Abstract
This report is based on a 成人快手 tutorial paper describing several bit-rate reduction techniques which have been studied at the 成人快手 and which are used for the transmission of digital television signals. The techniques described are Sample-Rate Reduction, Differential Pulse Code Modulation (DPCM) coding - including a review of linear prediction theory and quantisation, Transform Coding (DCT), Entropy Coding and Vector Quantisation. The text of the tutorial was first prepared in 1986 before some of the recent advances in low bit-rate coding for television involving techniques such as motion compensated interframe prediction and subband coding. However, the material presented here continues to prove itself to be a useful introduction to the subject and therefore it has been reprinted in the hope that it will give useful insights to engineers requiring a reasonably detailed introduction to bit-rate reduction of television signals.
