“…Video quality is improved by increasing the number of slices per frame, at the expense of reducing coding efficiency of the transmission network. Recently, an unequal error protection technique was proposed based on the Motion Energy (ME) of a block [8]. Motion energy is defined as the product of block size and the distance of block moved between two consecutive frames.…”

This paper presents an unequal error protection technique for H.264/AVC video bitstreams. It is formed by the concept of motion energy, which is defined as the energy necessary for displacement of blocks between two frames having motion information. The importance of frames are adaptively set by threshold values, which are calculated based on variation of motion energies between consecutive frames. Simulations show that the proposed technique effectively improves the quality of compressed videos formed by different formats.

“…The importance of a video frame is conventionally evaluated by motion activity. In [10], we define the motion energy of a sub-macroblock as the product of the motion vector magnitude and size of a sub-macroblock. Then, the motion energy of a frame is determined by total motion energies of sub-macroblocks, which is given …”

A multi-level error protection technique for H.264/AVC video bitstreams structured by Group of Pictures (GOP) is proposed. Protection levels are determined by motion energy, which considers displacements of all macroblocks between consecutive frames. Lagrange polynomial is applied in predicting motion energy of a GOP, which is derived from previous GOPs having a high correlation with each other.The optimum number of previous GOPs is selected in order to obtain a good motion energy estimation of the current one. Conducted analyses and simulation results show that video performance obtained by the proposed technique outperforms other motion activity-based Unequal Error Protection (UEP) techniques, while a similar channel code rate is applied.
