             abstract = "Many computer applications are currently using digital video. 
                         Recent advances in digital imaging and faster networking 
                         infrastructure made this technology very popular, not only for 
                         entertainment, but also in health and education applications. 
                         However, high quality video requires more storage space and 
                         communication bandwidth than traditional data. To deal with this 
                         problem, most of the digital video encoding techniques use a 
                         compression scheme. The MPEG committee has defined widely used 
                         standards for digital video encoding providing high quality images 
                         and high compression rates. However, real-time MPEG encoding also 
                         demands high computacional power, usually far beyond traditional 
                         sequential computers can provide. Fortunately, the algorithms 
                         compliant to the MPEG standard can be parallelized. In this work, 
                         we propose a novel and simple shared-memory parallel algorithm for 
                         MPEG-1 video encoding bassed on the parallel execution of 
                         different coarse grained tasks (read pictures, write coded frames, 
                         I, P, and B frames coding). Two synchronization strategies are 
                         implemented and experimental results show that encoding rates of 
                         43 frames per second are achieved, which is almost 50% better than 
                         the real-time encoding standard rate (30 frames per second).",
