Abstract:
Disclosed is a method of decoding a plurality of coding units from a bitstream of video data. The method determines a coding unit structure of the plurality of coding units from a first data block of the bitstream. The coding unit structure describes a division of a coding unit into the plurality of coding units. The method decodes, according to the determined coding unit structure, bypass encoded data for the plurality of coding units from a second data block of the bitstream. The method decodes, according to the determined coding unit structure, residual data for the plurality of coding units from a third data block of the bitstream. The method then forms the plurality of coding units from the bitstream using the residual data and the bypass encoded data. A method of encoding is also disclosed.
Abstract:
A method and apparatus for clipping a transform coefficient are disclosed. Embodiments according to the present invention avoid overflow of the quantized transform coefficient by clipping the quantization level adaptively after quantization. In one embodiment, the method comprises generating the quantization level for the transform coefficient of a transform unit by quantizing the transform coefficient according to a quantization matrix and quantization parameter. The clipping condition is determined and the quantization level is clipped according to the clipping condition to generate a clipping-processed quantization level. The clipping condition includes a null clipping condition. The quantization level is clipped to fixed- range represented in n bits for the null clipping condition, where n correspond to 8, 16, or 32. The quantization level may also be clipped within a range from -m to m-1 for the null clipping condition, where m may correspond to 128, 32768, or 2147483648.
Abstract:
A method of operating a mobile device with a camera, a display and a position sensor to provide a display of supplementary information aligned with a view of a scene. One or more image obtained from the camera is uploaded to a remote server together with corresponding data from the position sensor. Image processing is then performed to track image motion between that image and subsequent images obtained from the camera, determining a mapping between the uploaded image and a current image. Data is then received via the network indicative of a pixel location for display of supplementary information within the reference image. The mapping is used to determine a corresponding pixel location for display of the supplementary information within the current image, and the supplementary information is displayed on the display correctly aligned with the view of the scene.
Abstract:
An apparatus and a method for using a frequency hopping scheme in a broadcast communication system are provided. A method for transmitting a broadcast signal via at least two frequency bands by a transmission end device in the broadcast communication system includes determining a frequency hopping pattern for providing a broadcast service and transmitting the same; transmitting control information via a first frame after a frequency is changed according to the frequency hopping pattern; and transmitting broadcast data for the broadcast service via a frame transmitted after the first frame.
Abstract:
A surveillance system (10) for monitoring movement in a region of interest (18) is described. The surveillance system (10) includes: An image capturing system (12) having a field of view (16) including a region of interest (18), and adapted to capture an image of the region of interest (18). An image processing system (78) configured to process a time-sequential series of images of the field of view from the image capturing system such that at least a portion (52, 53, 54) of each processed image (50) is analysed for detecting movement within the region of interest (18). The image capturing system (12) is configured to capture, in each image, different apparent magnifications of respective zones (20, 22, 24) within the region of interest (18) in the field of view (16) that are at different distances from the image capturing system (12) such that an object (60) in at least one position in at least two of said zones has substantially the same apparent size in the images.

Procédé de substitution d'au moins un serveur de contenus (DMS1, DMS2) par un serveur de substitution (ADMS) connecté à un réseau, le procédé étant mis en œuvre par le serveur de substitution (ADMS) et comprenant: une étape d'émission, vers un serveur de contenus à substituer, d'un premier message à réception duquel ledit serveur de contenus se déclare absent dudit réseau; une étape de référencement dans un répertoire de contenus du serveur de substitution d'au moins un contenu référencé dans un répertoire de contenus dudit serveur de contenus; une étape d'émission d'un message d'annonce par lequel le serveur de contenus signale sa présence dans le réseau.
Abstract:
A presente patente corresponde a uma solução tecnológica integrada que envolve sistema e processo de sincronização entre o conteúdo programático e de publicidade veiculada no meio televisão, por meio temporal (data, hora. minutos, segundos e milissegundos), com um sistema web e/ou aplicativos mobile que permitem a disponibilização de mais informações e interatividade relacionada ao conteúdo exibido; método e sistema possibilitam que mini-aplicativos interativos em plataformas web, mobile e redes sociais, sejam apresentados em sincronia com a grade de programação e publicidade veiculados pelas emissoras de televisão, cujo objetivo é apresentar informações e possibilitar a relação entre telespectadores, programação e anunciantes ao permitir interação sincronizada a todo conteúdo exibido pela emissora de tv, em rede nacional ou regional.
Abstract:
The present idea refers to a method and a control unit for controlling a display (19). Vehicles and other objects (4a, 4b, 4c, 5, 6, 7, 8), for example, in a surface mine (1), are equipped with range cameras (12). A control unit (13) of such object (4a, 4b, 4c, 5, 6, 7, 8) receives signals representative of range images from these at least two range cameras (12). The at least two range images are evaluated and a subset of range images is selected from the range images available subject to the result of the evaluation. A control signal is provided to the display (19) for displaying image information stemming from the one or more range cameras (12) in charge of providing the one or more range images selected for the subset. By such method, the most relevant scene in terms of collision avoidance can be displayed to the personnel in charge.
