Abstract

The subject of the extraction of a dedicated fast playback stream from a normal play MPEG encoded stream is important for recording applications where fast playback is supported by such a device. The most important issue is the selection of the coefficients of codewords to retain for the fast playback stream. In this paper several codeword extraction methods of varying complexity, ranging from optimal extraction methods to a zonal extraction method are evaluated. The range of possible solutions gives the possibility to make a trade-off between performance and complexity. The newly developed selection method, based on a Lagrangian cost minimization per block in combination with a feedback rate control, yields an attractive performance-complexity combination.
