Multimedia transmissions, especially of sport events, are animportant share of the services offered by mobile network operators. Due to limited capacity, lossy compression codecshave to be used, inducing a significant quality degradation. The quality impairments can particularly be observed in soccer games, when the ball is blurred or even totally disappears on low-resolution user terminals. We present a suitable preprocessing of the original video by means of ball sharpening or enlarging in the original video sequence to avoid problems caused by resolution down-sampling and compression. The proposed system includes a novel initial ball-recognition algorithm and an improved ball-trajectory tracking. Our proposed algorithm runs robustly and is computational very economical.
