Abstract: The present invention relates to an intra-prediction method and to an encoder and decoder using same. The intra-prediction method according to one embodiment of the present invention comprises the steps of: deriving a prediction mode of a current block; and generating a prediction block with respect to the current block on the basis of the prediction mode of the current block. When the prediction mode of the current block is an intra-angular prediction mode, values of boundary samples from among left boundary samples and upper boundary samples of the prediction block, which are not positioned in a prediction direction of the intra-angular prediction mode, are derived on the basis of reference samples positioned in the prediction direction of the intra-angular prediction mode, and on the basis of adjacent reference samples.

Abstract: The present invention is generally related to video assemblies and more particularly video assemblies for on-board entertainment systems. The video assembly may include a video arm coupled with a video monitor. The video assembly may be manually moveable by a user between a stowed position and a deployed position. The video arm may include a friction torque device. The video arm may provide variable resistance depending on a direction of movement of the video assembly. In some embodiments, the video arm may provide less resistance to a user when the user moves the video assembly toward the deployed position compared to the resistance provided to a user when the user moves the video assembly away from the deployed position. Further, the video arm may provide for a low torque zone where the resistance provided to a user is reduced when the user moves the video assembly through low torque zone.

Abstract: Various corporate, industry, and regulatory guidelines, best practices and standards are used in establishing acceptable levels of accuracy for volume dimensioning systems used in commerce. A volume dimensioning system can determine at least one distortion value that is indicative of an amount of distortion present in the system and responsive to the amount of distortion, autonomously alter or adjust the units of accuracy of information reported by the system. Such alteration or adjustment of units of accuracy may be performed based on an assessment of the distortion relative to a number of distortion thresholds. Responsive to the assessment, the volume dimensioning system can adjust a unit of accuracy in a representation of volume dimensioning related information.
