A transform-LPC hybrid system for real-time coding of picture data has been presented. The LPC has been made adaptive by using a correlation cancellation loop. Three different schemes for coding and reconstructing the transform components have been presented and their relative performances have been compared. The MSE and SNR are seen to be comparable to previous work on transform-DPCM hybrid schemes.
