Abstract: A method and apparatus for error concealment in image data including a block having an error, the method including: dividing a region that surrounds the block into a plurality of neighboring regions; separately calculating edge angles of the neighboring regions; and selectively performing directional interpolation based on the calculated edge angles.

Abstract: A method and apparatus for transmitting a packet-based image frame, the method including: dividing an input image into intra and inter prediction frames and encoding the intra and inter prediction frames; applying different error resilience algorithms to the intra and inter prediction frames; and performing forward error correction (FEC) on the intra and inter prediction frames according to the corresponding error resilience algorithms. According to aspects of the present invention, optimal error correction may be performed in accordance with characteristics of frames when image data is transmitted. Thus, a strong image streaming service for preventing errors of a mobile environment may be implemented simply and efficiently.

Abstract: A method and apparatus for controlling a consumer electronics (CE) device, are provided. The method includes determining, when a touch is sensed, whether the touch corresponds to a booting request, and performing a booting operation when the touch is a booting request; and controlling the CE device to operate in a sleep mode when an operation start signal is not received until the booting operation is completed, and controlling the CE device to operate in a normal mode when an operation start signal is received before the booting operation is completed. The apparatus includes a touch sensing unit; which senses a touch to the CE device; a determining unit which determines whether the touch sensed by the touch sensing unit corresponds to a booting request; a booting unit, and a control unit controlling the CE device.

Abstract: An error concealment method and apparatus that are adaptive to characteristics of blocks adjacent to a lost block, the adaptive error concealment method including: determining one or more thresholds for selecting an error concealment method, from a plurality of error concealment methods, based on one or more of characteristics of blocks adjacent to a current block having an error; generating a temporal activity and a spatial activity of pixels adjacent to the current block; and selecting an error concealment method, from the plurality of error concealment methods, for the current block according to a result obtained by comparing the temporal activity, the one or more thresholds, and the spatial activity.

Abstract: An apparatus for and a method of controlling battery discharge. A number of battery switching operations is minimized by detecting a remaining voltage capacity of each of a plurality of batteries supplying a battery-powered electronic device with power. The remaining voltage capacities of an internal battery and an external battery are detected and corresponding flags are set for the internal and external batteries according to predetermined conditions. A discharge status of at least one of the internal battery and the external battery is controlled by referring to the flags and a remaining voltage capacity of each of the internal battery and the external battery.
