Publication number: 20150156498Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.Type: ApplicationFiled: October 1, 2014Publication date: June 4, 2015Inventors: Vijayalakshmi R. RAVEENDRAN, Gordon Kent WALKER, Binita GUPTA, Phanikumar Kanakadurga BHAMIDIPATI, Bruce COLLINS, Devarshi SHAH, Robert Sean DALEY, Sten Jorgen Ludvig DAHL, Serafim LOUKAS, Bharat AHUJA, Thadi Manjunath NAGARAJ, Vinod KAUSHIK, Prasanna KANNAN

Publication number: 20140177703Abstract: This disclosure describes techniques for controlling a perceived quality of multimedia sequences to try to achieve a desired constant perceptual quality regardless of the content of the sequences. In particular, an encoding device may implement quality control techniques to associate a sequence segment with a content “class” based on the content of the segment, determine a perceptual quality metric of the sequence segment, and adjust at least one encoding parameter used to encode the segment is encoded such that for the perceptual quality of the sequence segment converges to the desired quality.Type: ApplicationFiled: October 11, 2013Publication date: June 26, 2014Applicant: QUALCOMM IncorporatedInventors: Devarshi Parashar Shah, PhaniKumar Bhamidipati, Vinod Kaushik, Serafim S.

Patent number: 8311120Abstract: This disclosure describes techniques for coding mode selection. In particular, an encoding device determines whether or not to code a block of pixels in a coding mode currently being considered for selection using information associated with at least one other coding mode with a different block partition. In one aspect, the encoding device uses information associated with at lest one coding mode that has block partitions that are sub-partitions of the block partitions of the coding mode currently being considered for selection. Additionally, the encoding device may use information associated with another coding mode that has the same block partitions as the coding mode currently being considered for selection or information associated with the coding mode currently being considered for selection.Type: GrantFiled: August 31, 2007Date of Patent: November 13, 2012Assignee: Qualcomm IncorporatedInventor: Vinod Kaushik

Patent number: 8150172Abstract: A method and system for coding mode selection using estimated coding costs. To provide high compression efficiency, for example, an encoding device may attempt to select a coding mode for coding blocks of pixels that codes the data of the blocks with high efficiency. To this end, the encoding device may perform coding mode selection based on estimates of coding cost for at least a portion of the possible modes. The encoding device may estimate the coding cost for the different modes without actually coding the blocks. In fact, in some aspects, the encoding module device may estimate the coding cost for the modes without quantizing the data of the block for each mode. In this manner, the coding cost estimation techniques may reduce the amount of computationally intensive calculations needed to perform effective mode selection.Type: GrantFiled: May 4, 2007Date of Patent: April 3, 2012Assignee: Qualcomm IncorporatedInventors: Sitaraman Ganapathy Subramania, Fang Shi, Peisong Chen, Seyfullah Halit Oguz, Scott T.
