Abstract:
Provided are a method and apparatus for moving a multi-media file using a Universal Unique IDentifier (UUID) of a capture device, and a storage medium storing a program for executing the multi-media file moving method. The multi-media file moving method includes the operations of receiving unique identifier information about the device from the device, checking whether a directory having a name based on the unique identifier information exists in the storage device, generating the directory based on the unique identifier information if the directory does not exist in the storage device, and storing the multi-media file received from the device in the directory. Accordingly, a media file a user desires can be easily searched.
Abstract:
An apparatus and method for backing up broadcast files are provided. The apparatus includes a received file information analysis unit which analyzes package information included in a metadata file received from the digital broadcast apparatus and extracts storage location information and/or file name information regarding a broadcast file corresponding to the metadata file from the package information; a file request unit which transmits a message to the digital broadcast apparatus requesting the broadcast data file obtained by the received file information analysis unit; and a storage unit which receives the broadcast data file from the digital broadcast apparatus and stores the broadcast data file together with the metadata file in response to the message. Accordingly, it is possible to back up broadcast data files on a storage medium with a large storage capacity by referencing respective corresponding metadata files that are packaged together with the broadcast data files.
Abstract:
A method and apparatus for synchronizing metadata of different assets referencing the same contents, using a backward-link information file of an asset when metadata of the asset is edited, the method including: editing a metadata of a first asset; detecting a second asset referencing the same content as the first asset using a backward-link information file of content which the first asset refers to; and synchronizing metadata of the second asset with the edited metadata of the first asset. Therefore, it is possible to easily synchronize metadata of assets in a plurality of MPV files referencing the same content.
Abstract:
A method and apparatus for reproducing multimedia data using a MusicPhotoVideo (MPV) profile. The method for reproducing multimedia data using a profile complying with the MPV standard, includes: detecting a reference element indicating that a predetermined profile among a plurality of supported profiles is used, in an MPV document; updating the MPV document using information on a profile corresponding to the detected reference element; and reproducing multimedia data by parsing the updated MPV document. Accordingly, by using the MPV standard profile, multimedia data can be reproduced more efficiently.
Abstract:
Provided are an apparatus and method for enabling Power Line Control (PLC) devices to work like Universal Plug And Play (UPnP) devices by allowing the PLC devices to participate in a UPnP network. A bridging apparatus for enabling the UPnP device to control the PLC device includes a unit for generating a device description XML document for each device type using information on the PLC devices and transmitting the same document to a UPnP control point; a unit for, upon receipt of a control command from the control point, converting the control command into a control command conforming to a PLC protocol and transmitting the converted control command to a PLC device, and for, upon receipt of an information packet conforming to the PLC protocol from the PLC device, converting the packet to an event message conforming to a UPnP protocol and transmitting the event message to the control point.
Abstract:
A method and apparatus are provided for creating a MultiPhoto Video or MusicPhoto Video (MPV) file that enables minimization of resources and/or storage capacity required to use the MPV file in a multimedia application environment, and a storage medium having recorded thereon a computer readable program for performing the method. The method includes: generating profilebag elements based on multimedia content; generating unique identification information of assets included in the multimedia content; generating a last uniform resource locator (LastURL) based on universal resource identifiers (URIs) of the assets included in the multimedia content; and creating an MPV file corresponding to the multimedia content using the profilebag elements, the unique identification information of the assets, and the LastURL. Accordingly, the MPV file, which is available to multimedia reproducing devices having limited resources and/or storage capacity, can be provided.
Abstract:
Provided are a method and apparatus for setting the time of a real-time clock included in a digital broadcast receiver. Since the digital broadcast receiver sets the time of the real-time clock included therein, based on time information contained in a received transport stream, it is possible to synchronize the time of the real-time clock with a reference time based on the time information contained in broadcast data transmitted by a broadcast transmitter. Accordingly, it is possible to minimize time-related errors during the execution of a time-dependent application program such as a scheduled-recording program.
Abstract:
A file management method and apparatus for controlling assets in multimedia appliances and an information recording medium thereof are provided. The file management method for controlling assets in multimedia appliances includes: generating and managing an index file containing information on assets obtained by the multimedia appliances and based on MusicPhotoVideo (MPV). The method and apparatus enable users to conveniently and easily manage assets obtained in multimedia appliances such as a digital still camera.
Abstract:
A cyclic referencing management method and apparatus, a parsing method and apparatus, and a computer readable recording medium storing a program to implement the methods are provided. The method for managing cyclic referencing that may occur by mutual references of assets in a file provided to control assets in a multimedia application environment, includes: detecting an asset generating cyclic referencing; and ignoring the asset generating cycling referencing. According to the methods and apparatuses, cyclic referencing that can occur in a file to control assets can be detected and processed such that the system can be prevented from entering an indefinite loop or causing an erroneous operation.
