COMMON PREDICTION BLOCK SYSTEM IN SVC DECODER

摘要

PURPOSE: A common prediction block system in SVC(Scalable Video Coding) decoder is provided to design an efficient internal memory usage structure while minimizing the number of gates when implementing hardware of prediction block in an H.264/AVC SE decoder. CONSTITUTION: A first internal memory unit(200) stores data for prediction signal generation. According to a selected prediction mode, a first data module unit(500) arranges data of the first internal memory unit. A common calculation unit(700) calculates the arranged data. A second and a third internal memory units(300,400) receive the calculated value through the second data module unit. A filter coefficient input unit(600) inputs a filter factor to the common calculation unit. A prediction result value storage unit(900) stores a finally calculated prediction result value.
