One of the important issues of green mobile networking is the low energy consumption for either mobile devices or transmissions. To adapt this, a lowcost Inter frame mode decision (MD) algorithm is proposed for H.264/AVC encoder to reduce the computational complexity of the original encoding procedure in this paper. The information extracted from macroblock (MB), such as energy, temporal domainmode similarity and so on, which can be used to pre-estimate the optimal mode of theMB is investigated and utilized to eliminate the redundant mode candidates. The performance evaluations including quantitative analysis and PC simulations show that the proposed algorithm is an energyefficient source coding because it can reduce around 85% Inter frame encoding time with little quality loss. It can be widely implemented in green mobile networking systems with H.264/AVC standard to realize the realtime video signal coding.
