Publication number: 20210014502Abstract: Several methods and systems for encoding of multimedia pictures are disclosed. In an embodiment, an occupancy level of a coded picture buffer (CPB) associated with a hypothetical reference decoder (HRD) is estimated at an instant of removal of an access unit corresponding to a multimedia picture from the CPB for decoding the access unit. A number of bits for encoding the multimedia picture is allocated based on the estimated occupancy level of the CPB. The multimedia picture is encoded based on the allocated number of bits.Type: ApplicationFiled: September 28, 2020Publication date: January 14, 2021Inventors: Arun Shankar Kudana, Uday Pudipeddi Kiran, Anurag Mithalal Jain, Soyeb Nagori

Patent number: 10593019Abstract: A method and apparatus for storing, processing and reconstructing full resolution image out of sub band encoded images are provided. The method of rendering high resolution images based on sub-band encoded data of an image includes steps of performing downscaling of a selected image, creating a time-stamped downscaled image, extracting sub-band information associated with the selected image at one instance in time, compressing the downscaled image and the sub-band information, and decompressing and adding the sub-band information with extrapolated downscaled image to reconstruct and render high resolution image.Type: GrantFiled: October 15, 2015Date of Patent: March 17, 2020Assignee: Samsung Electronics Co., Ltd.Inventors: Anurag Mithalal Jain, Ravindranath Ramalingaiah Munnan, Venkata Ravisankar Jayanthi, Rajat Agarwal, Ashish Ranjan, Joy Dutta, Yongman Lee, Sungoh Kim, Jae Hun Cho, Kwangyoung Kim, Hyunhee Park

Patent number: 8213511Abstract: This invention is a method of video encoding. The number N macroblocks stored in a temporary buffer depends upon an estimated number of motion vectors. N macroblocks of current and prior frame data is transferred to the temporary buffer. The invention determines for each macroblock whether to be inter frame predicted or intra frame predicted. The inter and intra macroblocks are separately encoded based upon this determination and stored in an output buffer. Output macroblocks are output from the output buffer in raster scan order. This technique permits the process to loop over differing number of macroblocks in differing parts of the encoding process. Entropy encoding complexity from separating inter and intra macroblock encoding is avoided by separating a symbol generation phase from an encoding phase.Type: GrantFiled: April 29, 2008Date of Patent: July 3, 2012Assignee: Texas Instruments IncorporatedInventors: Pramod Kumar Swami, Venugopala Krishna Madumbu, Anurag Mithalal Jain, Jacques Michel Bride, David Gottardo

Patent number: 7778494Abstract: A half sample and quarter sample pixel value interpolation calculation classifies a set of all possible half sample and quarter sample pixel value interpolation calculations into a plurality of interpolation types. A function kernel for each interpolation type includes a half sample pixel and all quarter sample pixels whose value calculation depend on a value of said half sample pixel value. The correct function kernel is called invoking the corresponding value interpolation calculation. The function kernels operate iteratively over a plurality of macroblocks of at least two macroblock sub-partition sizes. The calculation of dependent quarter sample pixel values preferably employs a packed average instruction.Type: GrantFiled: October 13, 2006Date of Patent: August 17, 2010Assignee: Texas Instruments IncorporatedInventors: Pavan V. Shastry, Sunand Mittal, Anurag Mithalal Jain, Ratna M. V. Reddy

Publication number: 20080298472Abstract: Improving throughput performance when applying deblocking filters on reconstructed image frames. In one embodiment, an image frame received in the form of a set of values in encoded format is decoded to form a second set of values representing a reconstruction of the image frame in a decoded format. The specific one of the pairs of edges (formed by sub-blocks in the image frame) to which a deblocking filter is to be applied is then determined by evaluating any pre-conditions that need to be satisfied according to a standard. The deblocking filter is then applied to the determined specific ones of the pairs of edges, with the application being performed after determining.Type: ApplicationFiled: April 23, 2008Publication date: December 4, 2008Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Anurag Mithalal Jain, Vipulkumar Parasottambhai Paladiya, Sunand Mittal
