Introduction

Ram Prabhakar is an accomplished inventor based in Palo Alto, CA. He holds a total of 4 patents that showcase his expertise in the field of data processing and video encoding technologies. His work has significantly contributed to advancements in multimedia applications.

Latest Patents

One of his latest patents is titled "Dynamic packet size control for MPEG-4 data partition mode." This innovation implements a dynamic AC prediction technique that automatically disables AC prediction for encoding the current macroblock in the next packet when packet overflow occurs. When there is no overflow, AC prediction remains enabled to maintain compression efficiency. The process begins with determining whether a macroblock causes a packet overflow if it is encoded in the current packet. If it does, a new packet is initiated, encoding the macroblock without AC prediction as the first macroblock. Otherwise, the macroblock with AC prediction remains in the current packet, and a new macroblock is encoded.

Another significant patent is "MPEG motion estimation based on dual start points." This invention provides a more efficient motion estimation process that utilizes multiple predicted start points based on blocks adjacent to the current block. It requires minimal system resources in its hardware implementation. The technique performs a series of coarse searches using the predicted start positions, followed by a fine search to enhance efficiency.
