What are the Motion Estimation Algorithms being supported by the TI encoder?
For the 720p encoder, we support 3 types of Motion Estimation. ME Type 0 (or Original ME) is recommended for resolutions greater than or equal to D1. ME Type 1 (Low Power ME) is a modification of the Original ME to reduce the DDR BW. Similar to the Original ME, the LPME is recommended for resolutions of D1 and above. Both the LPME and original ME give 1 MV/MB. For resolutions below D1, it is recommended to use ME Type 2 (Hybrid ME). This algorithm gives upto 4 MV/MB. The encoder offers the flexibility to the application to select any of the 3 ME schemes during the codec instance creation. For the 1080p encoder, currently we support the Decimated ME Scheme ( a coarse search followed by a refinement search). This ME scheme is different from the ME schemes in the 720p encoder. Decimated ME is suitable for high resolution and high motion sequences. It is recommended that the Decimated ME be used for 1080p resolution. Note that Decimated ME generates 1 MV/MB. There is a plan to add the LPME
