Abstract: The mobile communication terminal capable of accessing to a plurality of heterogeneous networks selectively, according to the present invention, comprises a process which communicates data with an application running on the mobile communication terminal, through a local socket created with its destination address set to a fixed internal address; and another process which creates at least one outward socket by setting its source address to an IP address assigned from one of the plurality of heterogeneous networks and its destination address to a remote address, and communicates data with an outside server of the remote address through the at least one outward socket. Data communication is made between the local socket and the at least one outward socket if the at least one outward socket is set as associated with the local socket.

Abstract: A wireless communication terminal according to the present invention, if it is found that an access point (AP) is available from searching a wireless communication network, for example, a Wi-Fi network, checks whether the AP is registered in a list of delayed access points. If the access point in included in the list of delayed access points, the wireless communication terminal re-searches the Wi-Fi network after a predetermined waiting time is passed. If the AP is unavailable, connection to a current mobile communication network is maintained whereas, if the AP is still available, the wireless communication terminal switches connection from a mobile communication network to the AP. If not registered in a list of delayed access points, the wireless communication terminal immediately switches connection from a mobile communication network to the AP without the waiting time.

Abstract: A terminal according to the present invention comprises a relaying unit. The relaying unit requests list information of sections to a remote site with respect to a content selected by an arbitrary entity and receives it therefrom. Then, the relaying unit receives sections pertaining to the content by requesting them to a remote site with reference to information included in the received list information. When a request for list information of the content is received from another entity, the relaying unit draws up list information for sections listed in the received list information and provides it to the another entity as a response to the received request. While drawing up the list information, the relaying unit changes remote source information about an arbitrary section listed in the received list information to local source information including a pathname assigned to a repository allocated for storing data of the arbitrary section.

Abstract: A wireless terminal of the present invention determines a section to be skipped on data of a selected content from the last position of unprocessed data based on information about dynamic state of the unprocessed data that has been received but is not played yet, if a requirement for using the second wireless network is satisfied while media data of the selected content is being received from an external server through the first wireless network. After determination of the section to skip, the wireless terminal transmits a transfer request demanding data right after the determined section to the external server through the second wireless network.

Abstract: A mobile communication terminal according to the present invention comprises a processing unit for carrying out an operation intended for a data object such as content or a program, a channel builder for establishing a data channel for providing a data object to, for example, a player or a browser; and a data transceiver, while being connected to one of communication networks among a plurality of heterogeneous networks, for receiving a data object from an external server through the communication network, providing the received data to the processing unit through the data channel, checking the amount of remaining data to receive from the data object.

Abstract: Techniques, apparatus and systems for image decoding are described. A method performed by an image decoding apparatus includes generating motion compensation information and a quantized result of an error image that represents a difference between a current image to be decoded and a prediction image obtained by performing inter prediction on the current image from a bitstream of the current image. A reference image of the current image is received from an external memory unit based on the generated motion compensation information. The method includes restoring the current image based on the received reference image of the current image and the generated quantized result of the error image representing the difference between the current image and the prediction image. Receiving the reference image of the current image is performed while restoring a previous image, and restoring the current image is performed while receiving a reference image of a subsequent image.
