A method and device for transmitting and receiving a video stream are provided. The transmitting method includes receiving auxiliary information and one or more video streams, and distributing them as one or more pieces of lane data; transmitting the lane data to a receiving device; and receiving a result value that indicates whether a video processing unit for processing one of the one or more video streams works normally. The receiving method includes receiving one or more pieces of lane data that include auxiliary information and one or more video streams; merging the lane data into one or more video streams; selecting a video processing unit based on the auxiliary information, where one or more video processing units process the video streams; generating a result value for the selected video processing unit that indicates whether the video processing unit works normally; and transmitting the result value to a transmitting device.

A multi-band built-in antenna of a portable terminal is provided. The antenna includes a first antenna radiator on a front surface of a substrate (e.g., a main board), and a second antenna radiator on an opposite surface of the substrate. The substrate has ground surfaces on both sides separated from a non-ground area on which the radiators are disposed. The first radiator may be in the form of a Planar Inverted F Antenna (PIFA), with a first end branched off into two parts, one part used for power feeding and the other part electrically coupled to the ground surface. The first radiator has a portion that extends from the first end to an opposite end. The second radiator is continuous from the opposite end of the first radiator through a via (hole) in the main board.

An electronic device includes first and second interconnections formed on a first surface of a substrate and spaced apart from each other. The electronic device includes a first insulating material layer disposed on the substrate including the first and second interconnections and including a first opening exposing a predetermined region of the first interconnection. The electronic device further includes a first pad filling the first opening and having a greater width than the first opening. The first pad covers at least a part of the second interconnection adjacent to one end of the first interconnection, and the first pad is electrically insulated from the second interconnection by the first insulating material layer.

A GPS signal receiving method in a mobile terminal having a first reception path and a second reception path is provided. Upon request for GPS signal reception while receiving a CDMA signal in the first reception path, the received strength of a GPS signal is measured. If the GPS signal strength is equal to or greater than a predetermined threshold, the GPS signal is received in the first reception path. If the GPS signal strength is less than the predetermined threshold, the GPS signal is received in the second reception path.
