METHOD AND APPARATUS TO INTERPOLATE AND FRAME ADDING THE BASE AND ENHANCEMENT LAYER IN SCALABLE VIDEO CODING

摘要

A METHOD AND APPARATUS IN SCALABLE VIDEO STREAMING IS DISCLOSED. THE APPARATUS COMPRISES AN INTERPOLATER FILTER (101) AND A FRAME ADDER FILTER (102). THE FORMAT FOR INPUT AND OUTPUT IS YV12. THE METHOD COMPRISES THE STEP OF USING ENTROPY CODING ALGORITHMS TO PROCEED WITH DECODING PROCESS; EMPLOYING IDCT AND INVERSE QUANTIZATION ALGORITHM TO DECODE FRAMES; USING MOTION ESTIMATION (ME) AND MOTION COMPENSATION (MC) PREDICTION ALGORITHMS FOR P AND B FRAMES; AND UPSAMPLING THE BASE LAYER FROM QCIF FORMAT TO CIF FORMAT USING NEAREST NEIGHBOR INTERPOLATION TO OBTAIN AN INTERPOLATED FRAME (301).
