Abstract: Methods and apparatuses for data pruning for video compression using example-based super resolution are provided. A method and apparatus for encoding is provided in which patches of video are extracted from input video, grouped together using a clustering method, and representative patches are packed into patch frames. The original video is downsized and sent either along with, or in addition to, the patch frames. At a decoder, the method and apparatus provided extract patches from the patch frames and create a patch library. The regular video frames are upsized and the low resolution patches are replaced by patches from the patch library by searching the library using the patches in the decoded regular frames as keywords. If there are no appropriate patches, no replacement is made. A post processing procedure is used to enhance the spatiotemporal smoothness of the recovered video.

Abstract: The present invention concerns a slot antenna for an electronic device, e.g. a set top box. A printed circuit board (210) comprising a dielectric material (310, 320, 330, 340, 350) and electrodes (240, 360) extends into a rectangular slot (120) in the metal enclosure (110) of the device such that the electrodes are coupled with locations on opposite edges of the long dimension of the rectangular slot. The coupling may be capacitively in order to affect the level of coupling or to optimize the driving point return loss. The presence of the dielectric in the slot allows the use of a shorter slot for a given wavelength.

Abstract: The boot process of a content/service receiver is dynamically monitored to provide error and/or status information in a step-by-step and/or in a single-snapshot manner. This can be accomplished by, for example, utilizing an application thread running within, and/or, outside the context of the boot code. Status information from, for example, software drivers and/or any other software/hardware/middleware components, is acquired by the application thread utilizing any mechanism, for example, event-driven and/or polling, and then relayed to an external entity, which can be locally and/or remotely located. The external entity can be reached by any means of standard and/or proprietary medium and protocols available, if necessary. The relayed information can then be used, for example, for displaying to a user via a graphical user interface, and/or can be recorded and the like.
