Other scalability modes were experimented with in MPEG-2 video (such as Frequency Scalability), but were eventually dropped in favor of methods that demonstrated similar quality and greater simplicity. What is the TM rate control and adaptive quantization technique ?
Test model was not by any stretch of the imagination meant to be the show-stopping, best set of algorithm. It was designed to exercise the syntax, verify proposals, and test the *relative* performance of proposals in a way that could be duplicated by co-experimentors in a timely fashion. Otherwise there would be more endless debates about model interpretation than actual time spent in verification. [MPEG-2 Test model is frozen as v5b] The MPEG-2 Test Model (TM) rate control method offers a dramatic improvement to the Simulation Model (SM) method used for MPEG-1. TM’s improvements are due to more sophistication pre-analysis and post-analysis routines. Rate control and adaptive quantization are divided into three steps: Bit Allocation In Complexity Estimation, the global complexity measures assign relative weights to each picture type. These weights (Xi, Xp, Xb) are reflected by the typical coded frame size of I, P, and B pictures (see typical frame size section). I pictures are assigned
