensation is a powerful method to compress a video sequence. However, once an error occurs, the error propagates through the frames. Recently, the intra update method was proposed to stop the error propagation at the cost of the compression efficiency. This paper proposes an i
In this article, we propose an efficient compression algoparameters to fit the very low-bit-rate nature of the applications. rithm for very low-bit-rate video applications. The algorithm is based Despite its good performance, H.263 still suffers from blocking on (a) an optical-flow motion estimation
