A method and apparatus controls an MTP device to manage a media file transmitted by an MTP host. According to the method, when the number of files in a folder assigned by the MTP host is equal to or more than a predetermined number while storing a media file received from the MTP host, the MTP device generates a new folder and stores the corresponding media file in the new folder. Accordingly, the files within the predetermined number can be stored in one file. Since the number of files stored in one folder is limited, delay in processing media files due to the large number of files can be reduced.

An apparatus and method for controlling a USB operation, whereby the USB operation can be controlled without unplugging a USB cable while maintaining a charge state from a host device. The USB apparatus includes a USB connector to which a USB cable connected to a host device is connected, and a switching unit to switch to one of a first operation mode, in which data communication with the host device is enabled, and a second operation mode, in which an operation depending on a user input is enabled and data communication with the host device is disabled, by controlling power lines and data lines of the USB cable via the USB connector, wherein power can be charged from the host device in both the first operation mode and the second operation mode. Accordingly, a user can switch a USB operation mode without unplugging the USB cable.

A method for managing multimedia data includes: (a) allowing a user to access a multimedia object including at least one multimedia data file; (b) checking a reference relation of the multimedia data file when the multimedia object is deleted; and (c) deleting the multimedia data file when the multimedia data file is referenced only by the multimedia object, or maintaining the multimedia data file when the multimedia file is referred to by another object as well as the multimedia object.
摘要:
An apparatus, a method, and a system for controlling communications between a host device and a USB device. The apparatus includes a controller to perform an operation for communication between a first device and a second device, and a first processor to selectively stop the operation of the controller according to information indicating a status of the communication between the first device and the second device. Thus, the USB device can perform a unique function even when the USB device is connected to the host via USB.

A method and apparatus for formatting a portable storage device, which are capable of performing formatting optimized for a non-volatile memory of the portable storage device. The method includes: detecting whether file system information is initialized when formatting of the non-volatile memory is started; if the initialization of the non-volatile memory is detected, detecting a cluster size and cluster start position of a storage space of the portable storage device; and if the detected cluster size and the cluster start position information do not match a size and a staring position of a minimum recording unit of the storage space, performing a re-formatting operation of the portable storage device.

Provided are a method and apparatus for storing multimedia data in a nonvolatile storage device in units of blocks, in which the time required for storing the multimedia data in the nonvolatile storage device can be reduced. The method includes receiving the multimedia data, sequentially storing the received multimedia data in a block in which all pages are empty among blocks included in a nonvolatile memory, and searching in the nonvolatile memory for a fragmented block in which some pages are occupied by data and moving the pages of the fragmented block that are occupied by data to another block.

A method of determining a filename of a digital content file generated by a CE product in accordance with a PSFS standard and an apparatus for generating a digital content file are provided. The method of determining a filename of a digital content file includes generating a first character string identifying an apparatus for generating the digital content file, generating a second character string representing a storing order of the digital content file, and determining the filename of the digital content file based on the first and second character strings. Furthermore, the second character string of the digital content file is generated by increasing character code of the second character string of a last-stored digital content file by a predetermined value. Accordingly, it is possible to overcome the limitation on the maximum number of files stored in one directory of the conventional method. In addition, it is possible to keep compatibility with the filenames in accordance with the conventional Digital Content Forum (DCF) standard.
