A Novel Gaming Video Encoding Method Using In-Game Motion Vectors

In this thesis, we introduce a novel video encoding method, which enhances gaming video coding performance by integrating the gaming and the encoding techniques. The method provides a direct motion hint to the encoder via position of objects and motion of the 2D game. In the encoding process, the following three transformations are invoked: a coordination system transformation, determining motion vectors (MVs) of objects in 4x4-checkerboard blocks (Atomic Block, AB), and the selection of proper motion vector for all variety of Prediction Unit (PU) in the encoder. The experimental results show that, compared with the original Diamond Search (DS) method provided by the encoder, our algorithms is able to achieve 14% speed-up of the video encoding process, and a maximum 19% bitrate reduction.
