Claim Text:
1. A method for determining a macroblock (MB) coding mode for a current MB in a dependent view, comprising: determining a window around a co-located MB and neighboring MBs in a base view, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view; determining a coding mode complexity value for the co-located MB and each neighboring MB in the window, wherein the coding mode complexity value is based on one of a plurality of coding modes; comparing a total coding mode complexity value of the co-located MB and each neighboring MB in the window to a threshold value, wherein the total coding mode complexity value is calculated using more than one of the plurality of coding modes; performing rate distortion optimization (RDO) for the current MB using a first number of coding modes when the total coding mode complexity value of the co-located MB and each neighboring MB in the window is less than the threshold value; performing RDO for the current MB using a second number of coding modes greater than the first number of coding modes when the total coding mode complexity value of the co-located MB and each neighboring MB in the window is greater than or equal to the threshold value; and determining a coding mode for the current MB based on the RDO results.
