Introduction

Ratna M V Reddy is a prominent inventor based in Bengaluru, India. She has made significant contributions to the field of video data encoding, holding a total of 3 patents. Her work focuses on enhancing video compression techniques, which are crucial in today's digital landscape.

Latest Patents

One of her latest patents is titled "Run length encoding in VLIW architecture." This invention describes a computer-implemented method of video data encoding that generates a mask corresponding to each spatial frequency coefficient of a block during quantization. The bit state of the mask is determined by whether the corresponding quantized spatial frequency coefficient is zero or non-zero. The runs of zero quantized spatial frequency coefficients are identified using a left-most bit detect instruction, which is derived from the mask and subsequently run length encoded. The mask is created using a lookup table that maps the scan order of quantization to the zig-zag order of run length encoding. Additionally, variable length coding and inverse quantization can occur within the run length encoding loop.

Another notable patent is "Efficient implementation of H.264 4 by 4 intra prediction on a VLIW processor." This invention is particularly useful in video compression standards that support a variety of intra prediction modes. It introduces a unique table creation and lookup approach to software pipeline the prediction process for all pixels within a block. The table stores both constant data and pointer data into a neighbor pixel table. By indexing into the table based on the current intra prediction mode for each pixel of a block, the invention recalls constant data and other pixel data necessary for calculating an intra prediction value.
