Abstract

A parallel decoder for decoding compressed video picture data including inter-coded picture item data with motion vector data. A decoding module decodes picture data stored in a temporary storage. The decoding module includes an inter-prediction module that uses inter-prediction item data to decode an inter-coded picture item by referring to already decoded reference picture item data. The structure of inter-prediction item data in the temporary storage is a function of the positions of corresponding reference picture items. The decoding order of stored inter-prediction item data by the inter-prediction module is prioritized as a function of a decoding order of reference picture item data.
