Abstract:
1. A method for parallel encoding of digital pictures, comprising: a) partitioning a digital picture into two or more vertical sections; b) selecting an encoder unit from a system having one or more encoder units to serve as a master; c) selecting one or more encoder units from the system of one or more encoder units to serve as slaves, where the total number of encoder units used equals the number of vertical sections; d) performing a mode search on the two or more vertical sections on a row-by-row basis; e) performing entropy coding on the two or more vertical sections on a row-by-row basis, wherein the entropy coding of each vertical section is performed in parallel such that each encoder unit performs entropy coding on its respective vertical section; and f) performing de-blocking on the two or more vertical sections on a row-by-row basis, wherein the de-blocking of each vertical section is performed in parallel such that each encoder unit performs de-blocking on its respective vertical section, wherein f) includes, for a given encoder unit: i) performing de-blocking of only a first portion of the edges of each subsection within the given encoder unit's section that is a section boundary subsection for another encoder unit; ii) performing de-blocking of all edges of each subsection within the given encoder unit's section that is not a section boundary subsection for another encoder unit iii) performing de-blocking on a second portion of the edges of a sub-section in an adjacent section that is a section boundary sub-section for the given encoder unit.
