Publication number: 20100246677Abstract: A sequence to be encoded is divided into a plurality of temporal portions or chunks. The sequence is then analysed to determine for each chunk, in accordance with a plurality of encoding quality settings, data establishing the relationship between the quality settings and (i) a quality metric for the portion and (ii) the number of bits generated by encoding the portion at that quality setting. Given a target quality, a target bit rate is then set (or vice versa); then one chooses a set of quality settings, one per chunk, that tends to minimise a combined quality cost for the sequence within the constraint that transmission of encoded video at the target bit rate via transmitting and receiving buffers of specified size and initial receiver buffer fullness shall not cause underflow nor overflow.Type: ApplicationFiled: October 29, 2008Publication date: September 30, 2010Inventor: Michael Erling Nilsson

Patent number: 7792191Abstract: A half-pixel accuracy fast search algorithm in video coding performs a hierarchical search method for motion estimation, which initially searches integer accuracy motion vector and then continues its search sub-pixel accuracy over surrounding reconstructed sub-pixels of the integer motion vector. The term hierarchical connotes that the algorithm first calculates a minimum integer pixel location and then performs a sub-integer pixel search. The present invention obtains the integer pixel value with the lowest MAD value and then interpolates conjugate half-pixel values in a first direction. The algorithm determines which half-pixel value yields the lowest MAD value and then interpolates conjugate half-pixel values in a second direction from the previously calculated minimum MAD half-pixel location from the first direction.Type: GrantFiled: March 8, 2002Date of Patent: September 7, 2010Assignee: Lambert Everest Ltd.Inventor: Nyeongkyu Kwon

Patent number: 7751482Abstract: Motion vectors for encoding a predicted frame relative to a reference frame are determined from a phase correlation of corresponding regions of the predicted frame and reference frame. Peaks in the phase correlation are identified, and the location of the peaks are used as candidate motion vectors. From this limited set of candidate motion vectors, the best motion vectors for predicting blocks within each region can be readily identified.Type: GrantFiled: February 27, 2004Date of Patent: July 6, 2010Assignee: VBrick Systems, Inc.Inventors: Deepika Srinivasan, Andew T.
