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.

Method and apparatus for spatial error concealment of image

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.

Method and apparatus for transmitting packet-based image frame

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.
