Abstract In order to deliver high quality video compressed by H.264/AVC standard with flexible macroblock ordering (FMO) applied over wireless environment, new motion energy based unequal error protection technique (UEP) is proposed. Motion energy (ME) of video frames is computed to determine the importance of frames. According to two different methods in calculating threshold value of motion energy, video frames can be scaled in three different levels and two different levels respectively. Appropriate forward error correction (FEC) codes with various coding rates are applied to different frames according to their importance. In two-level UEP method, low coding rate will be applied for high important frames while low important frames will be protected by the same code with high coding rate. While in three-level UEP method, one more coding rate named as medium coding rate is introduced to operate on middle-important frames. The proposed techniques will be verified by simulations.
