Patent number: 9609362Abstract: QP control information valid for a block of samples is parsed. A QP to use for the block of samples is derived according to a first QP derivation process independent on the QP control information if residual data of the block of samples is not color transformed and according to a second QP derivation process dependent on the QP control information if the residual data of the block of samples is color transformed. The embodiments thereby decouple QP parameters for blocks of samples that are coded with color transform and those that are coded without color transform. This decoupling achieves better flexibility during encoding and results in better visual quality.Type: GrantFiled: October 2, 2015Date of Patent: March 28, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jonatan Samuelsson, Rickard Sjöberg

Patent number: 9595199Abstract: A preexisting FMS system may be upgraded to increase its functionality while still taking advantage of certain components of the legacy system previously provided on the aircraft and replacing other preexisting components with different components for enhancing the functionality of the FMS system. The preexisting IRU, CADC, DME receiver and DFGC in the upgraded FMS system are in communication with the legacy AFMC but, instead of employing the legacy EFIS which existed in the preexisting FMS system, the EFIS is replaced by a data concentrator unit as well as the display control panel and integrated flat panel display, and a GPS receiver. The upgraded FMS system is capable of such increased functionality as increased navigation database storage capacity, RNP, VNAV and RNAV capability utilizing a GPS based navigation solution, and RTA capability, while still enabling the legacy AFMC to exploit its aircraft performance capabilities throughout the flight.Type: GrantFiled: June 10, 2015Date of Patent: March 14, 2017Assignee: Innovative Solutions & Support, Inc.Inventors: Geoffrey S.

Patent number: 9549174Abstract: Systems and methods for a head tracked stereoscopic display system that uses light field type data may include receiving light field type data corresponding to a scene. The stereoscopic display system may track a user's head. Using the received light field type data and the head tracking, the system may generate three dimensional (3D) virtual content that corresponds to a virtual representation of the scene. The stereoscopic display system may then present the 3D virtual content to a user. The stereoscopic display system may present a left eye perspective image and a right eye perspective image of the scene to the user based on the position and orientation of the user's head. The images presented to the user may be updated based on a change in the position or the orientation of the user's head or based on receiving user input.Type: GrantFiled: October 14, 2015Date of Patent: January 17, 2017Assignee: zSpace, Inc.Inventors: David A.

Patent number: 9549198Abstract: Provided is an apparatus for decoding a moving picture. An inverse quantization/transformation unit generates a quantized block by inversely scanning a quantized coefficient sequence, generates a transform unit by inversely quantizing the quantized block using a quantization step size, and generates a residual block by inversely transforming the transform block. An inter prediction unit generates a prediction block of a current prediction unit based on motion vector information. An adding unit generates a restored block using the residual block and the prediction block. When a motion information coding mode is a skip mode, the inter prediction unit restores motion information of the current prediction block using an available spatial or temporal skip candidate.Type: GrantFiled: March 7, 2016Date of Patent: January 17, 2017Assignee: M & K HOLDINGS INC.Inventors: Soo Mi Oh, Moonock Yang

Patent number: 9521417Abstract: An image encoding device that appropriately estimates a prediction vector by avoiding an uncoded macro block (MB) is disclosed. The device determines a start point of searching a motion vector for an encoding target region, from the prediction vector for the target region which is determined with motion vectors for surrounding blocks around the target region and in accordance with a predetermined rule, and starts searching for the motion vector from the search start point. If the size of the encoding target region cannot be acquired during calculation of the prediction vector, the device determines the size of the encoding target region, from the size of an encoded region other than the target region. If at least one of the motion vectors for the surrounding blocks cannot be acquired, the device calculates the prediction vector using alternatively a motion vector of an encoded block outside of the target region.Type: GrantFiled: October 23, 2012Date of Patent: December 13, 2016Assignee: HITACHI KOKUSAI ELECTRIC, INC.Inventors: Masashi Takahashi, Nobuhiro Chihara, Muneaki Yamaguchi
