1.A group of pictures(GOP) consisted of several successive frames was decomposed by motion-compensated temporal filtering(MCTF) to support temporal scalability by using subband/wavelet transform. Compared with fixed-size GOP,adaptive GOP structure(AGS) could improve the coding performance,but its complexity increased extremely.

6.For this need, its algorithm and technique has already been an extremely active research field in the recent 30 years, also achieves great success in commerce. We have many coding methods in the traditional and developing respect. The traditional methods, for instance, are PCM quantization, spatial and temporal subsampling coding, entropy coding, predictive coding, transform coding, vector quantization(VQ), and subband coding.
