Mathias WienInstitute for Communications EngineeringAachen University of Technology für Nachrichtentechnik, Melatener Str. 23, Aachen New ABT Results using CABAC VCEG-N49 Mathias Wien Institut für Nachrichtentechnik RWTH Aachen, Germany

Mathias WienInstitute for Communications EngineeringAachen University of Technology für Nachrichtentechnik, Melatener Str. 23, Aachen VCEG N49 Adaptive Block Transforms Macroblock Modes Proposal Adaptive Block Transforms Transform block size connected to MC block size No additional side information Exploit signal length Definition of transforms, motion estimation, deblocking filter in VCEG-M62

Mathias WienInstitute for Communications EngineeringAachen University of Technology für Nachrichtentechnik, Melatener Str. 23, Aachen VCEG N49 CBPY Coding Number of encoded CBPY bits is MB mode dependend Context generation –Blocks larger than 8x8 treated as combinations of 8x8 blocks

Mathias WienInstitute for Communications EngineeringAachen University of Technology für Nachrichtentechnik, Melatener Str. 23, Aachen VCEG N49 Level Coding Binarization and context generation taken form TML. MB Mode 1-4 –Exploit CBP block size == transform block size no EOB as first symbol MB Mode 5-7 –Encoding same as encoding levels in TML 4x4 blocks

Mathias WienInstitute for Communications EngineeringAachen University of Technology für Nachrichtentechnik, Melatener Str. 23, Aachen VCEG N49 Run Coding New binarization, MB mode dependend –Unary binarization for the first 3 run symbols –Fixed length binarization for the remaining runs Number of Bins mode dependend –13 run contexts Contexts for the Run Bins Run Binarization
