Abstract :
The MPEG-2 bitstream syntax offers a great variety of coding mode options for encoding a macroblock. We present an MPEG-2 compliant interlaced video encoder that employs an efficient macroblock coding mode selection method. The macroblock coding mode is selected based on a rate-distortion criterion. However, a computational analysis as well as predictive and statistical modeling techniques are introduced that lead to substantially better computation-performance trade-offs. The proposed MPEG-2 video encoder is shown experimentally to be better than the MPEG-2 TM5 encoder in both compression performance and computation requirements, simultaneously
